/**
|

* @description
|
||
*
|
||
* This object provides a utility for producing rich Error messages within
|
||
* Angular. It can be called as follows:
|
||
*
|
||
* var exampleMinErr = minErr('example');
|
||
* throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
|
||
*
|
||
* The above creates an instance of minErr in the example namespace. The
|
||
* resulting error will have a namespaced error code of example.one. The
|
||
* resulting error will replace {0} with the value of foo, and {1} with the
|
||
* value of bar. The object is not restricted in the number of arguments it can
|
||
* take.
|
||
*
|
||
* If fewer arguments are specified than necessary for interpolation, the extra
|
||
* interpolation markers will be preserved in the final string.
|
||
*
|
||
* Since data will be parsed statically during a build step, some restrictions
|
||
* are applied with respect to how minErr instances are created and called.
|
||
* Instances should have names of the form namespaceMinErr for a minErr created
|
||
* using minErr('namespace') . Error codes, namespaces and template strings
|
||
* should all be static strings, not variables or general expressions.
|
||
*
|
||
* @param {string} module The namespace to use for the new minErr instance.
|
||
* @param {function} ErrorConstructor Custom error constructor to be instantiated when returning
|
||
* error from returned function, for cases when a particular type of error is useful.
|
||
* @returns {function(code:string, template:string, ...templateArgs): Error} minErr instance

* @param {angular.Module} ngApp an optional application
|
||
* {@link angular.module module} name to load.
|
||
* @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be

|
||

|
||

|
||
*
|
||
* @description
|
||
*
|
||
* Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
|
||
* designates the **root element** of the application and is typically placed near the root element
|
||
* of the page - e.g. on the `<body>` or `<html>` tags.
|
||
*
|
||
* There are a few things to keep in mind when using `ngApp`:
|
||
* - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
|
||
* found in the document will be used to define the root element to auto-bootstrap as an
|
||
* application. To run multiple applications in an HTML document you must manually bootstrap them using
|
||
* {@link angular.bootstrap} instead.
|
||
* - AngularJS applications cannot be nested within each other.
|
||
* - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
|
||
* This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
|
||
* {@link ngRoute.ngView `ngView`}.
|
||
* Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
|
||
* causing animations to stop working and making the injector inaccessible from outside the app.
|
||
*
|
||
* You can specify an **AngularJS module** to be used as the root module for the application. This
|
||
* module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
|
||
* should contain the application code needed or have dependencies on other modules that will
|
||
* contain the code. See {@link angular.module} for more information.
|
||
*
|
||
* In the example below if the `ngApp` directive were not placed on the `html` element then the
|
||
* document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
|
||
* would not be resolved to `3`.
|
||
*
|
||
* `ngApp` is the easiest, and most common way to bootstrap an application.
|
||
*
|
||
<example module="ngAppDemo" name="ng-app">
|
||
<file name="index.html">
|
||
<div ng-controller="ngAppDemoController">
|
||
I can add: {{a}} + {{b}} = {{ a+b }}

|
||
$scope.a = 1;
|
||
$scope.b = 2;
|
||
});
|
||
</file>
|
||
</example>
|
||
*
|
||
* Using `ngStrictDi`, you would see something like this:
|
||
*
|
||
<example ng-app-included="true" name="strict-di">
|
||
<file name="index.html">
|
||
<div ng-app="ngAppStrictDemo" ng-strict-di>
|
||
<div ng-controller="GoodController1">
|
||
I can add: {{a}} + {{b}} = {{ a+b }}

|
||
*
|
||
* The `angular.module` is a global place for creating, registering and retrieving Angular
|
||
* modules.
|
||
* All modules (angular core or 3rd party) that should be available to an application must be
|
||
* registered using this mechanism.
|
||
*
|
||
* Passing one argument retrieves an existing {@link angular.Module},
|
||
* whereas passing more than one argument creates a new {@link angular.Module}
|
||
*
|
||
*
|
||
* # Module
|
||
*
|
||
* A module is a collection of services, directives, controllers, filters, and configuration information.
|
||
* `angular.module` is used to configure the {@link auto.$injector $injector}.
|
||
*
|
||
* ```js
|
||
* // Create a new module
|
||
* var myModule = angular.module('myModule', []);
|
||
*
|
||
* // register a new service
|
||
* myModule.value('appName', 'MyCoolApp');
|
||
*
|
||
* // configure existing services inside initialization blocks.
|
||
* myModule.config(['$locationProvider', function($locationProvider) {
|
||
* // Configure existing providers
|
||
* $locationProvider.hashPrefix('!');
|
||
* }]);
|
||
* ```
|
||
*
|
||
* Then you can create an injector and load your modules like this:
|
||
*
|
||
* ```js
|
||
* var injector = angular.injector(['ng', 'myModule'])
|
||
* ```
|
||
*
|
||
* However it's more likely that you'll just use
|
||
* {@link ng.directive:ngApp ngApp} or
|
||
* {@link angular.bootstrap} to simplify this process for you.
|
||
*
|
||
* @param {!string} name The name of the module to create or retrieve.
|
||
* @param {!Array.<string>=} requires If specified then new module is being created. If
|
||
* unspecified then the module is being retrieved for further configuration.
|
||
* @param {Function=} configFn Optional configuration function for the module. Same as
|
||
* {@link angular.Module#config Module#config()}.
|
||
* @returns {angular.Module} new module with the {@link angular.Module} api.

|
||
* @kind function
|
||
*
|
||
* @description
|
||
* Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
|
||
*
|
||
* If jQuery is available, `angular.element` is an alias for the
|
||
* [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
|
||
* delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
|
||
*
|
||
* jqLite is a tiny, API-compatible subset of jQuery that allows
|
||
* Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
|
||
* commonly needed functionality with the goal of having a very small footprint.
|
||
*
|
||
* To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
|
||
* {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
|
||
* specific version of jQuery if multiple versions exist on the page.
|
||
*
|
||
* <div class="alert alert-info">**Note:** All element references in Angular are always wrapped with jQuery or
|
||
* jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.</div>
|
||
*
|
||
* <div class="alert alert-warning">**Note:** Keep in mind that this function will not find elements
|
||
* by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
|
||
* or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.</div>
|
||
*
|
||
* ## Angular's jqLite
|
||
* jqLite provides only the following jQuery methods:
|
||
*
|
||
* - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
|
||
* - [`after()`](http://api.jquery.com/after/)
|
||
* - [`append()`](http://api.jquery.com/append/)
|
||
* - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
|
||
* - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData
|
||
* - [`children()`](http://api.jquery.com/children/) - Does not support selectors
|
||
* - [`clone()`](http://api.jquery.com/clone/)
|
||
* - [`contents()`](http://api.jquery.com/contents/)
|
||
* - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
|
||
* As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
|
||
* - [`data()`](http://api.jquery.com/data/)
|
||
* - [`detach()`](http://api.jquery.com/detach/)
|
||
* - [`empty()`](http://api.jquery.com/empty/)
|
||
* - [`eq()`](http://api.jquery.com/eq/)
|
||
* - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
|
||
* - [`hasClass()`](http://api.jquery.com/hasClass/)
|
||
* - [`html()`](http://api.jquery.com/html/)
|
||
* - [`next()`](http://api.jquery.com/next/) - Does not support selectors
|
||
* - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
|
||
* - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
|
||
* - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
|
||
* - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
|
||
* - [`prepend()`](http://api.jquery.com/prepend/)
|
||
* - [`prop()`](http://api.jquery.com/prop/)
|
||
* - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
|
||
* - [`remove()`](http://api.jquery.com/remove/)
|
||
* - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
|
||
* - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
|
||
* - [`removeData()`](http://api.jquery.com/removeData/)
|
||
* - [`replaceWith()`](http://api.jquery.com/replaceWith/)
|
||
* - [`text()`](http://api.jquery.com/text/)
|
||
* - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
|
||
* - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
|
||
* - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter
|
||
* - [`val()`](http://api.jquery.com/val/)
|
||
* - [`wrap()`](http://api.jquery.com/wrap/)
|
||
*
|
||
* ## jQuery/jqLite Extras
|
||
* Angular also provides the following additional methods and events to both jQuery and jqLite:
|
||
*
|
||
* ### Events
|
||
* - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
|
||
* on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM
|
||
* element before it is removed.
|
||
*
|
||
* ### Methods
|
||
* - `controller(name)` - retrieves the controller of the current element or its parent. By default
|
||
* retrieves controller associated with the `ngController` directive. If `name` is provided as
|
||
* camelCase directive name, then the controller for this directive will be retrieved (e.g.
|
||
* `'ngModel'`).
|
||
* - `injector()` - retrieves the injector of the current element or its parent.
|
||
* - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
|
||
* element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
|
||
* be enabled.
|
||
* - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
|
||
* current element. This getter should be used only on elements that contain a directive which starts a new isolate
|
||
* scope. Calling `scope()` on this element always returns the original non-isolate scope.
|
||
* Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
|
||
* - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
|
||
* parent element is reached.
|
||
*
|
||
* @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
|
||
* https://github.com/angular/angular.js/issues/14251 for more information.
|
||
*
|
||
* @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
|
||
* @returns {Object} jQuery object.

|
||
*
|
||
* @param {Array.<string|Function>} modules A list of module functions or their aliases. See

