本文实例讲述了AngularJS实现的获取焦点及失去焦点时的表单验证功能。分享给大家供大家参考,具体如下:

<!DOCTYPE html>
<html ng-app="formExample">
<head>
  <meta charset="UTF-8">
  <title></title>
  <script src="../js/angular.js"></script>
  <script>
    angular.module('formExample', [])
        .controller('FormController', ['$scope', function($scope)
        {
          $scope.userType = 'guest';
          $scope.change = false;
        }]);
  </script>
</head>
<body>
<form name="myForm" ng-controller="FormController">
  userType: <input name="input" ng-model="userType" ng-blur="change=true" ng-focus="change=false" required>
  <span class="error" ng-show="myForm.input.$error.required && change">必填项</span><br>
</form>
</body>
</html>

运行效果:
