将当前范围传递给 AngularJS 服务 [英] Passing current scope to an AngularJS Service

问题描述

将当前"$scope 传递给 AngularJS 服务是否正确?

Is it correct to pass the "current" $scope to an AngularJS service?

我的情况是我有一个 $service 知道它只被一个控制器使用，我想在 $service 方法本身中引用控制器的范围.

I'm in the situation where I've a $service knowing it's consumed by only one controller, and I'd like to have a reference to the controller's scope in the $service methods themselves.

这在哲学上正确吗?

或者我最好将事件广播到 $rootScope 然后让我的控制器监听它们?

Or I'd better to broadcast events to the $rootScope and then make my controller listen to them?

推荐答案

要让控制器知道异步发生时，请使用 Angular 承诺.

To let the controller know when something async happens, use Angular promises.

为了激发$apply，你不需要作用域，你可以调用$rootScope.$apply，因为在特定的调用它没有区别范围或在根中.

To provoke the $apply, you don't need the scope, you can call $rootScope.$apply, as there is no difference calling it in a specific scope or in the root.

关于变量读数，如果能收到参数就更好了.但是您也可以从范围中将其作为对象参数读取，但我会使用参数，这将使您的服务界面更加清晰.

Regarding the variable reading, it would be better if you received parameters. But you could also read it from a scope as an object parameter, but I would go with parameter, that would make your service interface much more clearer.
