如何在 YUI DataTable 中找到选中的行?
我正在使用带有复选框列的 YUI DataTable,如下所示:
var myColumnDefs = [
{key:"check", label:'', formatter:"checkbox"},
{other columns...}
];
如何迭代已检查的所有行?
更新:
这是我当前的解决方法:
function getCheckedIds() {
var records = yuiDataTable.getRecordSet().getRecords();
var ids = '';
for (i=0; i < records.length; i++) {
var checked = false;
if (records[i] != undefined)
{
checked = $('#' + records[i].getId() + ' td div.yui-dt-liner input.yui-dt-checkbox').attr('checked');
if (checked) {
if (ids != '') {
ids += ',';
}
ids += records[i].getData("item.id");
}
}
}
return ids;
}
I'm using a YUI DataTable with a checkbox column like this:
var myColumnDefs = [
{key:"check", label:'', formatter:"checkbox"},
{other columns...}
];
How can I iterate over all the rows that have been checked?
UPDATE:
Here is my current work-around:
function getCheckedIds() {
var records = yuiDataTable.getRecordSet().getRecords();
var ids = '';
for (i=0; i < records.length; i++) {
var checked = false;
if (records[i] != undefined)
{
checked = $('#' + records[i].getId() + ' td div.yui-dt-liner input.yui-dt-checkbox').attr('checked');
if (checked) {
if (ids != '') {
ids += ',';
}
ids += records[i].getData("item.id");
}
}
}
return ids;
}

更好的方法可能是订阅数据表的 checkboxClickEvent,然后当选中(或取消选中)复选框时,使用数据表的 selectRow/unselectRow 方法以编程方式将行标记为选中。如果这样做,它在 UI 中看起来会更好(行突出显示),并且可以使用数据表的 getSelectedRows 方法轻松获取选定的行。
A better approach might be to subscribe to the checkboxClickEvent of the Datatable, then when a check box is selected (or unselected) programmatically mark the row as selected using the selectRow/unselectRow method of the Datatable. If you do this, it looks better in the UI (the rows are highlighted) and it is easy to get the selected rows using the getSelectedRows method of the Datatable.
