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 read-only property RTCDataChannelEvent.channel returns the RTCDataChannel associated with the event.


 var channel = RTCDataChannelEvent.channel;


A RTCDataChannel object representing the data channel linking the receiving RTCPeerConnection to its remote peer.


The first line of code in the datachannel event handler shown below takes the channel from the event object and saves it locally for use by the code handling data traffic.

pc.ondatachannel = function(event) {
  inboundDataChannel = event.channel;
  inboundDataChannel.onmessage = handleIncomingMessage;
  inboundDataChannel.onopen = handleChannelOpen;
  inboundDataChannel.onclose = handleChannelClose;
