Calling WebService using JQuery not working in all browsers but only in IE9?
===

I have this code in a js file which I am including in Default page to Create cookies at the clients' browser and using it in the Thankyou page to invoke my web service to track payment transactions.



`// Read a page's GET URL variables and return them as an associative array.`

`$(document).ready(function () {`

    $.extend({
        getUrlVars: function () {
            var vars = [], hash;
            var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
            for (var i = 0; i < hashes.length; i++) {
                hash = hashes[i].split('=');
                vars.push(hash[0]);
                vars[hash[0]] = hash[1];
            }
            return vars;
        },
        getUrlVar: function (name) {
            return $.getUrlVars()[name];
        },
        getCookie: function (name) {
            var dc = document.cookie;
            var prefix = name + "=";
            var begin = dc.indexOf("; " + prefix);
            if (begin == -1) {
                begin = dc.indexOf(prefix);
                if (begin != 0) return null;
            }
            else {
                begin += 2;
                var end = document.cookie.indexOf(";", begin);
                if (end == -1) {
                    end = dc.length;
                }
            }
            return unescape(dc.substring(begin + prefix.length, end));
        }
    });


    {
        var cookieStart, cookieEnd, cookieValue, UserGuid, productId, AffiliationURL, PricePerUnit, commissionAmount;

        // Get object of URL parameters
        if ($.getUrlVars() != null) {
            var allVars = $.getUrlVars();
        }

        // Getting URL var by its name

        //Now check if the user is from Seek Site??
        //If this is not null that means the user is Refered from Seek Site
        if ($.getUrlVar('clientId') != null) {

            UserGuid = $.getUrlVar('clientId');

            if ($.getUrlVar('productId') != null) {
                productId = $.getUrlVar('productId');
            }
            if ($.getUrlVar('AffiliationURL') != null) {
                AffiliationURL = $.getUrlVar('AffiliationURL');
            }
            if ($.getUrlVar('PricePerUnit') != null) {
                PricePerUnit = $.getUrlVar('PricePerUnit');
            }
            if ($.getUrlVar('commissionAmount') != null) {
                commissionAmount = $.getUrlVar('commissionAmount');
            }


            //Now Create the cookie for the user
            var myCookie = $.getCookie("ReferedCookie");
            alert(myCookie);
            if (myCookie != null) {
                // cookie exists 
                cookieStart = myCookie.indexOf("clientId=");
                //alert(cookieStart = cookieStart + "ReferedCookie=".length);
                cookieEnd = myCookie.indexOf(";", cookieStart);

                //if there is no occurence of the semicolon character 
                //cookieEnd takes the length of the   document.cookie property
                if (cookieEnd == -1) cookieEnd = myCookie.length;

                cookieValue = myCookie.substring(cookieStart, cookieEnd);



                // check the Product Id
                if (cookieValue.indexOf(productId + "&", "productId=") != -1) {
                    // that means the User clicked on the same Product again and there is already a cookie Exists for that product
                    alert("User clicked on the same Product again");
                }

                else {
                    // The Product Id is different ,We are going to add that product value as string to the  cookie 

                }
            }

            else {
                // Create Cookie
                var expiryDate = new Date();
                expiryDate.setTime(expiryDate.setDate(expiryDate.getDate() + 365)); // 365 days

                document.cookie = "ReferedCookie=" + "clientId=" + UserGuid + "&productId=" + productId + "&AffiliationURL=" + AffiliationURL + "&PricePerUnit=" + PricePerUnit + "&commissionAmount=" + commissionAmount + ";" + "expires=" + expiryDate.toGMTString() + ";";

            }

        }
    }});




And Here the Code which I want to run at Thankyou page but it runs in IE9 (at time I dnt know why???)


    {
    var cookieStart, cookieEnd, cookieValue, UserGuid, productId, AffiliationURL, PricePerUnit, commissionAmount;
    $(window).load(function (e) {
        e.preventDefault();
        $.extend({
            readCookie: function (name) {
                var nameEQ = name + "=";
                var ca = document.cookie.split(';');
                for (var i = 0; i < ca.length; i++) {
                    var c = ca[i];
                    while (c.charAt(0) == ' ') c = c.substring(1, c.length);
                    if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
                }
                return null;
            }
        });

        var x = new Array(3);

        cookieValue = $.readCookie("ReferedCookie");

        var s = 0;
        var pos = cookieValue.indexOf("&");
        while (pos > -1) {
            x[s] = pos;
            pos = cookieValue.indexOf("&", pos + 1);
            // alert(x[s]);
            s++;
        }

        var c1 = cookieValue.indexOf("clientId=");
        alert(UserGuid = cookieValue.substring(c1 + 9, x[0]));

        var p1 = cookieValue.indexOf("productId=");
        alert(productId = cookieValue.substring(p1 + 10, x[1]));

        var A1 = cookieValue.indexOf("AffiliationURL=");
        alert(AffiliationURL = cookieValue.substring(A1 + 15, x[2]));

        var pp1 = cookieValue.indexOf("PricePerUnit=");
        alert(PricePerUnit = cookieValue.substring(pp1 + 13, x[3]));

        var com1 = cookieValue.indexOf("commissionAmount=");
        alert(commissionAmount = cookieValue.substring(com1 + 17));


        var ServiceURL = 'http://localhost:12445/Service/TrackPayment.asmx/InsertCommissionRecord';
       // var d = '{"ProductID": "' + productId + '" , "AffiliationURL": "' + AffiliationURL + '" , "Quantitiy": "' + 15 + '" , "PricePerUnit": "' + PricePerUnit + '" , "commissionAmount": "' + commissionAmount + '"}';
        var d = '{"ProductID":"1","AffiliationURL":"1","Quantitiy":"1","PricePerUnit":"1","commissionAmount":"1"}';
        alert(d);
        $.ajax({
            type: 'POST',
            data: d,
            url: ServiceURL,
            contentType: 'application/json; charset=utf-8',
            dataType: 'json',
            success:
              function (data, textStatus, XMLHttpRequest) {
                  alert(data);
                  alert(textStatus);

                  alert(XMLHttpRequest);
              },
            error:
              function (XMLHttpRequest, textStatus, errorThrown) {
                  alert(textStatus);
                  alert(errorThrown);
              }
        });
    });}


In firebug console it show data.d is null

Kindly help me out and please point out where I am going wrong.
Thanks
