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 RTCPeerConnection.ondatachannel
property is an EventHandler
which specifies a function which is called when the datachannel
event occurs on an RTCPeerConnection
. This event, of type RTCDataChannelEvent
, is sent when an RTCDataChannel
is added to the connection by the remote peer calling createDataChannel()
.
At the time this event is received, the RTCDataChannel
it indicates may not yet actually be open. Be sure to wait for the "open"
event to be fired on the new RTCDataChannel
before using it.
Syntax
RTCPeerConnection.ondatachannel = function;
Value
Set this property to be a function you provide which receives as input a single parameter: an RTCDataChannelEvent
which provides in its channel
property the RTCDataChannel
which has been created.
Example
pc.ondatachannel = function(ev) { console.log('Data channel is created!'); ev.channel.onopen = function() { console.log('Data channel is open and ready to be used.'); }; };
