Retrieving JavaScript source file location?

Question

If I load a JavaScript source file like so:

<!DOCTYPE html>
<html>
    <head>
        <script src="src/file.js"></source>
    </head>
    <body>
    </body>
</html>

My question is that how could file.js know that the relative path to its location is src/? I need this information for building up a URL from the source file that depends on the URL it was loaded from.

<script src="src/file.js" id="script0"></script>

In file.js:

var path = document.getElementById ( "script0" ).getAttribute ( "src" );

I just thought about it myself too :). I'll just get all script elements, loop through them and use a simple regex replace to take the relative path (if the src matched).

If you use getAttribute you'll get the written src. If you use the .src attribute, you'll get the src with current location.