|
||
* disallows argument name annotation inference.
|
||
* @returns {injector} Injector object. See {@link auto.$injector $injector}.
|
||
*
|
||
* @example
|
||
* Typical usage
|
||
* ```js
|
||
* // create an injector
|
||
* var $injector = angular.injector(['ng']);
|
||
*
|
||
* // use the injector to kick off your application
|
||
* // use the type inference to auto inject arguments, or use implicit injection
|
||
* $injector.invoke(function($rootScope, $compile, $document) {
|
||
* $compile($document)($rootScope);
|
||
* $rootScope.$digest();
|
||
* });
|
||
* ```
|
||
*
|
||
* Sometimes you want to get access to the injector of a currently running Angular app
|
||
* from outside Angular. Perhaps, you want to inject and compile some markup after the
|
||
* application has been bootstrapped. You can do this using the extra `injector()` added
|
||
* to JQuery/jqLite elements. See {@link angular.element}.
|
||
*
|
||
* *This is fairly rare but could be the case if a third party library is injecting the
|
||
* markup.*
|
||
*
|
||
* In the following example a new block of HTML containing a `ng-controller`
|
||
* directive is added to the end of the document body by JQuery. We then compile and link
|
||
* it into the current AngularJS scope.
|
||
*
|
||
* ```js
|
||
* var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>');
|
||
* $(document.body).append($div);
|
||
*
|
||
* angular.element(document).injector().invoke(function($compile) {
|
||
* var scope = angular.element($div).scope();
|
||
* $compile($div)(scope);
|
||
* });

* # Injection Function Annotation
|
||
*
|
||
* JavaScript does not have annotations, and annotations are needed for dependency injection. The
|
||
* following are all valid ways of annotating function with injection arguments and are equivalent.
|
||
*
|
||
* ```js
|
||
* // inferred (only works if code not minified/obfuscated)
|
||
* $injector.invoke(function(serviceA){});
|
||
*
|
||
* // annotated
|
||
* function explicit(serviceA) {};
|
||
* explicit.$inject = ['serviceA'];
|
||
* $injector.invoke(explicit);
|
||
*
|
||
* // inline
|
||
* $injector.invoke(['serviceA', function(serviceA){}]);
|
||
* ```
|
||
*
|
||
* ## Inference
|
||
*
|
||
* In JavaScript calling `toString()` on a function returns the function definition. The definition
|
||
* can then be parsed and the function arguments can be extracted. This method of discovering
|
||
* annotations is disallowed when the injector is in strict mode.
|
||
* *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
|
||
* argument names.
|
||
*
|
||
* ## `$inject` Annotation
|
||
* By adding an `$inject` property onto a function the injection parameters can be specified.
|
||
*
|
||
* ## Inline
|
||
* As an array of injection names, where the last item in the array is the function to call.

* function is invoked. There are three ways in which the function can be annotated with the needed
|
||
* dependencies.
|
||
*
|
||
* # Argument names
|
||
*
|
||
* The simplest form is to extract the dependencies from the arguments of the function. This is done
|
||
* by converting the function into a string using `toString()` method and extracting the argument
|
||
* names.
|
||
* ```js
|
||
* // Given
|
||
* function MyController($scope, $route) {
|
||
* // ...
|
||
* }
|
||
*
|
||
* // Then
|
||
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
|
||
* ```
|
||
*
|
||
* You can disallow this method by using strict injection mode.
|
||
*
|
||
* This method does not work with code minification / obfuscation. For this reason the following
|
||
* annotation strategies are supported.
|
||
*
|
||
* # The `$inject` property
|
||
*
|
||
* If a function has an `$inject` property and its value is an array of strings, then the strings
|
||
* represent names of services to be injected into the function.
|
||
* ```js
|
||
* // Given
|
||
* var MyController = function(obfuscatedScope, obfuscatedRoute) {
|
||
* // ...
|
||
* }
|
||
* // Define function dependencies
|
||
* MyController['$inject'] = ['$scope', '$route'];
|
||
*
|
||
* // Then
|
||
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
|
||
* ```
|
||
*
|
||
* # The array notation
|
||
*
|
||
* It is often desirable to inline Injected functions and that's when setting the `$inject` property
|
||
* is very inconvenient. In these situations using the array notation to specify the dependencies in
|
||
* a way that survives minification is a better choice:
|
||
*
|
||
* ```js
|
||
* // We wish to write this (not minification / obfuscation safe)
|
||
* injector.invoke(function($compile, $rootScope) {
|
||
* // ...
|
||
* });
|
||
*
|
||
* // We are forced to write break inlining
|
||
* var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
|
||
* // ...
|
||
* };
|
||
* tmpFn.$inject = ['$compile', '$rootScope'];
|
||
* injector.invoke(tmpFn);
|
||
*
|
||
* // To better support inline function the inline annotation is supported
|
||
* injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
|
||
* // ...
|
||
* }]);
|
||
*
|
||
* // Therefore
|
||
* expect(injector.annotate(
|
||
* ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
|
||
* ).toEqual(['$compile', '$rootScope']);
|
||
* ```
|
||
*
|
||
* @param {Function|Array.<string|Function>} fn Function for which dependent service names need to
|
||
* be retrieved as described above.
|
||
*
|
||
* @param {boolean=} [strictDi=false] Disallow argument name annotation inference.
|
||
*
|
||
* @returns {Array.<string>} The names of the services which the function requires.

* @description
|
||
*
|
||
* The {@link auto.$provide $provide} service has a number of methods for registering components
|
||
* with the {@link auto.$injector $injector}. Many of these functions are also exposed on
|
||
* {@link angular.Module}.
|
||
*
|
||
* An Angular **service** is a singleton object created by a **service factory**. These **service
|
||
* factories** are functions which, in turn, are created by a **service provider**.
|
||
* The **service providers** are constructor functions. When instantiated they must contain a
|
||
* property called `$get`, which holds the **service factory** function.
|
||
*
|
||
* When you request a service, the {@link auto.$injector $injector} is responsible for finding the
|
||
* correct **service provider**, instantiating it and then calling its `$get` **service factory**
|
||
* function to get the instance of the **service**.
|
||
*
|
||
* Often services have no configuration options and there is no need to add methods to the service
|
||
* provider. The provider will be no more than a constructor function with a `$get` property. For
|
||
* these cases the {@link auto.$provide $provide} service has additional helper methods to register
|
||
* services without specifying a provider.
|
||
*
|
||
* * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the
|
||
* {@link auto.$injector $injector}
|
||
* * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by
|
||
* providers and services.
|
||
* * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by
|
||
* services, not providers.
|
||
* * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**
|
||
* that will be wrapped in a **service provider** object, whose `$get` property will contain the
|
||
* given factory function.
|
||
* * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
|
||
* that will be wrapped in a **service provider** object, whose `$get` property will instantiate
|
||
* a new object using the given constructor function.
|
||
* * {@link auto.$provide#decorator decorator(name, decorFn)} - registers a **decorator function** that
|
||
* will be able to modify or replace the implementation of another service.
|
||
*
|
||
* See the individual methods for more information and examples.

|
||
* Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
|
||
* are constructor functions, whose instances are responsible for "providing" a factory for a
|
||
* service.
|
||
*
|
||
* Service provider names start with the name of the service they provide followed by `Provider`.
|
||
* For example, the {@link ng.$log $log} service has a provider called
|
||
* {@link ng.$logProvider $logProvider}.
|
||
*
|
||
* Service provider objects can have additional methods which allow configuration of the provider
|
||
* and its service. Importantly, you can configure what kind of service is created by the `$get`
|
||
* method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
|
||
* method {@link ng.$logProvider#debugEnabled debugEnabled}
|
||
* which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
|
||
* console or not.
|
||
*
|
||
* @param {string} name The name of the instance. NOTE: the provider will be available under `name +
|
||
'Provider'` key.
|
||
* @param {(Object|function())} provider If the provider is:
|
||
*
|
||
* - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
|
||
* {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
|
||
* - `Constructor`: a new instance of the provider will be created using
|
||
* {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
|

*
|
||
* @returns {Object} registered provider instance

* vertical scroll-offset (either fixed or dynamic).
|
||
*
|

*
|

* @property {(number|function|jqLite)} yOffset
|
||
* If set, specifies a vertical scroll-offset. This is often useful when there are fixed
|
||
* positioned elements at the top of the page, such as navbars, headers etc.
|
||
*
|
||
* `yOffset` can be specified in various ways:
|
||
* - **number**: A fixed number of pixels to be used as offset.<br /><br />
|
||
* - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
|
||
* a number representing the offset (in pixels).<br /><br />
|
||
* - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
|
||
* the top of the page to the element's bottom will be used as offset.<br />
|
||
* **Note**: The element will be taken into account only as long as its `position` is set to
|
||
* `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
|
||
* their height and/or positioning according to the viewport's size.

|

|
||
* style in `to`, the style in `from` is applied immediately, and no animation is run.

* @param {object} to the to (destination) CSS styles that will be applied to the element and across the animation.
|

* @param {string=} className an optional CSS class that will be applied to the element for the duration of the animation. If

* Compiles an HTML string or DOM into a template and produces a template function, which
|
||
* can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
|
||
*
|
||
* The compilation is a process of walking the DOM tree and matching DOM elements to
|
||
* {@link ng.$compileProvider#directive directives}.

|

*
|
||
* ## Comprehensive Directive API
|
||
*
|
||
* There are many different options for a directive.
|
||
*
|
||
* The difference resides in the return value of the factory function.
|
||
* You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
|
||
* that defines the directive properties, or just the `postLink` function (all other properties will have
|
||
* the default values).
|
||
*
|
||
* <div class="alert alert-success">
|
||
* **Best Practice:** It's recommended to use the "directive definition object" form.
|
||
* </div>
|
||
*
|
||
* Here's an example directive declared with a Directive Definition Object:
|
||
*
|
||
* ```js
|
||
* var myModule = angular.module(...);
|
||
*
|
||
* myModule.directive('directiveName', function factory(injectables) {
|
||
* var directiveDefinitionObject = {
|
||
* {@link $compile#-priority- priority}: 0,
|
||
* {@link $compile#-template- template}: '<div></div>', // or // function(tElement, tAttrs) { ... },
|
||
* // or
|
||
* // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },
|
||
* {@link $compile#-transclude- transclude}: false,
|
||
* {@link $compile#-restrict- restrict}: 'A',
|
||
* {@link $compile#-templatenamespace- templateNamespace}: 'html',
|
||
* {@link $compile#-scope- scope}: false,
|
||
* {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
|
||
* {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',
|
||
* {@link $compile#-bindtocontroller- bindToController}: false,
|
||
* {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
|
||
* {@link $compile#-multielement- multiElement}: false,
|
||
* {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {
|
||
* return {
|
||
* {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
|
||
* {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
|
||
* }
|
||
* // or
|
||
* // return function postLink( ... ) { ... }
|
||
* },
|
||
* // or
|
||
* // {@link $compile#-link- link}: {
|
||
* // {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
|
||
* // {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
|
||
* // }
|
||
* // or
|
||
* // {@link $compile#-link- link}: function postLink( ... ) { ... }
|
||
* };
|
||
* return directiveDefinitionObject;
|
||
* });
|
||
* ```
|
||
*
|
||
* <div class="alert alert-warning">
|
||
* **Note:** Any unspecified options will use the default value. You can see the default values below.
|
||
* </div>
|
||
*
|
||
* Therefore the above can be simplified as:
|
||
*
|
||
* ```js
|
||
* var myModule = angular.module(...);
|
||
*
|
||
* myModule.directive('directiveName', function factory(injectables) {
|
||
* var directiveDefinitionObject = {
|
||
* link: function postLink(scope, iElement, iAttrs) { ... }
|
||
* };
|
||
* return directiveDefinitionObject;
|
||
* // or
|
||
* // return function postLink(scope, iElement, iAttrs) { ... }
|
||
* });
|
||
* ```
|
||
*
|
||
* ### Life-cycle hooks
|
||
* Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the
|
||
* directive:
|
||
* * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
|
||
* had their bindings initialized (and before the pre & post linking functions for the directives on
|
||
* this element). This is a good place to put initialization code for your controller.
|
||
* * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
|
||
* `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
|
||
* object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
|
||
* component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will
|
||
* also be called when your bindings are initialized.
|
||
* * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
|
||
* changes. Any actions that you wish to take in response to the changes that you detect must be
|
||
* invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
|
||
* could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
|
||
* be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
|
||
* if detecting changes, you must store the previous value(s) for comparison to the current values.
|
||
* * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
|
||
* external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
|
||
* the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
|
||
* components will have their `$onDestroy()` hook called before child components.
|
||
* * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
|
||
* function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
|
||
* Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
|
||
* they are waiting for their template to load asynchronously and their own compilation and linking has been
|
||
* suspended until that occurs.
|
||
*
|
||
* #### Comparison with Angular 2 life-cycle hooks
|
||
* Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are
|
||
* some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:
|
||
*
|
||
* * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.
|
||
* * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.
|
||
* In Angular 2 you can only define hooks on the prototype of the Component class.
|
||
* * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to
|
||
* `ngDoCheck` in Angular 2
|
||
* * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
|
||
* propagated throughout the application.
|
||
* Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
|
||
* error or do nothing depending upon the state of `enableProdMode()`.
|
||
*
|
||
* #### Life-cycle hook examples
|
||
*
|
||
* This example shows how you can check for mutations to a Date object even though the identity of the object
|
||
* has not changed.
|
||
*
|
||
* <example name="doCheckDateExample" module="do-check-module">
|
||
* <file name="app.js">
|
||
* angular.module('do-check-module', [])
|
||
* .component('app', {
|
||
* template:
|
||
* 'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' +
|
||
* 'Date: {{ $ctrl.date }}' +
|
||
* '<test date="$ctrl.date"></test>',
|
||
* controller: function() {
|
||
* this.date = new Date();
|
||
* this.month = this.date.getMonth();
|
||
* this.updateDate = function() {
|
||
* this.date.setMonth(this.month);
|
||
* };
|
||
* }
|
||
* })
|
||
* .component('test', {
|
||
* bindings: { date: '<' },
|
||
* template:
|
||
* '<pre>{{ $ctrl.log | json }}</pre>',
|
||
* controller: function() {
|
||
* var previousValue;
|
||
* this.log = [];
|
||
* this.$doCheck = function() {
|
||
* var currentValue = this.date && this.date.valueOf();
|
||
* if (previousValue !== currentValue) {
|
||
* this.log.push('doCheck: date mutated: ' + this.date);
|
||
* previousValue = currentValue;
|
||
* }
|
||
* };
|
||
* }
|
||
* });
|
||
* </file>
|
||
* <file name="index.html">
|
||
* <app></app>
|
||
* </file>
|
||
* </example>
|
||
*
|
||
* This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
|
||
* actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
|
||
* arrays or objects can have a negative impact on your application performance)
|
||
*
|
||
* <example name="doCheckArrayExample" module="do-check-module">
|
||
* <file name="index.html">
|
||
* <div ng-init="items = []">
|
||
* <button ng-click="items.push(items.length)">Add Item</button>
|
||
* <button ng-click="items = []">Reset Items</button>
|
||
* <pre>{{ items }}</pre>
|
||
* <test items="items"></test>
|
||
* </div>
|
||
* </file>
|
||
* <file name="app.js">
|
||
* angular.module('do-check-module', [])
|
||
* .component('test', {
|
||
* bindings: { items: '<' },
|
||
* template:
|
||
* '<pre>{{ $ctrl.log | json }}</pre>',
|
||
* controller: function() {
|
||
* this.log = [];
|
||
*
|
||
* this.$doCheck = function() {
|
||
* if (this.items_ref !== this.items) {
|
||
* this.log.push('doCheck: items changed');
|
||
* this.items_ref = this.items;
|
||
* }
|
||
* if (!angular.equals(this.items_clone, this.items)) {
|
||
* this.log.push('doCheck: items mutated');
|
||
* this.items_clone = angular.copy(this.items);
|
||
* }
|
||
* };
|
||
* }
|
||
* });
|

|

|
||
* ### Directive Definition Object
|
||
*
|
||
* The directive definition object provides instructions to the {@link ng.$compile
|
||
* compiler}. The attributes are:
|
||
*
|
||
* #### `multiElement`
|
||
* When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between
|
||
* nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
|
||
* together as the directive elements. It is recommended that this feature be used on directives
|
||
* which are not strictly behavioral (such as {@link ngClick}), and which
|
||
* do not manipulate or replace child nodes (such as {@link ngInclude}).
|
||
*
|
||
* #### `priority`
|
||
* When there are multiple directives defined on a single DOM element, sometimes it
|
||
* is necessary to specify the order in which the directives are applied. The `priority` is used
|
||
* to sort the directives before their `compile` functions get called. Priority is defined as a
|
||
* number. Directives with greater numerical `priority` are compiled first. Pre-link functions
|
||
* are also run in priority order, but post-link functions are run in reverse order. The order
|
||
* of directives with the same priority is undefined. The default priority is `0`.
|
||
*
|
||
* #### `terminal`
|
||
* If set to true then the current `priority` will be the last set of directives
|
||
* which will execute (any directives at the current priority will still execute
|
||
* as the order of execution on same `priority` is undefined). Note that expressions
|
||
* and other directives used in the directive's template will also be excluded from execution.
|
||
*
|
||
* #### `scope`
|
||
* The scope property can be `false`, `true`, or an object:
|
||
*
|
||
* * **`false` (default):** No scope will be created for the directive. The directive will use its
|
||
* parent's scope.
|
||
*
|
||
* * **`true`:** A new child scope that prototypically inherits from its parent will be created for
|
||
* the directive's element. If multiple directives on the same element request a new scope,
|
||
* only one new scope is created.
|
||
*
|
||
* * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template.
|
||
* The 'isolate' scope differs from normal scope in that it does not prototypically
|
||
* inherit from its parent scope. This is useful when creating reusable components, which should not
|
||
* accidentally read or modify data in the parent scope. Note that an isolate scope
|
||
* directive without a `template` or `templateUrl` will not apply the isolate scope
|
||
* to its children elements.
|
||
*
|
||
* The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
|
||
* directive's element. These local properties are useful for aliasing values for templates. The keys in
|
||
* the object hash map to the name of the property on the isolate scope; the values define how the property
|
||
* is bound to the parent scope, via matching attributes on the directive's element:
|
||
*
|
||
* * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
|
||
* always a string since DOM attributes are strings. If no `attr` name is specified then the
|
||
* attribute name is assumed to be the same as the local name. Given `<my-component
|
||
* my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`,
|
||
* the directive's scope property `localName` will reflect the interpolated value of `hello
|
||
* {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
|
||
* scope. The `name` is read from the parent scope (not the directive's scope).
|
||
*
|
||
* * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
|
||
* passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
|
||
* If no `attr` name is specified then the attribute name is assumed to be the same as the local
|
||
* name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: {
|
||
* localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
|
||
* value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
|
||
* `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
|
||
* `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
|
||
* optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
|
||
* will be thrown upon discovering changes to the local value, since it will be impossible to sync
|
||
* them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
|
||
* method is used for tracking changes, and the equality check is based on object identity.
|
||
* However, if an object literal or an array literal is passed as the binding expression, the
|
||
* equality check is done by value (using the {@link angular.equals} function). It's also possible
|
||
* to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
|
||
* `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
|
||
*
|
||
* * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an
|
||
* expression passed via the attribute `attr`. The expression is evaluated in the context of the
|
||
* parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the
|
||
* local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`.
|
||
*
|
||
* For example, given `<my-component my-attr="parentModel">` and directive definition of
|
||
* `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the
|
||
* value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
|
||
* in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however
|
||
* two caveats:
|
||
* 1. one-way binding does not copy the value from the parent to the isolate scope, it simply
|
||
* sets the same value. That means if your bound value is an object, changes to its properties
|
||
* in the isolated scope will be reflected in the parent scope (because both reference the same object).
|
||
* 2. one-way binding watches changes to the **identity** of the parent value. That means the
|
||
* {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference
|
||
* to the value has changed. In most cases, this should not be of concern, but can be important
|
||
* to know if you one-way bind to an object, and then replace that object in the isolated scope.
|
||
* If you now change a property of the object in your parent scope, the change will not be
|
||
* propagated to the isolated scope, because the identity of the object on the parent scope
|
||
* has not changed. Instead you must assign a new object.
|
||
*
|
||
* One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings
|
||
* back to the parent. However, it does not make this completely impossible.
|
||
*
|
||
* * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If
|
||
* no `attr` name is specified then the attribute name is assumed to be the same as the local name.
|
||
* Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: {
|
||
* localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
|
||
* the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
|
||
* via an expression to the parent scope. This can be done by passing a map of local variable names
|
||
* and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
|
||
* then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
|
||
*
|
||
* In general it's possible to apply more than one directive to one element, but there might be limitations
|
||
* depending on the type of scope required by the directives. The following points will help explain these limitations.
|
||
* For simplicity only two directives are taken into account, but it is also applicable for several directives:
|
||
*
|
||
* * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
|
||
* * **child scope** + **no scope** => Both directives will share one single child scope
|
||
* * **child scope** + **child scope** => Both directives will share one single child scope
|
||
* * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use
|
||
* its parent's scope
|
||
* * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
|
||
* be applied to the same element.
|
||
* * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives
|
||
* cannot be applied to the same element.
|
||
*
|
||
*
|
||
* #### `bindToController`
|
||
* This property is used to bind scope properties directly to the controller. It can be either
|
||
* `true` or an object hash with the same format as the `scope` property.
|
||
*
|
||
* When an isolate scope is used for a directive (see above), `bindToController: true` will
|
||
* allow a component to have its properties bound to the controller, rather than to scope.
|
||
*
|
||
* After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
|
||
* properties. You can access these bindings once they have been initialized by providing a controller method called
|
||
* `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
|
||
* initialized.
|
||
*
|
||
* <div class="alert alert-warning">
|
||
* **Deprecation warning:** if `$compileProcvider.preAssignBindingsEnabled(true)` was called, bindings for non-ES6 class
|
||
* controllers are bound to `this` before the controller constructor is called but this use is now deprecated. Please
|
||
* place initialization code that relies upon bindings inside a `$onInit` method on the controller, instead.
|
||
* </div>
|
||
*
|
||
* It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
|
||
* This will set up the scope bindings to the controller directly. Note that `scope` can still be used
|
||
* to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
|
||
* scope (useful for component directives).
|
||
*
|
||
* If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
|
||
*
|
||
*
|
||
* #### `controller`
|
||
* Controller constructor function. The controller is instantiated before the
|
||
* pre-linking phase and can be accessed by other directives (see
|
||
* `require` attribute). This allows the directives to communicate with each other and augment
|
||
* each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
|
||
*
|
||
* * `$scope` - Current scope associated with the element
|
||
* * `$element` - Current element
|
||
* * `$attrs` - Current attributes object for the element
|
||
* * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
|
||
* `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
|
||
* * `scope`: (optional) override the scope.
|
||
* * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
|
||
* * `futureParentElement` (optional):
|
||
* * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
|
||
* * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
|
||
* * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
|
||
* and when the `cloneLinkingFn` is passed,
|
||
* as those elements need to created and cloned in a special way when they are defined outside their
|
||
* usual containers (e.g. like `<svg>`).
|
||
* * See also the `directive.templateNamespace` property.
|
||
* * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
|
||
* then the default transclusion is provided.
|
||
* The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
|
||
* `true` if the specified slot contains content (i.e. one or more DOM nodes).
|
||
*
|
||
* #### `require`

* Require another directive and inject its controller as the fourth argument to the linking function. The
|
||
* `require` property can be a string, an array or an object:
|
||
* * a **string** containing the name of the directive to pass to the linking function
|
||
* * an **array** containing the names of directives to pass to the linking function. The argument passed to the
|
||
* linking function will be an array of controllers in the same order as the names in the `require` property
|
||
* * an **object** whose property values are the names of the directives to pass to the linking function. The argument
|
||
* passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
|
||
* controllers.
|
||
*
|
||
* If the `require` property is an object and `bindToController` is truthy, then the required controllers are
|
||
* bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
|
||
* have been constructed but before `$onInit` is called.
|
||
* If the name of the required controller is the same as the local name (the key), the name can be
|
||
* omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
|
||
* See the {@link $compileProvider#component} helper for an example of how this can be used.
|
||
* If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
|
||
* raised (unless no link function is specified and the required controllers are not being bound to the directive
|
||
* controller, in which case error checking is skipped). The name can be prefixed with:
|
||
*
|
||
* * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
|
||
* * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
|
||
* * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
|
||
* * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
|
||
* * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
|
||
* `null` to the `link` fn if not found.
|
||
* * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
|
||
* `null` to the `link` fn if not found.
|
||
*
|
||
*
|
||
* #### `controllerAs`
|
||
* Identifier name for a reference to the controller in the directive's scope.
|
||
* This allows the controller to be referenced from the directive template. This is especially
|
||
* useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
|
||
* to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
|
||
* `controllerAs` reference might overwrite a property that already exists on the parent scope.
|
||
*
|
||
*
|
||
* #### `restrict`
|
||
* String of subset of `EACM` which restricts the directive to a specific directive
|
||
* declaration style. If omitted, the defaults (elements and attributes) are used.
|
||
*
|
||
* * `E` - Element name (default): `<my-directive></my-directive>`
|
||
* * `A` - Attribute (default): `<div my-directive="exp"></div>`
|
||
* * `C` - Class: `<div class="my-directive: exp;"></div>`
|
||
* * `M` - Comment: `<!-- directive: my-directive exp -->`
|
||
*
|
||
*
|
||
* #### `templateNamespace`
|
||
* String representing the document type used by the markup in the template.
|
||
* AngularJS needs this information as those elements need to be created and cloned
|
||
* in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
|
||
*
|
||
* * `html` - All root nodes in the template are HTML. Root nodes may also be
|
||
* top-level elements such as `<svg>` or `<math>`.
|
||
* * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
|
||
* * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
|
||
*
|
||
* If no `templateNamespace` is specified, then the namespace is considered to be `html`.
|
||
*
|
||
* #### `template`
|
||
* HTML markup that may:
|
||
* * Replace the contents of the directive's element (default).
|
||
* * Replace the directive's element itself (if `replace` is true - DEPRECATED).
|
||
* * Wrap the contents of the directive's element (if `transclude` is true).
|
||
*
|
||
* Value may be:
|
||
*
|
||
* * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
|
||
* * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
|
||
* function api below) and returns a string value.
|
||
*
|
||
*
|
||
* #### `templateUrl`
|
||
* This is similar to `template` but the template is loaded from the specified URL, asynchronously.
|
||
*
|
||
* Because template loading is asynchronous the compiler will suspend compilation of directives on that element
|
||
* for later when the template has been resolved. In the meantime it will continue to compile and link
|
||
* sibling and parent elements as though this element had not contained any directives.
|
||
*
|
||
* The compiler does not suspend the entire compilation to wait for templates to be loaded because this
|
||
* would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
|
||
* case when only one deeply nested directive has `templateUrl`.
|
||
*
|
||
* Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
|
||
*
|
||
* You can specify `templateUrl` as a string representing the URL or as a function which takes two
|
||
* arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
|
||
* a string value representing the url. In either case, the template URL is passed through {@link
|
||
* $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
|
||
*
|
||
*
|
||
* #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
|
||
* specify what the template should replace. Defaults to `false`.
|
||
*
|
||
* * `true` - the template will replace the directive's element.
|
||
* * `false` - the template will replace the contents of the directive's element.
|
||
*
|
||
* The replacement process migrates all of the attributes / classes from the old element to the new
|
||
* one. See the {@link guide/directive#template-expanding-directive
|
||
* Directives Guide} for an example.
|
||
*
|
||
* There are very few scenarios where element replacement is required for the application function,
|
||
* the main one being reusable custom components that are used within SVG contexts
|
||
* (because SVG doesn't work with custom elements in the DOM tree).
|
||
*
|
||
* #### `transclude`
|
||
* Extract the contents of the element where the directive appears and make it available to the directive.
|
||
* The contents are compiled and provided to the directive as a **transclusion function**. See the
|
||
* {@link $compile#transclusion Transclusion} section below.
|
||
*
|
||
*
|
||
* #### `compile`
|
||
*
|
||
* ```js
|
||
* function compile(tElement, tAttrs, transclude) { ... }
|
||
* ```
|
||
*
|
||
* The compile function deals with transforming the template DOM. Since most directives do not do
|
||
* template transformation, it is not used often. The compile function takes the following arguments:
|
||
*
|
||
* * `tElement` - template element - The element where the directive has been declared. It is
|
||
* safe to do template transformation on the element and child elements only.
|
||
*
|
||
* * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
|
||
* between all directive compile functions.
|
||
*
|
||
* * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
|
||
*
|
||
* <div class="alert alert-warning">
|
||
* **Note:** The template instance and the link instance may be different objects if the template has
|
||
* been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
|
||
* apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
|
||
* should be done in a linking function rather than in a compile function.
|
||
* </div>
|
||
|
||
* <div class="alert alert-warning">
|
||
* **Note:** The compile function cannot handle directives that recursively use themselves in their
|
||
* own templates or compile functions. Compiling these directives results in an infinite loop and
|
||
* stack overflow errors.
|
||
*
|
||
* This can be avoided by manually using $compile in the postLink function to imperatively compile
|
||
* a directive's template instead of relying on automatic template compilation via `template` or
|
||
* `templateUrl` declaration or manual compilation inside the compile function.
|
||
* </div>
|
||
*
|
||
* <div class="alert alert-danger">
|
||
* **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
|
||
* e.g. does not know about the right outer scope. Please use the transclude function that is passed
|
||
* to the link function instead.
|
||
* </div>
|
||
|
||
* A compile function can have a return value which can be either a function or an object.
|
||
*
|
||
* * returning a (post-link) function - is equivalent to registering the linking function via the
|
||
* `link` property of the config object when the compile function is empty.
|
||
*
|
||
* * returning an object with function(s) registered via `pre` and `post` properties - allows you to
|
||
* control when a linking function should be called during the linking phase. See info about
|
||
* pre-linking and post-linking functions below.
|
||
*
|
||
*
|
||
* #### `link`
|
||
* This property is used only if the `compile` property is not defined.
|
||
*
|
||
* ```js
|
||
* function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
|
||
* ```
|
||
*
|
||
* The link function is responsible for registering DOM listeners as well as updating the DOM. It is
|
||
* executed after the template has been cloned. This is where most of the directive logic will be
|
||
* put.
|
||
*
|
||
* * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
|
||
* directive for registering {@link ng.$rootScope.Scope#$watch watches}.
|
||
*
|
||
* * `iElement` - instance element - The element where the directive is to be used. It is safe to
|
||
* manipulate the children of the element only in `postLink` function since the children have
|
||
* already been linked.
|
||
*
|
||
* * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
|
||
* between all directive linking functions.
|
||
*
|
||
* * `controller` - the directive's required controller instance(s) - Instances are shared
|
||
* among all directives, which allows the directives to use the controllers as a communication
|
||
* channel. The exact value depends on the directive's `require` property:
|
||
* * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
|
||
* * `string`: the controller instance
|
||
* * `array`: array of controller instances
|
||
*
|
||
* If a required controller cannot be found, and it is optional, the instance is `null`,
|
||
* otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
|
||
*
|
||
* Note that you can also require the directive's own controller - it will be made available like
|
||
* any other controller.
|
||
*
|
||
* * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
|
||
* This is the same as the `$transclude` parameter of directive controllers,
|
||
* see {@link ng.$compile#-controller- the controller section for details}.
|
||
* `function([scope], cloneLinkingFn, futureParentElement)`.
|
||
*
|
||
* #### Pre-linking function
|
||
*
|
||
* Executed before the child elements are linked. Not safe to do DOM transformation since the
|
||
* compiler linking function will fail to locate the correct elements for linking.
|
||
*
|
||
* #### Post-linking function
|
||
*
|
||
* Executed after the child elements are linked.
|
||
*
|
||
* Note that child elements that contain `templateUrl` directives will not have been compiled
|
||
* and linked since they are waiting for their template to load asynchronously and their own
|
||
* compilation and linking has been suspended until that occurs.
|
||
*
|
||
* It is safe to do DOM transformation in the post-linking function on elements that are not waiting
|
||
* for their async templates to be resolved.
|
||
*
|
||
*
|
||
* ### Transclusion
|
||
*
|
||
* Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
|
||
* copying them to another part of the DOM, while maintaining their connection to the original AngularJS
|
||
* scope from where they were taken.
|
||
*
|
||
* Transclusion is used (often with {@link ngTransclude}) to insert the
|
||
* original contents of a directive's element into a specified place in the template of the directive.
|
||
* The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
|
||
* content has access to the properties on the scope from which it was taken, even if the directive
|
||
* has isolated scope.
|
||
* See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
|
||
*
|
||
* This makes it possible for the widget to have private state for its template, while the transcluded
|
||
* content has access to its originating scope.
|
||
*
|
||
* <div class="alert alert-warning">
|
||
* **Note:** When testing an element transclude directive you must not place the directive at the root of the
|
||
* DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
|
||
* Testing Transclusion Directives}.
|
||
* </div>
|
||
*
|
||
* There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
|
||
* directive's element, the entire element or multiple parts of the element contents:
|
||
*
|
||
* * `true` - transclude the content (i.e. the child nodes) of the directive's element.
|
||
* * `'element'` - transclude the whole of the directive's element including any directives on this
|
||
* element that defined at a lower priority than this directive. When used, the `template`
|
||
* property is ignored.
|
||
* * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
|
||
*
|
||
* **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
|
||
*
|
||
* This object is a map where the keys are the name of the slot to fill and the value is an element selector
|
||
* used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
|
||
* and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
|
||
*
|
||
* For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
|
||
*
|
||
* If the element selector is prefixed with a `?` then that slot is optional.
|
||
*
|
||
* For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to
|
||
* the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
|
||
*
|
||
* Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
|
||
* in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
|
||
* `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
|
||
* injectable into the directive's controller.
|
||
*
|
||
*
|
||
* #### Transclusion Functions
|
||
*
|
||
* When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
|
||
* function** to the directive's `link` function and `controller`. This transclusion function is a special
|
||
* **linking function** that will return the compiled contents linked to a new transclusion scope.
|
||
*
|
||
* <div class="alert alert-info">
|
||
* If you are just using {@link ngTransclude} then you don't need to worry about this function, since
|
||
* ngTransclude will deal with it for us.
|
||
* </div>
|
||
*
|
||
* If you want to manually control the insertion and removal of the transcluded content in your directive
|
||
* then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
|
||
* object that contains the compiled DOM, which is linked to the correct transclusion scope.
|
||
*
|
||
* When you call a transclusion function you can pass in a **clone attach function**. This function accepts
|
||
* two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
|
||
* content and the `scope` is the newly created transclusion scope, which the clone will be linked to.
|
||
*
|
||
* <div class="alert alert-info">
|
||
* **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
|
||
* since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
|
||
* </div>
|
||
*
|
||
* It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
|
||
* attach function**:
|
||
*
|
||
* ```js
|
||
* var transcludedContent, transclusionScope;
|
||
*
|
||
* $transclude(function(clone, scope) {
|
||
* element.append(clone);
|
||
* transcludedContent = clone;
|
||
* transclusionScope = scope;
|
||
* });
|
||
* ```
|
||
*
|
||
* Later, if you want to remove the transcluded content from your DOM then you should also destroy the
|
||
* associated transclusion scope:
|
||
*
|
||
* ```js
|
||
* transcludedContent.remove();
|
||
* transclusionScope.$destroy();
|
||
* ```
|
||
*
|
||
* <div class="alert alert-info">
|
||
* **Best Practice**: if you intend to add and remove transcluded content manually in your directive
|
||
* (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
|
||
* then you are also responsible for calling `$destroy` on the transclusion scope.
|
||
* </div>
|
||
*
|
||
* The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
|
||
* automatically destroy their transcluded clones as necessary so you do not need to worry about this if
|
||
* you are simply using {@link ngTransclude} to inject the transclusion into your directive.
|
||
*
|
||
*
|
||
* #### Transclusion Scopes
|
||
*
|
||
* When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
|
||
* scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
|
||
* when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
|
||
* was taken.
|
||
*
|
||
* For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
|
||
* like this:
|
||
*
|
||
* ```html
|
||
* <div ng-app>
|
||
* <div isolate>
|
||
* <div transclusion>
|
||
* </div>
|
||
* </div>
|
||
* </div>
|
||
* ```
|
||
*
|
||
* The `$parent` scope hierarchy will look like this:
|
||
*
|
||
```
|
||
- $rootScope
|
||
- isolate
|
||
- transclusion
|
||
```
|
||
*
|
||
* but the scopes will inherit prototypically from different scopes to their `$parent`.
|
||
*
|
||
```
|
||
- $rootScope
|
||
- transclusion
|
||
- isolate
|
||
```
|
||
*
|
||
*
|
||
* ### Attributes
|
||
*
|
||
* The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
|
||
* `link()` or `compile()` functions. It has a variety of uses.
|
||
*
|
||
* * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
|
||
* 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
|
||
* to the attributes.
|
||
*
|
||
* * *Directive inter-communication:* All directives share the same instance of the attributes
|
||
* object which allows the directives to use the attributes object as inter directive
|
||
* communication.
|
||
*
|
||
* * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
|
||
* allowing other directives to read the interpolated value.
|
||
*
|
||
* * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
|
||
* that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
|
||
* the only way to easily get the actual value because during the linking phase the interpolation
|
||
* hasn't been evaluated yet and so the value is at this time set to `undefined`.
|
||
*
|
||
* ```js
|
||
* function linkingFn(scope, elm, attrs, ctrl) {
|
||
* // get the attribute value
|
||
* console.log(attrs.ngModel);
|
||
*
|
||
* // change the attribute
|
||
* attrs.$set('ngModel', 'new value');
|
||
*
|
||
* // observe changes to interpolated attribute
|
||
* attrs.$observe('ngModel', function(value) {
|
||
* console.log('ngModel has changed value to ' + value);
|
||
* });
|
||
* }
|
||
* ```
|
||
*

|
||
*
|
||
* * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
|
||
* * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
|
||
* `template` and call the `cloneAttachFn` function allowing the caller to attach the
|
||
* cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
|
||
* called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
|
||
*
|
||
* * `clonedElement` - is a clone of the original `element` passed into the compiler.
|
||
* * `scope` - is the current scope with which the linking function is working with.
|
||
*
|
||
* * `options` - An optional object hash with linking options. If `options` is provided, then the following
|
||
* keys may be used to control linking behavior:
|
||
*
|
||
* * `parentBoundTranscludeFn` - the transclude function made available to
|
||
* directives; if given, it will be passed through to the link functions of
|
||
* directives found in `element` during compilation.
|
||
* * `transcludeControllers` - an object hash with keys that map controller names
|
||
* to a hash with the key `instance`, which maps to the controller instance;
|
||
* if given, it will make the controllers available to directives on the compileNode:
|
||
* ```
|
||
* {
|
||
* parent: {
|
||
* instance: parentControllerInstance
|
||
* }
|
||
* }
|
||
* ```
|
||
* * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
|
||
* the cloned elements; only needed for transcludes that are allowed to contain non html
|
||
* elements (e.g. SVG elements). See also the directive.controller property.
|
||
*
|
||
* Calling the linking function returns the element of the template. It is either the original
|
||
* element passed in, or the clone of the element if the `cloneAttachFn` is provided.
|
||
*
|
||
* After linking the view is not updated until after a call to $digest which typically is done by
|
||
* Angular automatically.
|
||
*
|
||
* If you need access to the bound view, there are two ways to do it:
|
||
*
|
||
* - If you are not asking the linking function to clone the template, create the DOM element(s)
|
||
* before you send them to the compiler and keep this reference around.
|
||
* ```js
|
||
* var element = $compile('<p>{{total}}</p>')(scope);
|
||
* ```
|
||
*
|
||
* - if on the other hand, you need the element to be cloned, the view reference from the original
|
||
* example would not point to the clone, but rather to the original template that was cloned. In
|
||
* this case, you can access the clone via the cloneAttachFn:
|
||
* ```js
|
||
* var templateElement = angular.element('<p>{{total}}</p>'),
|
||
* scope = ....;
|
||
*
|
||
* var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
|
||
* //attach the clone to DOM document at the right place
|
||
* });
|
||
*
|
||
* //now we have reference to the cloned DOM via `clonedElement`
|
||
* ```
|
||
*
|
||
*
|
||
* For information on how the compiler works, see the
|
||
* {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

|
||
* ### Double Compilation
|
||
*
|
||
Double compilation occurs when an already compiled part of the DOM gets
|
||
compiled again. This is an undesired effect and can lead to misbehaving directives, performance issues,
|
||
and memory leaks. Refer to the Compiler Guide {@link guide/compiler#double-compilation-and-how-to-avoid-it
|
||
section on double compilation} for an in-depth explanation and ways to avoid it.

* @description
|
||
* Register a **component definition** with the compiler. This is a shorthand for registering a special
|
||
* type of directive, which represents a self-contained UI component in your application. Such components
|
||
* are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
|
||
*
|
||
* Component definitions are very simple and do not require as much configuration as defining general
|
||
* directives. Component definitions usually consist only of a template and a controller backing it.
|
||
*
|
||
* In order to make the definition easier, components enforce best practices like use of `controllerAs`,
|
||
* `bindToController`. They always have **isolate scope** and are restricted to elements.
|
||
*
|
||
* Here are a few examples of how you would usually define components:
|
||
*
|
||
* ```js
|
||
* var myMod = angular.module(...);
|
||
* myMod.component('myComp', {
|
||
* template: '<div>My name is {{$ctrl.name}}</div>',
|
||
* controller: function() {
|
||
* this.name = 'shahar';
|
||
* }
|
||
* });
|
||
*
|
||
* myMod.component('myComp', {
|
||
* template: '<div>My name is {{$ctrl.name}}</div>',
|
||
* bindings: {name: '@'}
|
||
* });
|
||
*
|
||
* myMod.component('myComp', {
|
||
* templateUrl: 'views/my-comp.html',
|
||
* controller: 'MyCtrl',
|
||
* controllerAs: 'ctrl',
|
||
* bindings: {name: '@'}
|
||
* });
|
||
*
|
||

* @description
|
||
* The `$http` service is a core Angular service that facilitates communication with the remote
|
||
* HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
|
||
* object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
|
||
*
|
||
* For unit testing applications that use `$http` service, see
|
||
* {@link ngMock.$httpBackend $httpBackend mock}.
|
||
*
|
||
* For a higher level of abstraction, please check out the {@link ngResource.$resource
|
||
* $resource} service.
|
||
*
|
||
* The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
|
||
* the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
|
||
* it is important to familiarize yourself with these APIs and the guarantees they provide.
|
||
*
|
||
*
|
||
* ## General usage
|
||
* The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
|
||
* that is used to generate an HTTP request and returns a {@link ng.$q promise}.
|
||
*
|
||
* ```js
|
||
* // Simple GET request example:
|
||
* $http({
|
||
* method: 'GET',
|
||
* url: '/someUrl'
|
||
* }).then(function successCallback(response) {
|
||
* // this callback will be called asynchronously
|
||
* // when the response is available
|
||
* }, function errorCallback(response) {
|
||
* // called asynchronously if an error occurs
|
||
* // or server returns response with an error status.
|
||
* });
|
||
* ```
|
||
*
|
||
* The response object has these properties:
|
||
*
|
||
* - **data** – `{string|Object}` – The response body transformed with the transform
|
||
* functions.
|
||
* - **status** – `{number}` – HTTP status code of the response.
|
||
* - **headers** – `{function([headerName])}` – Header getter function.
|
||
* - **config** – `{Object}` – The configuration object that was used to generate the request.
|
||
* - **statusText** – `{string}` – HTTP status text of the response.
|
||
*
|
||
* A response status code between 200 and 299 is considered a success status and will result in
|
||
* the success callback being called. Any response status code outside of that range is
|
||
* considered an error status and will result in the error callback being called.
|
||
* Also, status codes less than -1 are normalized to zero. -1 usually means the request was
|
||
* aborted, e.g. using a `config.timeout`.
|
||
* Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning
|
||
* that the outcome (success or error) will be determined by the final response status code.
|
||
*
|
||
*
|
||
* ## Shortcut methods
|
||
*
|
||
* Shortcut methods are also available. All shortcut methods require passing in the URL, and
|
||
* request data must be passed in for POST/PUT requests. An optional config can be passed as the
|
||
* last argument.
|
||
*
|
||
* ```js
|
||
* $http.get('/someUrl', config).then(successCallback, errorCallback);
|
||
* $http.post('/someUrl', data, config).then(successCallback, errorCallback);
|
||
* ```
|
||
*
|
||
* Complete list of shortcut methods:
|
||
*
|
||
* - {@link ng.$http#get $http.get}
|
||
* - {@link ng.$http#head $http.head}
|
||
* - {@link ng.$http#post $http.post}
|
||
* - {@link ng.$http#put $http.put}
|
||
* - {@link ng.$http#delete $http.delete}

* - {@link ng.$http#jsonp $http.jsonp}
|
||
* - {@link ng.$http#patch $http.patch}
|
||
*
|
||
*
|
||
* ## Writing Unit Tests that use $http
|
||
* When unit testing (using {@link ngMock ngMock}), it is necessary to call
|
||
* {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
|
||
* request using trained responses.
|
||
*
|
||
* ```
|
||
* $httpBackend.expectGET(...);
|
||
* $http.get(...);
|
||
* $httpBackend.flush();
|
||
* ```
|
||
*
|
||
* ## Setting HTTP Headers
|
||
*
|
||
* The $http service will automatically add certain HTTP headers to all requests. These defaults
|
||
* can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
|
||
* object, which currently contains this default configuration:
|
||
*
|
||
* - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
|
||
* - <code>Accept: application/json, text/plain, \*/\*</code>
|
||
* - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
|
||
* - `Content-Type: application/json`
|
||
* - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
|
||
* - `Content-Type: application/json`
|
||
*
|
||
* To add or overwrite these defaults, simply add or remove a property from these configuration
|
||
* objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
|
||
* with the lowercased HTTP method name as the key, e.g.
|
||
* `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
|
||
*
|
||
* The defaults can also be set at runtime via the `$http.defaults` object in the same
|
||
* fashion. For example:
|
||
*
|
||
* ```
|
||
* module.run(function($http) {
|
||
* $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
|
||
* });
|
||
* ```
|
||
*
|
||
* In addition, you can supply a `headers` property in the config object passed when
|
||
* calling `$http(config)`, which overrides the defaults without changing them globally.
|
||
*
|
||
* To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
|
||
* Use the `headers` property, setting the desired header to `undefined`. For example:
|
||
*
|
||
* ```js
|
||
* var req = {
|
||
* method: 'POST',
|
||
* url: 'http://example.com',
|
||
* headers: {
|
||
* 'Content-Type': undefined
|
||
* },
|
||
* data: { test: 'test' }
|
||
* }
|
||
*
|
||
* $http(req).then(function(){...}, function(){...});
|
||
* ```
|
||
*
|
||
* ## Transforming Requests and Responses
|
||
*
|
||
* Both requests and responses can be transformed using transformation functions: `transformRequest`
|
||
* and `transformResponse`. These properties can be a single function that returns
|
||
* the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
|
||
* which allows you to `push` or `unshift` a new transformation function into the transformation chain.
|
||
*
|
||
* <div class="alert alert-warning">
|
||
* **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
|
||
* That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
|
||
* For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
|
||
* function will be reflected on the scope and in any templates where the object is data-bound.
|
||
* To prevent this, transform functions should have no side-effects.
|
||
* If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
|
||
* </div>
|
||
*
|
||
* ### Default Transformations
|
||
*
|
||
* The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
|
||
* `defaults.transformResponse` properties. If a request does not provide its own transformations
|
||
* then these will be applied.
|
||
*
|
||
* You can augment or replace the default transformations by modifying these properties by adding to or
|
||
* replacing the array.
|
||
*
|
||
* Angular provides the following default transformations:
|
||
*
|
||
* Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
|
||
*
|
||
* - If the `data` property of the request configuration object contains an object, serialize it
|
||
* into JSON format.
|
||
*
|
||
* Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
|
||
*
|
||
* - If XSRF prefix is detected, strip it (see Security Considerations section below).
|
||
* - If JSON response is detected, deserialize it using a JSON parser.
|
||
*
|
||
*
|
||
* ### Overriding the Default Transformations Per Request
|
||
*
|
||
* If you wish to override the request/response transformations only for a single request then provide
|
||
* `transformRequest` and/or `transformResponse` properties on the configuration object passed
|
||
* into `$http`.
|
||
*
|
||
* Note that if you provide these properties on the config object the default transformations will be
|
||
* overwritten. If you wish to augment the default transformations then you must include them in your
|
||
* local transformation array.
|
||
*
|
||
* The following code demonstrates adding a new response transformation to be run after the default response
|
||
* transformations have been run.
|
||
*
|
||
* ```js
|
||
* function appendTransform(defaults, transform) {
|
||
*
|
||
* // We can't guarantee that the default transformation is an array
|
||
* defaults = angular.isArray(defaults) ? defaults : [defaults];
|
||
*
|
||
* // Append the new transformation to the defaults
|
||
* return defaults.concat(transform);
|
||
* }
|
||
*
|
||
* $http({
|
||
* url: '...',
|
||
* method: 'GET',
|
||
* transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
|
||
* return doTransform(value);
|
||
* })
|
||
* });
|
||
* ```
|
||
*
|
||
*
|
||
* ## Caching
|
||
*
|
||
* {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
|
||
* set the config.cache value or the default cache value to TRUE or to a cache object (created
|
||
* with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
|
||
* precedence over the default cache value.
|
||
*
|
||
* In order to:
|
||
* * cache all responses - set the default cache value to TRUE or to a cache object
|
||
* * cache a specific response - set config.cache value to TRUE or to a cache object
|
||
*
|
||
* If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
|
||
* then the default `$cacheFactory("$http")` object is used.
|
||
*
|
||
* The default cache value can be set by updating the
|
||
* {@link ng.$http#defaults `$http.defaults.cache`} property or the
|
||
* {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
|
||
*
|
||
* When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
|
||
* the relevant cache object. The next time the same request is made, the response is returned
|
||
* from the cache without sending a request to the server.
|
||
*
|
||
* Take note that:
|
||
*
|
||
* * Only GET and JSONP requests are cached.
|
||
* * The cache key is the request URL including search parameters; headers are not considered.
|
||
* * Cached responses are returned asynchronously, in the same way as responses from the server.
|
||
* * If multiple identical requests are made using the same cache, which is not yet populated,
|
||
* one request will be made to the server and remaining requests will return the same response.
|
||
* * A cache-control header on the response does not affect if or how responses are cached.
|
||
*
|
||
*
|
||
* ## Interceptors
|
||
*
|
||
* Before you start creating interceptors, be sure to understand the
|
||
* {@link ng.$q $q and deferred/promise APIs}.
|
||
*
|
||
* For purposes of global error handling, authentication, or any kind of synchronous or
|
||
* asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
|
||
* able to intercept requests before they are handed to the server and
|
||
* responses before they are handed over to the application code that
|
||
* initiated these requests. The interceptors leverage the {@link ng.$q
|
||
* promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
|
||
*
|
||
* The interceptors are service factories that are registered with the `$httpProvider` by
|
||
* adding them to the `$httpProvider.interceptors` array. The factory is called and
|
||
* injected with dependencies (if specified) and returns the interceptor.
|
||
*
|
||
* There are two kinds of interceptors (and two kinds of rejection interceptors):
|
||
*
|
||
* * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
|
||
* modify the `config` object or create a new one. The function needs to return the `config`
|
||
* object directly, or a promise containing the `config` or a new `config` object.
|
||
* * `requestError`: interceptor gets called when a previous interceptor threw an error or
|
||
* resolved with a rejection.
|
||
* * `response`: interceptors get called with http `response` object. The function is free to
|
||
* modify the `response` object or create a new one. The function needs to return the `response`
|
||
* object directly, or as a promise containing the `response` or a new `response` object.
|
||
* * `responseError`: interceptor gets called when a previous interceptor threw an error or
|
||
* resolved with a rejection.
|
||
*
|
||
*
|
||
* ```js
|
||
* // register the interceptor as a service
|
||
* $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
|
||
* return {
|
||
* // optional method
|
||
* 'request': function(config) {
|
||
* // do something on success
|
||
* return config;
|
||
* },
|
||
*
|
||
* // optional method
|
||
* 'requestError': function(rejection) {
|
||
* // do something on error
|
||
* if (canRecover(rejection)) {
|
||
* return responseOrNewPromise
|
||
* }
|
||
* return $q.reject(rejection);
|
||
* },
|
||
*
|
||
*
|
||
*
|
||
* // optional method
|
||
* 'response': function(response) {
|
||
* // do something on success
|
||
* return response;
|
||
* },
|
||
*
|
||
* // optional method
|
||
* 'responseError': function(rejection) {
|
||
* // do something on error
|
||
* if (canRecover(rejection)) {
|
||
* return responseOrNewPromise
|
||
* }
|
||
* return $q.reject(rejection);
|
||
* }
|
||
* };
|
||
* });
|
||
*
|
||
* $httpProvider.interceptors.push('myHttpInterceptor');
|
||
*
|
||
*
|
||
* // alternatively, register the interceptor via an anonymous factory
|
||
* $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
|
||
* return {
|
||
* 'request': function(config) {
|
||
* // same as above
|
||
* },
|
||
*
|
||
* 'response': function(response) {
|
||
* // same as above
|
||
* }
|
||
* };
|
||
* });
|
||
* ```
|
||
*
|
||
* ## Security Considerations
|
||
*
|
||
* When designing web applications, consider security threats from:
|
||
*
|
||
* - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
|
||
* - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
|
||
*
|
||
* Both server and the client must cooperate in order to eliminate these threats. Angular comes
|
||
* pre-configured with strategies that address these issues, but for this to work backend server
|
||
* cooperation is required.
|
||
*
|
||
* ### JSON Vulnerability Protection
|
||
*
|
||
* A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
|
||
* allows third party website to turn your JSON resource URL into
|
||
* [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
|
||
* counter this your server can prefix all JSON requests with following string `")]}',\n"`.
|
||
* Angular will automatically strip the prefix before processing it as JSON.
|
||
*
|
||
* For example if your server needs to return:
|
||
* ```js
|
||
* ['one','two']
|
||
* ```
|
||
*
|
||
* which is vulnerable to attack, your server can return:
|
||
* ```js
|
||
* )]}',
|
||
* ['one','two']
|
||
* ```
|
||
*
|
||
* Angular will strip the prefix, before processing the JSON.
|
||
*
|
||
*
|
||
* ### Cross Site Request Forgery (XSRF) Protection
|
||
*
|
||
* [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
|
||
* which the attacker can trick an authenticated user into unknowingly executing actions on your
|
||
* website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
|
||
* $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
|
||
* header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
|
||
* cookie, your server can be assured that the XHR came from JavaScript running on your domain.
|
||
* The header will not be set for cross-domain requests.
|
||
*
|
||
* To take advantage of this, your server needs to set a token in a JavaScript readable session
|
||
* cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
|
||
* server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
|
||
* that only JavaScript running on your domain could have sent the request. The token must be
|
||
* unique for each user and must be verifiable by the server (to prevent the JavaScript from
|
||
* making up its own tokens). We recommend that the token is a digest of your site's
|
||
* authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
|
||
* for added security.
|
||
*
|
||
* The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
|
||
* properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
|
||
* or the per-request config object.
|
||
*
|
||
* In order to prevent collisions in environments where multiple Angular apps share the
|
||
* same domain or subdomain, we recommend that each application uses unique cookie name.
|
||
*
|
||
* @param {object} config Object describing the request to be made and how it should be
|
||
* processed. The object has following properties:
|
||
*
|
||
* - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
|
||
* - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;
|
||
* or an object created by a call to `$sce.trustAsResourceUrl(url)`.
|
||
* - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized
|
||
* with the `paramSerializer` and appended as GET parameters.
|
||
* - **data** – `{string|Object}` – Data to be sent as the request message data.
|
||
* - **headers** – `{Object}` – Map of strings or functions which return strings representing
|
||
* HTTP headers to send to the server. If the return value of a function is null, the
|
||
* header will not be sent. Functions accept a config object as an argument.
|
||
* - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
|
||
* To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
|
||
* The handler will be called in the context of a `$apply` block.
|
||
* - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
|
||
* object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
|
||
* The handler will be called in the context of a `$apply` block.
|
||
* - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
|
||
* - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
|
||
* - **transformRequest** –
|
||
* `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
|
||
* transform function or an array of such functions. The transform function takes the http
|
||
* request body and headers and returns its transformed (typically serialized) version.
|
||
* See {@link ng.$http#overriding-the-default-transformations-per-request
|
||
* Overriding the Default Transformations}
|
||
* - **transformResponse** –
|
||
* `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
|
||
* transform function or an array of such functions. The transform function takes the http
|
||
* response body, headers and status and returns its transformed (typically deserialized) version.
|
||
* See {@link ng.$http#overriding-the-default-transformations-per-request
|
||
* Overriding the Default Transformations}
|
||
* - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to
|
||
* prepare the string representation of request parameters (specified as an object).
|
||
* If specified as string, it is interpreted as function registered with the
|
||
* {@link $injector $injector}, which means you can create your own serializer
|
||
* by registering it as a {@link auto.$provide#service service}.
|
||
* The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
|
||
* alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
|
||
* - **cache** – `{boolean|Object}` – A boolean value or object created with
|
||
* {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
|
||
* See {@link $http#caching $http Caching} for more information.
|
||
* - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
|
||
* that should abort the request when resolved.
|
||
* - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
|
||
* XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
|
||
* for more information.
|
||
* - **responseType** - `{string}` - see
|
||
* [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
|
||
*
|
||
* @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
|
||
* when the request succeeds or fails.
|
||
*
|
||
*
|
||
* @property {Array.<Object>} pendingRequests Array of config objects for currently pending
|
||
* requests. This is primarily meant to be used for debugging purposes.

