html - Angular JS HTML5 验证

Question

我有一个表单，我在我的输入中使用了 required 标签 - 这工作正常但在我的提交按钮上我有 ng-click="visible = false" 在提交数据时隐藏表单。

如果所有验证都正确，我怎样才能让它只设置为 false？

App.js

 $scope.newBirthday = function(){

        $scope.bdays.push({name:$scope.bdayname, date:$scope.bdaydate});

        $scope.bdayname = '';
        $scope.bdaydate = '';

    };

HTML:

 <form name="birthdayAdd" ng-show="visible" ng-submit="newBirthday()">
        <label>Name:</label>
        <input type="text" ng-model="bdayname" required/>
        <label>Date:</label>
        <input type="date" ng-model="bdaydate" required/>
        <br/>
        <button class="btn" ng-click="visible = false" type="submit">Save</button>
      </form>

如果您为表单命名，FormController 将根据其名称在最近的 Controller 范围内公开。所以在你的情况下，你有一个类似的结构

<div ng-controller="MyController">
    <!-- more stuff here perhaps -->
    <form name="birthdayAdd" ng-show="visible" ng-submit="newBirthday()">
        <label>Name:</label>
        <input type="text" ng-model="bdayname" required/>
        <label>Date:</label>
        <input type="date" ng-model="bdaydate" required/>
        <br/>
        <button class="btn" ng-click="onSave()" type="submit">Save</button>
      </form>
</div>

现在在你的 Controller 中

function MyController($scope){
    // the form controller is now accessible as $scope.birthdayAdd

    $scope.onSave = function(){
        if($scope.birthdayAdd.$valid){
            $scope.visible = false;
        }
    }
}

如果表单中的输入元素有效，则表单有效。希望这可以帮助。
