The read-only property RTCDataChannelEvent .channel 返回 RTCDataChannel 与事件关联。

句法

 var channel = RTCDataChannelEvent.channel;
					

值

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

范例

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;
}
