Laravel 5.2电子邮件独特的jquery验证

Question

我有一个bootstrap模式但是这里服务器端验证没有显示所以我试图在JQuery validate plugin中验证，我试图检查电子邮件，如果它在JQuery验证中是唯一的，但它仍然给我错误消息和不会提交

控制器：

 public function register(Request $request){   
 $validation =$this->validate($request, [
            'name' => 'required',
            'email' => 'required|email|unique:users,'
            'password' =>'Required|AlphaNum|Between:6,8|Confirmed',
            'password_confirmation' =>'Required|AlphaNum|Between:6,8'

        ]);

      $users = new User([
            'name' => $request['name'],
            'email' => $request['email'],
            'password' => bcrypt($request['password']),
        ]); 
      $users->save(); 


         return redirect()->route('product.index')
                        ->with('success', 'welcome');
        }

//
        public function validateEmail(Request $request)
 {

          $validator = Validator::make($request->all(), [
            'email' => 'required|email|unique:users',
         ]);

         if($validator->fails()){
        return Response::json(array(
            'fail' => true,
            'errors' => $validator->getMessageBag()->toArray()
        ));
         }else {

        return Response::json(array(
          'success' => true,
          'email' => $request->input('email')
        ));
 }

 }

JavaScript的：

           $.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
    $(".register").submit(function (e) {

        e.preventDefault(); 



var form=$('.registerform');



        $.ajax({

            type: "POST",

            url: $form.attr('action'),
        data:form.serialize(),

            dataType: 'json',
success: function(result) {
    if (response.status == "OK") {
      console.log ('success');//Success!
      $('#register').modal('hide');
      $('.register').attr("disabled", false);
    } else {
      console.log ('failure');//Fail!
      $(".errors").html(result.errors);
      $('.register').attr("disabled", false);
    }
  }



        });


    });
     $.validator.addMethod("remote", 
        function(value, element) {
            var result = false;
            $.ajax({
                type:"get",
                url: "/email", // script to validate in server side
                 data:form.serialize(),

            });

            // return true if username is exist in database
            return result; 
        }, 
        "This email is already taken! Try another."
    );


 $.validator.addMethod("PASSWORD",function(value,element){
                return this.optional(element) || /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{6,8}$/i.test(value);
            },"Passwords are 6,8 characters with uppercase letters, lowercase letters and at least one number.");

    $(".register").click(function () {

        form = $(".registerform");

        $('.registerform').validate({
             wrapper: "li",

        rules:{
        name:{
            required:true,
        },
        password:{
            required:true,
              PASSWORD : true
        },
       // password_confirmation: {required: true},

        email:{
           required:true,
            email:true,
           remote:true



        }
    },
    messages:{
        name:{
            required:"Please provide your Login",
        },
        password:{
            required:"Please provide your password",

        },
       email:{
            required:"Please provide your email adress",
            email:"it should be an email",
            //remote:  "This email is already taken! Try another."


        },
        ///password_confirmation:{
            required:"Please provide your password",
           // equalTo:"it should be equal to password"
   // }


    }
      });

      });
