I'm using JavaScript to try and get the filename from the URL.
I can get it using this:
var fn=window.location.href.match(/([^/])+/g);
alert(fn[fn.length-1]); // get the last element of the array
but is there an easier way to get it (e.g., without having to use fn[fn.length-1]
Thanks!!
Add a $ at the end so you only get the last part:
window.location.href.match(/[^/]+$/g);
Personally, I try to use simple string manipulation for easy tasks like this. It makes for more readable code (for a person not very familiar with RegEx).
var url = window.location.pathname;
var filename = url.substring(url.lastIndexOf('/')+1);
Or simply:
var filename = window.location.pathname.substring(window.location.pathname.lastIndexOf('/')+1);
Additional Information
Not that it matters for something so trivial, but this method is also more performant than RegEx: http://jsperf.com/get-file-name
How about:
window.location.href.match(/\/([^/]+)$/)[1];
you can use .pop() to get the last element of an array;
alert(fn.pop());
There is a jQuery plugin that makes it easy to parse URLs and provide access to their different parts. One of the things it does is return the filename. Here's the plugin on GitHub:

I would recommend using that and avoid reinventing the wheel. Regular expressions is an area of programming where this is particularly applicable.
