ExceptionEvent

The OT class dispatches exception events when the Vonage Video API encounters an exception (error). The ExceptionEvent object defines the properties of the event object that is dispatched.

Note that you set up a callback for the exception event by calling the OT.on() method.

Methods

isDefaultPrevented() → {Boolean}

Whether the default event behavior has been prevented via a call to preventDefault() (true) or not (false). See preventDefault().

Returns:

preventDefault()

Prevents the default behavior associated with the event from taking place.

To see whether an event has a default behavior, check the cancelable property of the event object.

Call the preventDefault() method in the callback function for the event.

The following events have default behaviors:

• sessionDisconnect — See SessionDisconnectEvent.preventDefault().
• streamDestroyed — See StreamEvent.preventDefault().
• accessDialogOpened — See the accessDialogOpened event.
• accessDenied — See the accessDenied event.
