React-da select bilan ishlash
Keling, endi
select
ochiladigan ro‘yxatlar bilan shug‘ullanamiz.
Ularni boshqarish ham deyarli input va checkboxlar
bilan ishlashdan farq qilmaydi.
Faraz qilaylik, bizda quyidagi select mavjud:
function App() {
return <div>
<select>
<option>text1</option>
<option>text2</option>
<option>text3</option>
<option>text4</option>
</select>
</div>;
}
Keling, uning ishlashini React vositalari bilan ta'minlaymiz:
function App() {
const [value, setValue] = useState('');
function handleChange(event) {
setValue(event.target.value);
}
return <div>
<select value={value} onChange={handleChange}>
<option>text1</option>
<option>text2</option>
<option>text3</option>
<option>text4</option>
</select>
<p>
sizning tanlovingiz: {value}
</p>
</div>;
}
Shaharlarning ochiladigan ro‘yxatini yarating. Shuningdek, foydalanuvchi tanlovi chiqariladigan abzats ham yarating.
