如何将数据注入到由路由器创建的Angular2组件中?

问题描述

我目前正在尝试为我们的Angular1应用程序(非常复杂的一个)构建Angular2原型(基于alpha44)，并且正在尝试使用路由和子路由时找到最佳的模型/数据架构.

I'm currently trying to build an Angular2 prototype (based on alpha44) of our Angular1 app (pretty complex one) and I'm trying to find the best model/data architecture when using routes and child routes.

在我的示例中，我想从通过路由创建的子组件中访问父组件的属性(托管router-outlet).

In my example, from a child component created from a route, I want to access a property of the parent component (hosting the router-outlet).

但是，当您从router-outlet创建组件时，就不能再使用@Input和@Output.那么，除了基本的routeParams和静态的routeData以外，注入一些数据/属性的最佳实践是什么?

But when you create a component from a router-outlet, you cannot use @Input and @Output anymore.So what is the best practice to inject some data/properties, except basic routeParams and static routeData?

如何在没有太多耦合的情况下与父组件进行通信?

How do you communicate with the parent component without too much coupling?

推荐答案

共享服务可以与路由器添加的组件一起使用.有关详细信息，请参见 https://angular.io/docs/ts/latest/cookbook/component-communication.html

A shared service can be used with components added by the router. For details see https://angular.io/docs/ts/latest/cookbook/component-communication.html

data支持也已添加到RC.4中的新路由器.有关详细信息，请参见如何传递数据Angular 2组件中同时使用路由?

data support also was added to the new router in RC.4. For details see How do I pass data in Angular 2 components while using Routing?

Angular 2-等效于路由器可能会为新路由器解析数据.
