RTCDataChannelEvent.channel

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

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;
}
