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
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.
let output = midiAccess.outputs.get(portID);
output.close(); // closes the port
