AngularJS提供了表单验证,但是验证的过程交互体验很不好,比如重设密码,重复密码的时候一键入就会提示密码不正确,现整理了两种方法,仅供借鉴。
一,点击提交验证
<form action="" class="form-horizontal col-md-9" name="reset_pwd" ng-submit="resetPwd()"> <div class="form-group"> <label class="col-sm-2 control-label">密码</label> <div class="col-sm-8"> <input type="password" name="mycompwd" class="form-control" ng-model="mycompwd" placeholder="请输入密码"> </div> </div> <div class="form-group"> <label class="col-sm-2 control-label">重复密码</label> <div class="col-sm-8"> <input type="password" name="resetmycompwd" class="form-control" ng-model="resetmycompwd" placeholder="再次输入密码" required> </div> <span style="color:red" ng-show="mycompwd!=resetmycompwd && reset_pwd.resetmycompwd.$dirty && reset_pwd.submitted ">密码不一致</span> </div> <div class="form-group"> <button type="submit" class="btn btn-primary" >确认</button> <button type="button" class="btn btn-default" ng-click="resetpwd_cancle()">取消</button> </div> </form>
当用户试图提交表单时,你可以在作用域中捕获到一个submitted值,然后对表单内容进行验证并显示错误信息。
JS代码
$scope.submitted = false; $scope.resetPwd = function(){ console.log(666); if($scope.reset_pwd.$valid && $scope.mycompwd == $scope.resetmycompwd){ console.log('重置成功,进行其他操作'); }else{ $scope.reset_pwd.submitted = true; } }
亲测可用。
第二种失去焦点验证
<form action="" class="form-horizontal col-md-9" name="reset_pwd" ng-submit="resetPwd()"> <div class="form-group"> <label class="col-sm-2 control-label">密  码</label> <div class="col-sm-8"> <input type="password" name="mycompwd" class="form-control" ng-model="mycompwd" placeholder="请输入密码"> </div> </div> <div class="form-group"> <label class="col-sm-2 control-label">重复密码</label> <div class="col-sm-8"> <input ng-focus type="password" name="resetmycompwd" class="form-control" ng-model="resetmycompwd" placeholder="再次输入密码" required> </div> <span style="color:red" ng-show="mycompwd!=resetmycompwd && reset_pwd.resetmycompwd.$dirty && !reset_pwd.resetmycompwd.$focused ">密码不一致</span> </div> <div class="form-group"> <button type="submit" class="btn btn-primary" >确认</button> <button type="button" class="btn btn-default" ng-click="resetpwd_cancle()">取消</button> </div> </form>
JS代码
app.directive('ngFocus',[function(){ var focusClass = 'ng-focused'; return{ restrict:'AE', require:'ngModel', link:function(scope,element,attrs,ctrl){ ctrl.$focused = false; element.bind('focus',function(e){ element.addClass(focusClass); scope.$apply(function(){ ctrl.$focused = true; }); element.bind('blur',function(e){ element.removeClass(focusClass); scope.$apply(function(){ ctrl.$focused = false; }); }); }) } }; }]);
注意HTML标红的地方。正是区分两种方法的关键。
