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

<pre class="brush: js"><font><font>offlineAudioCtx.addEventListener('complete',()=&gt; {</font></font>
  console.log('Offline audio processing now complete');
  showModalDialog('Song processed and ready to play');
  playBtn.disabled = false;
})</pre>

<p>You can also set up the event handler using the {{domxref("OfflineAudioContext.oncomplete")}} property:</p>

<pre class="brush: js">offlineAudioCtx.oncomplete = function() {
  console.log('Offline audio processing now complete');
  showModalDialog('Song processed and ready to play');
  playBtn.disabled = false;
}</pre>
