当 FlexSlider 幻灯片不在视图中时停止播放 YouTube 视频

Question

我正在尝试将一些 YouTube 嵌入式视频放入 FlexSlider 轮播/滑块中。我遇到的问题是如果看不到幻灯片，则停止播放视频。目前，如果您播放视频和 select 一个新视频，则上一个视频会继续播放。

预期：切换幻灯片时，停止视频。实际：在更换幻灯片时，视频继续播放。

JS:

$(window).load(function() {  
  $('#carousel').flexslider({
    animation: "slide",
    controlNav: false,
    animationLoop: false,
    slideshow: false,
    itemWidth: 210,
    itemMargin: 5,
    asNavFor: '#slider'
  }); 
  $('#slider').flexslider({
    animation: "slide",
    controlNav: false,
    animationLoop: false,
    slideshow: false,
    sync: "#carousel"
  });
});

我这里有一个代码笔YouTube FlexSlider Carousel | Codepen

有什么想法可以实现吗？

谢谢

求助，加上一些js搞定了

$(window).load(function() {  
  $('#carousel').flexslider({
    animation: "slide",
    controlNav: false,
    animationLoop: false,
    slideshow: false,
    itemWidth: 210,
    itemMargin: 5,
    asNavFor: '#slider',
    start: function() {
      $('#carousel li').on('click', function(e){
        stopVideos();
      });
      $('#carousel li').on('click', function(e){
        stopVideos();
      });
    }
  }); 
  $('#slider').flexslider({
    animation: "slide",
    controlNav: false,
    animationLoop: false,
    slideshow: false,
    sync: "#carousel",
    start: function() {
      $('.flex-next').on('click', function(e){
        stopVideos();
      });
      $('.flex-prev').on('click', function(e){
        stopVideos();
      });
    }
  });
});

function stopVideos() {
  $('.iframe-vid').each(function() {
  this.contentWindow.postMessage('{"event":"command","func":"pauseVideo","args":""}', '*')
  });
}
