Question

Can i know How to handle events in a Music Shop Application using React?

Answer 1

In a Music Shop Application using React, event handling is crucial for user interactions. Here's how to manage events effectively:

Using Event Handlers

Attach event handlers like onClick, onChange, etc.

<button onClick={handleBuy}>Buy Now</button>

Handling Input Changes

Use state to capture user inputs like search or quantity selection.

const [search, setSearch] = useState('');

<input type="text" value={search} onChange={(e) => setSearch(e.target.value)} />

Managing Cart Actions

Add items to the cart with event handlers.

const addToCart = (item) => setCart([...cart, item]);

<button onClick={() => addToCart(item)}>Add to Cart</button>

Handling API Requests

Fetch products dynamically.

useEffect(() => {

  fetch('/api/products')

    .then(res => res.json())

    .then(data => setProducts(data));

}, []);

Event Delegation (For Lists)

Handle click events for multiple items efficiently.

const handleItemClick = (id) => console.log(`Clicked item ${id}`);

<ul>

  {products.map((item) => (

    <li key={item.id} onClick={() => handleItemClick(item.id)}>{item.name}</li>

  ))}

</ul>
