问题描述
我有Angular 组件，第一个组件使用第二个作为指令.它们应该共享在第一个组件中初始化的相同模型对象.如何将该模型传递给第二个组件?
I have Angular components and first component uses the second one as a directive.They should share the same model object, which is initialized in the first component.How can I pass that model to the second component?
推荐答案
组件2，指令组件可以定义一个输入属性(Typescript中的@input注解).组件 1 可以将该属性从模板传递给指令组件.
Component 2, the directive component can define a input property (@input annotation in Typescript). And Component 1 can pass that property to the directive component from template.
