onstatechange event handler for the RTCIceTransport interface is a property which specifies a function to serve as the EventHandler 为 statechange event that is fired whenever the transport's state 改变。

句法

RTCIceTransport.onstatechange = stateChangeHandler;
					

值

Set this property to reference a function you provide that is called by the WebRTC layer when the RTCIceTransport 对象的 state 改变。

The event handler receives as its sole input an 事件 object describing the statechange event which occurred. To determine the new state, examine the value of state .

范例

This snippet establishes a handler for the statechange event that looks to see if the transport has entered the "failed" state, which indicates that the connection has failed with no chance of being automatically restored.

var iceTransport = pc.getSenders()[0].transport.iceTransport;
iceTransport.onstatechange = function(event) {
  if (iceTransport.state == "failed") {
    handleFailure(pc);
  }
}
