=== Canvas client functions
|
|
|
|
beta[]These functions must execute in a browser. They are only available
|
|
from within the Canvas application, not via the Canvas HTTP API. These functions must
|
|
execute in the browser because they use browser specific APIs, such as location,
|
|
or interact with the workpad to read filters.

A *** denotes a required argument.
