Simple Javascript and Regexp solution

I produce my url to inpout from other site with this syntax: [login to view URL] Everything works perfect. When i hav this link: [login to view URL] (T&T)&customer_code=1234&username=bertha OR [login to view URL](T&t)&customer_code=12%20(1&2%20)34&username=bertha(%201%20&%20B) It doesnt work so fine. It the Regexp thats not working so fine. Have this code to make this happen: ---------------------------------------- "use strict"; (function() { /* Ändra här: */ var urlBind = { COMPANY_NAME: 'q1' ,CUSTOMER_CODE: 'q2' ,USERNAME: 'q3' }; jQuery(function() { for (var s in urlBind) { var uval = getParameterByName(s); if (uval) { $PX(urlBind[s]).value(uval); } } }) function getParameterByName(name, url) { if (!url) url = [login to view URL]; name = [login to view URL](/[\[\]]/g, "\\$&"); var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)", "i"), results = [login to view URL](url); if (!results) return null; if (!results[2]) return ''; return decodeURIComponent(results[2].replace(/\+/g, " ")); } })(); ---------------------------------
