import { Select, Space, Divider, Button } from 'antd';export default function AllSelect (props) {const {fieldNames, // 自定义节点labbel、value、options、grouLabeloptions, // 数据化配置选项内容，{label,value}[]value, // 指定当前选中的条目，多选时为一个数组onChange, // 选中option或input的value变化时...restProps} = props;// console.log('AllSelect', mode);const [selectValue, setSelectValue] = useState([]);const [isShowAll, setIsShowAll] = useState(false);const selectAll = () => {let values = options.map(option => {return fieldNames.value? option[fieldNames.value]: option.value || option;});setSelectValue(values);onChange(values);};const clearAll = () => {setSelectValue([]);onChange([]);};// 选中option或input的value变化时const handleChange = (values, option) => {console.log('handleChange', values);setSelectValue(values);onChange(values);};// 页面加载完成时调用useEffect(() => {if (props.mode) {setIsShowAll(true);} else {setIsShowAll(false);}}, []);return (<Selectplaceholder='请选择'fieldNames={fieldNames}value={selectValue}options={options}onChange={handleChange}dropdownRender={menu => (<>{menu}{isShowAll ? (<><Divider style={{ margin: '8px 0' }} /><Space><Button type='link' onClick={selectAll}>全选</Button><Button type='link' onClick={clearAll}>清空</Button></Space></>) : ('')}</>)}{...restProps}></Select>);
