在组件内部调用闭包动作的正确方法是什么？

Question

我将闭包动作传递给我的组件，如下所示：

{{deployment-timeline loadMoreDeployments=(action "loadMoreDeployments")}}

我应该如何在我的组件中调用它？

actions:{
  loadMoreDeployments(){
    // which one of the following three invocations is best?
    this.attrs.loadMoreDeployments();
    this.get('loadMoreDeployments')();
    this.loadMoreDeployments();
  }
}

Answer 1

你应该做

this.get('loadMoreDeployments')();

或

import {get} from '@ember/object';
...
get(this, 'loadMoreDeployments')();

从未引入attrs的使用，不建议使用带点符号访问ember对象上的属性。

修改：With ember 3.1 (currently in beta) we will get support for dot notation for getters (no setters yet, and not for proxy objects).这意味着您可以从ember 3.1安全使用：

this.loadMoreDeployments();
