Update (8 Jul. 2020): In the above code, I now use the useRef() React hook, instead of document.getElementById(), to refer to the hidden input element. For why we should use useRef() instead of… If you’re using React 16.3+, the suggested way to create refs is using React.createRef (). A Ref variable in React is a mutable object, but the value is persisted by React across re-renders. A ref object has a single property named current making refs have a structure similar to { current: ReactElementReference }.
React Ref for read/write Operations. So far, we have used the DOM ref only for read operations (e.g. reading the size of a DOM node). It's also possible to modify the referenced DOM nodes (write operations). The next example shows us how to apply style with React's ref without managing any extra React state for it:
A Ref variable in React is a mutable object, but the value is persisted by React across re-renders. A ref object has a single property named current making refs have a structure similar to { current: ReactElementReference }. The decision by the React Team to make refs persistent and mutable should be seen as a wise one.
