onended 特性为 OscillatorNode interface is used to set the event handler for the ended event, which fires when the tone has stopped playing.

句法

范例

The following example shows basic usage of an AudioContext to create an oscillator node. For an applied example, check out our Violent Theremin demo ( see app.js for relevant code).

// create web audio api context
var audioCtx = new (window.AudioContext || window.webkitAudioContext)();
// create Oscillator node
var oscillator = audioCtx.createOscillator();
oscillator.type = 'square';
oscillator.frequency.value = 440; // value in hertz
oscillator.start(); // start the tone playing
oscillator.stop(5); // the tone will stop again in 5 seconds.
oscillator.onended = function() {
  console.log('Your tone has now stopped playing!');
}
