例子

处理完成后，您可能希望使用oncomplete处理程序提示用户现在可以播放音频，并启用播放按钮：

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 {{domxref("OfflineAudioContext.oncomplete")}} property:

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