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

by

I want to get the v=id from YouTube’s URL with JavaScript (no jQuery, pure JavaScript).

Example YouTube URL formats

http://www.youtube.com/watch?v=u8nQa1cJyX8&a=GxdCwVVULXctT2lYDEPllDR0LRTutYfW

http://www.youtube.com/watch?v=u8nQa1cJyX8

Or any other YouTube format that contains a video ID in the URL.

Result from these formats

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
