parsing url with javascript or jquery

Question

I have a url in this form http://www.example.com/data/45. How do I get the last element (45 in this example) using jQuery or JavaScript?

Thanks.

Answer 1

A very quick plain JavaScript method, assuming it's the URL of the current page (in window.location.href)

var urlNum = window.location.href.split('/').pop();

.split('/') obviously chops the URL up into an array, based on divisions by /. Since you only need the last part, it is probably the easiest method.

.pop() removes the last element from the array returned by .split() and returns it.

Answer 2

var num = 'http://www.example.com/data/45'.split('/').pop(); //num now == '45'

Answer 3

My rendition :)

var url         = 'http://www.example.com/data/45';
var lastSegment = url.substr(url.lastIndexOf('/') + 1);
