这是我的第一个问题,我只需要了解为什么在处理传递给react-table useTable钩子的Checkbox中的更改时为什么无法访问组件的实际状态。
const {
getTableProps,
getTableBodyProps,
headerGroups,
rows,
prepareRow,
}: ITableInstance = useTable(
{
columns: tableColumns,
data,
},
useRowSelect,
(hooks: Hooks<any>) => {
hooks.visibleColumns.push((tableColumns) => [
{
id: 'selection',
Header: (headerCell: THeaderProps) => (
<Checkbox
{...headerCell.getToggleAllRowsSelectedProps()}
onChange={handleSelectAllRows(headerCell)}
/>
),
Cell: ({row}: TCellProps) => (
<Checkbox
{...row.getToggleRowSelectedProps()}
onChange={() => handleSelect((row.original as TSelectableTableRowData).selectionValue)}
/>
),
},
...tableColumns,
]);
}
);
这是我的Table组件状态和更改时的回调:
const [selected, setSelected] = React.useState<string[]>([]);
const handleSelect = (selectedValue: string) => {
setSelected(selected.concat([selectedValue])); // When I reach here, state is always = [], but it must have one item, when I check second checkbox.
};
似乎每个复选框事件处理程序都使用其自己的反应状态。有什么想法为什么会那样吗?谢谢!
