MIDIConnectionEvent: MIDIConnectionEvent() constructor

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The MIDIConnectionEvent() constructor creates a new MIDIConnectionEvent object. Typically this constructor is not used as events are created when a new port becomes available, and the object is passed to the statechange event.

Syntax

js
new MIDIConnectionEvent(type)
new MIDIConnectionEvent(type, midiConnectionEventInit)

Parameters

type

A string with one of "connect" or "disconnect".

midiConnectionEventInit Optional

A dictionary including the following fields:

port

The MIDIPort instance representing the port that has connected or disconnected.

bubbles Optional

A boolean value indicating whether the event bubbles. The default is false.

cancelable Optional

A boolean value indicating whether the event can be cancelled. The default is false.

composed Optional

A boolean value indicating whether the event will trigger listeners outside of a shadow root (see Event.composed for more details). The default is false.
