javascript - Capturing 'escape' keypress in ReactJS - Stack Overflow

I have a React app with the following structure:

<App>
  <Input/>
  <Lists>
    <List>
    .
    .
    <List/>
   </Lists>
</App>

Each list has modify button which makes the list display an input field if clicked and some text otherwise by toggling modify(a boolean state).

What I want to achieve is that on clicking the escape key user should be able to switch between both (the input field and the text).

What I've tried:

1. Use document.addEventListener, but I could not access the event handler (which is in the List class), I couldn't add it inside the class itself as it assumes List.document to be a property.

2. Use the onKeyPress synthetic event

I couldn't figure out how to add it to the app ponent (I want the user to click escape anytime, not focus on the input field or something and then press escape)

I added it to the Input field (the one replaced by the text in List) but it didn't work (It works with the enter key, I used event.key==='Escape'). I console logged the event and nothing es up while it works fine for the Enter key.

All suggestions appreciated :).

The escape key does not fire keypress event. You're going to want to listen for the keydown event.

class App extends PureComponent {
    // ...

    ponentDidMount() {
        window.addEventListener('keydown', callback);
    }

    ponentWillUnmount() {
        window.removeEventListener('keydown', callback);
    }

    // ...
}
