zh-CN

通过 formatter 格式化数字，以展示具有具体含义的数据，往往需要配合 parser 一起使用。

这里有一个更复杂的货币格式化输入框：https://codesandbox.io/s/currency-wrapper-antd-input-3ynzo

en-US

Display value within it's situation with formatter, and we usually use parser at the same time.

Here is a Intl.NumberFormat InputNumber implementation: https://codesandbox.io/s/currency-wrapper-antd-input-3ynzo

import { InputNumber, Space } from 'antd';
import React from 'react';

const onChange = (value: number | string) => {
  console.log('changed', value);
};

const App: React.FC = () => (
  <Space>
    <InputNumber
      defaultValue={1000}
      formatter={value => `$ ${value}`.replace(/\B(?=(\d{3})+(?!\d))/g, ',')}
      parser={value => value!.replace(/\$\s?|(,*)/g, '')}
      onChange={onChange}
    />
    <InputNumber
      defaultValue={100}
      min={0}
      max={100}
      formatter={value => `${value}%`}
      parser={value => value!.replace('%', '')}
      onChange={onChange}
    />
  </Space>
);

export default App;
