An signalingstatechange event is sent to an RTCPeerConnection to notify it that its signaling state, as indicated by the signalingState property, has changed.

范例

Given an RTCPeerConnection , pc , and an updateStatus() function that presents status information to the user, this code sets up an event handler to let the user know when the ICE negotiation process finishes up.

pc.addEventListener("signalingstatechange", ev => {
  switch(pc.signalingState) {
    case "stable":
      updateStatus("ICE negotiation complete");
      break;
  }
}, false);

使用 onsignalingstatechange , it looks like this:

pc.onsignalingstatechange = ev => {
  switch(pc.signalingState) {
    case "stable":
      updateStatus("ICE negotiation complete");
      break;
    }
};
