<iframe id="spkj" src="//player.bilibili.com/player.html?aid=886677146&bvid=BV12K4y1n74k&cid=297648780&page=1"
 width="100%" frameborder="no" scrolling="no" allowfullscreen="allowfullscreen">
<span data-mce-type="bookmark" style="display: inline-block; width: 0px; 
overflow: hidden; line-height: 0;" class="mce_SELRES_start"></span>
 </iframe> 
<script type="text/javascript"> document.getElementById("spkj").style.height=document.getElementById("spkj").scrollWidth*0.76+"px"; </script>

找到第一行的src="//player.bilibili.com/player.html?aid=886677146&bvid=BV12K4y1n74k&cid=297648780&page=1"

 复制b站的嵌入代码：

<iframe src="//player.bilibili.com/player.html?aid=756280384&bvid=BV17r4y1M7uV&cid=288463691&page=1" scrolling="no" border="0" frameborder="no" framespacing="0" allowfullscreen="true"> </iframe>

将b站这段代码中的src="//player.bilibili.com/player.html?aid=756280384&bvid=BV17r4y1M7uV&cid=288463691&page=1" 替换到上面第一行的代码中即可。
