What Is The Best Way To Select Option When Option Is An Object?
What is the best way to select option when option is an object?
During changing selected value I need to get selected option object
example https://codesandbox.io/s/st-of-select-object-ssib9
function App() {
const [value, setValue] = useState(options[0]);
return (
<select
value={value}
onChange={event => {
setValue(event.target.value);
}}
>
{options.map(option => {
return <option value={option}>{option.label}</option>;
})}
</select>
);
}

Answer
I think you want the state to be an object and not the select's value, if so then try the following:
const [option, setOption] = useState(options[0]);
function handleChange(event) {
const { value } = event.target;
const option = options.find(o => o.value === parseInt(value, 10));
if(option)
setOption(option); // object
}
...
<select
value={option.value}
onChange={handleChange}
>
{options.map(option => <option key={option.value} value={option.value}>{option.label}</option>)}
</select>
