AngularJS我在哪里可以访问加载的控制器的范围？

Where can i access the scope of a loaded controller ? I like to have something like a event after the scope has been initialized for a controller to predefine the model for the view.

我在哪里可以访问加载的控制器的范围?在为控制器初始化范围之后,我希望有类似事件的事件,以便为视图预定义模型。

Is there something like $rootScope.$on("$controllerLoaded")

是否有类似$ rootScope。$ on(“$ controllerLoaded”)

It's not too clear, but it sounds like you want something to notify another part of an app after a particular controller is loaded. Is that correct?

它不太清楚,但听起来你想要在加载特定控制器后通知应用程序的另一部分。那是对的吗?

If so, you have a couple options. Try looking into $emit. Essentially sends a signal to parent listeners.

如果是这样,你有几个选择。试着查看$ emit。基本上向父听众发送信号。

Here is a write-up of using $emit & $broadcast

这是一个使用$ emit&$ broadcast的文章

$rootScope.$on('emitName', function(){
    //do what you want
});

Another option (more of a hack) would be to set a flag at the end of your controller:

另一种选择(更多的是黑客攻击)是在控制器的末尾设置一个标志:

$rootScope.controllerLoaded = true

Then wherever you are wanting to know when it is done, simply check the $rootScope.controllerLoaded flag.

然后,无论您想知道何时完成,只需检查$ rootScope.controllerLoaded标志即可。
