Ember.js 余烬，要重定向的组件

在我的ember应用程序中，我有一个

活动

路线，带有相应的路线、控制器和一些组件，模板包含：

{{#each activities as |activity|}}
    <li>{{carousel-block activity=activity}}</li>
  {{/each}}

{{carousel activities=model}}

carousel活动

包含：

{{#each activities as |activity|}}
    <li>{{carousel-block activity=activity}}</li>
  {{/each}}

块组件用于监视

panDown

，当事件发生时，块会将浏览器重定向到“活动详细信息”页面

#app/controllers/activities.js
import Ember from 'ember';

export default Ember.Controller.extend({

});

---

---

如果加载“活动”路径并向下滑动（引发panDown事件），则控制台中会出现以下错误：

panDown

不能从组件调用transitionon（）。最好的方法是发送一个操作，这将从控制器进行转换

export default Component.extend(RecognizerMixin, {
  recognizers: 'pan',
  panDown() {
    console.log("panDown");
    this.attrs.showDetailsAction(this.get('activity'));
  }
});

然后在控制器中定义操作：

export default Ember.Controller.extend({
  actions: {
    showDetails(activityData) {
      this.transitionToRoute('activity', activityData);
    }
  }
});

并将操作传递给组件：

{{carousel-block activity=activity showDetailsAction=(action 'showDetails')}}

我是否应该将模板中的操作也传递给

旋转木马活动

和

{{{carousel activities activities=model showtailsaction=（操作“showtails”）}

？是的，对不起。因此，您将执行

{{carousel activities activities=model showDetailsAction=（action'showDetails'）}}

，然后

{{{carousel block activity=activity showDetailsAction=attrs.showDetailsAction}

我是否应该将模板中的操作也传递给

carousel activities

{{carousel activities activities=model showDetailsAction=（action'showDetails'）}？是的，对不起。所以您要执行

{{{carousel activities activities=model showDetailsAction=（action'showDetailsAction'）}

然后执行

{{carousel block activity=activity showDetailsAction=attrs.showDetailsAction}
