如何在角度中做单选按钮

Question

这是我的代码。当我提交 switchColors 时，服务器返回未定义。这是怎么错的？

另外，我应该如何在控制器中启动$scope.swichColors？目前我有 $scope.switchColors = '';

<label class="radio-inline">
    <input type="radio" ng-model="$parent.switchColors" value = "yes" >Yes</input>
</label>
<label class="radio-inline">
    <input type= "radio" ng-model = "$parent.switchColors" value = "no" >No</input>
</label>

Answer 1

尝试使用 ng-value 而不是 value

 <label class="radio-inline">
        <input type="radio" ng-model="$parent.switchColors" ng-value = "yes" >Yes</input>
    </label>
    <label class="radio-inline">
        <input type= "radio" ng-model = "$parent.switchColors" ng-value = "no" >No</input>
    </label>
