The RTCDataChannel.onclosing property is an event handler which specifies a function to be called by the browser when the closing event is received by the RTCDataChannel. This is a simple Event which indicates that the data channel is being closed, that is, RTCDataChannel transitions to "closing" state. For example, after RTCDataChannel.close() was called but the underlying data transport might not have been closed yet.


RTCDataChannel.onclosing = function;


A function which the browser will call to handle the closing event. The function receives as its sole input parameter the event itself, as an object of type Event.
