Canvas client functions

[beta] This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features. 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.
