Basic Search Implementation
This example demonstrates a simple search feature where users can input a search query, and the application filters a list of items based on that query.
Example: Below is an example of implementing a basic search feature with React Hooks.
Javascript
import React, { useState, useEffect} from 'react';function SearchFeature() { const [query, setQuery] = useState(''); const [filteredItems, setFilteredItems] = useState([]); const items = ['apple', 'banana', 'orange', 'grape', 'watermelon']; useEffect(() => { const filtered = items.filter(item => item.toLowerCase().includes(query.toLowerCase()) ); setFilteredItems(filtered); }, [query]); return ( <div> <input type="text" placeholder="Search..." value={query} onChange={(e) => setQuery(e.target.value)} /> <ul> {filteredItems.map((item, index) => ( <li key={index}>{item}</li> ))} </ul> </div> );}export default SearchFeature; |
Output:
Ouput
Explanation of Output:
- We declare state variables query and filteredItems using the useState hook.
- Inside the useEffect hook, we filter the items array based on the current value of the query state.
- The filtered items are updated whenever the query state changes.
- The input element allows users to input their search query, which updates the query state accordingly.
- The filtered items are displayed as a list below the search input.
