Here's a function that can get the querystring variables in JS for you:

function $_GET(q){
    var $_GET = {};
    if(document.location.toString().indexOf('?') !== -1){
        var query = document.location
                       .toString()
                       .replace(/^.*?\?/, '')//Get the query string
                       .replace(/#.*$/, '')//and remove any existing hash string
                       .split('&');
        for(var i=0, l=query.length; i<l; i++){
           var aux = decodeURIComponent(query[i]).split('=');
           $_GET[aux[0]] = aux[1];
        }
    }
    return $_GET[q];
}

Does this help at all?
