How to pass parameters to a Script tag?

Question

I read the tutorial DIY widgets - How to embed your site on another site for XSS Widgets by Dr. Nic.

I'm looking for a way to pass parameters to the script tag. For example, to make the following work:

<script src="http://path/to/widget.js?param_a=1&amp;param_b=3"></script> 

Is there a way to do this?

Answer 1

I apologise for replying to a super old question but after spending an hour wrestling with the above solutions I opted for simpler stuff.

<script src=".." one="1" two="2"></script> 

Inside above script:

document.currentScript.getAttribute('one'); //1 document.currentScript.getAttribute('two'); //2 

Much easier than jquery OR url parsing.

You might need the polyfil for doucment.currentScript from @Yared Rodriguez's answer for IE:

document.currentScript = document.currentScript || (function() {   var scripts = document.getElementsByTagName('script');   return scripts[scripts.length - 1]; })();
