rsuite library return the value directly in the onChange function.
So, instead:
onChange={e=>{setuser(e.target.value)}}
You should write
onChange={value=>{setuser(value)}}
This is a class that I have written with rsuite / bootstrap and basic input. You can see the difference and copy/paste the part that you want.
import React, { useState } from 'react';
import { InputGroup, Input } from 'rsuite';
import InputGroupBoostrap from 'react-bootstrap/InputGroup';
import FormControlBoostrap from 'react-bootstrap/FormControl';
const Question2 = () => {
const [user, setUser] = useState('example');
return (
<>
{/* rsuite */}
<InputGroupBoostrap>
<Input type='text' value={user} onChange={value=>{ setUser(value)}} id="user"/>
<InputGroup.Button>
Button
</InputGroup.Button>
{/* Bootstrap */}
</InputGroupBoostrap>
<InputGroupBoostrap>
<InputGroupBoostrap.Text>User 1</InputGroupBoostrap.Text>
<FormControlBoostrap value={user} onChange={(e) => { setUser(e.target.value); }} placeholder="user" />
</InputGroupBoostrap>
{/* input */}
<div>
<span>User 2</span>
<input value={user} onChange={(e) => { setUser(e.target.value); }}/>
</div>
</>
);
}
export default Question2;
I hope I've helped
