Question

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];
