如何使用JavaScript获取视频标签src？ [英] How to get video tag src using JavaScript?

问题描述

我正在尝试使用JavaScript获取视频网址。
代码是......

 < div class =flideo> 
< video x-webkit-airplay =allowpreload =src =http://pdl.vimeocdn.com/80388/120/224743790.mp4?token2=1394169786_c1f036dda110a70d45fd824ec6692b94&amp;aksessionid=e766a96a167c751e poster =>< / video> 
< / div> 
  

谢谢..

解决方案

  var vids = document.getElementsByTagName（'video'）
 // vids是一个HTMLCollection 
 for（var i = 0; i< ; vids.length; i ++）{
 console.log（vids.item（i）.src）
} 
  

似乎对我有用！注意，这会变成HTMLCollection。 .length 给出长度， item（i）给出 i 。

  var vids = document.getElementsByTagName（'video'）/ / vids是HTMLCollectionfor（var i = 0; i< vids.length; i ++）{console.log（vids.item（i）.src）}  

< pre class =snippet-code-html lang-html prettyprint-override> < div class =flideo> < video x-webkit-airplay =allowpreload =src =http://pdl.vimeocdn.com/80388/120/224743790.mp4?token2=1394169786_c1f036dda110a70d45fd824ec6692b94&amp;aksessionid=e766a96a167c751eposter = >< / video>< / div>

I am trying to get video URL using JavaScript. Code is ...

<div class="flideo">
    <video x-webkit-airplay="allow" preload="" src="http://pdl.vimeocdn.com/80388/120/224743790.mp4?token2=1394169786_c1f036dda110a70d45fd824ec6692b94&amp;aksessionid=e766a96a167c751e" poster=""></video>
</div>

Thanks..

解决方案

var vids = document.getElementsByTagName('video') 
// vids is an HTMLCollection
for( var i = 0; i < vids.length; i++ ){ 
    console.log( vids.item(i).src )
}

Seems to work for me! Note, that turns an HTMLCollection. .length gives the length and item(i) gives the item at i.

var vids = document.getElementsByTagName('video') 
// vids is an HTMLCollection
for( var i = 0; i < vids.length; i++ ){ 
    console.log( vids.item(i).src )
}

<div class="flideo">
    <video x-webkit-airplay="allow" preload="" src="http://pdl.vimeocdn.com/80388/120/224743790.mp4?token2=1394169786_c1f036dda110a70d45fd824ec6692b94&amp;aksessionid=e766a96a167c751e" poster=""></video>
</div>
