Getting the current script executing file name in javascript

Question

Okay, I've been searching for this for way too long already... I'm trying to find out how I can return the filename of the page that's running an included javascript, from inside that javascript.

I can easily do this in PHP using $_SERVER['SCRIPT_FILENAME'], but in Javascript this seems to be a lot harder.

Do I really need to substring it from location.href or is there a more efficient way?

Answer 1

var url=location.href;
return url.substring(url.lastIndexOf('/')+1)
