jquery getting GET variables from javascript file

问题

I have a link, and when a user clicks it, it pushes a javascript file onto the page. in addition to that, it adds on parameters to the javascript src example:

<script type="text/javascript" src="javascripfile.js?r=some%values&u=more&values">

This isn't getting passed through URL on browser. I was wondering how I would get these parameters inside javascriptfile.js?

javascriptfile.js:

(function(){
     //how to get r value, u value?
}());

Thanks for your help!

further in case you wondering about val.indexOf("?") + 1 why +1 it is to avid ?

This should help, :)

code

$("script").each(function(){
   if ($(this).prop('src').split("?")[0].indexOf("javascripfile.js") )
          value = $(this).prop("src");
});

var returnStr = value.substr(value.indexOf("?") +1);

alert(" value after ? is ==> " + returnStr);

var spliMe = returnStr.split('&');

alert("value of R ==> " + spliMe[0]);

OR

    var value = $(".foo").prop("src");

    var returnStr = value.substr(value.indexOf("?") +1);

    alert(" value after ? is ==> " + returnStr);

    var spliMe = returnStr.split('&');

tag

<script type="text/javascript" class="foo" src="javascripfile.js?r=some%values&u=more&values">
