我正在尝试在我的项目中使用React Data Grid,我想使用行拖放和拖动列重新排序功能。
我尝试通过传递draggable: true
ReactDataGrid列属性并使用DraggableHeader.DraggableContainer包装ReactDataGrid和Draggable.Container来实现此目的。
它使列标题可移动,但它不会在DraggableContainer中触发onHeaderDrop操作,并且它给出了控制台错误Uncaught TypeError: Cannot read property 'id' of undefined
。
我根据上述说明更改example23-row-reordering.js。
const ReactDataGrid = require('react-data-grid');
const exampleWrapper = require('../components/exampleWrapper');
const React = require('react');
const {
Draggable: { Container, RowActionsCell, DropTargetRowContainer },
Data: { Selectors },
DraggableHeader: {DraggableContainer}
} = require('react-data-grid-addons');
import PropTypes from 'prop-types';
const RowRenderer = DropTargetRowContainer(ReactDataGrid.Row);
class Example extends React.Component {
static propTypes = {
rowKey: PropTypes.string.isRequired
};
static defaultProps = { rowKey: 'id' };
constructor(props, context) {
super(props, context);
this._columns = [
{
key: 'id',
name: 'ID',
draggable: true
},
{
key: 'task',
name: 'Title',
draggable: true
},
{
key: 'priority',
name: 'Priority',
draggable: true
},
{
key: 'issueType',
name: 'Issue Type',
draggable: true
}
];
this.state = { rows: this.createRows(1000), selectedIds: [1, 2] };
}
getRandomDate = (start, end) => {
return new Date(start.getTime() + Math.random() * (end.getTime() - start.getTime())).toLocaleDateString();
};
createRows = (numberOfRows) => {
let rows = [];
for (let i = 1; i < numberOfRows; i++) {
rows.push({
id: i,
task: 'Task ' + i,
complete: Math.min(100, Math.round(Math.random() * 110)),
priority: ['Critical', 'High', 'Medium', 'Low'][Math.floor((Math.random() * 3) + 1)],
issueType: ['Bug', 'Improvement', 'Epic', 'Story'][Math.floor((Math.random() * 3) + 1)],
startDate: this.getRandomDate(new Date(2015, 3, 1), new Date()),
completeDate: this.getRandomDate(new Date(), new Date(2016, 0, 1))
});
}
return rows;
};
rowGetter = (i) => {
return this.state.rows[i];
};
isDraggedRowSelected = (selectedRows, rowDragSource) => {
if (selectedRows && selectedRows.length > 0) {
let key = this.props.rowKey;
return selectedRows.filter(r => r[key] === rowDragSource.data[key]).length > 0;
}
return false;
};
reorderRows = (e) => {
let selectedRows = Selectors.getSelectedRowsByKey({rowKey: this.props.rowKey, selectedKeys: this.state.selectedIds, rows: this.state.rows});
let draggedRows = this.isDraggedRowSelected(selectedRows, e.rowSource) ? selectedRows : [e.rowSource.data];
let undraggedRows = this.state.rows.filter(function(r) {
return draggedRows.indexOf(r) === -1;
});
let args = [e.rowTarget.idx, 0].concat(draggedRows);
Array.prototype.splice.apply(undraggedRows, args);
this.setState({rows: undraggedRows});
};
onRowsSelected = (rows) => {
this.setState({selectedIds: this.state.selectedIds.concat(rows.map(r => r.row[this.props.rowKey]))});
};
onRowsDeselected = (rows) => {
let rowIds = rows.map(r => r.row[this.props.rowKey]);
this.setState({selectedIds: this.state.selectedIds.filter(i => rowIds.indexOf(i) === -1 )});
};
render() {
return (
<DraggableContainer
onHeaderDrop={()=>{console.log('column dropped');}}
>
<Container>
<ReactDataGrid
enableCellSelection={true}
rowActionsCell={RowActionsCell}
columns={this._columns}
rowGetter={this.rowGetter}
rowsCount={this.state.rows.length}
minHeight={500}
rowRenderer={<RowRenderer onRowDrop={this.reorderRows}/>}
rowSelection={{
showCheckbox: true,
enableShiftSelect: true,
onRowsSelected: this.onRowsSelected,
onRowsDeselected: this.onRowsDeselected,
selectBy: {
keys: {rowKey: this.props.rowKey, values: this.state.selectedIds}
}
}}/>
</Container>
</DraggableContainer>);
}
}
module.exports = exampleWrapper({
WrappedComponent: Example,
exampleName: 'Row Reordering',
exampleDescription: 'This examples demonstrates how single or multiple rows can be dragged to a different positions using components from Draggable React Addons',
examplePath: './scripts/example23-row-reordering.js'
});

我查看了他们的文档,但找不到他们说这两个功能无法一起使用的地方。但是在他们的示例中没有为此提供任何示例。文档的任何示例代码描述了如何将这两个功能结合使用将非常感激。
