RTCPeerConnection.connectionState - Web APIs 编辑

The read-only connectionState property of the RTCPeerConnection interface indicates the current state of the peer connection by returning one of the string values specified by the enum RTCPeerConnectionState.

When this property's value changes, a connectionstatechange event is sent to the RTCPeerConnection instance.

Syntax

var connectionState = RTCPeerConnection.connectionState;

Value

The current state of the connection, as a value from the enum RTCPeerConnectionState.

RTCPeerConnectionState enum

The RTCPeerConnectionState enum defines string constants which describe states in which the RTCPeerConnection may be. These values are returned by the connectionState property. This state essentially represents the aggregate state of all ICE transports (which are of type RTCIceTransport or RTCDtlsTransport) being used by the connection.

Example

var pc = new RTCPeerConnection(configuration);

/* ... */

var connectionState = pc.connectionState;
