使用react-sortable-hoc实现拖拽
如图:
提示:下面案例可供参考
1.文件1
代码如下(示例):文件名称:./dragcomponents
import * as React from 'react'import { sortableContainer, sortableElement, sortableHandle,} from "react-sortable-hoc"; // 拖拽的关键组件const Sortable: React.FC = (props) => { const { dataSource = [], ComSortItem, sortEnd } = props; // 拖拽时原列表替换 function arrayMoveMutable(array, fromIndex, toIndex) { const startIndex = fromIndex = 0 && startIndex < array.length) { const endIndex = toIndex { return {children}; }); // 拖拽ico const DragHandle = sortableHandle((value1, sortIndex1) => ( )); function handleDelete(index) { const List = [...dataSource]; List.splice(index, 1) sortEnd(List); } // 数据更新 function updateData(val, index) { const List = [...dataSource]; List[index] = val; sortEnd(List); } // 拖拽体 const SortableItem = sortableElement(({ value, sortIndex }) => { return ( // // // ); }); // 拖拽后回调 const onSortEnd = ({ oldIndex, newIndex }) => { const List = arrayMoveImmutable(dataSource, oldIndex, newIndex); sortEnd(List); }; return ( {dataSource.length > 0 && dataSource.map((value, index) => ( ))} );}export default Sortable;
2.文件2
代码如下(示例):文件名称’./usedrag’
import * as React from 'react'import { Checkbox } from 'antd'import Sortable from './dragcomponents'import './index.scss'const _ = require('lodash')import store from './store'import { SAVE_RENDER_ALL_DATA } from './actionType'const Usedrag: React.FC = (props) => { const { state, dispatch } = React.useContext(store); // 自定义拖拽体 const {upDateRenderData} = props const showdata ={...props.renderData} function AddForm(showdata) { return ({showdata.data.valuedata.fieldName} 控件标签显示名称{showdata.data.valuedata.labelName} 所占列宽{showdata.data.valuedata.span} {/* */} ) } const updateSource = (val) => { const arrdata: any = _.cloneDeep(props.renderData) const arr: any = _.cloneDeep(val) if(JSON.stringify(arrdata) !== JSON.stringify(arr)){ for (let i = 0; i <= arr.length - 1; i++) { arr[i].edit = 1; } } // upDateRenderData(arr) dispatch({ type: SAVE_RENDER_ALL_DATA, value: arr }) } return ( } sortEnd={(val) => { updateSource(val) }} /> );};export default Usedrag3.使用
代码如下(示例):
import Usedrag from './usedrag';到此这篇关于react拖拽组件react-sortable-hoc的使用的文章就介绍到这了,更多相关react拖拽组件react-sortable-hoc内容请搜索脚本之家以前的文章或继续浏览下面的相关文章希望大家以后多多支持脚本之家!
