How to get the file-path of the currently executing javascript code

Question

I\'m trying to do something like a C #include \"filename.c\", or PHP include(dirname(__FILE__).\"filename.php\") but in javascript. I know I can do

Answer 1

All browsers except Internet Explorer (any version) have document.currentScript, which always works always (no matter how the file was included (async, bookmarklet etc)).

If you want to know the full URL of the JS file you're in right now:

var script = document.currentScript;
var fullUrl = script.src;

Tadaa.
