我正在尝试将 react-virtualized 实现到我的项目中。我有一个带有细分列表的侧面板。当用户选择一个项目时,我希望有一个类似手风琴的功能。当页面首次加载时,它看起来工作正常。
然而,当我开始向下滚动列表看起来像这样
这是代码
const mapStateToProps = state => ({
windowHeight: state.dimensions.windowHeight,
sbds: new Immutable.List(state.sbds.data),
sbd: state.sbd.data
})
@connect(mapStateToProps)
export default class SBD extends Component {
static propTypes = {
windowHeight: PropTypes.number,
sbds: PropTypes.instanceOf(Immutable.List),
sbd: PropTypes.object
}
constructor(props) {
super(props)
this.state = {
listHeight: props.windowHeight - 250,
listRowHeight: 60,
overscanRowCount: 10,
rowCount: props.sbds.size,
scrollToIndex: undefined,
collapse: true
}
}
componentWillUnmount() {
}
shouldComponentUpdate(nextProps, nextState) {
const {sbds} = this.props
if (shallowCompare(this, nextProps, nextState))
return true
else return stringify(sbds) !== stringify(nextProps.sbds)
}
_handleSelectRow = selected => {
sbdRequest(selected)
const obj = {[selected.id]: true}
this.setState(obj)
}
render() {
const {
listHeight,
listRowHeight,
overscanRowCount,
rowCount,
scrollToIndex
} = this.state
return (
<div>
<SearchGroup />
<Card className='border-0 mt-10 mb-0'>
<CardBlock className='p-0'>
<AutoSizer disableHeight>
{({width}) => (
<List
ref='List'
className=''
height={listHeight}
overscanRowCount={overscanRowCount}
rowCount={rowCount}
rowHeight={listRowHeight}
rowRenderer={this._rowRenderer}
scrollToIndex={scrollToIndex}
width={width}
/>
)}
</AutoSizer>
</CardBlock>
</Card>
</div>
)
}
_getDatum = index => {
const {sbds} = this.props
return sbds.get(index % sbds.size)
}
_rowRenderer = ({index}) => {
const {sbd} = this.props
const datum = this._getDatum(index)
return (
<span key={datum.id}>
<Button
type='button'
color='link'
block
onClick={() => this._handleSelectRow(datum)}>
{datum.name}
</Button>
<Collapse isOpen={this.state[datum.id]}>
<Card>
<CardBlock>
FOO BAR
</CardBlock>
</Card>
</Collapse>
</span>
)
}
}
