省市联动是典型的例子。
推荐使用 Cascader 组件。
en-US
Coordinating the selection of provinces and cities is a common use case and demonstrates how selection can be coordinated.
Using the Cascader component is strongly recommended instead as it is more flexible and capable.
import { Select } from 'antd';
const Option = Select.Option;
const provinceData = ['Zhejiang', 'Jiangsu'];
const cityData = {
Zhejiang: ['Hangzhou', 'Ningbo', 'Wenzhou'],
Jiangsu: ['Nanjing', 'Suzhou', 'Zhenjiang'],
};
class App extends React.Component {
state = {
cities: cityData[provinceData[0]],
secondCity: cityData[provinceData[0]][0],
}
handleProvinceChange = (value) => {
this.setState({
cities: cityData[value],
secondCity: cityData[value][0],
});
}
onSecondCityChange = (value) => {
this.setState({
secondCity: value,
});
}
render() {
const { cities } = this.state;
return (
<div>
<Select
defaultValue={provinceData[0]}
style={{ width: 120 }}
onChange={this.handleProvinceChange}
>
{provinceData.map(province => <Option key={province}>{province}</Option>)}
</Select>
<Select
style={{ width: 120 }}
value={this.state.secondCity}
onChange={this.onSecondCityChange}
>
{cities.map(city => <Option key={city}>{city}</Option>)}
</Select>
</div>
);
}
}
ReactDOM.render(<App />, mountNode);
