URL of current script in JavaScript

Question

How can I find out the URL of the JS file that was called?

Let's say the JS file (which is part of a library) and the HTML file (which is the application) are on a different server. To find out the URL of the HTML file is easy. But how can I find out the server name and path of the JS files' server within the JS file itself? (Edit: There is a loader which invokes other JS files of thsi library in the same directory structure)

Preferably a JQuery or pure JS solution.

Edit:

After I learned from your answers and comments I decided it would be cleaner to actually move the loader code to the first server, where also the html lives, which avoids the problem.

Answer 1

In JQuery you could do:

$('script').each(function(i, e) {
    alert($(e).attr('src'));
});
