RTCDataChannelEvent() 构造函数创建新 RTCDataChannelEvent .

You will rarely if ever construct an RTCDataChannelEvent by hand; these events are normally created and sent by the WebRTC layer itself.

 var event = new RTCDataChannelEvent(type, rtcDataChannelEventInit);

type


									DOMString

which specifies the name of the event. There is only one type of


								RTCDataChannelEvent

, so this will always be


								"datachannel"

rtcDataChannelEventInit


								RTCDataChannelEventInit

dictionary, which has following fields:

"channel" 类型 RTCDataChannel , representing the data channel being concerned by the event.
"bubbles" , optional, inherited from EventInit . Indicates if the event must bubble or not. 默认为 false .
"cancelable" , optional, inherited from EventInit . Indicates if the event can be canceled or not. Default is false.

新的 RTCDataChannelEvent configured as specified.

In this example, a new datachannel event is created. dc is a data channel which already exists.

var event = new RTCDataChannelEvent("datachannel", {"channel": dc});
