Get the last part of an url in Javascript
<p>Using the following URL example, how would I get the obtain the username from it?</p>

<p><a href="http://www.mysite.com/username_here801" rel="nofollow">http://www.mysite.com/username_here801</a></p>

<p>A regex solution would be cool.</p>

<p>The following sample only gets the domain name:</p>

<pre><code>  var url = $(location).attr('href');

  alert(get_domain(url));

  function get_domain(url) {
    return url.match(/http:\/\/.*?\//);
  }
</code></pre>

<p>jQuery solutions are also acceptable.</p>
