Using the onKeyUp and onKeyDown functions to detect when the spacebar key is pressed

Question

Using the onKeyUp and onKeyDown functions to detect when the spacebar key is pressed

Is there a way for my function to be triggered by either clicking a button or pressing the spacebar?

I have managed to make it work partially, but it's not quite right.

This is the function in question:

const showText = () => {
    const x = ToughSpellings.toString();
    console.log(x);
}

These are the actions for the button and spacebar:

<input type="text" id="one" onKeyUp={showText} />

<button onClick={showText}>Show Next Letter</button>

I'm struggling to figure out how to incorporate the onKeyUp event without using an input field. How can I make this function work when the user is just browsing the website?

To detect keyboard input without utilizing an input field, you would set up a document event listener to catch keyboard events.

You can implement the following code within your React component:

const keyDownHandler = (event) => {
    console.log(event.keyCode); // Pressing the UP arrow key would log `38`
    // Implement functionality based on the pressed key using `event.keyCode`
};

useEffect(() => {
    document.addEventListener("keydown", keyDownHandler);
    return () => document.removeEventListener("keydown", keyDownHandler);
}, []);
