angularJS 表单验证仅适用于第一次

Question

我正在使用 angularjs 进行表单验证，到目前为止我已经完成了 99%。但问题是我的表单验证仅在第一次提交时才正确。解释起来很混乱，但我会尽力解释：P。就是这样。当我重置表单时，它显示字段为空的错误消息（应该如此）。像这样

之后，如果我填写 2 个字段并再次提交，我将正常工作。就像这样

我的问题来了

我的代码

<form name="userForm" ng-submit="submitForm(userForm.$valid, user)" novalidate>


        <!-- NAME -->
        <div class="form-group" ng-class="{ 'has-error' : userForm.name.$invalid && userForm.name.$dirty && submitted || (userForm.name.$invalid && userForm.name.$pristine) && submitted }">
            <label>Name*</label>
            <input type="text" name="name" class="item-input-wrapper" ng-model="user.name"  required>
            <label><p ng-show="submitted && userForm.name.$error.required" class="help-block "><font color="#009ACD">You name is required.</font></p></label>
        </div>

         <!-- EMAIL -->
        <div class="form-group" ng-class="{ 'has-error' : userForm.email.$invalid && userForm.email.$dirty && submitted || userForm.email.$invalid && userForm.email.$pristine  && submitted  }">

Answer 1

$setPristine();可能对您要查找的内容有用。尝试像下面这样添加...

<button class="button" type="reset" ng-click="form.$setPristine()">Reset</button>

有关更多信息和工作演示，请参阅以下链接

AngularJS does not proper handle button type="reset"?

您也可以参考以下链接将表单设置为原始状态

Reset form to pristine state (AngularJS 1.0.x)

Answer 2

找到解决办法

在你的控制器里面添加这个

$scope.reset = function() {
            $scope.user = angular.copy($scope.orig);
            $scope.userForm.$setPristine();

};

这里 'userForm' 应该是您的表单名称，而 'user' 应该是您的模型。

这对我有用。试试吧。

<form name="forms.sample" novalidate>

        <md-input-container class="md-block" flex-gt-sm>
            <label>Name:</label>
            <input ng-focus="focus=true" ng-blur="focus=false" style="width:400px;" class="form-control" name="Name" type="text" data-ng-model="Name" ng-pattern="SomePattern" required placeholder="enter the Name here" />
            <div ng-messages for="forms.sample.Name.$error" ng-if="!focus">
                <div ng-if='forms.sample.Name.$touched' ng-message="required">This is required.</div>
                <div ng-if='forms.sample.Name.$touched' ng-message="pattern">Enter a valid domain name</div>
            </div>
        </md-input-container>    
    </form>
