Angular 2.0 中 $scope 的替代方案 [英] Alternative to $scope in Angular 2.0

问题描述

在 Angular 2.0 中，将没有 $scope.

有什么替代方案?我将如何能够在组件之间共享数据?scope 选项在指令中可用吗?更实际的是，目前有没有我可以熟悉的替代方法?

我知道 controller as 但我读到控制器也将被淘汰.

对 Angular 团队已经开始的这样一场革命感到困惑.

解决方案

Angular 2.0 正在使用 this 而不是 $scope.

2.0 中的主要变化之一是控制器的死亡，以及对组件的新强调.转向基于组件的应用程序的一大优势是更容易定义它们的接口；此外，HTML 元素已经在事件、属性和属性中具有易于映射的界面.

In Angular 2.0, there will be no $scope.

What is the alternative to that? How will I be able share data between the components? Will the scope option be available in directives? More practically, is there a current alternative to that that I can get acquainted with?

I am aware of controller as but I read that controllers will be eliminated too.

Confused on such a revolution the Angular team has started.

解决方案

Angular 2.0 is using this instead of $scope.

One of the major changes coming in 2.0 is the death of the controller, and a new emphasis on components. Big advantage of moving towards component-based apps is that it's easier to define their interfaces; plus, HTML elements already have an easily mappable interface in events, attributes, and properties.
