MIDIPort: close() method
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 close() method of the MIDIPort interface makes the access to the MIDI device connected to this MIDIPort unavailable.
If the port is successfully closed a new MIDIConnectionEvent is queued to the MIDIPort statechange and MIDIAccess statechange events, and the MIDIPort.connection property is changed to "closed".
Syntax
js
close()
Parameters
None.
Return value
Returns a Promise which resolves once the port has been closed.
Examples
The following example shows an output port being closed.
js
let output = midiAccess.outputs.get(portID);
output.close(); // closes the port
