AngularJS：添加检查密码输入是否一致的功能

利用AngularJS的directive，我们可以很方便的实现检验功能。代码如下：

 1 // 密码验证directive 2 ftitAppModule.directive(‘pwCheck‘, [function () { 3     return { 4         require: ‘ngModel‘, 5         link: function (scope, elem, attrs, ctrl) { 6             var firstPassword = ‘#‘ + attrs.pwCheck; 7             elem.add(firstPassword).on(‘keyup‘, function () { 8                 scope.$apply(function () { 9                     var v = elem.val()===$(firstPassword).val();10                     ctrl.$setValidity(‘pwmatch‘, v);11                 });12             });13         }14     }15 }]);

Demo html代码（feedback部分请参考http://www.cnblogs.com/ilovewindy/p/3795993.html）：

 1 <div class="form-group"> 2     <label for="userPassword">密码</label> 3     <input type="password" class="form-control" id="userPassword" name="userPassword" 4            placeholder="请输入密码" ng-model="selectedUser.userPassword"> 5 </div> 6 <div class="form-group has-feedback" 7      ng-class="{‘has-success‘ : !usrMgrForm.confirmPassword.$pristine && usrMgrForm.confirmPassword.$valid, 8                 ‘has-error‘ : !usrMgrForm.confirmPassword.$pristine && usrMgrForm.confirmPassword.$invalid }"> 9     <label for="confirmPassword">确认密码</label>10     <input type="password" class="form-control" id="confirmPassword" name="confirmPassword"11            placeholder="请再次输入密码" ng-model="selectedUser.confirmPassword" pw-check="userPassword">12     <div ng-show="!usrMgrForm.confirmPassword.$pristine && tagName.confirmPassword.$valid">13         <span class="glyphicon glyphicon-ok form-control-feedback"></span>14     </div>15     <div ng-show="!usrMgrForm.confirmPassword.$pristine && usrMgrForm.confirmPassword.$invalid">16         <span class="glyphicon glyphicon-remove form-control-feedback"></span>17     </div>18 </div>

效果如下：