|

* setting the `jsonpCallbackParam` property on the request config object.

* ```
|

|

* Compiles a string with markup into an interpolation function. This service is used by the
|

* HTML {@link ng.$compile $compile} service for data binding. See
|
||
* {@link ng.$interpolateProvider $interpolateProvider} for configuring the
|
||
* interpolation markup.
|
||
*
|
||
*
|
||
* ```js
|
||
* var $interpolate = ...; // injected
|
||
* var exp = $interpolate('Hello {{name | uppercase}}!');
|
||
* expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
|
||
* ```
|
||
*
|
||
* `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
|
||
* `true`, the interpolation function will return `undefined` unless all embedded expressions
|
||
* evaluate to a value other than `undefined`.
|
||
*
|
||
* ```js
|
||
* var $interpolate = ...; // injected
|
||
* var context = {greeting: 'Hello', name: undefined };
|
||
*
|
||
* // default "forgiving" mode
|
||
* var exp = $interpolate('{{greeting}} {{name}}!');
|
||
* expect(exp(context)).toEqual('Hello !');
|
||
*
|
||
* // "allOrNothing" mode
|
||
* exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
|
||
* expect(exp(context)).toBeUndefined();
|
||
* context.name = 'Angular';
|
||
* expect(exp(context)).toEqual('Hello Angular!');
|
||
* ```
|
||
*
|
||
* `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
|
||
*
|
||
* #### Escaped Interpolation
|
||
* $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
|
||
* can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
|
||
* It will be rendered as a regular start/end marker, and will not be interpreted as an expression
|
||
* or binding.
|
||
*
|
||
* This enables web-servers to prevent script injection attacks and defacing attacks, to some
|
||
* degree, while also enabling code examples to work without relying on the
|
||
* {@link ng.directive:ngNonBindable ngNonBindable} directive.
|
||
*
|
||
* **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
|
||
* replacing angle brackets (<, >) with &lt; and &gt; respectively, and replacing all
|
||
* interpolation start/end markers with their escaped counterparts.**
|
||
*
|
||
* Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
|
||
* output when the $interpolate service processes the text. So, for HTML elements interpolated
|
||
* by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
|
||
* set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
|
||
* this is typically useful only when user-data is used in rendering a template from the server, or
|
||
* when otherwise untrusted data is used by a directive.
|
||
*
|
||
* <example name="interpolation">
|
||
* <file name="index.html">
|
||
* <div ng-init="username='A user'">
|
||
* <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
|
||
* </p>
|
||
* <p><strong>{{username}}</strong> attempts to inject code which will deface the
|
||
* application, but fails to accomplish their task, because the server has correctly
|
||
* escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
|
||
* characters.</p>
|
||
* <p>Instead, the result of the attempted script injection is visible, and can be removed
|
||
* from the database by an administrator.</p>
|
||
* </div>
|
||
* </file>
|
||
* </example>
|
||
*
|
||
* @knownIssue
|
||
* It is currently not possible for an interpolated expression to contain the interpolation end
|
||
* symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
|
||
* an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
|
||
*
|
||
* @knownIssue
|
||
* All directives and components must use the standard `{{` `}}` interpolation symbols
|
||
* in their templates. If you change the application interpolation symbols the {@link $compile}
|
||
* service will attempt to denormalize the standard symbols to the custom symbols.
|
||
* The denormalization process is not clever enough to know not to replace instances of the standard
|
||
* symbols where they would not normally be treated as interpolation symbols. For example in the following
|
||
* code snippet the closing braces of the literal object will get incorrectly denormalized:
|
||
*
|
||
* ```
|
||
* <div data-context='{"context":{"id":3,"type":"page"}}">
|
||
* ```
|
||
*
|
||
* The workaround is to ensure that such instances are separated by whitespace:
|
||
* ```
|
||
* <div data-context='{"context":{"id":3,"type":"page"} }">
|
||
* ```

|

*
|
||
* @description
|
||
* Angular's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
|
||
* milliseconds.
|
||
*
|
||
* The return value of registering an interval function is a promise. This promise will be
|
||
* notified upon each tick of the interval, and will be resolved after `count` iterations, or
|
||
* run indefinitely if `count` is not defined. The value of the notification will be the
|
||
* number of iterations that have run.
|
||
* To cancel an interval, call `$interval.cancel(promise)`.
|
||
*
|
||
* In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
|
||
* move forward by `millis` milliseconds and trigger any functions scheduled to run in that
|
||
* time.
|
||
*
|
||
* <div class="alert alert-warning">
|
||
* **Note**: Intervals created by this service must be explicitly destroyed when you are finished
|
||
* with them. In particular they are not automatically destroyed when a controller's scope or a
|
||
* directive's element are destroyed.
|
||
* You should take this into consideration and make sure to always cancel the interval at the
|
||
* appropriate moment. See the example below for more details on how and when to do this.
|
||
* </div>
|
||
*
|
||
* @param {function()} fn A function that should be called repeatedly. If no additional arguments
|
||
* are passed (see below), the function is called with the current iteration count.
|
||
* @param {number} delay Number of milliseconds between each function call.
|
||
* @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
|
||
* indefinitely.
|
||
* @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
|
||
* will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
|
||
* @param {...*=} Pass additional parameters to the executed function.
|
||
* @returns {promise} A promise which will be notified on each iteration. It will resolve once all iterations of the interval complete.

* @name $parseProvider#setIdentifierFns
|
||
*
|
||
* @description
|
||
*
|
||
* Allows defining the set of characters that are allowed in Angular expressions. The function
|
||
* `identifierStart` will get called to know if a given character is a valid character to be the
|
||
* first character for an identifier. The function `identifierContinue` will get called to know if
|
||
* a given character is a valid character to be a follow-up identifier character. The functions
|
||
* `identifierStart` and `identifierContinue` will receive as arguments the single character to be
|
||
* identifier and the character code point. These arguments will be `string` and `numeric`. Keep in
|
||
* mind that the `string` parameter can be two characters long depending on the character
|
||
* representation. It is expected for the function to return `true` or `false`, whether that
|
||
* character is allowed or not.
|
||
*
|
||
* Since this function will be called extensively, keep the implementation of these functions fast,
|
||
* as the performance of these functions have a direct impact on the expressions parsing speed.
|
||
*
|
||
* @param {function=} identifierStart The function that will decide whether the given character is
|
||
* a valid identifier start character.
|
||
* @param {function=} identifierContinue The function that will decide whether the given character is
|
||
* a valid identifier continue character.

/**

||
* @ngdoc service
|
||
* @name $q
|
||
* @requires $rootScope
|
||
*
|
||
* @description
|
||
* A service that helps you run functions asynchronously, and use their return values (or exceptions)
|
||
* when they are done processing.
|
||
*
|
||
* This is a [Promises/A+](https://promisesaplus.com/)-compliant implementation of promises/deferred
|
||
* objects inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
|
||
*
|
||
* $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
|
||
* implementations, and the other which resembles ES6 (ES2015) promises to some degree.
|
||
*
|
||
* # $q constructor
|
||
*
|
||
* The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
|
||
* function as the first argument. This is similar to the native Promise implementation from ES6,
|
||
* see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
|
||
*
|
||
* While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
|
||
* available yet.
|
||
*
|
||
* It can be used like so:
|
||
*
|
||
* ```js
|
||
* // for the purpose of this example let's assume that variables `$q` and `okToGreet`
|
||
* // are available in the current lexical scope (they could have been injected or passed in).
|
||
*
|
||
* function asyncGreet(name) {
|
||
* // perform some asynchronous operation, resolve or reject the promise when appropriate.
|
||
* return $q(function(resolve, reject) {
|
||
* setTimeout(function() {
|
||
* if (okToGreet(name)) {
|
||
* resolve('Hello, ' + name + '!');
|
||
* } else {
|
||
* reject('Greeting ' + name + ' is not allowed.');
|
||
* }
|
||
* }, 1000);
|
||
* });
|
||
* }
|
||
*
|
||
* var promise = asyncGreet('Robin Hood');
|
||
* promise.then(function(greeting) {
|
||
* alert('Success: ' + greeting);
|
||
* }, function(reason) {
|
||
* alert('Failed: ' + reason);
|
||
* });
|
||
* ```
|
||
*
|
||
* Note: progress/notify callbacks are not currently supported via the ES6-style interface.
|
||
*
|
||
* Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
|
||
*
|
||
* However, the more traditional CommonJS-style usage is still available, and documented below.
|
||
*
|
||
* [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
|
||
* interface for interacting with an object that represents the result of an action that is
|
||
* performed asynchronously, and may or may not be finished at any given point in time.
|
||
*
|
||
* From the perspective of dealing with error handling, deferred and promise APIs are to
|
||
* asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
|
||
*
|
||
* ```js
|
||
* // for the purpose of this example let's assume that variables `$q` and `okToGreet`
|
||
* // are available in the current lexical scope (they could have been injected or passed in).
|
||
*
|
||
* function asyncGreet(name) {
|
||
* var deferred = $q.defer();
|
||
*
|
||
* setTimeout(function() {
|
||
* deferred.notify('About to greet ' + name + '.');
|
||
*
|
||
* if (okToGreet(name)) {
|
||
* deferred.resolve('Hello, ' + name + '!');
|
||
* } else {
|
||
* deferred.reject('Greeting ' + name + ' is not allowed.');
|
||
* }
|
||
* }, 1000);
|
||
*
|
||
* return deferred.promise;
|
||
* }
|
||
*
|
||
* var promise = asyncGreet('Robin Hood');
|
||
* promise.then(function(greeting) {
|
||
* alert('Success: ' + greeting);
|
||
* }, function(reason) {
|
||
* alert('Failed: ' + reason);
|
||
* }, function(update) {
|
||
* alert('Got notification: ' + update);
|
||
* });
|
||
* ```
|
||
*
|
||
* At first it might not be obvious why this extra complexity is worth the trouble. The payoff
|
||
* comes in the way of guarantees that promise and deferred APIs make, see
|
||
* https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
|
||
*
|
||
* Additionally the promise api allows for composition that is very hard to do with the
|
||
* traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
|
||
* For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
|
||
* section on serial or parallel joining of promises.
|
||
*
|
||
* # The Deferred API
|
||
*
|
||
* A new instance of deferred is constructed by calling `$q.defer()`.
|
||
*
|
||
* The purpose of the deferred object is to expose the associated Promise instance as well as APIs
|
||
* that can be used for signaling the successful or unsuccessful completion, as well as the status
|
||
* of the task.
|
||
*
|
||
* **Methods**
|
||
*
|
||
* - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
|
||
* constructed via `$q.reject`, the promise will be rejected instead.
|
||
* - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
|
||
* resolving it with a rejection constructed via `$q.reject`.
|
||
* - `notify(value)` - provides updates on the status of the promise's execution. This may be called
|
||
* multiple times before the promise is either resolved or rejected.
|
||
*
|
||
* **Properties**
|
||
*
|
||
* - promise – `{Promise}` – promise object associated with this deferred.
|
||
*
|
||
*
|
||
* # The Promise API
|
||
*
|
||
* A new promise instance is created when a deferred instance is created and can be retrieved by
|
||
* calling `deferred.promise`.
|
||
*
|
||
* The purpose of the promise object is to allow for interested parties to get access to the result
|
||
* of the deferred task when it completes.
|
||
*
|
||
* **Methods**
|
||
*
|
||
* - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
|
||
* will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
|
||
* as soon as the result is available. The callbacks are called with a single argument: the result
|
||
* or rejection reason. Additionally, the notify callback may be called zero or more times to
|
||
* provide a progress indication, before the promise is resolved or rejected.
|
||
*
|
||
* This method *returns a new promise* which is resolved or rejected via the return value of the
|
||
* `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
|
||
* with the value which is resolved in that promise using
|
||
* [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
|
||
* It also notifies via the return value of the `notifyCallback` method. The promise cannot be
|
||
* resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
|
||
* arguments are optional.
|
||
*
|
||
* - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
|
||
*
|
||
* - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
|
||
* but to do so without modifying the final value. This is useful to release resources or do some
|
||
* clean-up that needs to be done whether the promise was rejected or resolved. See the [full
|
||
* specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
|
||
* more information.
|
||
*
|
||
* # Chaining promises
|
||
*
|
||
* Because calling the `then` method of a promise returns a new derived promise, it is easily
|
||
* possible to create a chain of promises:
|
||
*
|
||
* ```js
|
||
* promiseB = promiseA.then(function(result) {
|
||
* return result + 1;
|
||
* });
|
||
*
|
||
* // promiseB will be resolved immediately after promiseA is resolved and its value
|
||
* // will be the result of promiseA incremented by 1
|
||
* ```
|
||
*
|
||
* It is possible to create chains of any length and since a promise can be resolved with another
|
||
* promise (which will defer its resolution further), it is possible to pause/defer resolution of
|
||
* the promises at any point in the chain. This makes it possible to implement powerful APIs like
|
||
* $http's response interceptors.
|
||
*
|
||
*
|
||
* # Differences between Kris Kowal's Q and $q
|
||
*
|
||
* There are two main differences:
|
||
*
|
||
* - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
|
||
* mechanism in angular, which means faster propagation of resolution or rejection into your
|
||
* models and avoiding unnecessary browser repaints, which would result in flickering UI.
|
||
* - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
|
||
* all the important functionality needed for common async tasks.
|
||
*
|
||
* # Testing
|
||
*
|
||
* ```js
|
||
* it('should simulate promise', inject(function($q, $rootScope) {
|
||
* var deferred = $q.defer();
|
||
* var promise = deferred.promise;
|
||
* var resolvedValue;
|
||
*
|
||
* promise.then(function(value) { resolvedValue = value; });
|
||
* expect(resolvedValue).toBeUndefined();
|
||
*
|
||
* // Simulate resolving of promise
|
||
* deferred.resolve(123);
|
||
* // Note that the 'then' function does not get called synchronously.
|
||
* // This is because we want the promise API to always be async, whether or not
|
||
* // it got called synchronously or asynchronously.
|
||
* expect(resolvedValue).toBeUndefined();
|
||
*
|
||
* // Propagate promise resolution to 'then' functions using $apply().
|
||
* $rootScope.$apply();
|
||
* expect(resolvedValue).toEqual(123);
|
||
* }));
|
||
* ```
|
||
*
|
||
* @param {function(function, function)} resolver Function which is responsible for resolving or
|
||
* rejecting the newly created promise. The first parameter is a function which resolves the
|
||
* promise, the second parameter is a function which rejects the promise.
|
||
*
|
||
* @returns {Promise} The newly created promise.

|
||
* `reject`.
|
||
*
|
||
* ```js
|

* promiseB = promiseA.then(function(result) {

* // error: handle the error if possible and

|

* if (canHandle(reason)) {

|
||
* DESIGN NOTES
|
||
*
|
||
* The design decisions behind the scope are heavily favored for speed and memory consumption.
|
||
*
|
||
* The typical use of scope is to watch the expressions, which most of the time return the same
|
||
* value as last time so we optimize the operation.
|
||
*
|
||
* Closures construction is expensive in terms of speed as well as memory:
|
||
* - No closures, instead use prototypical inheritance for API
|
||
* - Internal state needs to be stored on scope directly, which means that private state is
|
||
* exposed as $$____ properties
|
||
*
|
||
* Loop operations are optimized by using while(count--) { ... }
|
||
* - This means that in order to keep the same order of execution as addition we have to add
|
||
* items to the array at the beginning (unshift) instead of at the end (push)
|
||
*
|
||
* Child scopes are created and removed often
|
||
* - Using an array would be slow since inserts in the middle are expensive; so we use linked lists
|
||
*
|
||
* There are fewer watches than observers. This is why you don't want the observer to be implemented
|
||
* in the same way as watch. Watch requires return of the initialization function which is expensive
|
||
* to construct.

* A root scope can be retrieved using the {@link ng.$rootScope $rootScope} key from the
|
||
* {@link auto.$injector $injector}. Child scopes are created using the
|
||
* {@link ng.$rootScope.Scope#$new $new()} method. (Most scopes are created automatically when
|
||
* compiled HTML template is executed.) See also the {@link guide/scope Scopes guide} for
|
||
* an in-depth introduction and usage examples.
|
||
*
|
||
*
|
||
* # Inheritance
|
||
* A scope can inherit from a parent scope, as in this example:
|
||
* ```js
|
||
var parent = $rootScope;
|
||
var child = parent.$new();
|
||
|
||
parent.salutation = "Hello";
|
||
expect(child.salutation).toEqual('Hello');
|
||
|
||
child.salutation = "Welcome";
|
||
expect(child.salutation).toEqual('Welcome');
|
||
expect(parent.salutation).toEqual('Hello');
|
||
* ```
|
||
*
|
||
* When interacting with `Scope` in tests, additional helper methods are available on the
|
||
* instances of `Scope` type. See {@link ngMock.$rootScope.Scope ngMock Scope} for additional
|
||
* details.
|
||
*
|
||
*
|
||
* @param {Object.<string, function()>=} providers Map of service factory which need to be
|
||
* provided for the current scope. Defaults to {@link ng}.
|
||
* @param {Object.<string, *>=} instanceCache Provides pre-instantiated services which should
|
||
* append/override services provided by `providers`. This is handy
|
||
* when unit-testing and having the need to override a default
|
||
* service.
|
||
* @returns {Object} Newly created scope.

|
||
* @kind function
|
||
*
|
||
* @description
|
||
* Registers a `listener` callback to be executed whenever the `watchExpression` changes.
|
||
*
|
||
* - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
|
||
* $digest()} and should return the value that will be watched. (`watchExpression` should not change
|
||
* its value when executed multiple times with the same input because it may be executed multiple
|
||
* times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
|
||
* [idempotent](http://en.wikipedia.org/wiki/Idempotence).)
|
||
* - The `listener` is called only when the value from the current `watchExpression` and the
|
||
* previous call to `watchExpression` are not equal (with the exception of the initial run,
|
||
* see below). Inequality is determined according to reference inequality,
|
||
* [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
|
||
* via the `!==` Javascript operator, unless `objectEquality == true`
|
||
* (see next point)
|
||
* - When `objectEquality == true`, inequality of the `watchExpression` is determined
|
||
* according to the {@link angular.equals} function. To save the value of the object for
|
||
* later comparison, the {@link angular.copy} function is used. This therefore means that
|
||
* watching complex objects will have adverse memory and performance implications.
|
||
* - This should not be used to watch for changes in objects that are
|
||
* or contain [File](https://developer.mozilla.org/docs/Web/API/File) objects due to limitations with {@link angular.copy `angular.copy`}.
|
||
* - The watch `listener` may change the model, which may trigger other `listener`s to fire.
|
||
* This is achieved by rerunning the watchers until no changes are detected. The rerun
|
||
* iteration limit is 10 to prevent an infinite loop deadlock.
|
||
*
|
||
*
|
||
* If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
|
||
* you can register a `watchExpression` function with no `listener`. (Be prepared for
|
||
* multiple calls to your `watchExpression` because it will execute multiple times in a
|
||
* single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
|
||
*
|
||
* After a watcher is registered with the scope, the `listener` fn is called asynchronously
|
||
* (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
|
||
* watcher. In rare cases, this is undesirable because the listener is called when the result
|
||
* of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
|
||
* can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
|
||
* listener was called due to initialization.
|
||
*
|
||
*

