MIDIConnectionEvent: port property

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 port read-only property of the MIDIConnectionEvent interface returns the port that has been disconnected or connected.

Value

A MIDIPort object.

Examples

The Navigator.requestMIDIAccess() method returns a promise that resolves with a MIDIAccess object. When a port changes state, a MIDIConnectionEvent is passed to the statechange event. Information about the port can then be printed to the console.

js
navigator.requestMIDIAccess().then((access) => {
  access.onstatechange = (event) => {
    console.log(event.port.name, event.port.manufacturer, event.port.state);
  };
});
