javascript - 控制Bxslider中的youtube视频自动播放并在播放完毕后滑动到下一张幻灯片

Question

我正在尝试在 iframe 中控制 youtube 视频。视频位于 Bxslider结构。我将 slider 设置为自动启动，其中包含 iframe 视频。

我想做的是，当“currentSlide”是视频幻灯片时，自动播放它并在视频结束后“转到下一张幻灯片”。因此，请卡住幻灯片直至视频完成。

我已经尝试过，但它只在第一次加载时起作用，当 slider 返回到第一张幻灯片时，视频和 slider 本身都不再自动播放/卡住。问题是没有错误消息..

让它工作，请参阅此 CodePen

我更改了以下内容:

 function onPlayerStateChange(event) {
  console.log('play Status::::::::' + event.data);
  if (event.data == YT.PlayerState.ENDED && !done) {

/*~~~~~~~~~~~~~~~~~~~~~~~~~删除~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~

** var start = document.getElementsByClassName('bx-start');

** 开始[0].click();

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~*/

//ADD   bx.stopAuto();
        console.log('slider-started');
      } else if (event.data == YT.PlayerState.PLAYING) {

/*~~~~~~~~~~~~~~~~~~~~~~~~~删除~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~

** var stop = document.getElementsByClassName('bx-stop');

** 停止[0].click();

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~*/

//ADD   bx.startAuto();
        console.log('slider-stopped');
      } else if (event.data == YT.PlayerState.CUED) {
        event.target.playVideo();
        console.log('come here cued');
      }
    }
