离开路线时的Ember清理

问题描述

我想在离开路线时进行一些清理，例如停止计时器。为此，我需要一个在离开路线时触发的事件，我需要访问该事件的控制器实例。

有一个退出事件，但它没有任何参数，而 this.get（'controller'）里面也不行 - 返回

在退出事件中是否有正确的方法来获取控制器实例，或者也许是我不知道的另一个事件？

我设置有一个我想要的例子。

解决方案

你可以实现这个通过调用 this.controllerFor（'home'）。您可以尝试。

这有点恼人，所以最近，您可以直接使用 this.controller ，您可以看到。

I want to make some cleanup when i leave route, like stopping timers. For that i need an event that triggers when leaving the route, and i need access to instance of controller inside of that event.

There is an exit event, but it doesn't get any arguments, and this.get('controller') inside it doesn't work too - returns undefined.

Is there a proper way for obtaining controller instance in the exit event, or, maybe, another event that i don't know of?

I setup this fiddle with an example of what i want..

解决方案

You can achieve this by calling this.controllerFor('home'). You can try it in this JSFiddle.

This is a little bit annoying, so a pull request has been merged recently that allows you to directly use this.controller, as you can see in this JSFiddle.
