RTCDataChannelEvent

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 returns a new RTCDataChannelEvent object, which represents a datachannel event. These events sent to an RTCPeerConnection when its remote peer is asking to open an RTCDataChannel between the two peers.

You will rarely if ever construct an RTCDataChannelEvent by hand; instead, the WebRTC layer will generate and deliver them to you at the appropriate time. Just listen for the datachannel event and when you receive it, use the RTCDataChannelEvent.channel property to gain access to the data channel which has been opened.

Examples

In this example, the datachannel event handler is set up to save the data channel reference and set up handlers for the events which need to be monitored. The channel property provides the RTCDataChannel representing the connection to the other peer.

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

See A simple RTCDataChannel sample for another, more complete, example of how to use data channels.
