The read-only property RTCPeerConnection.pendingRemoteDescription 返回 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 .

句法

sessionDescription = RTCPeerConnection.pendingRemoteDescription;
					

返回值

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

范例

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
}

见实现注意事项。

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