How can I implement keyboard navigation in a React app?
You can implement keyboard navigation in a React app by using event listeners for key events and managing focus.
Can you give me a code example?
Sure! You can use the onKeyDown
event to handle key presses. Here's a simple example:
function App() {
const handleKeyDown = (event) => {
if (event.key === 'ArrowUp') {
// Move focus up
} else if (event.key === 'ArrowDown') {
// Move focus down
}
};
return (
<div tabIndex={0} onKeyDown={handleKeyDown}>
<p>Use arrow keys to navigate.</p>
</div>
);
}
What about accessibility considerations?
For accessibility, ensure that all interactive elements are focusable and provide clear visual indicators for focus states.
Are there libraries that can help with this?
Yes, libraries like react-aria
and react-router
can help manage keyboard navigation and improve accessibility.
