ant design中实现table的表格行的拖拽
前言:
首先刚开始知道要书写一个这样的功能我的内心是比较崩溃的 完全没有思路, 然后就打开官网的文档进行观看。一开始准备写 打开官网的一个文档是4.0的 看起来也是一脸的蒙蔽,接着找到3的一个文档,接下来直接说说如何让实现当前这个功能上代码
代码部分:
import { Table } from 'antd'; import { DndProvider, DragSource, DropTarget } from 'react-dnd'; import { HTML5Backend } from 'react-dnd-html5-backend'; import update from 'immutability-helper'; let dragingIndex = -1; class BodyRow extends React.Component { render() { const { isOver, connectDragSource, connectDropTarget, moveRow, ...restProps } = this.props; const style = { ...restProps.style, cursor: 'move' }; let { className } = restProps; if (isOver) { if (restProps.index > dragingIndex) { className += ' drop-over-downward'; } if (restProps.index < dragingIndex) { className += ' drop-over-upward'; } } return connectDragSource( connectDropTarget(<tr {...restProps} className={className} style={style} />), ); } } const rowSource = { beginDrag(props) { dragingIndex = props.index; return { index: props.index, }; }, }; const rowTarget = { drop(props, monitor) { const dragIndex = monitor.getItem().index; const hoverIndex = props.index; // Don't replace items with themselves if (dragIndex === hoverIndex) { return; } // Time to actually perform the action props.moveRow(dragIndex, hoverIndex); // Note: we're mutating the monitor item here! // Generally it's better to avoid mutations, // but it's good here for the sake of performance // to avoid expensive index searches. monitor.getItem().index = hoverIndex; }, }; const DragableBodyRow = DropTarget('row', rowTarget, (connect, monitor) => ({ connectDropTarget: connect.dropTarget(), isOver: monitor.isOver(), }))( DragSource('row', rowSource, connect => ({ connectDragSource: connect.dragSource(), }))(BodyRow), ); const columns = [ { title: 'Name', dataIndex: 'name', key: 'name', }, { title: 'Age', dataIndex: 'age', key: 'age', }, { title: 'Address', dataIndex: 'address', key: 'address', }, ]; class DragSortingTable extends React.Component { state = { data: [ { key: '1', name: 'John Brown', age: 32, address: 'New York No. 1 Lake Park', }, { key: '2', name: 'Jim Green', age: 42, address: 'London No. 1 Lake Park', }, { key: '3', name: 'Joe Black', age: 32, address: 'Sidney No. 1 Lake Park', }, ], }; components = { body: { row: DragableBodyRow, }, }; moveRow = (dragIndex, hoverIndex) => { const { data } = this.state; const dragRow = data[dragIndex]; this.setState( update(this.state, { data: { $splice: [[dragIndex, 1], [hoverIndex, 0, dragRow]], }, }), ); }; render() { return ( <DndProvider backend={HTML5Backend}> <Table columns={columns} dataSource={this.state.data} components={this.components} onRow={(record, index) => ({ index, moveRow: this.moveRow, })} /> </DndProvider> ); } } ReactDOM.render(<DragSortingTable />, mountNode); #components-table-demo-drag-sorting tr.drop-over-downward td { border-bottom: 2px dashed #1890ff; } #components-table-demo-drag-sorting tr.drop-over-upward td { border-top: 2px dashed #1890ff; }
这是官网的示例 ,那么我们如何实现呢?
第一步 引入第一个类
第二步 找准数据
第三步 进行数据的一个赋值我这边是dva.js赋值
第四步 回调或者确定按钮处理数据(这边是确定按钮处理值然后调接口)
总结:
这样的话 表格行就可以进行拖拽操作了
