AngularJS 简单的点击计数器不起作用

Question

我正在尝试构建计数器功能。我正在使用 AngularJS 和 Bootstrap 按钮组，我不确定冲突在哪里。下面是我的代码。有人可以帮忙吗？

  <label class="btn btn-warning btn-sm">
    <input type="radio" name="radioSecondBy" ng-click = "yesCount = yesCount+1" id="vNo" autocomplete="off"> No
  </label>
  <label class="btn btn-info btn-sm">
    <input type="radio" name="radioSecondBy" ng-click = "yesCount = yesCount+1" id="vAbstain" autocomplete="off"> Abstain
  </label>
</div>

{{yesCount}}

</div>
<script>
var app = angular.module('meetingDetail', []);
app.controller('meetingDetailCtrl', function($scope) {
    $scope.yesCount= 0;
});
</script>

</body>
</html>

单选按钮没有点击事件。

将点击事件放在标签而不是单选按钮上

像这样

  <label ng-click = "yesCount = yesCount+1" class="btn btn-info btn-sm">
    <input type="radio" name="radioSecondBy"  id="vAbstain" autocomplete="off"> Abstain
  </label>

Answer 2

ng-click 不适用于单选按钮。您可以使用 ng-change 或观察变量

1) ng-改变

<input type="radio" name="radioSecondBy" ng-change= "yesCount = yesCount+1" id="vYes" autocomplete="off">Yes

2) $手表

$scope.$watch('yesCount', function(value) {
       $scope.yesCount = $scope.yesCount + 1;
 });
