How can I store and update multiple values in React useState?

I’ve a series of user data elements which I’m collecting inside a React component using hooks.

const [mobile, setMobile] = useState('');
const [username, setUsername] = useState('');
const [email, setEmail] = useState('');
const [password, setPassword] = useState('');
const [confirmPassword, setConfirmPassword] = useState('');

Each of these are updated as follows.

<input type="text"
       className="form-control"
       id="mobile"
       placeholder="Enter a valid mobile number"
       onChange={event => {setMobile(event.target.value)}}/>

Is there a more succint way to do this using an object as the variable?

Answer

You should add name attributes to input tags. Each name must refer to key in AllValues object.

const [allValues, setAllValues] = useState({
   mobile: '',
   username: '',
   email: '',
   password: '',
   confirmPassword: ''
});
const changeHandler = e => {
   setAllValues({...allValues, [e.target.name]: e.target.value})
}
return (
   <input type="text"
       className="form-control"
       id="mobile"
       name="mobile"
       placeholder="Enter a valid mobile number"
       onChange={changeHandler}
   />
   // ...
)
