display errors returned from controller laravel

i want to display json errors returned from controller in ajax success function i am getting errors like

{"message":"The given data was invalid.","errors":{"user_phone":["The user phone must be a number."],"user_email":["The user email must be a valid email address."]}}

i want to display those errors on specific input if not, just give me a solution so that i will get every input error in a variable like var email = [//all errors related to email];

please ask me any inputs you want from my side

these is my ajax code

  $.ajax({
      url: "register/submit", 
      type: "post",
      headers: {
          'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
      },
      data: {'user_firstname':user_firstname,'user_lastname':user_lastname,'user_phone':user_phone,'user_email':user_email,'user_username':user_username,'password':user_password,'password_confirmation':user_password_confirmation},
      success: function(result){

         console.log(result);
       }
    });

}

here is my controller code

public function submit(Request $request)
{
   Validator::make($request->all(), [
    'user_firstname' => 'required|string|max:255',
    'user_lastname' => 'required|string|max:255',
    'user_phone' => 'required|numeric|max:15|unique:users,user_phone',
    'user_email' => 'required|email|unique:users,email',
    'user_username' => 'required|string|max:255|unique:users,username',
    'password' => 'required|string|min:6|confirmed',
    'password_confirmation' => 'min:6|same:password',
    ])->validate(); 


}
