<input>のonChangeで半角数字以外の入力を弾く

const [inputNum, setInputNum] = useState("");

const REGEX_NUMBER = /^[0-9]*$/g;

export const onChangeFilterNumber = (event, setterFunction) => {
    let input = event.target.value;
    if (input.match(REGEX_NUMBER)) {
        setterFunction(input);
        return true;
    } else {
        return false;
    }
};

{/* type="number"にすると"e","E"が入力できてしまう挙動になりハマった */}
<input
 type="text"
 value={inputNum}
 onChange={changeEvent => onChangeFilterNumber(changeEvent, setInputNum)}
 placeholder="半角数字で入力してください"
/>
