Get the last part of an url in Javascript

Using the following URL example, how would I get the obtain the username from it?

http://www.mysite.com/username_here801

A regex solution would be cool.

The following sample only gets the domain name:

  var url = $(location).attr('href');

  alert(get_domain(url));

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

jQuery solutions are also acceptable.

var url = "http://www.mysite.com/username_here801";    
var username = url.match(/username_(.+)/)[1];

To always return the text directly after the slash that follows the .com you can do this:

var url = "http://www.mysite.com/username_here801";
var urlsplit = url.split("/");
var username = urlsplit[3];

You could use your getDomain() function to find out where your pathname start.:

function getUsername(url){
   var position = getDomain(url).length + 1;
   return url.slice(position); 
}

If a RegEx solution is acceptable, you could try:

function get_path(url) {
    // following regex extracts the path from URL
    return url.replace(/^https?:\/\/[^\/]+\//i, "").replace(/\/$/, "");
}

You can access it with document.location.pathname
