JQuery.Validation - ＆gt;使用AjaxSubmit的SubmitHandler事件不是函数错误

Question

您好我正在尝试在JQuery.Validation的submitHandler中调用我的控制器/动作MVC并且它不能在那里工作，我可以使它工作在cshtml中的事件submitHandler之外创建$ ajax工作，但为什么这里不起作用？我收到一个错误：ajaxSubmit不是firebug中的函数。为什么？感谢

var form = $('.handlevalidation');
    var error = $('.alert-danger', form);
    var success = $('.alert-success', form);

    form.validate({
        errorElement: 'span', //default input error message container
        errorClass: 'help-block help-block-error', // default input error message class
        focusInvalid: false, // do not focus the last invalid input
        ignore: "", // validate all fields including form hidden input
        messages: {
            'Employee.Username': { remote: "This Username was already taken." },
            'Employee.Barcode': { remote: "This Barcode is already in use." }
        },
        rules: {

            // ** RULES **
            'Employee.Username': {
                minlength: 3,
                maxlength: 55,
                required: true,
                remote: { url: baseUrl + 'Employees/CheckDuplicatedUsername', type: "post", data: { username: function () { return $('#Employee_Username').val(); }, id: function () { return $('#Employee_Id').val(); } } }
            },

            'Employee.Password': { minlength: 3, maxlength: 55, required: false },
            'Employee.Barcode': {
                maxlength: 255,
                required: false,
                remote: { url: baseUrl + 'Employees/CheckDuplicatedBarcode', type: "post", data: { barcode: function () { return $('#Employee_Barcode').val(); }, id: function () { return $('#Employee_Id').val(); } } }
            },

            'Employee.FirstName': { minlength: 3, maxlength: 55, required: true },
            'Employee.LastName': { minlength: 3, maxlength: 55, required: false },
            'Employee.EmailAddress': { required: false, email: true },

            'Password': { required: true, minlength: 3, maxlength: 10 },
            'ConfirmPassword': { required: true, minlength: 3, maxlength: 10, equalTo: "#Password" }
        },

        invalidHandler: function (event, validator) { //display error alert on form submit              
            success.hide();
            error.show();
            Metronic.scrollTo(error, -200);
        },

        highlight: function (element) { // hightlight error inputs
            $(element)
                .closest('.form-group').addClass('has-error'); // set error class to the control group
        },

        unhighlight: function (element) { // revert the change done by hightlight
            $(element)
                .closest('.form-group').removeClass('has-error'); // set error class to the control group
        },

        success: function (label) {
            label
                .closest('.form-group').removeClass('has-error'); // set success class to the control group
        },

        submitHandler: function (form) {
            success.show();
            error.hide();


            $form.ajaxSubmit({
                type: 'post',
                url: baseUrl + 'Employees/UpdatePassword',
                data: $form.serialize(),

                success: function (response) {

                    if (response == 'success') {

                        var $target = $($form.attr('data-target'));
                        alert('Password changed successfully!');

                        $target.modal('hide');

                    } else {
                        error.show();
                    }
                }
            });
        }
    });
