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.但是你也可以从作用域中读取它作为对象参数,但我会使用参数,这会让你的服务接口更加清晰.
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.
