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 {
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
}
sortEnd={(val) => {
updateSource(val)
}}
/>
sortEnd={(val) => {
updateSource(val)
}}
/>
