Simple javascript parser edit for script

Budget is $10. I need to add to the script below, so that the url will be parsed and and the proper parameter value added to the script. Then after the parameter values have been added I would like the script to fire. For fbDE_email, an email should be pulled from url For fbDE_name, first and last name should be pulled from url Here is an example of the url query: ?thrivecart%5Baccount_id%5D=35345345725&thrivecart%5Baccount_name%5D=dcdfsdf&thrivecart%5Bcustomer%5D%5Bemail%5D=testemail%40yahoo.com&thrivecart%5Bcustomer%5D%5Bfirstname%5D=fsdf&thrivecart%5Bcustomer%5D%5Blastname%5D=fdsfsd This should work on desktop and mobile and should be compatible with all browsers. Here is the code: <script src="[login to view URL]"></script> <script> [login to view URL] = function(){ var fdDE_detail = { "fbDE_name":'thrivecart[customer][firstname] + thrivecart%5Bcustomer%5D%5Blastname%5D ', "fbDE_email":'thrivecart[customer][email]', "fbDE_vacation":1, "fbDE_business": '1321224' } fbDEBusiness(fdDE_detail); } </script>
