RTCPeerConnection.pendingLocalDescription

The read-only property RTCPeerConnection.pendingLocalDescription returns an RTCSessionDescription object describing a pending configuration change for the local 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.currentLocalDescription or RTCPeerConnection.localDescription to get the current state of the endpoint. For details on the difference, see Pending and current descriptions in WebRTC connectivity.

Syntax

sessionDescription = RTCPeerConnection.pendingLocalDescription;

Return value

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

Example

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

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