||
*

|
||
*
|
||
* @description
|
||
* Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
|
||
* its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
|
||
* the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
|
||
* until no more listeners are firing. This means that it is possible to get into an infinite
|
||
* loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
|
||
* iterations exceeds 10.
|
||
*
|
||
* Usually, you don't call `$digest()` directly in
|
||
* {@link ng.directive:ngController controllers} or in
|
||
* {@link ng.$compileProvider#directive directives}.
|
||
* Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
|
||
* a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
|
||
*
|
||
* If you want to be notified whenever `$digest()` is called,
|
||
* you can register a `watchExpression` function with
|
||
* {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
|
||
*
|
||
* In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
|
||
*
|
||
* # Example
|
||
* ```js
|
||
var scope = ...;
|
||
scope.name = 'misko';
|
||
scope.counter = 0;
|
||
|
||
expect(scope.counter).toEqual(0);

|

* `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
|
||
* Contextual Escaping (SCE)} services to AngularJS.
|
||
*
|
||
* For an overview of this service and the functionnality it provides in AngularJS, see the main
|
||
* page for {@link ng.$sce SCE}. The current page is targeted for developers who need to alter how
|
||
* SCE works in their application, which shouldn't be needed in most cases.
|
||
*
|
||
* <div class="alert alert-danger">
|
||
* AngularJS strongly relies on contextual escaping for the security of bindings: disabling or
|
||
* modifying this might cause cross site scripting (XSS) vulnerabilities. For libraries owners,
|
||
* changes to this service will also influence users, so be extra careful and document your changes.
|
||
* </div>
|
||
*
|
||
* Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
|
||
* the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS. This is
|
||
* because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
|
||
* override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
|
||
* work because `$sce` delegates to `$sceDelegate` for these operations.
|
||
*
|
||
* Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
|
||
*
|
||
* The default instance of `$sceDelegate` should work out of the box with little pain. While you
|
||
* can override it completely to change the behavior of `$sce`, the common case would
|
||
* involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
|
||
* your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
|
||
* templates. Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist

|

* The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate
|
||
* $sceDelegate service}, used as a delegate for {@link ng.$sce Strict Contextual Escaping (SCE)}.
|
||
*
|
||
* The `$sceDelegateProvider` allows one to get/set the whitelists and blacklists used to ensure
|
||
* that the URLs used for sourcing AngularJS templates and other script-running URLs are safe (all
|
||
* places that use the `$sce.RESOURCE_URL` context). See
|
||
* {@link ng.$sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider.resourceUrlWhitelist}
|
||
* and
|
||
* {@link ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist},
|
||
*
|
||
* For the general details about this service in Angular, read the main page for {@link ng.$sce
|
||
* Strict Contextual Escaping (SCE)}.
|
||
*
|
||
* **Example**: Consider the following case. <a name="example"></a>
|
||
*
|
||
* - your app is hosted at url `http://myapp.example.com/`
|
||
* - but some of your templates are hosted on other domains you control such as
|
||
* `http://srv01.assets.example.com/`, `http://srv02.assets.example.com/`, etc.
|
||
* - and you have an open redirect at `http://myapp.example.com/clickThru?...`.
|
||
*
|
||
* Here is what a secure configuration for this scenario might look like:
|
||
*
|
||
* ```
|
||
* angular.module('myApp', []).config(function($sceDelegateProvider) {
|
||
* $sceDelegateProvider.resourceUrlWhitelist([
|
||
* // Allow same origin resource loads.
|
||
* 'self',
|
||
* // Allow loading from our assets domain. Notice the difference between * and **.
|
||
* 'http://srv*.assets.example.com/**'
|
||
* ]);
|
||
*
|
||
* // The blacklist overrides the whitelist so the open redirect here is blocked.
|
||
* $sceDelegateProvider.resourceUrlBlacklist([
|
||
* 'http://myapp.example.com/clickThru**'
|
||
* ]);
|
||
* });
|
||
* ```
|
||
* Note that an empty whitelist will block every resource URL from being loaded, and will require
|
||
* you to manually mark each one as trusted with `$sce.trustAsResourceUrl`. However, templates
|
||
* requested by {@link ng.$templateRequest $templateRequest} that are present in
|
||
* {@link ng.$templateCache $templateCache} will not go through this check. If you have a mechanism
|
||
* to populate your templates in that cache at config time, then it is a good idea to remove 'self'
|
||
* from that whitelist. This helps to mitigate the security impact of certain types of issues, like
|
||
* for instance attacker-controlled `ng-includes`.

||
* # Strict Contextual Escaping
|
||
*
|
||
* Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
|
||
* trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
|
||
* (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
|
||
*
|
||
* ## Overview
|
||
*
|
||
* To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
|
||
* HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
|
||
* run security checks on them (sanitizations, whitelists, depending on context), or throw when it
|
||
* cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML
|
||
* can be sanitized, but template URLs cannot, for instance.
|
||
*
|
||
* To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
|
||
* we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
|
||
* before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
|
||
* render the input as-is, you will need to mark it as trusted for that context before attempting
|
||
* to bind it.
|
||
*
|
||
* As of version 1.2, AngularJS ships with SCE enabled by default.
|
||
*
|
||
* ## In practice
|
||
*
|
||
* Here's an example of a binding in a privileged context:
|
||
*
|
||
* ```
|
||
* <input ng-model="userHtml" aria-label="User input">
|
||
* <div ng-bind-html="userHtml"></div>
|
||
* ```
|
||
*
|
||
* Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE
|
||
* disabled, this application allows the user to render arbitrary HTML into the DIV, which would
|
||
* be an XSS security bug. In a more realistic example, one may be rendering user comments, blog
|
||
* articles, etc. via bindings. (HTML is just one example of a context where rendering user
|
||
* controlled input creates security vulnerabilities.)
|
||
*
|
||
* For the case of HTML, you might use a library, either on the client side, or on the server side,
|
||
* to sanitize unsafe HTML before binding to the value and rendering it in the document.
|
||
*
|
||
* How would you ensure that every place that used these types of bindings was bound to a value that
|
||
* was sanitized by your library (or returned as safe for rendering by your server?) How can you
|
||
* ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
|
||
* properties/fields and forgot to update the binding to the sanitized value?
|
||
*
|
||
* To be secure by default, AngularJS makes sure bindings go through that sanitization, or
|
||
* any similar validation process, unless there's a good reason to trust the given value in this
|
||
* context. That trust is formalized with a function call. This means that as a developer, you
|
||
* can assume all untrusted bindings are safe. Then, to audit your code for binding security issues,
|
||
* you just need to ensure the values you mark as trusted indeed are safe - because they were
|
||
* received from your server, sanitized by your library, etc. You can organize your codebase to
|
||
* help with this - perhaps allowing only the files in a specific directory to do this.
|
||
* Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then
|
||
* becomes a more manageable task.
|
||
*
|
||
* In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
|
||
* (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
|
||
* build the trusted versions of your values.
|
||
*
|
||
* ## How does it work?
|
||
*
|
||
* In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
|
||
* $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as
|
||
* a way to enforce the required security context in your data sink. Directives use {@link
|
||
* ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs
|
||
* the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also,
|
||
* when binding without directives, AngularJS will understand the context of your bindings
|
||
* automatically.
|
||
*
|
||
* As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
|
||
* ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
|
||
* simplified):
|
||
*
|
||
* ```
|
||
* var ngBindHtmlDirective = ['$sce', function($sce) {
|
||
* return function(scope, element, attr) {
|
||
* scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
|
||
* element.html(value || '');
|
||
* });
|
||
* };
|
||
* }];
|
||
* ```
|
||
*
|
||
* ## Impact on loading templates
|
||
*
|
||
* This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
|
||
* `templateUrl`'s specified by {@link guide/directive directives}.
|
||
*
|
||
* By default, Angular only loads templates from the same domain and protocol as the application
|
||
* document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
|
||
* $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
|
||
* protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
|
||
* them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
|
||
*
|
||
* *Please note*:
|
||
* The browser's
|
||
* [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
|
||
* and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
|
||
* policy apply in addition to this and may further restrict whether the template is successfully
|
||
* loaded. This means that without the right CORS policy, loading templates from a different domain
|
||
* won't work on all browsers. Also, loading templates from `file://` URL does not work on some
|
||
* browsers.
|
||
*
|
||
* ## This feels like too much overhead
|
||
*
|
||
* It's important to remember that SCE only applies to interpolation expressions.
|
||
*
|
||
* If your expressions are constant literals, they're automatically trusted and you don't need to
|
||
* call `$sce.trustAs` on them (e.g.
|
||
* `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works. The `$sceDelegate` will
|
||
* also use the `$sanitize` service if it is available when binding untrusted values to
|
||
* `$sce.HTML` context. AngularJS provides an implementation in `angular-sanitize.js`, and if you
|
||
* wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in
|
||
* your application.
|
||
*
|
||
* The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
|
||
* templates in `ng-include` from your application's domain without having to even know about SCE.
|
||
* It blocks loading templates from other domains or loading templates over http from an https
|
||
* served document. You can change these by setting your own custom {@link
|
||
* ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
|
||
* ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
|
||
*
|
||
* This significantly reduces the overhead. It is far easier to pay the small overhead and have an
|
||
* application that's secure and can be audited to verify that with much more ease than bolting
|
||
* security onto an application later.

|
||
* ## What trusted context types are supported?
|
||
*
|
||
* | Context | Notes |
|
||
* |---------------------|----------------|
|
||
* | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered, and the {@link ngSanitize.$sanitize $sanitize} service is available (implemented by the {@link ngSanitize ngSanitize} module) this will sanitize the value instead of throwing an error. |
|
||
* | `$sce.CSS` | For CSS that's safe to source into the application. Currently, no bindings require this context. Feel free to use it in your own directives. |
|
||
* | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`<a href=`, `<img src=`, and some others sanitize their urls and don't constitute an SCE context.) |
|
||
* | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG`, `VIDEO`, `AUDIO`, `SOURCE`, and `TRACK` (e.g. `IFRAME`, `OBJECT`, etc.) <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does (it's not just the URL that matters, but also what is at the end of it), and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
|
||
* | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently, no bindings require this context. Feel free to use it in your own directives. |
|
||
*
|
||
*
|
||
* Be aware that `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
|
||
* through {@link ng.$sce#getTrusted $sce.getTrusted}. There's no CSS-, URL-, or JS-context bindings
|
||
* in AngularJS currently, so their corresponding `$sce.trustAs` functions aren't useful yet. This
|
||
* might evolve.
|
||
*
|
||
* ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
|
||
*
|
||
* Each element in these arrays must be one of the following:
|
||
*
|
||
* - **'self'**
|
||
* - The special **string**, `'self'`, can be used to match against all URLs of the **same
|
||
* domain** as the application document using the **same protocol**.
|
||
* - **String** (except the special value `'self'`)
|
||
* - The string is matched against the full *normalized / absolute URL* of the resource
|
||
* being tested (substring matches are not good enough.)
|
||
* - There are exactly **two wildcard sequences** - `*` and `**`. All other characters
|
||
* match themselves.
|
||
* - `*`: matches zero or more occurrences of any character other than one of the following 6
|
||
* characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use
|
||
* in a whitelist.
|
||
* - `**`: matches zero or more occurrences of *any* character. As such, it's not
|
||
* appropriate for use in a scheme, domain, etc. as it would match too much. (e.g.
|
||
* http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
|
||
* not have been the intention.) Its usage at the very end of the path is ok. (e.g.
|
||
* http://foo.example.com/templates/**).
|
||
* - **RegExp** (*see caveat below*)
|
||
* - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax
|
||
* (and all the inevitable escaping) makes them *harder to maintain*. It's easy to
|
||
* accidentally introduce a bug when one updates a complex expression (imho, all regexes should
|
||
* have good test coverage). For instance, the use of `.` in the regex is correct only in a
|
||
* small number of cases. A `.` character in the regex used when matching the scheme or a
|
||
* subdomain could be matched against a `:` or literal `.` that was likely not intended. It
|
||
* is highly recommended to use the string patterns and only fall back to regular expressions
|
||
* as a last resort.
|
||
* - The regular expression must be an instance of RegExp (i.e. not a string.) It is
|
||
* matched against the **entire** *normalized / absolute URL* of the resource being tested
|
||
* (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags
|
||
* present on the RegExp (such as multiline, global, ignoreCase) are ignored.
|
||
* - If you are generating your JavaScript from some other templating engine (not
|
||
* recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
|
||
* remember to escape your regular expression (and be aware that you might need more than
|
||
* one level of escaping depending on your templating engine and the way you interpolated
|
||
* the value.) Do make use of your platform's escaping mechanism as it might be good
|
||
* enough before coding your own. E.g. Ruby has
|
||
* [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
|
||
* and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
|
||
* Javascript lacks a similar built in function for escaping. Take a look at Google
|
||
* Closure library's [goog.string.regExpEscape(s)](
|
||
* http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
|
||
*
|
||
* Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

* ## Can I disable SCE completely?
|
||
*
|
||
* Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
|
||
* for little coding overhead. It will be much harder to take an SCE disabled application and
|
||
* either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
|
||
* for cases where you have a lot of existing code that was written before SCE was introduced and
|
||
* you're migrating them a module at a time. Also do note that this is an app-wide setting, so if
|
||
* you are writing a library, you will cause security bugs applications using it.
|
||
*
|
||
* That said, here's how you can completely disable SCE:
|
||
*
|
||
* ```
|
||
* angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
|
||
* // Completely disable SCE. For demonstration purposes only!
|
||
* // Do not use in new projects or libraries.
|
||
* $sceProvider.enabled(false);
|
||
* });
|
||
* ```

||
*

/* Design notes on the default implementation for SCE.
|
||
*
|
||
* The API contract for the SCE delegate
|
||
* -------------------------------------
|
||
* The SCE delegate object must provide the following 3 methods:
|
||
*
|
||
* - trustAs(contextEnum, value)
|
||
* This method is used to tell the SCE service that the provided value is OK to use in the
|
||
* contexts specified by contextEnum. It must return an object that will be accepted by
|
||
* getTrusted() for a compatible contextEnum and return this value.
|
||
*
|
||
* - valueOf(value)
|
||
* For values that were not produced by trustAs(), return them as is. For values that were
|
||
* produced by trustAs(), return the corresponding input value to trustAs. Basically, if
|
||
* trustAs is wrapping the given values into some type, this operation unwraps it when given
|
||
* such a value.
|
||
*
|
||
* - getTrusted(contextEnum, value)
|
||
* This function should return the a value that is safe to use in the context specified by
|
||
* contextEnum or throw and exception otherwise.
|
||
*
|
||
* NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
|
||
* opaque or wrapped in some holder object. That happens to be an implementation detail. For
|
||
* instance, an implementation could maintain a registry of all trusted objects by context. In
|
||
* such a case, trustAs() would return the same object that was passed in. getTrusted() would
|
||
* return the same object passed in if it was found in the registry under a compatible context or
|
||
* throw an exception otherwise. An implementation might only wrap values some of the time based
|
||
* on some criteria. getTrusted() might return a value and not throw an exception for special
|
||
* constants or objects even if not wrapped. All such implementations fulfill this contract.
|
||
*
|
||
*
|
||
* A note on the inheritance model for SCE contexts
|
||
* ------------------------------------------------
|
||
* I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
|
||
* is purely an implementation details.
|
||
*
|
||
* The contract is simply this:
|
||
*
|
||
* getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
|
||
* will also succeed.
|
||
*
|
||
* Inheritance happens to capture this in a natural way. In some future, we may not use
|
||
* inheritance anymore. That is OK because no code outside of sce.js and sceSpecs.js would need to
|
||
* be aware of this detail.

*
|
||
* Implementation Notes for non-IE browsers
|
||
* ----------------------------------------
|
||
* Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
|
||
* results both in the normalizing and parsing of the URL. Normalizing means that a relative
|
||
* URL will be resolved into an absolute URL in the context of the application document.
|
||
* Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
|
||
* properties are all populated to reflect the normalized URL. This approach has wide
|
||
* compatibility - Safari 1+, Mozilla 1+ etc. See
|
||
* http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
|
||
*
|
||
* Implementation Notes for IE
|
||
* ---------------------------
|
||
* IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
|
||
* browsers. However, the parsed components will not be set if the URL assigned did not specify
|
||
* them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
|
||
* work around that by performing the parsing in a 2nd step by taking a previously normalized
|
||
* URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the
|
||
* properties such as protocol, hostname, port, etc.

|

* @description
|
||
* Selects a subset of items from `array` and returns it as a new array.
|
||
*
|
||
* @param {Array} array The source array.
|
||
* <div class="alert alert-info">
|
||
* **Note**: If the array contains objects that reference themselves, filtering is not possible.
|
||
* </div>
|
||
* @param {string|Object|function()} expression The predicate to be used for selecting items from
|
||
* `array`.
|
||
*
|
||
* Can be one of:
|
||
*
|
||
* - `string`: The string is used for matching against the contents of the `array`. All strings or
|
||
* objects with string properties in `array` that match this string will be returned. This also
|
||
* applies to nested object properties.
|
||
* The predicate can be negated by prefixing the string with `!`.
|
||
*
|
||
* - `Object`: A pattern object can be used to filter specific properties on objects contained
|
||
* by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
|
||
* which have property `name` containing "M" and property `phone` containing "1". A special
|
||
* property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
|
||
* against any property of the object or its nested object properties. That's equivalent to the
|
||
* simple substring match with a `string` as described above. The special property name can be
|
||
* overwritten, using the `anyPropertyKey` parameter.
|
||
* The predicate can be negated by prefixing the string with `!`.
|
||
* For example `{name: "!M"}` predicate will return an array of items which have property `name`
|
||
* not containing "M".
|
||
*
|
||
* Note that a named property will match properties on the same level only, while the special
|
||
* `$` property will match properties on the same level or deeper. E.g. an array item like
|
||
* `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
|
||
* **will** be matched by `{$: 'John'}`.
|
||
*
|
||
* - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
|
||
* The function is called for each element of the array, with the element, its index, and
|
||
* the entire array itself as arguments.
|
||
*
|
||
* The final result is an array of those elements that the predicate returned true for.
|
||
*
|
||
* @param {function(actual, expected)|true|false} [comparator] Comparator which is used in
|
||
* determining if values retrieved using `expression` (when it is not a function) should be
|
||
* considered a match based on the the expected value (from the filter expression) and actual
|
||
* value (from the object in the array).
|
||
*
|
||
* Can be one of:
|
||
*
|
||
* - `function(actual, expected)`:
|
||
* The function will be given the object value and the predicate value to compare and
|
||
* should return true if both values should be considered equal.
|
||
*
|
||
* - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
|
||
* This is essentially strict comparison of expected and actual.
|
||
*
|
||
* - `false`: A short hand for a function which will look for a substring match in a case
|
||
* insensitive way. Primitive values are converted to strings. Objects are not compared against
|
||
* primitives, unless they have a custom `toString` method (e.g. `Date` objects).
|
||
*
|
||
*
|
||
* Defaults to `false`.
|
||
*
|
||
* @param {string} [anyPropertyKey] The special property name that matches against any property.
|
||
* By default `$`.

* Formats `date` to a string based on the requested `format`.
|
||
*
|
||
* `format` string can be composed of the following elements:
|
||
*
|
||
* * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
|
||
* * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
|
||
* * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
|
||
* * `'MMMM'`: Month in year (January-December)
|
||
* * `'MMM'`: Month in year (Jan-Dec)
|
||
* * `'MM'`: Month in year, padded (01-12)
|
||
* * `'M'`: Month in year (1-12)
|
||
* * `'LLLL'`: Stand-alone month in year (January-December)
|
||
* * `'dd'`: Day in month, padded (01-31)
|
||
* * `'d'`: Day in month (1-31)
|
||
* * `'EEEE'`: Day in Week,(Sunday-Saturday)
|
||
* * `'EEE'`: Day in Week, (Sun-Sat)
|
||
* * `'HH'`: Hour in day, padded (00-23)
|
||
* * `'H'`: Hour in day (0-23)
|
||
* * `'hh'`: Hour in AM/PM, padded (01-12)
|
||
* * `'h'`: Hour in AM/PM, (1-12)
|
||
* * `'mm'`: Minute in hour, padded (00-59)
|
||
* * `'m'`: Minute in hour (0-59)
|
||
* * `'ss'`: Second in minute, padded (00-59)
|
||
* * `'s'`: Second in minute (0-59)
|
||
* * `'sss'`: Millisecond in second, padded (000-999)
|
||
* * `'a'`: AM/PM marker
|
||
* * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
|
||
* * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
|
||
* * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
|
||
* * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
|
||
* * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
|
||
*
|
||
* `format` string can also be one of the following predefined
|
||
* {@link guide/i18n localizable formats}:
|
||
*
|
||
* * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
|
||
* (e.g. Sep 3, 2010 12:05:08 PM)
|
||
* * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 PM)
|
||
* * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US locale
|
||
* (e.g. Friday, September 3, 2010)
|
||
* * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010)
|
||
* * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)
|
||
* * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
|
||
* * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
|
||
* * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
|
||
*
|
||
* `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
|
||
* `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
|
||
* (e.g. `"h 'o''clock'"`).
|
||
*
|
||
* Any other characters in the `format` string will be output as-is.
|
||
*
|
||
* @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
|
||
* number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
|
||
* shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
|
||
* specified in the string input, the time is considered to be in the local timezone.
|
||
* @param {string=} format Formatting rules (see Description). If not specified,
|
||
* `mediumDate` is used.
|
||
* @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
|
||
* continental US time zone abbreviations, but for general use, use a time zone offset, for
|
||
* example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
|
||
* If not specified, the timezone of the browser will be used.
|
||
* @returns {string} Formatted string or the input if input is not recognized as date/millis.

|
||
* The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
|
||
* for the preceding one. The `expression` is evaluated against each item and the output is used
|
||
* for comparing with other items.
|
||
*
|
||
* You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
|
||
* ascending order.
|
||
*
|
||
* The comparison is done using the `comparator` function. If none is specified, a default, built-in
|
||
* comparator is used (see below for details - in a nutshell, it compares numbers numerically and
|
||
* strings alphabetically).
|
||
*
|
||
* ### Under the hood
|
||
*
|
||
* Ordering the specified `collection` happens in two phases:
|
||
*
|
||
* 1. All items are passed through the predicate (or predicates), and the returned values are saved
|
||
* along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
|
||
* through a predicate that extracts the value of the `label` property, would be transformed to:
|
||
* ```
|
||
* {
|
||
* value: 'foo',
|
||
* type: 'string',
|
||
* index: ...
|
||
* }
|
||
* ```
|
||
* 2. The comparator function is used to sort the items, based on the derived values, types and
|
||
* indices.
|
||
*
|
||
* If you use a custom comparator, it will be called with pairs of objects of the form
|
||
* `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
|
||
* (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
|
||
* second, or `1` otherwise.
|
||
*
|
||
* In order to ensure that the sorting will be deterministic across platforms, if none of the
|
||
* specified predicates can distinguish between two items, `orderBy` will automatically introduce a
|
||
* dummy predicate that returns the item's index as `value`.
|
||
* (If you are using a custom comparator, make sure it can handle this predicate as well.)
|
||
*
|
||
* Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
|
||
* value for an item, `orderBy` will try to convert that object to a primitive value, before passing
|
||
* it to the comparator. The following rules govern the conversion:
|
||
*
|
||
* 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
|
||
* used instead.<br />
|
||
* (If the object has a `valueOf()` method that returns another object, then the returned object
|
||
* will be used in subsequent steps.)
|
||
* 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
|
||
* returns a primitive, its return value will be used instead.<br />
|
||
* (If the object has a `toString()` method that returns another object, then the returned object
|
||
* will be used in subsequent steps.)
|
||
* 3. No conversion; the object itself is used.
|
||
*
|
||
* ### The default comparator
|
||
*
|
||
* The default, built-in comparator should be sufficient for most usecases. In short, it compares
|
||
* numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
|
||
* using their index in the original collection, and sorts values of different types by type.
|
||
*
|
||
* More specifically, it follows these steps to determine the relative order of items:
|
||
*
|
||
* 1. If the compared values are of different types, compare the types themselves alphabetically.
|
||
* 2. If both values are of type `string`, compare them alphabetically in a case- and
|
||
* locale-insensitive way.
|
||
* 3. If both values are objects, compare their indices instead.
|
||
* 4. Otherwise, return:
|
||
* - `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
|
||
* - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
|
||
* - `1`, otherwise.
|
||
*
|
||
* **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
|
||
* saved as numbers and not strings.
|
||
* **Note:** For the purpose of sorting, `null` values are treated as the string `'null'` (i.e.
|
||
* `type: 'string'`, `value: 'null'`). This may cause unexpected sort order relative to
|
||
* other values.
|
||
*
|
||
* @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
|
||
* @param {(Function|string|Array.<Function|string>)=} expression - A predicate (or list of
|
||
* predicates) to be used by the comparator to determine the order of elements.
|
||
*
|
||
* Can be one of:
|
||
*
|
||
* - `Function`: A getter function. This function will be called with each item as argument and
|
||
* the return value will be used for sorting.
|
||
* - `string`: An Angular expression. This expression will be evaluated against each item and the
|
||
* result will be used for sorting. For example, use `'label'` to sort by a property called
|
||
* `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
|
||
* property.<br />
|
||
* (The result of a constant expression is interpreted as a property name to be used for
|
||
* comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
|
||
* property called `special name`.)<br />
|
||
* An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
|
||
* ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
|
||
* (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
|
||
* - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
|
||
* relative order of two items, the next predicate is used as a tie-breaker.
|
||
*
|
||
* **Note:** If the predicate is missing or empty then it defaults to `'+'`.
|
||
*
|
||
* @param {boolean=} reverse - If `true`, reverse the sorting order.
|
||
* @param {(Function)=} comparator - The comparator function used to determine the relative order of
|
||
* value pairs. If omitted, the built-in comparator will be used.
|
||
*
|
||
* @returns {Array} - The sorted array.
|
||
*
|
||
*
|
||
* @example
|
||
* ### Ordering a table with `ngRepeat`
|
||
*
|
||
* The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
|
||
* age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
|
||
* it defaults to the built-in comparator.

* ### Using a custom comparator
|
||
*
|
||
* If you have very specific requirements about the way items are sorted, you can pass your own
|
||
* comparator function. For example, you might need to compare some strings in a locale-sensitive
|
||
* way. (When specifying a custom comparator, you also need to pass a value for the `reverse`
|
||
* argument - passing `false` retains the default sorting order, i.e. ascending.)

|

* In Angular, forms can be nested. This means that the outer form is valid when all of the child
|
||
* forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
|
||
* Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to

* of controls needs to be determined.
|

|
||
* # CSS classes
|
||
* - `ng-valid` is set if the form is valid.
|

* - `ng-invalid` is set if the form is invalid.
|
||
* - `ng-pending` is set if the form is pending.
|
||
* - `ng-pristine` is set if the form is pristine.
|
||
* - `ng-dirty` is set if the form is dirty.
|
||
* - `ng-submitted` is set if the form was submitted.
|
||
*
|
||
* Keep in mind that ngAnimate can detect each of these classes when added and removed.
|

*
|
||
*
|
||
* # Submitting a form and preventing the default action
|

|

* Since the role of forms in client-side Angular applications is different than in classical

* page reload that sends the data to the server. Instead some javascript logic should be triggered
|
||
* to handle the form submission in an application-specific way.
|
||
*
|
||
* For this reason, Angular prevents the default action (form submission to the server) unless the
|
||
* `<form>` element has an `action` attribute specified.
|
||
*
|
||
* You can use one of the following two ways to specify what javascript method should be called when
|
||
* a form is submitted:
|
||
*
|
||
* - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
|
||
* - {@link ng.directive:ngClick ngClick} directive on the first
|
||
* button or input field of type submit (input[type=submit])
|
||
*
|
||
* To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
|
||
* or {@link ng.directive:ngClick ngClick} directives.
|
||
* This is because of the following form submission rules in the HTML specification:
|
||
*
|
||
* - If a form has only one input field then hitting enter in this field triggers form submit
|
||
* (`ngSubmit`)
|
||
* - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
|
||
* doesn't trigger submit
|
||
* - if a form has one or more input fields and one or more buttons or input[type=submit] then
|
||
* hitting enter in any of the input fields will trigger the click handler on the *first* button or
|
||
* input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
|
||
*
|
||
* Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
|
||
* submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
|
||
* to have access to the updated model.
|
||
*
|
||
* ## Animation Hooks
|
||
*
|
||
* Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
|
||
* These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
|
||
* other validations that are performed within the form. Animations in ngForm are similar to how
|
||
* they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
|
||
* as JS animations.
|
||
*
|
||
* The following example shows a simple way to utilize CSS transitions to style a form element
|
||
* that has been rendered as invalid after it has been validated:
|
||
*
|
||
* <pre>
|
||
* //be sure to include ngAnimate as a module to hook into more
|
||
* //advanced animations
|
||
* .my-form {
|
||
* transition:0.5s linear all;
|
||
* background: white;
|
||
* }
|
||
* .my-form.ng-invalid {
|
||
* background: red;
|
||
* color:white;
|
||
* }
|
||
* </pre>

|
||
* @description
|
||
* Standard HTML text input with angular data binding, inherited by most of the `input` elements.
|
||
*
|
||
*
|
||
* @param {string} ngModel Assignable angular expression to data-bind to.
|
||
* @param {string=} name Property name of the form under which the control is published.
|
||
* @param {string=} required Adds `required` validation error key if the value is not entered.
|
||
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
|
||
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
|
||
* `required` when you want to data-bind to the `required` attribute.
|
||
* @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
|
||
* minlength.
|
||
* @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
|
||
* maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
|
||
* any length.
|
||
* @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
|
||
* that contains the regular expression body that will be converted to a regular expression
|
||
* as in the ngPattern directive.
|
||
* @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
|
||
* does not match a RegExp found by evaluating the Angular expression given in the attribute value.
|
||
* If the expression evaluates to a RegExp object, then this is used directly.
|
||
* If the expression evaluates to a string, then it will be converted to a RegExp
|
||
* after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
|
||
* `new RegExp('^abc$')`.<br />
|
||
* **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
|
||
* start at the index of the last search's match, thus not taking the whole input value into
|
||
* account.
|
||
* @param {string=} ngChange Angular expression to be executed when input changes due to user
|
||
* interaction with the input element.
|
||
* @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.
|
||
* This parameter is ignored for input[type=password] controls, which will never trim the
|
||
* input.

|
||
* Input with month validation and transformation. In browsers that do not yet support
|
||
* the HTML5 month input, a text element will be used. In that case, the text must be entered in a valid ISO-8601
|
||
* month format (yyyy-MM), for example: `2009-01`.
|
||
*
|
||
* The model must always be a Date object, otherwise Angular will throw an error.
|
||
* Invalid `Date` objects (dates whose `getTime()` is `NaN`) will be rendered as an empty string.
|
||
* If the model is not set to the first of the month, the next view to model update will set it
|
||
* to the first of the month.
|
||
*
|
||
* The timezone to be used to read/write the `Date` instance in the model can be defined using
|
||
* {@link ng.directive:ngModelOptions ngModelOptions}. By default, this is the timezone of the browser.
|
||
*
|
||
* @param {string} ngModel Assignable angular expression to data-bind to.
|
||
* @param {string=} name Property name of the form under which the control is published.
|
||
* @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
|
||
* This must be a valid ISO month format (yyyy-MM). You can also use interpolation inside this
|
||
* attribute (e.g. `min="{{minMonth | date:'yyyy-MM'}}"`). Note that `min` will also add
|
||
* native HTML5 constraint validation.
|
||
* @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
|
||
* This must be a valid ISO month format (yyyy-MM). You can also use interpolation inside this
|
||
* attribute (e.g. `max="{{maxMonth | date:'yyyy-MM'}}"`). Note that `max` will also add
|
||
* native HTML5 constraint validation.
|
||
* @param {(date|string)=} ngMin Sets the `min` validation constraint to the Date / ISO week string
|
||
* the `ngMin` expression evaluates to. Note that it does not set the `min` attribute.
|
||
* @param {(date|string)=} ngMax Sets the `max` validation constraint to the Date / ISO week string
|
||
* the `ngMax` expression evaluates to. Note that it does not set the `max` attribute.
|
||
|
||
* @param {string=} required Sets `required` validation error key if the value is not entered.
|
||
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
|
||
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
|
||
* `required` when you want to data-bind to the `required` attribute.
|
||
* @param {string=} ngChange Angular expression to be executed when input changes due to user
|
||
* interaction with the input element.

* ## Issues with HTML5 constraint validation
|
||
*
|
||
* In browsers that follow the
|
||
* [HTML5 specification](https://html.spec.whatwg.org/multipage/forms.html#number-state-%28type=number%29),
|
||
* `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
|
||
* If a non-number is entered in the input, the browser will report the value as an empty string,
|
||
* which means the view / model values in `ngModel` and subsequently the scope value
|
||
* will also be an empty string.
|
||
*
|
||
*
|
||
* @param {string} ngModel Assignable angular expression to data-bind to.
|
||
* @param {string=} name Property name of the form under which the control is published.
|
||
* @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
|
||
* Can be interpolated.
|
||
* @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
|
||
* Can be interpolated.
|
||
* @param {string=} ngMin Like `min`, sets the `min` validation error key if the value entered is less than `ngMin`,
|
||
* but does not trigger HTML5 native validation. Takes an expression.
|
||
* @param {string=} ngMax Like `max`, sets the `max` validation error key if the value entered is greater than `ngMax`,
|
||
* but does not trigger HTML5 native validation. Takes an expression.
|
||
* @param {string=} step Sets the `step` validation error key if the value entered does not fit the `step` constraint.
|
||
* Can be interpolated.
|
||
* @param {string=} ngStep Like `step`, sets the `step` validation error key if the value entered does not fit the `ngStep` constraint,
|
||
* but does not trigger HTML5 native validation. Takes an expression.
|
||
* @param {string=} required Sets `required` validation error key if the value is not entered.
|
||
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
|
||
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
|
||
* `required` when you want to data-bind to the `required` attribute.
|
||
* @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
|
||
* minlength.
|
||
* @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
|
||
* maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
|
||
* any length.
|
||
* @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
|
||
* that contains the regular expression body that will be converted to a regular expression
|
||
* as in the ngPattern directive.
|
||
* @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
|
||
* does not match a RegExp found by evaluating the Angular expression given in the attribute value.
|
||
* If the expression evaluates to a RegExp object, then this is used directly.
|
||
* If the expression evaluates to a string, then it will be converted to a RegExp
|
||
* after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
|
||
* `new RegExp('^abc$')`.<br />
|
||
* **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to

/**
|
||
* @ngdoc input
|
||
* @name input[range]
|
||
*
|
||
* @description
|
||
* Native range input with validation and transformation.
|
||
*
|
||
* The model for the range input must always be a `Number`.
|
||
*
|
||
* IE9 and other browsers that do not support the `range` type fall back
|
||
* to a text input without any default values for `min`, `max` and `step`. Model binding,
|
||
* validation and number parsing are nevertheless supported.
|
||
*
|
||
* Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
|
||
* in a way that never allows the input to hold an invalid value. That means:
|
||
* - any non-numerical value is set to `(max + min) / 2`.
|
||
* - any numerical value that is less than the current min val, or greater than the current max val
|
||
* is set to the min / max val respectively.
|
||
* - additionally, the current `step` is respected, so the nearest value that satisfies a step
|
||
* is used.
|
||
*
|
||
* See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
|
||
* for more info.
|
||
*
|
||
* This has the following consequences for Angular:
|
||
*
|
||
* Since the element value should always reflect the current model value, a range input
|
||
* will set the bound ngModel expression to the value that the browser has set for the
|
||
* input element. For example, in the following input `<input type="range" ng-model="model.value">`,
|
||
* if the application sets `model.value = null`, the browser will set the input to `'50'`.
|
||
* Angular will then set the model to `50`, to prevent input and model value being out of sync.
|
||
*
|
||
* That means the model for range will immediately be set to `50` after `ngModel` has been
|
||
* initialized. It also means a range input can never have the required error.
|
||
*
|
||
* This does not only affect changes to the model value, but also to the values of the `min`,
|
||
* `max`, and `step` attributes. When these change in a way that will cause the browser to modify
|
||
* the input value, Angular will also update the model value.
|
||
*
|
||
* Automatic value adjustment also means that a range input element can never have the `required`,
|
||
* `min`, or `max` errors.
|
||
*
|
||
* However, `step` is currently only fully implemented by Firefox. Other browsers have problems
|
||
* when the step value changes dynamically - they do not adjust the element value correctly, but
|
||
* instead may set the `stepMismatch` error. If that's the case, the Angular will set the `step`
|
||
* error on the input, and set the model to `undefined`.
|
||
*
|
||
* Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do
|
||
* not set the `min` and `max` attributes, which means that the browser won't automatically adjust
|
||
* the input value based on their values, and will always assume min = 0, max = 100, and step = 1.

|
||
* @param {string=} name Property name of the form under which the control is published.
|
||
* @param {string=} min Sets the `min` validation to ensure that the value entered is greater

|
||
*
|
||
* You can work around this Internet Explorer issue by using `ng-attr-placeholder` instead of

* @description
|
||
* The `ngBind` attribute tells Angular to replace the text content of the specified HTML element
|
||
* with the value of a given expression, and to update the text content when the value of that
|
||
* expression changes.
|
||
*
|
||
* Typically, you don't use `ngBind` directly, but instead you use the double curly markup like
|
||
* `{{ expression }}` which is similar but less verbose.
|
||
*
|
||
* It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
|
||
* displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
|
||
* element attribute, it makes the bindings invisible to the user while the page is loading.
|
||
*
|
||
* An alternative solution to this problem would be using the

* {@link ng.directive:ngCloak ngCloak} directive.

* @ngdoc directive
|
||
* @name ngClass
|
||
* @restrict AC
|
||
*
|
||
* @description
|
||
* The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
|
||
* an expression that represents all classes to be added.
|
||
*
|
||
* The directive operates in three different ways, depending on which of three types the expression
|
||
* evaluates to:
|
||
*
|
||
* 1. If the expression evaluates to a string, the string should be one or more space-delimited class
|
||
* names.
|
||
*
|
||
* 2. If the expression evaluates to an object, then for each key-value pair of the
|
||
* object with a truthy value the corresponding key is used as a class name.
|
||
*
|
||
* 3. If the expression evaluates to an array, each element of the array should either be a string as in
|
||
* type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
|
||
* to give you more control over what CSS classes appear. See the code below for an example of this.
|
||
*
|
||
*
|
||
* The directive won't add duplicate classes if a particular class was already set.
|
||
*
|
||
* When the expression changes, the previously added classes are removed and only then are the
|
||
* new classes added.
|
||
*
|
||
* @knownIssue
|
||
* You should not use {@link guide/interpolation interpolation} in the value of the `class`
|
||
* attribute, when using the `ngClass` directive on the same element.
|
||
* See {@link guide/interpolation#known-issues here} for more info.

|
||
* @param {expression} ngClass {@link guide/expression Expression} to eval. The result
|
||
* of the evaluation can be a string representing space delimited class
|
||
* names, an array, or a map of class names to boolean values. In the case of a map, the
|
||
* names of the properties whose values are truthy will be added as css classes to the
|
||
* element.

## Animations
|
||
|
||
The example below demonstrates how to perform animations using ngClass.
|
||
|
||
<example module="ngAnimate" deps="angular-animate.js" animations="true" name="ng-class">
|
||
<file name="index.html">
|
||
<input id="setbtn" type="button" value="set" ng-click="myVar='my-class'">
|
||
<input id="clearbtn" type="button" value="clear" ng-click="myVar=''">
|
||
<br>
|
||
<span class="base-class" ng-class="myVar">Sample Text</span>
|
||
</file>
|
||
<file name="style.css">
|
||
.base-class {
|
||
transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
|
||
}
|
||
|
||
.base-class.my-class {
|
||
color: red;
|
||
font-size:3em;
|
||
}
|
||
</file>
|
||
<file name="protractor.js" type="protractor">
|
||
it('should check ng-class', function() {
|
||
expect(element(by.css('.base-class')).getAttribute('class')).not.
|
||
toMatch(/my-class/);
|
||
|
||
element(by.id('setbtn')).click();
|
||
|
||
expect(element(by.css('.base-class')).getAttribute('class')).
|
||
toMatch(/my-class/);
|
||
|
||
element(by.id('clearbtn')).click();
|
||
|
||
expect(element(by.css('.base-class')).getAttribute('class')).not.
|
||
toMatch(/my-class/);
|
||
});
|
||
</file>
|
||
</example>
|
||
|
||
|
||
## ngClass and pre-existing CSS3 Transitions/Animations
|
||
The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
|
||
Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
|
||
any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
|
||
to view the step by step details of {@link $animate#addClass $animate.addClass} and
|
||
{@link $animate#removeClass $animate.removeClass}.

* @description
|
||
* The `ngCloak` directive is used to prevent the Angular html template from being briefly
|
||
* displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
|
||
* directive to avoid the undesirable flicker effect caused by the html template display.
|
||
*
|
||
* The directive can be applied to the `<body>` element, but the preferred usage is to apply
|
||
* multiple `ngCloak` directives to small portions of the page to permit progressive rendering
|
||
* of the browser view.
|
||
*
|
||
* `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
|
||
* `angular.min.js`.
|
||
* For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
|
||
*
|
||
* ```css
|
||
* [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
|
||
* display: none !important;
|
||
* }
|
||
* ```
|
||
*
|
||
* When this css rule is loaded by the browser, all html elements (including their children) that
|
||
* are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
|
||
* during the compilation of the template it deletes the `ngCloak` element attribute, making
|
||
* the compiled element visible.
|
||
*
|
||
* For the best result, the `angular.js` script must be loaded in the head section of the html
|
||
* document; alternatively, the css rule above must be included in the external stylesheet of the
|
||
* application.

|

* @description
|
||
* The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
|
||
* supports the principles behind the Model-View-Controller design pattern.
|
||
*
|
||
* MVC components in angular:
|
||
*
|
||
* * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
|
||
* are accessed through bindings.
|
||
* * View — The template (HTML with data bindings) that is rendered into the View.
|
||
* * Controller — The `ngController` directive specifies a Controller class; the class contains business
|
||
* logic behind the application to decorate the scope with functions and values
|
||
*
|
||
* Note that you can also attach controllers to the DOM by declaring it in a route definition
|
||
* via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
|
||
* again using `ng-controller` in the template itself. This will cause the controller to be attached
|
||
* and executed twice.
|
||
*
|
||
* @element ANY
|
||
* @scope
|
||
* @priority 500
|
||
* @param {expression} ngController Name of a constructor function registered with the current
|
||
* {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
|
||
* that on the current scope evaluates to a constructor function.
|
||
*
|
||
* The controller instance can be published into a scope property by specifying
|
||
* `ng-controller="as propertyName"`.
|
||
*
|
||
* If the current `$controllerProvider` is configured to use globals (via
|
||
* {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
|
||
* also be the name of a globally accessible constructor function (deprecated, not recommended).
|
||
*
|
||
* @example
|
||
* Here is a simple form for editing user contact information. Adding, removing, clearing, and
|
||
* greeting are methods declared on the controller (see source tab). These methods can
|
||
* easily be called from the angular markup. Any changes to the data are automatically reflected
|
||
* in the View without the need for a manual update.
|
||
*
|
||
* Two different declaration styles are included below:
|
||
*
|
||
* * one binds methods and properties directly onto the controller using `this`:
|
||
* `ng-controller="SettingsController1 as settings"`
|
||
* * one injects `$scope` into the controller:
|
||
* `ng-controller="SettingsController2"`
|
||
*
|
||
* The second option is more common in the Angular community, and is generally used in boilerplates
|
||
* and in this guide. However, there are advantages to binding properties directly to the controller
|
||
* and avoiding scope.
|
||
*
|
||
* * Using `controller as` makes it obvious which controller you are accessing in the template when
|
||
* multiple controllers apply to an element.
|
||
* * If you are writing your controllers as classes you have easier access to the properties and
|
||
* methods, which will appear on the scope, from inside the controller code.
|
||
* * Since there is always a `.` in the bindings, you don't have to worry about prototypal
|
||
* inheritance masking primitives.
|
||
*
|
||
* This example demonstrates the `controller as` syntax.

|
||
* @description
|
||
*
|
||
* Angular has some features that can conflict with certain restrictions that are applied when using
|
||
* [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.
|
||
*
|
||
* If you intend to implement CSP with these rules then you must tell Angular not to use these
|
||
* features.
|
||
*
|
||
* This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
|
||
*
|
||
*
|
||
* The following default rules in CSP affect Angular:
|
||
*
|
||
* * The use of `eval()`, `Function(string)` and similar functions to dynamically create and execute
|
||
* code from strings is forbidden. Angular makes use of this in the {@link $parse} service to
|
||
* provide a 30% increase in the speed of evaluating Angular expressions. (This CSP rule can be
|
||
* disabled with the CSP keyword `unsafe-eval`, but it is generally not recommended as it would
|
||
* weaken the protections offered by CSP.)
|
||
*
|
||
* * The use of inline resources, such as inline `<script>` and `<style>` elements, are forbidden.
|
||
* This prevents apps from injecting custom styles directly into the document. Angular makes use of
|
||
* this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}). To make these
|
||
* directives work when a CSP rule is blocking inline styles, you must link to the `angular-csp.css`
|
||
* in your HTML manually. (This CSP rule can be disabled with the CSP keyword `unsafe-inline`, but
|
||
* it is generally not recommended as it would weaken the protections offered by CSP.)
|
||
*
|
||
* If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking dynamic code
|
||
* creation from strings (e.g., `unsafe-eval` not specified in CSP header) and automatically
|
||
* deactivates this feature in the {@link $parse} service. This autodetection, however, triggers a
|
||
* CSP error to be logged in the console:
|
||
*
|
||
* ```
|
||
* Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
|
||
* script in the following Content Security Policy directive: "default-src 'self'". Note that
|
||
* 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
|
||
* ```
|
||
*
|
||
* This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
|
||
* directive on an element of the HTML document that appears before the `<script>` tag that loads
|
||
* the `angular.js` file.
|
||
*
|
||
* *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
|
||
*
|
||
* You can specify which of the CSP related Angular features should be deactivated by providing
|
||
* a value for the `ng-csp` attribute. The options are as follows:
|
||
*
|
||
* * no-inline-style: this stops Angular from injecting CSS styles into the DOM
|
||
*
|
||
* * no-unsafe-eval: this stops Angular from optimizing $parse with unsafe eval of strings
|
||
*
|
||
* You can use these values in the following combinations:
|
||
*
|
||
*
|
||
* * No declaration means that Angular will assume that you can do inline styles, but it will do
|
||
* a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous
|
||
* versions of Angular.
|
||
*
|
||
* * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline
|
||
* styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous
|
||
* versions of Angular.
|
||
*
|
||
* * Specifying only `no-unsafe-eval` tells Angular that we must not use eval, but that we can
|
||
* inject inline styles. E.g. `<body ng-csp="no-unsafe-eval">`.
|
||
*
|
||
* * Specifying only `no-inline-style` tells Angular that we must not inject styles, but that we can
|
||
* run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp="no-inline-style">`
|
||
*
|
||
* * Specifying both `no-unsafe-eval` and `no-inline-style` tells Angular that we must not inject
|
||
* styles nor use eval, which is the same as an empty: ng-csp.
|
||
* E.g.`<body ng-csp="no-inline-style;no-unsafe-eval">`
|
||
*
|
||
* @example
|
||
* This example shows how to apply the `ngCsp` directive to the `html` tag.
|
||
```html
|
||
<!doctype html>
|
||
<html ng-app ng-csp>
|
||
...
|
||
...
|
||

