AngularJS:从 bootstrap-ui 手风琴访问范围 [英] AngularJS: access scope from bootstrap-ui accordion

问题描述

我正在尝试 $watch 以查看 ui-bootstrap 手风琴中模型的更改.绑定在视图中起作用，但是当模型更改时，$watch 不会触发.

如何在控制器中获取 $scope.myModel 的值?

解决方案

使用对象而不是原始类型:

<手风琴><accordion-group 标题="静态标题"><输入 ng-model="model.myModel">{{ 模型.myModel }}</accordion-group></手风琴>

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

I'm trying to $watch for a change on a model within a ui-bootstrap accordion. Binding works within the view, but when the model changes, the $watch doesn't fire.

How do I get the value of $scope.myModel in the controller?

解决方案

Use an object rather than a primitive:

<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);
  })
}
