Pur*_*Oza 5 sorting reactjs material-ui
我在我的 React 项目中使用 Material UI 的 Table 组件。我有多个列,其中包括该日期添加的记录。如何根据添加记录的日期对表格进行排序?我正在接收 UNIX 时间戳并将其转换为 mm/dd/yyyy 格式以方便阅读。
我正在使用 Materila -ui Table 组件: https: //material-ui.com/demos/tables/
我尝试将日期数组传递给排序函数,但它没有成功,因为它期望包含所有列的数组。
预期的行为是,当我单击添加日期列附近的排序图标时,它应该根据添加日期对表进行升序或降序排序。
function desc(a, b, orderBy) {
console.log(a.addedDate)
if (b.addedDate < a.addedDate) {
console.log(b.addedDate)
return -1;
}
if (b.addedDate > a.addedDate) {
return 1;
}
return 0;
}
function stableSort(array, cmp) {
const stabilizedThis = array.map((el, index) => [el, index]);
stabilizedThis.sort((a, b) => {
const order = cmp(a[0], b[0]);
if (order !== 0) return order;
return a[1] - b[1];
});
return stabilizedThis.map(el => el[0]);
}
function getSorting(order, orderBy) {
return order === 'desc' ? (a, b) => desc(a, b, orderBy) : (a, b) =>
-desc(a, b, orderBy);
}
const rows = [
{ id: 'id', numeric: false, label: 'ID'},
{ id: 'lastname', numeric: true, label: 'lastname' },
{ id: 'firstname', numeric: true, label:'firstname' },
{ id: 'email', numeric: true, label: 'email'},
{ id: 'dateadded', numeric: true, label: 'dateadded' }
];
class EnhancedTableHead extends React.Component {
createSortHandler = property => event => {
this.props.onRequestSort(event, property);
};
render() {
const { onSelectAllClick, order, orderBy, numSelected, rowCount }
= this.props;
return (
<TableHead>
<TableRow>
<TableCell padding="checkbox">
<Checkbox
indeterminate={numSelected > 0 && numSelected < rowCount}
checked={numSelected === rowCount}
onChange={onSelectAllClick}
/>
</TableCell>
{rows.map(
row => (
<TableCell
key={row.id}
align={row.numeric ? 'right' : 'left'}
padding={row.disablePadding ? 'none' : 'default'}
sortDirection={orderBy === row.id ? order : false}
>
<Tooltip
title="Sort"
placement={row.numeric ? 'bottom-end' : 'bottom-start'}
enterDelay={300}
>
<TableSortLabel
active={orderBy === row.id}
direction={order}
onClick={this.createSortHandler(row.id)}
>
{row.label}
</TableSortLabel>
</Tooltip>
</TableCell>
),
this,
)}
</TableRow>
</TableHead>
);
}
}
My Table Body looks like following:
<TableBody>
{stableSort(data, getSorting(order, orderBy).slice(page* rowsPerPage, page * rowsPerPage + rowsPerPage)
.map(n => {
var convertedTimeStamp;
var d = new Date(n.addedDate);
convertedTimeStamp = d.toLocaleDateString();
if (n.nuid.indexOf(this.state.filterText) === -1 ) {
return;
}
return (
<TableRow
hover
tabIndex={-1}
key={n.id}
>
<TableCell padding="checkbox">
</TableCell>
<TableCell component="th" scope="row" padding="none">
{n.id}
</TableCell>
<TableCell align="left">{n.lastName}</TableCell>
<TableCell align="left">{n.firstName}</TableCell>
<TableCell align="left">{n.email}</TableCell>
<TableCell align="right">{convertedTimeStamp} .
</TableCell>
</TableRow>
);
})}
</TableBody>
