例子

js
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:

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