将 TextField 值存储在 MaterialUI/React 的变量中

Question

I have a TextField and would like to take the input and store it in a variable.

<TextField
  id="output_elevator-amount"
  label="Elevator amount"
  color="primary"
  // variant="outlined"
  type="number"
  InputLabelProps={{
    shrink: true
  }}
  InputProps={{
    readOnly: true
  }}
  onChange={(event) => {
    setAmount(parseInt(event.target.value));
  }}
/>

When I was working with javascript and html I did something like this but now with typescript/MUI/React I'm not sure what to do.

let elevatorAmt = (document.getElementById('output_elevator-amount') as HTMLInputElement);

any help is greatly appreciated.

Answer 1

If you want to store "somewhere" the variable inputed via onChange, you are already doing by setting setAmount .

I am assuming you are using this [amount, setAmount] = useState('') . Try console logging amount and use it where you need.
