用antd select做一个级联选择器

好的，下面是一个antd select级联选择器的示例代码：

import React, { useState } from 'react';
import { Select } from 'antd';

const { Option } = Select;

const CascaderSelect = () => {
  const [cities, setCities] = useState([]);
  const [regions, setRegions] = useState([]);

  const handleCountryChange = (value) => {
    setCities([]);
    setRegions([]);
    // 根据选中的国家，设置城市选项
    if (value === 'china') {
      setCities(['beijing', 'shanghai', 'guangzhou']);
    } else if (value === 'usa') {
      setCities(['new york', 'washington', 'los angeles']);
    } else if (value === 'japan') {
      setCities(['tokyo', 'osaka', 'kyoto']);
    }
  }

  const handleCityChange = (value) => {
    setRegions([]);
    // 根据选中的城市，设置地区选项
    if (value === 'beijing') {
      setRegions(['haidian', 'chaoyang', 'dongcheng']);
    } else if (value === 'shanghai') {
      setRegions(['pudong', 'minhang', 'xuhui']);
    } else if (value === 'guangzhou') {
      setRegions(['yuexiu', 'tianhe', 'haizhu']);
    } else if (value === 'new york') {
      setRegions(['manhattan', 'brooklyn', 'queens']);
    } else if (value === 'washington') {
      setRegions(['northwest', 'northeast', 'southeast']);
    } else if (value === 'los angeles') {
      setRegions(['hollywood', 'beverly hills', 'santa monica']);
    } else if (value === 'tokyo') {
      setRegions(['shibuya', 'shinjuku', 'harajuku']);
    } else if (value === 'osaka') {
      setRegions(['umeda', 'namba', 'tennoji']);
    } else if (value === 'kyoto') {
      setRegions(['higashiyama', 'nakagyo', 'shimogyo']);
    }
  }

  return (
    <div>
      <Select style={{ width: 200 }} onChange={handleCountryChange}>
        <Option value="china">China</Option>
        <Option value="usa">USA</Option>
        <Option value="japan">Japan</Option>
      </Select>
      <Select style={{ width: 200, marginLeft: 10 }} onChange={handleCityChange}>
        {cities.map(city => (
          <Option key={city} value={city}>{city}</Option>
        ))}
      </Select>
      <Select style={{ width: 200, marginLeft: 10 }}>
        {regions.map(region => (
          <Option key={region} value={region}>{region}</Option>
        ))}
      </Select>
    </div>
  );
}

export default CascaderSelect;

这个示例代码中，我们使用了React的useState Hook来管理组件的状态，根据选中的国家和城市设置城市和地区选项。在Select组件中，我们使用了antd的Option组件来设置选项，onChange事件用来处理选项的变化，根据选中的值来动态更新组件的状态。
