Question

我正在检查播放器的playerVars中的enablejsapi = 1选项为here 但这不起作用。我创建了一个plnkr here

这是我的HTML：

<!DOCTYPE html>

// 1. The <iframe> (and video player) will replace this <div> tag.
<div id="player"></div>

<script>
  // 2. 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);

  // 3. This function creates an <iframe> (and YouTube player)
  //    after the API code downloads.
  var player;
  function onYouTubeIframeAPIReady() {
    player = new YT.Player('player', {
      height: '390',
      width: '640',
      videoId: 'M7lc1UVf-VE',
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      },
      playerVars: {
        enablejsapi: 0,
        controls: 0
      }
    });
  }

  // 4. The API will call this function when the video player is ready.
  function onPlayerReady(event) {
    event.target.playVideo();
  }

  // 5. The API calls this function when the player's state changes.
  //    The function indicates that when playing a video (state=1),
  //    the player should play for six seconds and then stop.
  var done = false;
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.PLAYING && !done) {
      setTimeout(stopVideo, 6000);
      done = true;
    }
  }
  function stopVideo() {
    player.stopVideo();
  }
</script>

我只是将playerVars放在构造函数中，其余代码与iframe api reference

中给出的相同

默认情况下，文档链接表示值为0，但生成的iframe如下所示：

<iframe id="player" frameborder="0" allowfullscreen="1" title="YouTube video player" width="640" height="390" src="https://www.youtube.com/embed/M7lc1UVf-VE?enablejsapi=1&amp;controls=0&amp;widget_referrer=https%3A%2F%2Frun.plnkr.co%2Fpreview.html&amp;origin=https%3A%2F%2Frun.plnkr.co&amp;widgetid=1"></iframe>

因为我们可以看到enablejsapi设置为1，尽管我在playerVars中将其设置为0。 controls参数初始化为0。

那么为什么会这样呢？

我建议youtube iframe api团队调查它（报告SO，因为他们说他们按照https://developers.google.com/youtube/players/support跟踪问题）

Youtube iframe api enablejsapi在playerVars
