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);
};
});
