javascript - 发生视频广告跳过按钮事件时，焦点无法转移到 iframe 游戏

Question

我的网站有一些视频广告。视频广告显示后（发生 ima.adevent.type.complete），游戏通过以下代码获得键盘焦点。但是，如果通过单击跳过按钮跳过视频广告，则不会正确地为游戏提供焦点，这意味着 google.ima.AdEvent.Type.SKIPPED 的情况发生在下面的代码中。

case google.ima.AdEvent.Type.SKIPPED:
  case google.ima.AdEvent.Type.COMPLETE:
  // This event indicates the ad has finished - the video player
  // can perform appropriate UI actions, such as removing the timer for
  // remaining time detection.
  if (ad.isLinear()) {
    clearInterval(intervalTimer);
  }
  focusWhenReady = function () {
    doc = iframe.contentDocument || iframe.contentWindow.document;
    if (doc.readyState == "complete") {
      iframe.contentWindow.focus();
      console.log('code comes here in both cases ...');
    } else {
      setTimeout(focusWhenReady, 200)
    }
  }
  setTimeout(focusWhenReady, 100);
