在火狐下，前面的代码都有走到，但是一到ajax的时候，里面的data就无效了

$(function () {
        $('#btn_Submit').on('click', function () {
            var isLogined = '@(!AccountUtility.IsBrokerLogin)';
            var s = $("#RecordContent").html();
            $("#Contents").val(s);
            var $cVal=$("#Contents").val();
            var re = $cVal.replace(/ /g,"");
            if (isLogined.toLowerCase() == 'true') {
                ToastErrorV2("请登录账号！");
                window.event.returnValue = false;
                setTimeout(function() {
                    window.location.href = "@(companyDomain)/Account/BrokerLogin?returnUrl=@(xyfmDomain)@Url.Action("Details", "ForumList", new { number = vm.Number })";
                }, 3000);
            }
            else if ($.trim(re) == "" || $.trim(re) == "<br>") {
                setTimeout(function () { }, 3000);
                ToastErrorV2('请填写评论内容！');
                return false;
            }
            else {
                $.Jq_Ajax.post({
                    url: '@(Url.Action("Comment", "ForumList"))',
                    data: $("#form1").serializeArray(),
                    form: $("#form1"),
                    onSuccess: function (data) {
                        //window.location.reload();
                    }
                });
            }
        });
