This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use 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 spec changes.
The RTCDataChannel.onopen
event handler is a property called when the open
event is received. Such an event is sent when a the underlying data transport, that is the data connection, has been established.
On Gecko, the interface this property belongs to is called DataChannel
instead of RTCDataChannel.
