JavaScript get last URL segment

What is the best way to get the Last segment of the URL (omitting any parameters). Also url may or may not include the last '/' character

for example

http://Home/Billing/Index.html?param1=2&another=2
should result in: Index.html

http://Home/Billing/Index.html/
should result in: Index.html

I've tried this but i can't get how to check for the last /

ar href = window.location.pathname;
            var value = href.lastIndexOf('/') + 1);

@psantiago answer works great. If you want to do the same but using RegEx you can implement as follows:

var r = /(\/([A-Za-z0-9\.]+)(\??|\/?|$))+/;
r.exec("http://Home/Billing/Index.html?param1=2&another=2")[2]; //outputs: Index.html 
r.exec("http://Home/Billing/Index.html/"); //outputs: Index.html

In my opinion, the above code is more efficient and cleaner than using split operations.

Maybe something like?

window.location.pathname.split('?')[0].split('/').filter(function (i) { return i !== ""}).slice(-1)[0]
  1. Split on '?' to throw out any query string parameters
  2. Get the first of those splits
  3. Split on '/'.
  4. For all those splits, filter away all the empty strings
  5. Get the last one remaining
