page	Card Refresh Plugin

The card refresh plugin provides the functionality for loading ajax content into the card.

Usage

This plugin can be activated as a jQuery plugin or using the data API.

Data API

{: .text-bold }

Activate the plugin by adding a button with data-card-widget="card-refresh" to the card and provide the required data-source="/URL-TO-CONTENT" option. By doing that, the plugin will automatically create a GET request to the provided URL and render the returned response the .card-body section of the card. If you need to process the returned response before rendering, you should use the jQuery API, which provides hooks to deal with the response.

jQuery

{: .text-bold }

The jQuery API provides more customizable options that allows the developer to pre-process the request before rendering and post-process it after rendering.

$('#my-card [data-card-widget="card-refresh"]').CardRefresh(options)
