Facebook广告:如何创建像素自定义Javascript事件来检测Youtube视频的点击

Question

假设我们有Youtube嵌入的代码：

<iframe id="my-youtube-video-id" width="560" height="315" src="https://www.youtube.com/embed/tzbrKBv-khE" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

和Facebook像素事件代码：

<button id="addToCartButton">Purchase</button>
<script type="text/javascript">
$('#$my-youtube-video-id').click(function() {
fbq('track', 'ViewContent');
});
</script>

但当有人点击视频时，它似乎并不能检测到。我上WordPress了。你知道我做错了什么吗？

我认为这不是Facebook Events的问题，而是iFrame的问题。托管在iFrame中的url接收单击事件，并且不会将该事件冒泡到iFrame元素本身。幸运的是，对于youtube视频，您可以使用嵌入式播放器API来执行基于播放器状态的操作。试试这个：

<iframe id="my-youtube-video-id" width="560" height="315" src="https://www.youtube.com/embed/tzbrKBv-khE?enablejsapi=1" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

<script>
  // This code loads the IFrame Player API code asynchronously.
  var tag = document.createElement('script');

  tag.src = "https://www.youtube.com/iframe_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

    var player;
    function onYouTubeIframeAPIReady() {
      player = new YT.Player('my-youtube-video-id', {
        events: {
          'onStateChange': onPlayerStateChange
        }
      });
    }

    var done;
    function onPlayerStateChange(event){
      if (event.data == YT.PlayerState.PLAYING && !done) {
        //Here is where you can add your event, we also use the done variable to make sure the event will only fire once.
        fbq('track', 'ViewContent');
        done = true;
      }
    }

  </script>

log to console when the onPlayerStateChange() function is called：查看这个将编辑的jsFiddle
