Check the Browser compatibility table carefully before using this in production.

The RTCDataChannelEvent() constructor creates a new RTCDataChannelEvent.

You will rarely if ever construct an RTCDataChannelEvent by hand; these events are normally created and sent by the WebRTC layer itself.


 var event = new RTCDataChannelEvent(type, rtcDataChannelEventInit);


A DOMString which specifies the name of the event. There is only one type of RTCDataChannelEvent, so this will always be "datachannel".
A RTCDataChannelEventInit dictionary, which has following fields:
  • "channel" of type RTCDataChannel, representing the data channel being concerned by the event.
  • "bubbles", optional, inherited from EventInit. Indicates if the event must bubble or not. Default is false.
  • "cancelable", optional, inherited from EventInit. Indicates if the event can be canceled or not. Default is false.


A new RTCDataChannelEvent configured as specified.


In this example, a new datachannel event is created. dc is a data channel which already exists.

var event = new RTCDataChannelEvent("datachannel", {"channel": dc});