|

* @restrict A
|
||
* @multiElement
|
||
*
|
||
* @description
|
||
* The `ngIf` directive removes or recreates a portion of the DOM tree based on an
|
||
* {expression}. If the expression assigned to `ngIf` evaluates to a false
|
||
* value then the element is removed from the DOM, otherwise a clone of the
|
||
* element is reinserted into the DOM.
|
||
*
|
||
* `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
|
||
* element in the DOM rather than changing its visibility via the `display` css property. A common
|
||
* case when this difference is significant is when using css selectors that rely on an element's
|
||
* position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
|
||
*
|
||
* Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
|
||
* is created when the element is restored. The scope created within `ngIf` inherits from
|
||
* its parent scope using
|
||
* [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
|
||
* An important implication of this is if `ngModel` is used within `ngIf` to bind to
|
||
* a javascript primitive defined in the parent scope. In this case any modifications made to the
|
||
* variable within the child scope will override (hide) the value in the parent scope.
|
||
*
|
||
* Also, `ngIf` recreates elements using their compiled state. An example of this behavior
|
||
* is if an element's class attribute is directly modified after it's compiled, using something like
|
||
* jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
|
||
* the added class will be lost because the original compiled state is used to regenerate the element.
|
||
*
|
||
* Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
|
||
* and `leave` effects.
|
||
*
|
||
* @animations
|

* | Animation | Occurs |

|

* This directive can be abused to add unnecessary amounts of logic into your templates.

