Select items from an array in React
Let's say we have an array with the texts of the drop-down list items:
function App() {
const texts = ['text1', 'text2', 'text3', 'text4'];
const [value, setValue] = useState('');
return <div>
...
</div>;
}
Let's form our option
tags in a loop:
function App() {
const texts = ['text1', 'text2', 'text3', 'text4'];
const [value, setValue] = useState('');
const options = texts.map((text, index) => {
return <option key={index}>{text}</option>;
});
return <div>
<select value={value} onChange={(event) => setValue(event.target.value)}>
{options}
</select>
<p>
your choice: {value}
</p>
</div>;
}
Let the array store a list of cities. Use a loop to output a drop-down list of these cities.
