This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

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});
