title: Strip URL to get YouTube ID
body: <p>I have:</p>
  
  <pre><code>var post = $('.post');
  post.find('.video embed').each(function(){
      v = $(this);
      youtubeID = v.attr('src').replace(/^.*youtube.com.*(?:\/|v=)(\w+)\//g,"");
      console.log(youtubeID);
  })
  </code></pre>
  
  <p>Here's an example URL taken from the embed src</p>
  
  <p><code>http://www.youtube.com/v/_eeZnLX_XBM&amp;rel=0&amp;egm=0&amp;showinfo=0&amp;fs=1</code></p>
  
  <p>It strips the everything up to <code>/v/</code> but not the ampersand and everything after that.</p>
  
  <p>I want <code>_eeZnLX_XBM</code> only.</p>
