AngularJS:从 bootstrap-ui Accordion 访问范围

Question

我正在尝试$watch ui-bootstrap Accordion 中模型的更改。绑定(bind)在 View 中起作用，但是当模型更改时，$watch 不会触发。

如何获取 Controller 中 $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);
  })
}
