Question

Could someone recommend a way to get page name from a url using JavaScript?

For instance if I have:

http://www.cnn.com/news/1234/news.html?a=1&b=2&c=3

I just need to get “news.html” string

Thanks!

You can do this pretty easily via window.location.pathname parsing:

var file, n;

file = window.location.pathname;
n = file.lastIndexOf('/');
if (n >= 0) {
    file = file.substring(n + 1);
}
alert(file);

…or as others have said, you can do it with a regexp in one line. One kinda dense-looking line, but with a comment above it, should be a good way to go.
