Revision Content

A PresentationConnectionClosedEvent is fired when a presentation connection enters a closed state. The reason attribute provides the reason why the connection was closed.

Property

error
means that the mechanism for connecting or communicating with a presentation entered an unrecoverable error.
closed
means that either the controlling browsing context or the receiving browsing context that were connected by the PresentationConnection called close().
wentaway
means that the browser closed the connection, for example, because the browsing context that owned the connection navigated or was discarded.

When the reason attribute is error, the user agent SHOULD set the error message to a human readable description of how the communication channel encountered an error.
