发布不受支持

Question

我正在使用jquery验证插件验证表单。验证成功后，ajax调用正在db中插入数据。但这里显示帖子不受支持。

$("#evaluatorForm").validate({
// Specify the validation rules
rules: {
    employeeId: "required",
    name: "required",
    lastname: "required",
    email: {
        required: true,
        email: true
    },
    mobile:"required",
    bg:"required",
    bu:"required",

// Specify the validation error messages
messages: {
    name: "Please enter your first name",
    lastname: "Please enter your last name",
    email: "Please enter a valid email address",
},

submitHandler: function(form) {
    $.fn.serializeObject = function() {
        var o = {};
        var a = this.serializeArray();
        $.each(a, function() {
            if (o[this.name] !== undefined) {
                if (!o[this.name].push) {
                    o[this.name] = [ o[this.name] ];
                }
                o[this.name].push(this.value || '');
            } else {
                o[this.name] = this.value || '';
            }
        });
        return o;
    };

    var evdata = JSON.stringify($('#evaluatorForm').serializeObject());
    $.ajax({
        type : 'POST',
        url : '/nhp/rest/evaluator/insertEvaluator',
        contentType : 'application/json',
        data : evdata,
        success : function() {
            alert("Added Successfully");
            $('#evaluatorForm').trigger("reset");

        },
    });

}

}

    evdata.setRoles(roles);
    evaluatorService.create(evdata);


} catch (BusinessException e1) {
    e1.printStackTrace();
}

    return  "success";
}
