## zh-CN

这里举例如何用 `onCalendarChange` 和 `disabledDate` 来限制动态的日期区间选择。

## en-US

A example shows how to select a dynamic range by using `onCalendarChange` and `disabledDate`.

```tsx
import { DatePicker } from 'antd';
import type { Moment } from 'moment';
import React, { useState } from 'react';

const { RangePicker } = DatePicker;

type RangeValue = [Moment | null, Moment | null] | null;

const App: React.FC = () => {
  const [dates, setDates] = useState<RangeValue>(null);
  const [hackValue, setHackValue] = useState<RangeValue>(null);
  const [value, setValue] = useState<RangeValue>(null);

  const disabledDate = (current: Moment) => {
    if (!dates) {
      return false;
    }
    const tooLate = dates[0] && current.diff(dates[0], 'days') > 7;
    const tooEarly = dates[1] && dates[1].diff(current, 'days') > 7;
    return !!tooEarly || !!tooLate;
  };

  const onOpenChange = (open: boolean) => {
    if (open) {
      setHackValue([null, null]);
      setDates([null, null]);
    } else {
      setHackValue(null);
    }
  };

  return (
    <RangePicker
      value={hackValue || value}
      disabledDate={disabledDate}
      onCalendarChange={val => setDates(val)}
      onChange={val => setValue(val)}
      onOpenChange={onOpenChange}
    />
  );
};

export default App;
```
