Handling Orientation Changes in Your Canvas App

The orientation event enables you to handle changes in orientation when your canvas app appears on a mobile device. After your canvas app subscribes to the event, the event fires whenever the parent window fires a window.orientation event. The event returns a payload that contains these values.

orientationContains one of these values.
  • 0: landscape to portrait
