How do I get the YouTube video ID from a URL?

I made an enhancement to Regex provided by "jeffreypriebe" because he needed a kind of YouTube URL is the URL of the videos when they are looking through a channel.

Well no but this is the function that I have armed.

<script type="text/javascript">function youtube_parser(url){    var regExp = /^.*((youtu.be\/)|(v\/)|(\/u\/\w\/)|(embed\/)|(watch\?))\??v?=?([^#&?]*).*/;    var match = url.match(regExp);    return (match&&match[7].length==11)? match[7] : false;}</script>

These are the types of URLs supported

I simplified Lasnv's answer a bit.

It also fixes the bug that WebDeb describes.

Here it is:

var regExp = /^.*(youtu\.be\/|v\/|u\/\w\/|embed\/|watch\?v=|\&v=)([^#\&\?]*).*/;var match = url.match(regExp);if (match && match[2].length == 11) {  return match[2];} else {  //error}

Here is a regexer link to play with: http://regexr.com/3dnqv

You don't need to use a regular expression for this.

var video_id = window.location.search.split('v=')[1];var ampersandPosition = video_id.indexOf('&');if(ampersandPosition != -1) {  video_id = video_id.substring(0, ampersandPosition);}
