php - 显示自定义错误消息

Question

我试图在表单验证中显示错误。但是这些消息总是可见的。

<form name="user-form" method="POST" action="{{route('registrationUser')}}">
    <div class="col-lg-8">
              Логин <input type="text" name="log" ng-model="mobile"   required pattern="[a-zA-Z ]*"><br>
               <span class="help-block" ng-show="errors.log[0]"><p>Только английский</p></span>
         </div>

          Пароль <input type="text" name="pass" ng-minlength="8" ng-pattern="regex" required pattern="[a-zA-Z]{8,32}" ><br>
         <div ng-show="user-form.pass.$error.pattern">Name doesn't match pattern!</div>
         <button ng-click='SaveUser()' name="Регистрация">Регисрация</button>
 </form>

Answer 1

您可以向 ng-show 添加另一个条件

<div ng-show="user-form.pass.$error.pattern && buttonclicked">Name doesn't match pattern!</div>

并在您的控制器中将该条件设置为 true

$scope.SaveUser= function () {
    $scope.buttonclicked = true;
};

所以只有当用户点击提交按钮时错误消息才会可见
