Question

I’m pretty sure the answer is no, but thought I’d ask anyway.

If my site references a scripted named ‘whatever.js’, is it possible to get ‘whatever.js’ from within that script? Like:

var scriptName = ???  if (typeof jQuery !== 'function') {     throw new Error(         'jQuery's script needs to be loaded before ' +          scriptName + '. Check the <script> tag order.'); } 

Probably more trouble than it’s worth for dependency checking, but what the hell.

Answer 1

var scripts = document.getElementsByTagName('script'); var lastScript = scripts[scripts.length-1]; var scriptName = lastScript.src; alert("loading: " + scriptName); 

Tested in: FF 3.0.8, Chrome 1.0.154.53, IE6
