  • AngularJS(10)-数据验证

    AngularJS 表单和控件可以提供验证功能,并对用户输入的非法数据进行警告。客户端的验证不能确保用户输入数据的安全,所以服务端的数据验证也是必须的。

    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>数据验证</title>
        <script src="angular-1.4.1/angular.min.js"></script>
    </head>
    <body>
    
    <h2>数据验证</h2>
    
    <form  ng-app="myApp"  ng-controller="validateCtrl"
           name="myForm" novalidate>
    
        <p>用户名:<br>
            <input type="text" name="user" ng-model="user" required>
      <span style="color:red" ng-show="myForm.user.$dirty && myForm.user.$invalid">
      <span ng-show="myForm.user.$error.required">用户名是必须的。</span>
      </span>
        </p>
    
        <p>邮箱:<br>
            <input type="email" name="email" ng-model="email" required>
      <span style="color:red" ng-show="myForm.email.$dirty && myForm.email.$invalid">
      <span ng-show="myForm.email.$error.required">邮箱是必须的。</span>
      <span ng-show="myForm.email.$error.email">非法的邮箱。</span>
      </span>
        </p>
    
        <p>
            <input type="submit"
                   ng-disabled="myForm.user.$dirty && myForm.user.$invalid ||
      myForm.email.$dirty && myForm.email.$invalid">
        </p>
    
    </form>
    
    <script>
        var app = angular.module('myApp', []);
        app.controller('validateCtrl', function($scope) {
            $scope.user = 'John Doe';
            $scope.email = 'john.doe@gmail.com';
        });
    </script>
    
    </body>
    </html>
