RTCDataChannelEvent: RTCDataChannelEvent() constructor

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The RTCDataChannelEvent() constructor creates a new RTCDataChannelEvent object.

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

Syntax

js
new RTCDataChannelEvent(type, options)

Parameters

type

A string with the name of the event. It is case-sensitive and browsers always set it to datachannel.

options

An object that, in addition of the properties defined in Event(), can have the following properties:

channel

A RTCDataChannel, representing the data channel being associated with the event.

Return value

A new RTCDataChannelEvent object configured as specified.

Example

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

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