react使用react-sortable-hoc实现拖拽

本文主要是介绍react使用react-sortable-hoc实现拖拽，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

react-sortable-hoc拖拽

安装

 npm install react-sortable-hoc --save

代码如下（示例）：

import React, { useImperativeHandle, forwardRef, memo, useState } from 'react';import { DrawerForm } from '@ant-design/pro-form';import { message, Select ,Table} from 'antd';import { MenuOutlined } from '@ant-design/icons';import { useUpdateEffect } from 'react-use';// 核心代码import { SortableContainer, SortableElement, SortableHandle } from 'react-sortable-hoc';type ModalProps = {ref?: React.MutableRefObject<SortTrackDrawerRefObject | undefined>;onUpdated: () => void;};export type SortTrackDrawerRefObject = {openModal: () => void;};// 定义拖拽的图标const DragHandle = SortableHandle(() => <MenuOutlined style={{ cursor: 'move', color: '#999' }} />);const columns = [{title: '排序',align: 'center',dataIndex: 'sort',width: 30,className: 'drag-visible',render: () => <DragHandle />,},{title: '音频名称',dataIndex: 'name',className: 'drag-visible',},];const SortTrackDrawer: React.ForwardRefRenderFunction<SortTrackDrawerRefObject, ModalProps> = memo(forwardRef((sProps, ref) => {const [visible, setVisible] = useState<boolean>(false);// 拖拽体const SortableItem = SortableElement((props: any) => <tr {...props} />);// 拖拽容器const SortContainer = SortableContainer((props: any) => <tbody {...props} />);// 拖拽时原列表替换const arrayMoveMutable=(array: any[], fromIndex: number, toIndex: number) =>{const startIndex = fromIndex < 0 ? array.length + fromIndex : fromIndex;if (startIndex >= 0 && startIndex < array.length) {const endIndex = toIndex < 0 ? array.length + toIndex : toIndex;const [item] = array.splice(fromIndex, 1);array.splice(endIndex, 0, item);}}// 拖拽时返回新数组const arrayMoveImmutable=(array: any[], fromIndex: number, toIndex: number) =>{array = [...array];arrayMoveMutable(array, fromIndex, toIndex);return array;}// 拖拽后回调const onSortEnd = ({ oldIndex, newIndex }:{ oldIndex: number; newIndex: number }) => {if (oldIndex !== newIndex) {const newData = arrayMoveImmutable([...tableData], oldIndex,                                 newIndex).filter((el) => !!el);setTableData([...newData]);}};//  获取表格数据const getTableData = async () => {try {let res = [{name:"测试13",orderNum:1uid:1,}]setTableData(res);} finally {}};// 确定按钮返回的数据const handleFinish = async () => {const uids = tableData.map((item) => item.uid);console.log(uids)message.success('排序已更新');return true;};// 拖拽容器方法const DraggableContainer = (props: any) => (<SortContaineruseDragHandledisableAutoscrollhelperClass="row-dragging"onSortEnd={onSortEnd}{...props}/>);// 拖拽体方法const DraggableBodyRow = (props: any) => {const { className, style, ...restProps } = props;const index = tableData.findIndex((x) => x.uid === restProps['data-row-key']);return <SortableItem index={index} {...restProps} />;};// 进入组件加载数据useUpdateEffect(() => {getTableData();}, [orderType]);return (<DrawerFormwidth={isMobile ? '100%' : 520}onVisibleChange={setVisible}title={<div className="sort-track-drawer-header"><div>拖拽排序({tableData.length})</div></div>}visible={visible}onFinish={handleFinish}drawerProps={{ closable: false }}submitter={{searchConfig: {submitText: '保存排序',resetText: '取消',},}}><Tablepagination={false}dataSource={tableData}columns={columns as any}rowKey="uid"size="small"showHeader={false}loading={loading}components={{body: {wrapper: DraggableContainer,row: DraggableBodyRow,},}}/></DrawerForm>);}),);export default SortTrackDrawer;

效果如图：
