Retrieving JavaScript source file location?

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.

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

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

In file.js:

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