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>
