React-daky sanawdan value atributlary selekta

Bolsa, ýene-de sanaw elementlerimiz sanawda saklanylsyn:

function App() {
	const texts = ['text1', 'text2', 'text3', 'text4'];
	const [value, setValue] = useState('');
	
	...
}

Geliň, bu sanawy ulanyp, option teglerini döredeliň we olara san elementleriniň mazmunyny value atributy hökmünde goşalyň:

function App() {
	const texts = ['text1', 'text2', 'text3', 'text4'];
	const [value, setValue] = useState('');
	
	const options = texts.map((text, index) => {
		return <option key={index} value={index}>{text}</option>;
	});
	
	...
}

Döredilen tegleri ulanyp, açylýan sanawy döredeliň:

return <div>
	<select value={value} onChange={event => setValue(event.target.value)}>
		{options}
	</select>
</div>;

Saýlanylan elementiniň nomerini abzasa çykaryň:

return <div>
	<select value={value} onChange={event => setValue(event.target.value)}>
		{options}
	</select>
	<p>
		siziň saýlanyşyňyz: {value}
	</p>
</div>;

Indi bolsa, onuň nomerini we tekstleriň sanawyny ulanyp, saýlanylan elementiniň tekstini çykaryň:

return <div>
	<select value={value} onChange={event => setValue(event.target.value)}>
		{options}
	</select>
	<p>
		siziň saýlanyşyňyz: {texts[value]}
	</p>
</div>;

Hemmesini bir ýere jemläp, aşakdaky kody alyň:

function App() {
	const texts = ['text1', 'text2', 'text3', 'text4'];
	const [value, setValue] = useState('');
	
	const options = texts.map((text, index) => {
		return <option key={index} value={index}>{text}</option>;
	});
	
	return <div>
		<select value={value} onChange={event => setValue(event.target.value)}>
			{options}
		</select>
		<p>
			siziň saýlanyşyňyz: {texts[value]}
		</p>
	</div>;
}
