RTCDataChannelEvent: channel property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The read-only property RTCDataChannelEvent.channel
returns the RTCDataChannel
associated with the event.
Value
A RTCDataChannel
object representing the data channel linking the
receiving RTCPeerConnection
to its remote peer.
Example
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.
js
pc.ondatachannel = (event) => {
inboundDataChannel = event.channel;
inboundDataChannel.onmessage = handleIncomingMessage;
inboundDataChannel.onopen = handleChannelOpen;
inboundDataChannel.onclose = handleChannelClose;
};
