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

Question

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

Example YouTube URL formats

http://www.youtube.c

Answer 1

One more:

var id = url.match(/(^|=|\/)([0-9A-Za-z_-]{11})(\/|&|$|\?|#)/)[2]

It works with any URL showed in this thread.

It won't work when YouTube addS some other parameter with 11 base64 characters. Till then it is the easy way.
