AngularJS：来自bootstrap-ui手风琴的访问范围

Question

我试图在ui-bootstrap手风琴中观察模特的变化。绑定在视图中工作，但是当模型更改时，$ watch不会触发。

如何在控制器中获取$ scope.myModel的值？

Answer 1

使用对象而不是基元：

<div ng-controller="AccordionDemoCtrl">
  <accordion>
    <accordion-group heading="Static Header">
      <input ng-model="model.myModel"> {{ model.myModel }}
    </accordion-group>
  </accordion>
</div>

angular.module('plunker', ['ui.bootstrap']);
function AccordionDemoCtrl($scope) {
  $scope.model = {myModel: ''};
  $scope.$watch('model.myModel',function(){
    console.log($scope.model.myModel);
  })
}