* {@link ng.directive:ngRepeat `ngRepeat`}, as seen in the demo below; and for injecting data via
|

|

* **Note**: If you have assignment in `ngInit` along with a {@link ng.$filter `filter`}, make

* @description
|

* Text input that converts between a delimited string and an array of strings. The default
|
||
* delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
|
||
* delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
|
||
*
|
||
* The behaviour of the directive is affected by the use of the `ngTrim` attribute.
|
||
* * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
|
||
* list item is respected. This implies that the user of the directive is responsible for
|
||
* dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
|
||
* tab or newline character.
|
||
* * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
|
||
* when joining the list items back together) and whitespace around each list item is stripped
|
||
* before it is added to the model.

||
* @property {*} $modelValue The value in the model that the control is bound to.
|
||
*
|
||
* @property {Array.<Function>} $parsers Array of functions to execute, as a pipeline, whenever
|
||
* the control updates the ngModelController with a new {@link ngModel.NgModelController#$viewValue
|
||
`$viewValue`} from the DOM, usually via user input.
|
||
See {@link ngModel.NgModelController#$setViewValue `$setViewValue()`} for a detailed lifecycle explanation.
|
||
Note that the `$parsers` are not called when the bound ngModel expression changes programmatically.
|
||
|
||
The functions are called in array order, each passing
|
||
its return value through to the next. The last return value is forwarded to the
|
||
{@link ngModel.NgModelController#$validators `$validators`} collection.
|
||
|
||
Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue
|
||
`$viewValue`}.
|
||
|
||
Returning `undefined` from a parser means a parse error occurred. In that case,
|
||
no {@link ngModel.NgModelController#$validators `$validators`} will run and the `ngModel`
|
||
will be set to `undefined` unless {@link ngModelOptions `ngModelOptions.allowInvalid`}
|
||
is set to `true`. The parse error is stored in `ngModel.$error.parse`.
|
||
|
||
This simple example shows a parser that would convert text input value to lowercase:
|
||
* ```js
|
||
* function parse(value) {
|
||
* if (value) {
|
||
* return value.toLowerCase();
|
||
* }
|
||
* }
|
||
* ngModelController.$parsers.push(parse);
|
||
* ```
|
||
|
||
*
|
||
* @property {Array.<Function>} $formatters Array of functions to execute, as a pipeline, whenever
|
||
the bound ngModel expression changes programmatically. The `$formatters` are not called when the
|
||
value of the control is changed by user interaction.
|
||
|
||
Formatters are used to format / convert the {@link ngModel.NgModelController#$modelValue
|
||
`$modelValue`} for display in the control.
|
||
|
||
The functions are called in reverse array order, each passing the value through to the
|
||
next. The last return value is used as the actual DOM value.
|
||
|
||
This simple example shows a formatter that would convert the model value to uppercase:
|
||
|
||
* ```js
|
||
* function format(value) {
|
||
* if (value) {
|
||
* return value.toUpperCase();
|
||
* }
|
||
* }
|
||
* ngModel.$formatters.push(format);
|
||
* ```
|
||
*
|
||
* @property {Object.<string, function>} $validators A collection of validators that are applied
|
||
* whenever the model value changes. The key value within the object refers to the name of the
|
||
* validator while the function refers to the validation operation. The validation operation is
|
||
* provided with the model value as an argument and must return a true or false value depending
|
||
* on the response of that validation.
|
||
*
|
||
* ```js
|
||
* ngModel.$validators.validCharacters = function(modelValue, viewValue) {
|
||
* var value = modelValue || viewValue;
|
||
* return /[0-9]+/.test(value) &&
|
||
* /[a-z]+/.test(value) &&
|
||
* /[A-Z]+/.test(value) &&
|
||
* /\W+/.test(value);
|
||
* };
|
||
* ```
|
||
*
|
||
* @property {Object.<string, function>} $asyncValidators A collection of validations that are expected to
|
||
* perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
|
||
* is expected to return a promise when it is run during the model validation process. Once the promise
|
||
* is delivered then the validation status will be set to true when fulfilled and false when rejected.
|
||
* When the asynchronous validators are triggered, each of the validators will run in parallel and the model
|
||
* value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
|
||
* is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
|
||
* will only run once all synchronous validators have passed.
|
||
*
|
||
* Please note that if $http is used then it is important that the server returns a success HTTP response code
|
||
* in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
|
||
*
|
||
* ```js
|
||
* ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
|
||
* var value = modelValue || viewValue;
|
||
*
|
||
* // Lookup user by username
|
||
* return $http.get('/api/users/' + value).
|
||
* then(function resolved() {
|
||
* //username exists, this means validation fails
|
||
* return $q.reject('exists');
|
||
* }, function rejected() {
|
||
* //username does not exist, therefore this validation passes
|
||
* return true;
|
||
* });
|
||
* };
|
||
* ```
|
||
*
|
||
* @property {Array.<Function>} $viewChangeListeners Array of functions to execute whenever the
|
||
* view value has changed. It is called with no arguments, and its return value is ignored.
|
||
* This can be used in place of additional $watches against the model value.
|
||
*
|
||
* @property {Object} $error An object hash with all failing validator ids as keys.
|
||
* @property {Object} $pending An object hash with all pending validator ids as keys.
|
||
*
|
||
* @property {boolean} $untouched True if control has not lost focus yet.
|
||
* @property {boolean} $touched True if control has lost focus.
|
||
* @property {boolean} $pristine True if user has not interacted with the control yet.
|
||
* @property {boolean} $dirty True if user has already interacted with the control.
|
||
* @property {boolean} $valid True if there is no error.
|
||
* @property {boolean} $invalid True if at least one error on the control.
|
||

|
||
* `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
|
||
* The controller contains services for data-binding, validation, CSS updates, and value formatting
|
||
* and parsing. It purposefully does not contain any logic which deals with DOM rendering or
|
||
* listening to DOM events.
|
||
* Such DOM related logic should be provided by other directives which make use of
|
||
* `NgModelController` for data-binding to control elements.
|
||
* Angular provides this DOM logic for most {@link input `input`} elements.
|
||
* At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
|
||
* custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
|
||
*
|
||
* @example
|
||
* ### Custom Control Example
|
||
* This example shows how to use `NgModelController` with a custom control to achieve
|
||
* data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
|
||
* collaborate together to achieve the desired result.
|
||
*
|
||
* `contenteditable` is an HTML5 attribute, which tells the browser to let the element
|
||
* contents be edited in place by the user.
|
||
*
|
||
* We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
|
||
* module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
|
||
* However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
|
||
* that content using the `$sce` service.
|
||
*
|
||
* <example name="NgModelController" module="customControl" deps="angular-sanitize.js">

*
|

|
||
*
|
||
* @description
|
||
* Update the view value.
|
||
*
|
||
* This method should be called when a control wants to change the view value; typically,
|
||
* this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
|
||
* directive calls it when the value of the input changes and {@link ng.directive:select select}
|
||
* calls it when an option is selected.
|
||
*
|
||
* When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
|
||
* and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
|
||
* value is sent directly for processing through the `$parsers` pipeline. After this, the `$validators` and
|
||
* `$asyncValidators` are called and the value is applied to `$modelValue`.
|
||
* Finally, the value is set to the **expression** specified in the `ng-model` attribute and
|
||
* all the registered change listeners, in the `$viewChangeListeners` list are called.
|
||
*
|
||
* In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
|
||
* and the `default` trigger is not listed, all those actions will remain pending until one of the
|
||
* `updateOn` events is triggered on the DOM element.
|
||
* All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
|
||
* directive is used with a custom debounce for this particular event.
|
||
* Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
|
||
* is specified, once the timer runs out.
|
||
*
|
||
* When used with standard inputs, the view value will always be a string (which is in some cases
|
||
* parsed into another type, such as a `Date` object for `input[date]`.)
|
||
* However, custom controls might also pass objects to this method. In this case, we should make
|
||
* a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
|
||
* perform a deep watch of objects, it only looks for a change of identity. If you only change
|
||
* the property of the object then ngModel will not realize that the object has changed and
|
||
* will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
|
||
* not change properties of the copy once it has been passed to `$setViewValue`.
|
||
* Otherwise you may cause the model value on the scope to change incorrectly.
|
||
*
|
||
* <div class="alert alert-info">
|
||
* In any case, the value passed to the method should always reflect the current value
|
||
* of the control. For example, if you are calling `$setViewValue` for an input element,
|
||
* you should pass the input DOM value. Otherwise, the control and the scope model become
|
||
* out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
|
||
* the control's DOM value in any way. If we want to change the control's DOM value
|
||
* programmatically, we should update the `ngModel` scope expression. Its new value will be
|
||
* picked up by the model controller, which will run it through the `$formatters`, `$render` it
|
||
* to update the DOM, and finally call `$validate` on it.
|
||
* </div>

|
||
* - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
|

* - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
|

* `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
|

* binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
|
||
* object or collection change, `ngModel` will not be notified and so the input will not be re-rendered.
|
||
*
|
||
* The model must be assigned an entirely new object or collection before a re-rendering will occur.
|
||
*
|
||
* Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
|
||
* - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
|
||
* if the select is given the `multiple` attribute.
|
||
*
|
||
* The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
|
||
* first level of the object (or only changing the properties of an item in the collection if it's an array) will still
|
||
* not trigger a re-rendering of the model.
|
||
*
|
||
* # CSS classes
|
||
* The following CSS classes are added and removed on the associated input/select/textarea element
|
||
* depending on the validity of the model.
|
||
*
|
||
* - `ng-valid`: the model is valid
|
||
* - `ng-invalid`: the model is invalid
|
||
* - `ng-valid-[key]`: for each valid key added by `$setValidity`
|
||
* - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
|
||
* - `ng-pristine`: the control hasn't been interacted with yet
|
||
* - `ng-dirty`: the control has been interacted with
|
||
* - `ng-touched`: the control has been blurred
|
||
* - `ng-untouched`: the control hasn't been blurred
|
||
* - `ng-pending`: any `$asyncValidators` are unfulfilled
|
||
* - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
|
||
* by the {@link ngModel.NgModelController#$isEmpty} method
|
||
* - `ng-not-empty`: the view contains a non-empty value
|
||
*
|
||
* Keep in mind that ngAnimate can detect each of these classes when added and removed.
|
||
*
|
||
* ## Animation Hooks
|
||
*
|
||
* Animations within models are triggered when any of the associated CSS classes are added and removed
|
||
* on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
|
||
* `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
|
||
* The animations that are triggered within ngModel are similar to how they work in ngClass and
|
||
* animations can be hooked into using CSS transitions, keyframes as well as JS animations.
|
||
*
|
||
* The following example shows a simple way to utilize CSS transitions to style an input element
|
||
* that has been rendered as invalid after it has been validated:
|
||
*
|
||
* <pre>
|
||
* //be sure to include ngAnimate as a module to hook into more
|
||
* //advanced animations
|
||
* .my-input {
|
||
* transition:0.5s linear all;
|
||
* background: white;
|
||
* }
|
||
* .my-input.ng-invalid {
|
||
* background: red;
|
||
* color:white;
|
||
* }
|
||
* </pre>
|
||
*
|
||
* @example
|
||
* <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample" name="ng-model">
|
||
<file name="index.html">
|
||
<script>
|
||
angular.module('inputExample', [])
|
||
.controller('ExampleController', ['$scope', function($scope) {
|
||
$scope.val = '1';
|
||
}]);
|
||
</script>
|
||
<style>
|
||
.my-input {
|
||
transition:all linear 0.5s;
|
||
background: transparent;
|
||
}
|
||
.my-input.ng-invalid {
|
||
color:white;
|
||
background: red;
|
||
}
|
||
</style>
|
||
<p id="inputDescription">
|
||
Update input to see transitions when valid/invalid.
|
||
Integer is a valid value.
|
||
</p>
|
||
<form name="testForm" ng-controller="ExampleController">
|
||
<input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input"
|
||
aria-describedby="inputDescription" />
|
||
</form>
|
||
</file>
|
||
* </example>
|
||
*
|
||
* ## Binding to a getter/setter
|
||
*
|
||
* Sometimes it's helpful to bind `ngModel` to a getter/setter function. A getter/setter is a
|
||
* function that returns a representation of the model when called with zero arguments, and sets
|
||
* the internal state of a model when called with an argument. It's sometimes useful to use this
|
||
* for models that have an internal representation that's different from what the model exposes
|
||
* to the view.
|
||
*
|
||
* <div class="alert alert-success">
|
||
* **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
|
||
* frequently than other parts of your code.
|
||
* </div>
|
||
*
|
||
* You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
|
||
* has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
|
||
* a `<form>`, which will enable this behavior for all `<input>`s within it. See
|
||
* {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
|
||
*
|
||
* The following example shows how to use `ngModel` with a getter/setter:
|
||
*
|
||
* @example
|
||
* <example name="ngModel-getter-setter" module="getterSetterExample">
|
||
<file name="index.html">

|
||
ng-model-options="{ getterSetter: true }" />
|
||
</label>
|
||
</form>
|
||
<pre>user.name = <span ng-bind="user.name()"></span></pre>
|
||
</div>

||

||

|
||
var _name = 'Brian';
|
||
$scope.user = {
|
||
name: function(newName) {
|
||
// Note that newName can be undefined for two reasons:
|
||
// 1. Because it is called as a getter and thus called with no arguments
|
||
// 2. Because the property should actually be set to undefined. This happens e.g. if the
|
||
// input is invalid
|
||
return arguments.length ? (_name = newName) : _name;
|
||
}
|

/**

* @ngdoc directive
|
||
* @name ngModelOptions
|
||
*
|
||
* @description
|
||
* This directive allows you to modify the behaviour of {@link ngModel} directives within your
|
||
* application. You can specify an `ngModelOptions` directive on any element. All {@link ngModel}
|
||
* directives will use the options of their nearest `ngModelOptions` ancestor.
|
||
*
|
||
* The `ngModelOptions` settings are found by evaluating the value of the attribute directive as
|
||
* an Angular expression. This expression should evaluate to an object, whose properties contain
|
||
* the settings. For example: `<div "ng-model-options"="{ debounce: 100 }"`.
|
||
*
|
||
* ## Inheriting Options
|
||
*
|
||
* You can specify that an `ngModelOptions` setting should be inherited from a parent `ngModelOptions`
|
||
* directive by giving it the value of `"$inherit"`.
|
||
* Then it will inherit that setting from the first `ngModelOptions` directive found by traversing up the
|
||
* DOM tree. If there is no ancestor element containing an `ngModelOptions` directive then default settings
|
||
* will be used.
|
||
*
|
||
* For example given the following fragment of HTML
|
||
*
|
||
*
|
||
* ```html
|
||
* <div ng-model-options="{ allowInvalid: true, debounce: 200 }">
|
||
* <form ng-model-options="{ updateOn: 'blur', allowInvalid: '$inherit' }">
|
||
* <input ng-model-options="{ updateOn: 'default', allowInvalid: '$inherit' }" />
|
||
* </form>
|
||
* </div>
|
||
* ```
|
||
*
|
||
* the `input` element will have the following settings
|
||
*
|
||
* ```js
|
||
* { allowInvalid: true, updateOn: 'default', debounce: 0 }
|
||
* ```
|
||
*
|
||
* Notice that the `debounce` setting was not inherited and used the default value instead.
|
||
*
|
||
* You can specify that all undefined settings are automatically inherited from an ancestor by
|
||
* including a property with key of `"*"` and value of `"$inherit"`.
|
||
*
|
||
* For example given the following fragment of HTML
|
||
*
|
||
*
|
||
* ```html
|
||
* <div ng-model-options="{ allowInvalid: true, debounce: 200 }">
|
||
* <form ng-model-options="{ updateOn: 'blur', "*": '$inherit' }">
|
||
* <input ng-model-options="{ updateOn: 'default', "*": '$inherit' }" />
|
||
* </form>
|
||
* </div>
|
||
* ```
|
||
*
|
||
* the `input` element will have the following settings
|
||
*
|
||
* ```js
|
||
* { allowInvalid: true, updateOn: 'default', debounce: 200 }
|
||
* ```
|
||
*
|
||
* Notice that the `debounce` setting now inherits the value from the outer `<div>` element.
|
||
*
|
||
* If you are creating a reusable component then you should be careful when using `"*": "$inherit"`
|
||
* since you may inadvertently inherit a setting in the future that changes the behavior of your component.
|
||
*
|
||
*
|
||
* ## Triggering and debouncing model updates
|
||
*
|
||
* The `updateOn` and `debounce` properties allow you to specify a custom list of events that will
|
||
* trigger a model update and/or a debouncing delay so that the actual update only takes place when
|
||
* a timer expires; this timer will be reset after another change takes place.
|
||
*
|
||
* Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
|
||
* be different from the value in the actual model. This means that if you update the model you
|
||
* should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in
|
||
* order to make sure it is synchronized with the model and that any debounced action is canceled.
|
||
*
|
||
* The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue}
|
||
* method is by making sure the input is placed inside a form that has a `name` attribute. This is
|
||
* important because `form` controllers are published to the related scope under the name in their
|
||
* `name` attribute.
|
||
*
|
||
* Any pending changes will take place immediately when an enclosing form is submitted via the
|
||
* `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
|
||
* to have access to the updated model.
|
||
*
|
||
* The following example shows how to override immediate updates. Changes on the inputs within the
|
||
* form will update the model only when the control loses focus (blur event). If `escape` key is
|
||
* pressed while the input field is focused, the value is reset to the value in the current model.

* $scope.user = { name: 'say' };
|
||
* }]);
|
||
* </file>
|
||
* </example>
|
||
*
|
||
* ## Model updates and validation
|
||
*
|
||
* The default behaviour in `ngModel` is that the model value is set to `undefined` when the
|
||
* validation determines that the value is invalid. By setting the `allowInvalid` property to true,
|
||
* the model will still be updated even if the value is invalid.
|
||
*
|
||
*
|
||
* ## Connecting to the scope
|
||
*
|
||
* By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression
|
||
* on the scope refers to a "getter/setter" function rather than the value itself.
|
||
*
|
||
* The following example shows how to bind to getter/setters:
|
||
*
|
||
* <example name="ngModelOptions-directive-getter-setter" module="getterSetterExample">

||
* <file name="index.html">

* ## Specifying timezones
|
||
*
|
||
* You can specify the timezone that date/time input directives expect by providing its name in the
|
||
* `timezone` property.
|
||
*
|
||
* @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and
|
||
* and its descendents. Valid keys are:
|
||
* - `updateOn`: string specifying which event should the input be bound to. You can set several
|
||
* events using an space delimited list. There is a special event called `default` that
|
||
* matches the default events belonging to the control.
|
||
* - `debounce`: integer value which contains the debounce model update value in milliseconds. A
|
||
* value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
|
||
* custom value for each event. For example:
|
||
* ```
|
||
* ng-model-options="{
|
||
* updateOn: 'default blur',
|
||
* debounce: { 'default': 500, 'blur': 0 }
|
||
* }"
|
||
* ```
|
||
* - `allowInvalid`: boolean value which indicates that the model can be set with values that did
|
||
* not validate correctly instead of the default behavior of setting the model to undefined.
|
||
* - `getterSetter`: boolean value which determines whether or not to treat functions bound to
|
||
* `ngModel` as getters/setters.
|
||
* - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
|
||
* `<input type="date" />`, `<input type="time" />`, ... . It understands UTC/GMT and the
|
||
* continental US time zone abbreviations, but for general use, use a time zone offset, for
|
||
* example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
|
||
* If not specified, the timezone of the browser will be used.

* @description
|
||
*
|
||
* The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
|
||
* elements for the `<select>` element using the array or object obtained by evaluating the
|
||
* `ngOptions` comprehension expression.
|
||
*
|
||
* In many cases, {@link ng.directive:ngRepeat ngRepeat} can be used on `<option>` elements instead of
|
||
* `ngOptions` to achieve a similar result. However, `ngOptions` provides some benefits:
|
||
* - more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
|
||
* comprehension expression
|
||
* - reduced memory consumption by not creating a new scope for each repeated instance
|
||
* - increased render speed by creating the options in a documentFragment instead of individually
|
||
*
|
||
* When an item in the `<select>` menu is selected, the array element or object property
|
||
* represented by the selected option will be bound to the model identified by the `ngModel`
|
||
* directive.
|
||
*
|
||
* Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
|
||
* be nested into the `<select>` element. This element will then represent the `null` or "not selected"
|
||
* option. See example below for demonstration.
|
||
*
|
||
* ## Complex Models (objects or collections)
|
||
*
|
||
* By default, `ngModel` watches the model by reference, not value. This is important to know when
|
||
* binding the select to a model that is an object or a collection.
|
||
*
|
||
* One issue occurs if you want to preselect an option. For example, if you set
|
||
* the model to an object that is equal to an object in your collection, `ngOptions` won't be able to set the selection,
|
||
* because the objects are not identical. So by default, you should always reference the item in your collection
|
||
* for preselections, e.g.: `$scope.selected = $scope.collection[3]`.
|
||
*
|
||
* Another solution is to use a `track by` clause, because then `ngOptions` will track the identity
|
||
* of the item not by reference, but by the result of the `track by` expression. For example, if your
|
||
* collection items have an id property, you would `track by item.id`.
|
||
*
|
||
* A different issue with objects or collections is that ngModel won't detect if an object property or
|
||
* a collection item changes. For that reason, `ngOptions` additionally watches the model using
|
||
* `$watchCollection`, when the expression contains a `track by` clause or the the select has the `multiple` attribute.
|
||
* This allows ngOptions to trigger a re-rendering of the options even if the actual object/collection
|
||
* has not changed identity, but only a property on the object or an item in the collection changes.
|
||
*
|
||
* Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection
|
||
* if the model is an array). This means that changing a property deeper than the first level inside the
|
||
* object/collection will not trigger a re-rendering.
|
||
*
|
||
* ## `select` **`as`**
|
||
*
|
||
* Using `select` **`as`** will bind the result of the `select` expression to the model, but
|
||
* the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)
|
||
* or property name (for object data sources) of the value within the collection. If a **`track by`** expression
|
||
* is used, the result of that expression will be set as the value of the `option` and `select` elements.
|
||
*
|
||
*
|
||
* ### `select` **`as`** and **`track by`**
|
||
*
|
||
* <div class="alert alert-warning">
|
||
* Be careful when using `select` **`as`** and **`track by`** in the same expression.
|
||
* </div>
|
||
*
|
||
* Given this array of items on the $scope:
|
||
*
|
||
* ```js
|
||
* $scope.items = [{
|
||
* id: 1,
|
||
* label: 'aLabel',
|
||
* subItem: { name: 'aSubItem' }
|
||
* }, {
|
||
* id: 2,
|
||
* label: 'bLabel',
|
||
* subItem: { name: 'bSubItem' }
|
||
* }];
|
||
* ```
|
||
*
|
||
* This will work:
|
||
*
|
||
* ```html
|
||
* <select ng-options="item as item.label for item in items track by item.id" ng-model="selected"></select>
|
||
* ```
|
||
* ```js
|
||
* $scope.selected = $scope.items[0];
|
||
* ```
|
||
*
|
||
* but this will not work:
|
||
*
|
||
* ```html
|
||
* <select ng-options="item.subItem as item.label for item in items track by item.id" ng-model="selected"></select>
|
||
* ```
|
||
* ```js
|
||
* $scope.selected = $scope.items[0].subItem;
|
||
* ```
|
||
*
|
||
* In both examples, the **`track by`** expression is applied successfully to each `item` in the
|
||
* `items` array. Because the selected option has been set programmatically in the controller, the
|
||
* **`track by`** expression is also applied to the `ngModel` value. In the first example, the
|
||
* `ngModel` value is `items[0]` and the **`track by`** expression evaluates to `items[0].id` with
|
||
* no issue. In the second example, the `ngModel` value is `items[0].subItem` and the **`track by`**
|
||
* expression evaluates to `items[0].subItem.id` (which is undefined). As a result, the model value
|
||
* is not matched against any `<option>` and the `<select>` appears as having no selected value.

||
* @param {string} ngModel Assignable AngularJS expression to data-bind to.

|
||
* * `label` **`disable when`** `disable` **`for (`**`key`**`,`** `value`**`) in`** `object`
|
||
* * `select` **`as`** `label` **`group by`** `group`

*
|
||
* Where:
|
||
*
|
||
* * `array` / `object`: an expression which evaluates to an array / object to iterate over.
|
||
* * `value`: local variable which will refer to each item in the `array` or each property value
|
||
* of `object` during iteration.
|
||
* * `key`: local variable which will refer to a property name in `object` during iteration.
|
||
* * `label`: The result of this expression will be the label for `<option>` element. The
|
||
* `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
|
||
* * `select`: The result of this expression will be bound to the model of the parent `<select>`
|
||
* element. If not specified, `select` expression will default to `value`.
|
||
* * `group`: The result of this expression will be used to group options using the `<optgroup>`
|
||
* DOM element.
|
||
* * `disable`: The result of this expression will be used to disable the rendered `<option>`
|
||
* element. Return `true` to disable.
|
||
* * `trackexpr`: Used when working with an array of objects. The result of this expression will be
|
||
* used to identify the objects in the array. The `trackexpr` will most likely refer to the
|
||
* `value` variable (e.g. `value.propertyName`). With this the selection is preserved
|
||
* even when the options are recreated (e.g. reloaded from the server).
|
||
* @param {string=} name Property name of the form under which the control is published.
|
||
* @param {string=} required The control is considered valid only if value is entered.
|
||
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
|
||
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
|
||
* `required` when you want to data-bind to the `required` attribute.
|
||
* @param {string=} ngAttrSize sets the size of the select element dynamically. Uses the
|
||
* {@link guide/interpolation#-ngattr-for-binding-to-arbitrary-attributes ngAttr} directive.

