从第三方子组件更新父状态

Question

I am trying to figure out how to grab the state from a 3rd party component (which will be an array of objects) and use it to update the state in the parent component so I can access the data and do other stuff with it.

Since the child component is third party I can not modify it and add any kind of change handler to it to pass state up.

How can I achieve this?

This answer has the basic idea, although you'll want to use innerRef and React.createRef() . And as you mentioned, the current state can be grabbed using this.insertRefHere.current.state .
