导航时是否可以防止损坏Angular组件? [英] Is it possible to prevent the destruction of Angular components when navigating?

问题描述

假设我有两个Angular 2组件:ComponentA和ComponentB. 我希望能够从ComponentA导航到ComponentB，然后最终回到ComponentA，而不必重新初始化ComponentA.

Assuming I have two Angular 2 components: ComponentA and ComponentB. I want to be able to navigate from ComponentA to ComponentB and then eventually back to ComponentA, while not having to reinitialize ComponentA.

在当前的Angular 2 Router实现中，每次我离开某个组件时，该组件都会被破坏，并且下次我导航至该组件时必须重新创建该组件.

In the current Angular 2 Router implementation, every time I navigate away from a component, the component gets destroyed and has to be recreated the next time I navigate to it.

我知道我可以通过使用Service来保留组件的状态，但这似乎比实际解决方案更像是一种解决方法.有什么办法解决吗?

I know that I can preserve the state of components by using a Service, but this seems to be more like a workaround than an actual solution to my issue. Is there any way around this?

推荐答案

是的，您需要实现，并为重用组件的路由定义行为.

and define a behavior for routes that reuse components.