/**
|

* @ngdoc directive
|
||
* @name ngPluralize
|
||
* @restrict EA
|
||
*
|
||
* @description
|
||
* `ngPluralize` is a directive that displays messages according to en-US localization rules.
|
||
* These rules are bundled with angular.js, but can be overridden
|
||
* (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
|
||
* by specifying the mappings between
|
||
* [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
|
||
* and the strings to be displayed.
|
||
*
|
||
* # Plural categories and explicit number rules
|
||
* There are two
|
||
* [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
|
||
* in Angular's default en-US locale: "one" and "other".
|
||
*
|
||
* While a plural category may match many numbers (for example, in en-US locale, "other" can match
|
||
* any number that is not 1), an explicit number rule can only match one number. For example, the
|
||
* explicit number rule for "3" matches the number 3. There are examples of plural categories
|
||
* and explicit number rules throughout the rest of this documentation.
|
||
*
|
||
* # Configuring ngPluralize
|
||
* You configure ngPluralize by providing 2 attributes: `count` and `when`.
|
||
* You can also provide an optional attribute, `offset`.
|
||
*
|
||
* The value of the `count` attribute can be either a string or an {@link guide/expression
|
||
* Angular expression}; these are evaluated on the current scope for its bound value.
|
||
*
|
||
* The `when` attribute specifies the mappings between plural categories and the actual
|
||
* string to be displayed. The value of the attribute should be a JSON object.
|
||
*
|
||
* The following example shows how to configure ngPluralize:
|
||
*
|
||
* ```html
|
||
* <ng-pluralize count="personCount"
|
||
when="{'0': 'Nobody is viewing.',
|
||
* 'one': '1 person is viewing.',
|
||
* 'other': '{} people are viewing.'}">
|
||
* </ng-pluralize>
|
||
*```
|
||
*
|
||
* In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
|
||
* specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
|
||
* would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
|
||
* other numbers, for example 12, so that instead of showing "12 people are viewing", you can
|
||
* show "a dozen people are viewing".
|
||
*
|
||
* You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
|
||
* into pluralized strings. In the previous example, Angular will replace `{}` with
|
||
* <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
|
||
* for <span ng-non-bindable>{{numberExpression}}</span>.
|
||
*
|
||
* If no rule is defined for a category, then an empty string is displayed and a warning is generated.
|
||
* Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.
|
||
*
|
||
* # Configuring ngPluralize with offset
|
||
* The `offset` attribute allows further customization of pluralized text, which can result in
|
||
* a better user experience. For example, instead of the message "4 people are viewing this document",
|
||
* you might display "John, Kate and 2 others are viewing this document".
|
||
* The offset attribute allows you to offset a number by any desired value.
|
||
* Let's take a look at an example:
|
||
*
|
||
* ```html
|
||
* <ng-pluralize count="personCount" offset=2
|
||
* when="{'0': 'Nobody is viewing.',
|
||
* '1': '{{person1}} is viewing.',
|
||
* '2': '{{person1}} and {{person2}} are viewing.',
|
||
* 'one': '{{person1}}, {{person2}} and one other person are viewing.',
|
||
* 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
|
||
* </ng-pluralize>
|
||
* ```
|
||
*
|
||
* Notice that we are still using two plural categories(one, other), but we added
|
||
* three explicit number rules 0, 1 and 2.
|
||
* When one person, perhaps John, views the document, "John is viewing" will be shown.
|
||
* When three people view the document, no explicit number rule is found, so
|
||
* an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
|
||
* In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
|
||
* is shown.
|
||
*
|
||
* Note that when you specify offsets, you must provide explicit number rules for
|
||
* numbers from 0 up to and including the offset. If you use an offset of 3, for example,
|
||
* you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
|
||
* plural categories "one" and "other".
|
||
*
|
||
* @param {string|expression} count The variable to be bound to.
|
||
* @param {string} when The mapping between plural category to its corresponding strings.
|
||
* @param {number=} offset Offset to deduct from the total number.
|
||
*

|
||
* @description
|
||
* The `ngRepeat` directive instantiates a template once per item from a collection. Each template
|
||
* instance gets its own scope, where the given loop variable is set to the current collection item,
|
||
* and `$index` is set to the item index or key.
|
||
*
|
||
* Special properties are exposed on the local scope of each template instance, including:
|
||
*
|
||
* | Variable | Type | Details |
|
||
* |-----------|-----------------|-----------------------------------------------------------------------------|
|
||
* | `$index` | {@type number} | iterator offset of the repeated element (0..length-1) |
|
||
* | `$first` | {@type boolean} | true if the repeated element is first in the iterator. |
|
||
* | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
|
||
* | `$last` | {@type boolean} | true if the repeated element is last in the iterator. |
|
||
* | `$even` | {@type boolean} | true if the iterator position `$index` is even (otherwise false). |
|
||
* | `$odd` | {@type boolean} | true if the iterator position `$index` is odd (otherwise false). |
|
||
*
|
||
* <div class="alert alert-info">
|
||
* Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
|
||
* This may be useful when, for instance, nesting ngRepeats.

|

*
|
||
*
|
||
* # Iterating over object properties
|
||
*
|
||
* It is possible to get `ngRepeat` to iterate over the properties of an object using the following
|
||
* syntax:
|
||
*
|
||
* ```js
|
||
* <div ng-repeat="(key, value) in myObj"> ... </div>
|
||
* ```
|
||
*
|
||
* However, there are a few limitations compared to array iteration:
|
||
*
|
||
* - The JavaScript specification does not define the order of keys
|
||
* returned for an object, so Angular relies on the order returned by the browser
|
||
* when running `for key in myObj`. Browsers generally follow the strategy of providing
|
||
* keys in the order in which they were defined, although there are exceptions when keys are deleted
|
||
* and reinstated. See the
|
||
* [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
|
||
*
|
||
* - `ngRepeat` will silently *ignore* object keys starting with `$`, because
|
||
* it's a prefix used by Angular for public (`$`) and private (`$$`) properties.
|
||
*
|
||
* - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
|
||
* objects, and will throw an error if used with one.
|
||
*
|
||
* If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
|
||
* that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
|
||
* do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
|
||
* or implement a `$watch` on the object yourself.
|
||
*
|
||
*
|
||
* # Tracking and Duplicates
|
||
*
|
||
* `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
|
||
* the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM:
|
||
*
|
||
* * When an item is added, a new instance of the template is added to the DOM.
|
||
* * When an item is removed, its template instance is removed from the DOM.
|
||
* * When items are reordered, their respective templates are reordered in the DOM.
|
||
*
|
||
* To minimize creation of DOM elements, `ngRepeat` uses a function
|
||
* to "keep track" of all items in the collection and their corresponding DOM elements.
|
||
* For example, if an item is added to the collection, `ngRepeat` will know that all other items
|
||
* already have DOM elements, and will not re-render them.
|
||
*
|
||
* The default tracking function (which tracks items by their identity) does not allow
|
||
* duplicate items in arrays. This is because when there are duplicates, it is not possible
|
||
* to maintain a one-to-one mapping between collection items and DOM elements.
|
||
*
|
||
* If you do need to repeat duplicate items, you can substitute the default tracking behavior
|
||
* with your own using the `track by` expression.
|
||
*
|
||
* For example, you may track items by the index of each item in the collection, using the
|
||
* special scope property `$index`:
|
||
* ```html
|
||
* <div ng-repeat="n in [42, 42, 43, 43] track by $index">
|
||
* {{n}}
|
||
* </div>
|
||
* ```
|
||
*
|
||
* You may also use arbitrary expressions in `track by`, including references to custom functions
|
||
* on the scope:
|
||
* ```html
|
||
* <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)">
|
||
* {{n}}
|
||
* </div>
|
||
* ```
|
||
*
|
||
* <div class="alert alert-success">
|
||
* If you are working with objects that have a unique identifier property, you should track
|
||
* by this identifier instead of the object instance. Should you reload your data later, `ngRepeat`
|
||
* will not have to rebuild the DOM elements for items it has already rendered, even if the
|
||
* JavaScript objects in the collection have been substituted for new ones. For large collections,
|
||
* this significantly improves rendering performance. If you don't have a unique identifier,
|
||
* `track by $index` can also provide a performance boost.
|
||
* </div>
|
||
*
|
||
* ```html
|
||
* <div ng-repeat="model in collection track by model.id">
|
||
* {{model.name}}
|
||
* </div>
|
||
* ```
|
||
*
|
||
* <br />
|
||
* <div class="alert alert-warning">
|
||
* Avoid using `track by $index` when the repeated template contains
|
||
* {@link guide/expression#one-time-binding one-time bindings}. In such cases, the `nth` DOM
|
||
* element will always be matched with the `nth` item of the array, so the bindings on that element
|
||
* will not be updated even when the corresponding item changes, essentially causing the view to get
|
||
* out-of-sync with the underlying data.
|
||
* </div>
|
||
*
|
||
* When no `track by` expression is provided, it is equivalent to tracking by the built-in
|
||
* `$id` function, which tracks items by their identity:
|
||
* ```html
|
||
* <div ng-repeat="obj in collection track by $id(obj)">
|
||
* {{obj.prop}}
|
||
* </div>
|
||
* ```
|
||
*
|
||
* <br />
|
||
* <div class="alert alert-warning">
|
||
* **Note:** `track by` must always be the last expression:
|
||
* </div>
|
||
* ```
|
||
* <div ng-repeat="model in collection | orderBy: 'id' as filtered_result track by model.id">
|
||
* {{model.name}}
|
||
* </div>
|
||
* ```
|
||
*
|
||
*
|
||
* # Special repeat start and end points
|
||
* To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
|
||
* the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
|
||
* The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
|
||
* up to and including the ending HTML tag where **ng-repeat-end** is placed.
|
||
*
|
||
* The example below makes use of this feature:
|
||
* ```html
|
||
* <header ng-repeat-start="item in items">
|
||
* Header {{ item }}
|
||
* </header>
|
||
* <div class="body">
|
||
* Body {{ item }}
|
||
* </div>
|
||
* <footer ng-repeat-end>
|
||
* Footer {{ item }}
|
||
* </footer>
|
||
* ```
|
||
*
|
||
* And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
|
||
* ```html
|
||
* <header>
|
||
* Header A
|
||
* </header>
|
||
* <div class="body">
|
||
* Body A
|
||
* </div>
|
||
* <footer>
|
||
* Footer A
|
||
* </footer>
|
||
* <header>
|
||
* Header B
|
||
* </header>
|
||
* <div class="body">
|
||
* Body B
|
||
* </div>
|
||
* <footer>
|
||
* Footer B
|
||
* </footer>
|
||
* ```
|
||
*
|
||
* The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
|
||
* as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).

* @animations
|
||
* | Animation | Occurs |
|
||
* |----------------------------------|-------------------------------------|
|
||
* | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter |
|
||
* | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out |
|
||
* | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered |
|
||
*
|
||
* See the example below for defining CSS animations with ngRepeat.
|
||
*
|
||
* @element ANY
|
||
* @scope
|
||
* @priority 1000
|
||
* @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
|
||
* formats are currently supported:
|
||
*
|
||
* * `variable in expression` – where variable is the user defined loop variable and `expression`
|
||
* is a scope expression giving the collection to enumerate.
|
||
*
|
||
* For example: `album in artist.albums`.
|
||
*
|
||
* * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
|
||
* and `expression` is the scope expression giving the collection to enumerate.
|
||
*
|
||
* For example: `(name, age) in {'adam':10, 'amalie':12}`.
|
||
*
|
||
* * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
|
||
* which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
|
||
* is specified, ng-repeat associates elements by identity. It is an error to have
|
||
* more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
|
||
* mapped to the same DOM element, which is not possible.)
|
||
*
|
||
* Note that the tracking expression must come last, after any filters, and the alias expression.
|
||
*
|
||
* For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements
|
||
* will be associated by item identity in the array.
|
||
*
|
||
* For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
|
||
* `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
|
||
* with the corresponding item in the array by identity. Moving the same object in array would move the DOM
|
||
* element in the same way in the DOM.
|
||
*
|
||
* For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
|
||
* case the object identity does not matter. Two objects are considered equivalent as long as their `id`
|
||
* property is same.
|
||
*
|
||
* For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
|
||
* to items in conjunction with a tracking expression.
|
||
*
|
||
* * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
|
||
* intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
|
||
* when a filter is active on the repeater, but the filtered result set is empty.
|
||
*
|
||
* For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
|
||
* the items have been processed through the filter.
|
||
*
|
||
* Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end
|
||
* (and not as operator, inside an expression).
|
||
*
|
||
* For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` .
|
||
*
|
||
* @example
|
||
* This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
|
||
* results by name or by age. New (entering) and removed (leaving) items are animated.

/**
|
||
* @ngdoc directive
|
||
* @name ngShow
|
||
* @multiElement
|
||
*
|
||
* @description
|
||
* The `ngShow` directive shows or hides the given HTML element based on the expression provided to
|
||
* the `ngShow` attribute.
|
||
*
|
||
* The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
|
||
* The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
|
||
* `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
|
||
* {@link ng.directive:ngCsp ngCsp}).
|
||
*
|
||
* ```html
|
||
* <!-- when $scope.myValue is truthy (element is visible) -->
|
||
* <div ng-show="myValue"></div>
|
||
*
|
||
* <!-- when $scope.myValue is falsy (element is hidden) -->
|
||
* <div ng-show="myValue" class="ng-hide"></div>
|
||
* ```
|
||
*
|
||
* When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added
|
||
* to the class attribute on the element causing it to become hidden. When truthy, the `.ng-hide`
|
||
* CSS class is removed from the element causing the element not to appear hidden.
|
||
*
|
||
* ## Why is `!important` used?
|
||
*
|
||
* You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
|
||
* `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
|
||
* simple as changing the display style on a HTML list item would make hidden elements appear
|
||
* visible. This also becomes a bigger issue when dealing with CSS frameworks.
|
||
*
|
||
* By using `!important`, the show and hide behavior will work as expected despite any clash between
|
||
* CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
|
||
* developer chooses to override the styling to change how to hide an element then it is just a
|
||
* matter of using `!important` in their own CSS code.
|
||
*
|
||
* ### Overriding `.ng-hide`
|
||
*
|
||
* By default, the `.ng-hide` class will style the element with `display: none !important`. If you
|
||
* wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
|
||
* the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
|
||
* `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
|
||
*
|
||
* ```css
|
||
* .ng-hide:not(.ng-hide-animate) {
|
||
* /* These are just alternative ways of hiding an element */
|
||
* display: block!important;
|
||
* position: absolute;
|
||
* top: -9999px;
|
||
* left: -9999px;
|
||
* }
|
||
* ```
|
||
*
|
||
* By default you don't need to override anything in CSS and the animations will work around the
|
||
* display style.
|
||
*
|
||
* ## A note about animations with `ngShow`
|
||
*
|
||
* Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
|
||
* directive expression is true and false. This system works like the animation system present with
|
||
* `ngClass` except that you must also include the `!important` flag to override the display
|
||
* property so that the elements are not actually hidden during the animation.
|
||
*
|
||
* ```css
|
||
* /* A working example can be found at the bottom of this page. */
|
||
* .my-element.ng-hide-add, .my-element.ng-hide-remove {
|
||
* transition: all 0.5s linear;
|
||
* }
|
||
*
|
||
* .my-element.ng-hide-add { ... }
|
||
* .my-element.ng-hide-add.ng-hide-add-active { ... }
|
||
* .my-element.ng-hide-remove { ... }
|
||
* .my-element.ng-hide-remove.ng-hide-remove-active { ... }
|
||
* ```
|
||
*
|
||
* Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
|
||
* to block during animation states - ngAnimate will automatically handle the style toggling for you.

* By using `!important`, the show and hide behavior will work as expected despite any clash between
|
||
* CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
|
||
* developer chooses to override the styling to change how to hide an element then it is just a
|
||
* matter of using `!important` in their own CSS code.
|
||
*
|
||
* ### Overriding `.ng-hide`
|
||
*
|
||
* By default, the `.ng-hide` class will style the element with `display: none !important`. If you
|
||
* wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
|
||
* the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
|
||
* `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
|
||
*
|
||
* ```css
|
||
* .ng-hide:not(.ng-hide-animate) {
|
||
* /* These are just alternative ways of hiding an element */
|
||
* display: block!important;
|
||
* position: absolute;
|
||
* top: -9999px;
|
||
* left: -9999px;
|
||
* }
|
||
* ```
|
||
*
|
||
* By default you don't need to override in CSS anything and the animations will work around the
|
||
* display style.
|
||
*
|
||
* ## A note about animations with `ngHide`
|
||
*
|
||
* Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
|
||
* directive expression is true and false. This system works like the animation system present with
|
||
* `ngClass` except that you must also include the `!important` flag to override the display
|
||
* property so that the elements are not actually hidden during the animation.
|
||
*
|
||
* ```css
|
||
* /* A working example can be found at the bottom of this page. */
|
||
* .my-element.ng-hide-add, .my-element.ng-hide-remove {
|
||
* transition: all 0.5s linear;
|
||
* }
|
||
*
|
||
* .my-element.ng-hide-add { ... }
|
||
* .my-element.ng-hide-add.ng-hide-add-active { ... }
|
||
* .my-element.ng-hide-remove { ... }
|
||
* .my-element.ng-hide-remove.ng-hide-remove-active { ... }
|
||
* ```
|
||
*
|
||
* Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
|
||
* to block during animation states - ngAnimate will automatically handle the style toggling for you.

|

* @description
|
||
* The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
|
||
* Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
|
||
* as specified in the template.
|
||
*
|
||
* The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
|
||
* from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
|
||
* matches the value obtained from the evaluated expression. In other words, you define a container element
|
||
* (where you place the directive), place an expression on the **`on="..."` attribute**
|
||
* (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
|
||
* a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
|
||
* expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
|
||
* attribute is displayed.
|
||
*
|
||
* <div class="alert alert-info">
|
||
* Be aware that the attribute values to match against cannot be expressions. They are interpreted
|
||
* as literal string values to match against.
|
||
* For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
|
||
* value of the expression `$scope.someVal`.

* Directive that marks the insertion point for the transcluded DOM of the nearest parent directive that uses transclusion.
|

* You can specify that you want to insert a named transclusion slot, instead of the default slot, by providing the slot name
|

* as the value of the `ng-transclude` or `ng-transclude-slot` attribute.
|
||
*
|
||
* If the transcluded content is not empty (i.e. contains one or more DOM nodes, including whitespace text nodes), any existing
|
||
* content of this element will be removed before the transcluded content is inserted.
|
||
* If the transcluded content is empty (or only whitespace), the existing content is left intact. This lets you provide fallback
|
||
* content in the case that no transcluded content is provided.

|
||
*
|
||
* @description
|
||
* HTML `select` element with angular data-binding.
|
||
*
|
||
* The `select` directive is used together with {@link ngModel `ngModel`} to provide data-binding
|
||
* between the scope and the `<select>` control (including setting default values).
|
||
* It also handles dynamic `<option>` elements, which can be added using the {@link ngRepeat `ngRepeat}` or
|
||
* {@link ngOptions `ngOptions`} directives.
|
||
*
|
||
* When an item in the `<select>` menu is selected, the value of the selected option will be bound
|
||
* to the model identified by the `ngModel` directive. With static or repeated options, this is
|
||
* the content of the `value` attribute or the textContent of the `<option>`, if the value attribute is missing.
|
||
* Value and textContent can be interpolated.
|
||
*
|
||
* ## Matching model and option values
|
||
*
|
||
* In general, the match between the model and an option is evaluated by strictly comparing the model
|
||
* value against the value of the available options.
|
||
*
|
||
* If you are setting the option value with the option's `value` attribute, or textContent, the
|
||
* value will always be a `string` which means that the model value must also be a string.
|
||
* Otherwise the `select` directive cannot match them correctly.
|
||
*
|
||
* To bind the model to a non-string value, you can use one of the following strategies:
|
||
* - the {@link ng.ngOptions `ngOptions`} directive
|
||
* ({@link ng.select#using-select-with-ngoptions-and-setting-a-default-value})
|
||
* - the {@link ng.ngValue `ngValue`} directive, which allows arbitrary expressions to be
|
||
* option values ({@link ng.select#using-ngvalue-to-bind-the-model-to-an-array-of-objects Example})
|
||
* - model $parsers / $formatters to convert the string value
|
||
* ({@link ng.select#binding-select-to-a-non-string-value-via-ngmodel-parsing-formatting Example})
|
||
*
|
||
* If the viewValue of `ngModel` does not match any of the options, then the control
|
||
* will automatically add an "unknown" option, which it then removes when the mismatch is resolved.
|
||
*
|
||
* Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
|
||
* be nested into the `<select>` element. This element will then represent the `null` or "not selected"
|
||
* option. See example below for demonstration.
|
||
*
|
||
* ## Choosing between `ngRepeat` and `ngOptions`
|
||
*
|
||
* In many cases, `ngRepeat` can be used on `<option>` elements instead of {@link ng.directive:ngOptions
|
||
* ngOptions} to achieve a similar result. However, `ngOptions` provides some benefits:
|
||
* - more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
|
||
* comprehension expression
|
||
* - reduced memory consumption by not creating a new scope for each repeated instance
|
||
* - increased render speed by creating the options in a documentFragment instead of individually
|
||
*
|
||
* Specifically, select with repeated options slows down significantly starting at 2000 options in
|
||
* Chrome and Internet Explorer / Edge.
|
||
*
|
||
*
|
||
* @param {string} ngModel Assignable angular expression to data-bind to.
|
||
* @param {string=} name Property name of the form under which the control is published.
|
||
* @param {string=} multiple Allows multiple options to be selected. The selected values will be
|
||
* bound to the model as an array.
|
||
* @param {string=} required Sets `required` validation error key if the value is not entered.
|
||
* @param {string=} ngRequired Adds required attribute and required validation constraint to
|
||
* the element when the ngRequired expression evaluates to true. Use ngRequired instead of required
|
||
* when you want to data-bind to the required attribute.
|
||
* @param {string=} ngChange Angular expression to be executed when selected option(s) changes due to user
|
||
* interaction with the select element.
|
||
* @param {string=} ngOptions sets the options that the select is populated with and defines what is
|
||
* set on the model on selection. See {@link ngOptions `ngOptions`}.
|
||
* @param {string=} ngAttrSize sets the size of the select element dynamically. Uses the
|
||
* {@link guide/interpolation#-ngattr-for-binding-to-arbitrary-attributes ngAttr} directive.

|
||
* @description
|
||
*
|
||
* ngRequired adds the required {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.
|
||
* It is most often used for {@link input `input`} and {@link select `select`} controls, but can also be
|
||
* applied to custom controls.
|
||
*
|
||
* The directive sets the `required` attribute on the element if the Angular expression inside
|
||
* `ngRequired` evaluates to true. A special directive for setting `required` is necessary because we
|
||
* cannot use interpolation inside `required`. See the {@link guide/interpolation interpolation guide}
|
||
* for more info.
|
||
*
|
||
* The validator will set the `required` error key to true if the `required` attribute is set and
|
||
* calling {@link ngModel.NgModelController#$isEmpty `NgModelController.$isEmpty`} with the
|
||
* {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`} returns `true`. For example, the
|
||
* `$isEmpty()` implementation for `input[text]` checks the length of the `$viewValue`. When developing
|
||
* custom controls, `$isEmpty()` can be overwritten to account for a $viewValue that is not string-based.

|

* ngPattern adds the pattern {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.
|
||
* It is most often used for text-based {@link input `input`} controls, but can also be applied to custom text-based controls.
|
||
*
|
||
* The validator sets the `pattern` error key if the {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`}
|
||
* does not match a RegExp which is obtained by evaluating the Angular expression given in the
|
||
* `ngPattern` attribute value:
|
||
* * If the expression evaluates to a RegExp object, then this is used directly.
|
||
* * If the expression evaluates to a string, then it will be converted to a RegExp after wrapping it
|
||
* in `^` and `$` characters. For instance, `"abc"` will be converted to `new RegExp('^abc$')`.
|
||
*
|
||
* <div class="alert alert-info">
|
||
* **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
|

|
||
* account.
