How to extract the filename of the URL of the current document path in JavaScript?

I'm trying to extract the current file name in Javascript without any parameters.

$(location).attr('href').match(/([a-zA-Z-_0-9]+.w+)$/);

var current_path = RegExp.$1;

if ((current_path == 'index.html') || ...) {

  // something here

}

But it doesn't work at all when you access like http://example.com/index.html?lang=ja. Sure before the file name will be changed at random.

Any idea?

If you're looking for the last item in the path, try this:

var current_path = window.location.pathname.split('/').pop();

This:

window.location.pathname

will give you something like:

/questions/6543242/how-to-extract-the-filename-of-url-in-javascript

Then the .split() will split the string into an Array, and .pop() will give you the last item in the Array.
