TypeScript 中将 any 类型转换为具体类型 - 地址组件示例

export default function Address(props: {onChange: Function, value: string}) { const { onChange, value } = props; const [area,setArea] = useState<Array>([]) const handleOnChange = (value: Array) => { setArea(value); if (onChange) { onChange(value.join(' ')); } }; return ( <Input addonBefore={ <Cascader style={{ width: 'auto', textAlign: 'left' }} options={dataAll} allowClear placeholder='请选择省市区/县' onChange={handleOnChange} value={area} /> } onChange={(e) => onChange(e.target.value)} value={value} /> ); }
