我想知道如何在AngularJS中使用指令按名称获取单选按钮的数量。

<label ng-repeat="elements in [1,2,3,4,5,6,7]">
      <input type="radio" name="phone" ng-model="phone" value="example"> 
</label>
<!--Directive by name (phone), number of radio buttons is 7-->
<label ng-repeat="elements in [1,2,3,4,5,6,7,8,9]">
      <input type="radio" name="OS" ng-model="OS" value="example"> 
</label>
<!--Directive by name (OS), number of radio buttons is 9-->

可能在作用域上赋值:$scope.myList = [1,2,3,4,5,6,7,8,9];。并在视图中显示列表的长度，如:{{ myList.length }} .
