RTCPeerConnection.pendingRemoteDescription - Web APIs 编辑

The read-only property RTCPeerConnection.pendingRemoteDescription returns an RTCSessionDescription object describing a pending configuration change for the remote end of the connection. This does not describe the connection as it currently stands, but as it may exist in the near future. Use RTCPeerConnection.currentRemoteDescription or RTCPeerConnection.remoteDescription to get the current session description for the remote endpoint. For details on the difference, see Pending and current descriptions in WebRTC connectivity.

Syntax

sessionDescription = RTCPeerConnection.pendingRemoteDescription;

Return value

If a remote description change is in progress, this is an RTCSessionDescription describing the proposed configuration. Otherwise, this returns null.

Example

This example looks at the pendingRemoteDescription to determine whether or not there's a description change being processed.

var pc = new RTCPeerConnection();
…
var sd = pc.pendingRemoteDescription;
if (sd) {
  // There's a description change underway!
}
else {
  // No description change pending
}

Browser compatibility

BCD tables only load in the browser

The addition of pendingRemoteDescription and currentRemoteDescription to the WebRTC spec is relatively recent. In browsers which don't support them, only remoteDescription is available.
