Question

div与视频最初是隐藏的(与display: none;)，但iframe似乎加载得很好，按下一个按钮，我首先将display: none;更改为display: block;，然后做播放器(这是yt播放器的实例)player.playVideo()，没有什么不寻常的，真的。但是它会抛出这个错误。

注销player.playVideo确实返回undefined。

记录player，返回这个

{

      "b":{

         "height":709,

      {

         "args":[
            "onStateChange"
         ]
      }
   ],
   "g":{
      "a":[
         null,
         "onReady",
         null,
         null,
         "onStateChange",
         null,
         null
      ],
      "b":{
         "onReady":[
            1
         ],
         "onStateChange":[
            4
         ]
      },
      "G":7
   },
   "h":"player",
   "D":{
      "onReady":true,
      "onStateChange":true
   },
   "k":{
   },
   "i":{
   }
}

它适用于所有浏览器，但ie，我该怎么办?

Answer 1

原因确实很简单，因为div最初是隐藏的，您所需要做的就是以其他方式隐藏它，我在visibility: hidden;或opacity: 0;上没有真正取得多大成功，top: -alot;以及父overflow: hidden;完成了这项工作。

这段来自Harry Roberts的代码可能也可以完成这项工作。

/**
 * Hide content off-screen without resorting to `display:none;`, also provide
 * breakpoint specific hidden elements.
 */
@mixin accessibility{
    border:0!important;
    clip:rect(0 0 0 0)!important;
    height:1px!important;
    margin:-1px!important;
    overflow:hidden!important;
    padding:0!important;
    position: absolute!important;
    width:1px!important;
}
