您需要为每个value添加input，以便有角色可以锁定，并且如果您只是想知道某些内容发生了变化，请使用ng-change。

<input type="radio" name="country" ng-model='country' value='india' ng-change="change()"> India
<input type="radio" name="country" ng-model='country' value='uk'  ng-change="change()"> UK
<input type="radio" name="country" ng-model='country' value='germany' ng-change="change()"> Germany
<input type="radio" name="country" ng-model='country' value='france' ng-change="change()"> France
