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 RTCPeerConnection.onsignalingstatechange
event handler is a property containing the code to execute whent the signalingstatechange
event, of type Event
, is received by this RTCPeerConnection
. Such an event is sent when the value of RTCPeerConnection.signalingState
changes, as the result of a call of RTCCPeerConnection.setLocalDescription()
or RTCPeerConnection.setRemoteDescription()
.
Syntax
peerconnection.onsignalingstatechange = function;
Values
function
is the name of a user-defined function, without the()
suffix or any parameters, or an anonymous function declaration, such asfunction(event) {...}
. An event handler always has one single parameter, containing the event, here of typeEvent
.
Example
pc.onsignalingstatechange = function(ev) { console.log("onsignalingstatechange event detected!"); };

[1] Though this property is not prefixed, the interface it belongs to is.
[2] Before Firefox 36, the event handler was passed the signaling state value instead of the event as required by the specification. This has been fixed.
