OfflineAudioContext: complete event - Web APIs 编辑

The complete event of the OfflineAudioContext interface is fired when the rendering of an offline audio context is complete.

Examples

When processing is complete, you might want to use the oncomplete handler the prompt the user that the audio can now be played, and enable the play button:

let offlineAudioCtx = new OfflineAudioContext();

offlineAudioCtx.addEventListener('complete', () => {
  console.log('Offline audio processing now complete');
  showModalDialog('Song processed and ready to play');
  playBtn.disabled = false;
})

You can also set up the event handler using the OfflineAudioContext.oncomplete property:

let offlineAudioCtx = new OfflineAudioContext();

offlineAudioCtx.oncomplete = function() {
  console.log('Offline audio processing now complete');
  showModalDialog('Song processed and ready to play');
  playBtn.disabled = false;
}
