JQuery / Javascript HTTP POST无法在IE或Firefox中运行

Question

我正在努力让我的HTTP Post在Firefox和IE中运行，

它目前在Chrome中运行良好。

这是我目前的代码：

 $(function () {
        $('.scPracticeTest').on('click', function (e) {
            var guid = jQuery.Guid.New();
            var testcode = $(this).attr('testcode');
            $.support.cors = true;
            $.ajax({
                type : 'POST',
                url: 'https://sc-practice.content.saville.int/sites/api/Integration/SavilleLegacy/CreateCandidate.ashx',
                contentType: 'application/x-www-form-urlencoded',
                data: {
                    clientid: "4D102B05-8949-4B04-A87A-59AC5A88FC65",
                    username: "practiceintegration",
                    password: "practiceintegration",
                    givenname: guid,
                    familyname: guid,
                    culturecode: "en-GB"},
                success: function (data) {
                    candidate = $(data).find("accessid").text();
                    window.location.replace("https://sc-practice.content.saville.int/sites/api/Integration/SavilleLegacy/Assessment.ashx?clientid=4D102B05-8949-4B04-A87A-59AC5A88FC65&username=practiceintegration&password=practiceintegration&accessid=" + candidate + "&testcode=" + testcode + "&returnurl=https://www.savilleconsulting.com/products/test-aptitude-preparation-guides-and-advice/");
                    },
                    error: function (data) {
                        alert(data.statusText);
                    }
            })

        })
    });

我也有Jquery Guid链接 -

jQuery.extend({
    Guid: {
        Set: function (val) {
            var value;
            if (arguments.length == 1) {
                if (this.IsValid(arguments[0])) {
                    value = arguments[0];
                } else {
                    value = this.Empty();
                }
            }
            $(this).data("value", value);
            return value;
        },

        Empty: function () {
            return "00000000-0000-0000-0000-000000000000";
        },

        IsEmpty: function (gid) {
            return gid == this.Empty() || typeof (gid) == 'undefined' || gid == null || gid == '';
        },

        IsValid: function (value) {
            rGx = new RegExp("\\b(?:[A-F0-9]{8})(?:-[A-F0-9]{4}){3}-(?:[A-F0-9]{12})\\b");
            return rGx.exec(value) != null;
        },

        New: function () {
            if (arguments.length == 1 && this.IsValid(arguments[0])) {
                $(this).data("value", arguments[0]);
                value = arguments[0];
                return value;
            }

            var res = [], hv;
            var rgx = new RegExp("[2345]");
            for (var i = 0; i < 8; i++) {
                hv = (((1 + Math.random()) * 0x10000) | 0).toString(16).substring(1);
                if (rgx.exec(i.toString()) != null) {
                    if (i == 3) { hv = "6" + hv.substr(1, 3); }
                    res.push("-");
                }
                res.push(hv.toUpperCase());
            }
            value = res.join('');
            $(this).data("value", value);
            return value;
        },

        Value: function () {
            if ($(this).data("value")) {
                return $(this).data("value");
            }
            var val = this.New();
            $(this).data("value", val);
            return val;
        }
    }
})();`

任何想法都将是一个巨大的帮助！
