React 嵌套子组件的访问状态

Question

I need to access (read and manipulate) the state of a different component. Unfortunately the case isn't just a "simple" Parent <-> Child relation, but a bit more complicated.

SendResults has a button on which if I click I want to read a state property of the Vote component.

I don't really know how to solve this the problem.

Here's the Component Graph:

 Table TableHeader TableBody ResultRow Result Result ParticipantRow Vote Vote TableFooter SendResults

Answer 1

You can use Context API (for a simple use-case like this).

The question that always comes after "Should I use a state management library like Redux or MobX instead" .
