RTCIceTransport: statechange event
A statechange
event occurs when the RTCIceTransport
changes state. The state
can be used to determine how far through the process of examining, verifying, and selecting a valid candidate pair is prior to successfully connecting the two peers for WebRTC communications.
This event is not cancelable and does not bubble.
Syntax
Use the event name in methods like addEventListener()
, or set an event handler property.
addEventListener('statechange', event => { });
onstatechange = event => { };
Event type
A generic Event
.
Examples
Given an RTCPeerConnection
, pc
, the following code creates an event handler that calls a function named handleFailure()
if the ICE transport enters a failure state.
let iceTransport = pc.getSenders()[0].transport.iceTransport;
iceTransport.addEventListener("statechange", ev => {
if (iceTransport.state === "failed") {
handleFailure(pc);
}
}, false);
The same code, using the onstatechange
event handler property, looks like this:
let iceTransport = pc.getSenders()[0].transport.iceTransport;
iceTransport.onstatechange = ev => {
if (iceTransport.state === "failed") {
handleFailure(pc);
}
};
