Try looking at this post here: How can I get query string values in JavaScript?

First you will need to get an array of the parameters passed, which can be done via:

var newArray = window.location.search.substr(1).split('&')

try calling a blank function on pageLoad that then reads this. The array is then created by reading the param string window.location.search.substr(1) and then splits everything into an array seperated by the & field.

So if you had mysite.com/page.html?a=3&b=4 it would create an array with

newArray(0) = "a=3" and newArray(1) = "b=4"

then

var a = newArray(0).substring(2)
var b = newArray(1).substring(2)

the substring(2) will removed the "a=" and "b=" from the parameter and leave you with your end results for the parameters passed.

This should help you start.
