someModule.factory('greeter', ['$window', function(renamed$window) { ...; }]); 记住,所有注释风格都是等价的,可以被用在支持injection的angular中的任何地方。 三、Where can I user DI? DI遍及整个angular。它通常使用在controller和factory方法中。 1. DI in controllers controller是负责(描述)应用行为...
Angular的注入器子系统(Angular是由多个系统组成)是负责创建组件,解决它们之间的依赖关系,并且根据它们的需要,给它们提供所需要的组件的实例。 使用依赖注入 依赖注入(DI)是贯通了整个angularjs的。当这个组件定义了,或者在module的run 方法config 方法中定义了它们,你就可以在这个module的任何地方使用这个组件了。 1、...
这一节我们来讲讲AngularJS中的依赖注入,在实际开发中Angular提供了具体的方法供我们去调用,但是一旦业务不能满足要求或者出现麻烦或者错误时导致无从下手,所以基于此我们有必要深入一点去了解内部的基本原理,这样我们才能将Angular玩弄于鼓掌之间。 话题 在讲述依赖注入时我们有必要讲一讲一个组件decorator(暂且叫做装饰...
I'm new at Angular and trying to do a basic dependency injection to get the hang of it. In this example I'm trying to dependency inject a service to a controller, and I'm getting the following error. Error: [$injector:unpr] Unknown provider: $scopeProvider <- $scope <- testInjectio...
Part1: What is Dependency injection 依赖注入定义为组件之间依赖关系由容器在运行期决定,形象的说即由容器动态的将某个依赖关系注入到组件之中在面向对象编程中,我们经常处理的问题就是解耦,控制反转(IoC)就是常用的面向对象编程的设计原则,其中依赖注入是控制反转最常用的实现。目标解决当前类不负责被依赖类实例的创...

In cases like this, you can use a factory provider. Factory providers can also be useful when creating an instance of a dependency from a third-party library that wasn't designed to work with DI. Previous:Dependency Injection in Angular ...
Nject is a simple nodejs library for handling dependency tree resolution and injection, inspired by angularjs's DI system. It maps variable names to registered dependencies at time of injection. Here's how it looks... varnject=require('nject');vartree=newnject.Tree();tree.constant('a',...
