How to get part of the path with jQuery?

var url = "www.webiste.com/Services/allservices.html"
    url = url.split("/");
    alert(url[1]);

In the above example split the string url when find / (separator) and save it in an array. Then using the proper index, you can use the substring you wish (in the above example will alert Services).
