Ember App.Router.router.currentState未定义 [英] Ember App.Router.router.currentState undefined

问题描述

我想监视App.Router.router.currentState，以激活/停用导航链接。沿着这里所解释的一些内容： https://stackoverflow.com/a/13312466/674525

I want to monitor App.Router.router.currentState for the purpose of activating/deactivating the navigation links. Something along the lines as explained here: https://stackoverflow.com/a/13312466/674525

但是，currentState的属性似乎不再存在于路由器中。
App.get（'Router.router.currentState'）返回未定义。

However, the property currentState does not seem to exist in the router any more. App.get('Router.router.currentState') returns undefined.

我想，它在最近的Ember版本中更改。有另外一种方式吗？

I suppose, it changed in the recent Ember versions. Is there another way of doing this?

推荐答案

好的。得到这个解决了看来，currentPath是在applicationController实例中设置的。所以我这样做：

Ok. Got this solved. It seems that the currentPath is set in the applicationController instance. So I did this:

App = Em.Application.create({

    currentPath: '',

    ApplicationController : Ember.Controller.extend({
        updateCurrentPath: function() {
            App.set('currentPath', this.get('currentPath'));
        }.observes('currentPath')
    }),

    ...

});

然后，我可以从代码中的任何地方绑定或观察App.currentPath，并对其更改做出反应。

Then, I can bind or observe the App.currentPath from anywhere in the code and react on its changes.
