How to pass parameters to a Script tag?

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'); //1document.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];})();

It's better to Use feature in html5 5 data Attributes

<script src="http://path.to/widget.js" data-width="200" data-height="200"></script>

Inside the script file http://path.to/widget.js you can get the paremeters in that way:

<script>function getSyncScriptParams() {         var scripts = document.getElementsByTagName('script');         var lastScript = scripts[scripts.length-1];         var scriptName = lastScript;         return {             width : scriptName.getAttribute('data-width'),             height : scriptName.getAttribute('data-height')         }; }</script>

Got it. Kind of a hack, but it works pretty nice:

var params = document.body.getElementsByTagName('script');query = params[0].classList;var param_a = query[0];var param_b = query[1];var param_c = query[2];

I pass the params in the script tag as classes:

<script src="http://path.to/widget.js" class="2 5 4"></script>
