## 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。

## en-US
|
|
|
|
Display value within it's situation with `formatter`, and we usually use `parser` at the same time.

|
```tsx
|
|
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}
