Angular.js最佳实践 - 扩展的控制器，覆盖控制器默认 [英] Angular.js best practice - extending controllers, overriding controller defaults
问题描述
下面是一个真实的角度的问题，我不能绕到我的头。
我喜欢棱角分明，但现在这个问题是窃听了我很多。
Here is a real-life Angular problem I can't wrap my head around. I love Angular, but this issue is bugging me a lot right now.
什么是扩展现有的控制器的功能，并使用扩展的控制器我的应用程序的其他页面上的最佳做法？
换句话说：如何做控制器基业角
What is the best practice to extend an existing controllers's functions, and use the extended controller on an other page of my application? In other words: How to do controller inheritance in Angular?

推荐答案
半年，我认为我完全理解这是怎么回事了。
由于它是在这条信息的评论中指出，最简单的答案是服务。
After half a year I think I understand completely what's going on. As it is pointed out in a comment to this post, the simplest answer is services.
在最理想的情况下，你的所有范围变量都是从工厂/服务聚集值。不过，你可能想用一个额外的功能，使用相同的控制器：$ scope.someFunction（）{}，并保持休息。在这种情况下，你有一个薄控制器逻辑，这是理想的控制器的设计 - 但仍可能落得个百人以上线code的。你不想在一个其他的控制器被复制，只是因为你需要一些额外的控制器逻辑（如$ scope.someFunction（））
In the most optimal case, all your scope variables are values gathered from a factory/service. Still, you might want to use the exact same controller with one extra function: $scope.someFunction(){}, and keep the rest. In this case, you do have a 'thin' controller logic, which is the desirable controller design - but may still end up a hundred or more lines of code. You don't want that being duplicated in an other controller, just because you need some extra controller logic (like $scope.someFunction() )
那你怎么办呢？
答案是这样的：
- 确保你做的一切都是为了解决工厂的情况
-
如果你是abolutely一定你做了，去的控制器注入：
- Make sure that you did everything in order to solve the situation with factories
if you are abolutely certain you did, go for the controller injection:
.controller（'childController'，函数（$范围，$控制器）{
使用严格的;
$控制器（'parentController'，{$范围：$范围}）;
$ scope.someFunction =功能（）{}
}）
就这么简单。 - 再次，通常情况下，事情可以与工厂解决。
It's that simple. -- again, usually, things can be solved with factories..
