替代Angular 2.0中的$ scope [英] Alternative to $scope in Angular 2.0

问题描述

在Angular 2.0中，将没有$scope.

In Angular 2.0, there will be no $scope.

有什么替代方法?如何在组件之间共享数据? scope选项在指令中可用吗?实际上，是否有我可以熟悉的替代方法?

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?

我知道controller as，但我知道控制器也将被淘汰.

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

对这样的革命感到困惑，Angular团队已经开始.

Confused on such a revolution the Angular team has started.

推荐答案

Angular 2.0 使用的是this而不是$scope.

2.0中的主要变化之一是控制器的消亡，以及对组件的新强调. 转向基于组件的应用程序的最大优势是定义它们的界面更容易.另外，HTML元素在事件，属性和属性上已经具有易于映射的界面.

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.
