If I have a table like so:
如果我有一张像这样的桌子：
<table>
<thead>
<tr><th>1</th> <th>2</th> <th>3</th></tr>
</thead>
<tbody>
<tr><td>data</td> <td>checkbox</td> <td>data</td></tr>
</tbody>
</table>
When the user clicks the checkbox, I want to get the row and column indices. I can get the row index by using this code:
当用户单击复选框时，我想获取行和列索引。我可以使用以下代码获取行索引：
var row = $(this).parent().parent();
var rowIndex = $(row[0].rowIndex);
but I can't figure out the column index...
但我无法弄清楚列索引...
I tried this but it didn't work:
我试过这个，但没有用：
var colIndex = $(row.children().index(this).parent());
I looked through the results of similar questions here and it seems I have to iterate through all the tds with each or map, is there something simpler that I can use? Thanks.
我在这里查看了类似问题的结果，似乎我必须使用每个或地图遍历所有 tds，有没有更简单的东西可以使用？谢谢。

Get the index of the <td>first, since it is on the way to the <tr>:
获取第一个的索引<td>，因为它正在前往<tr>：
var cell = $(this).closest('td');
var cellIndex = cell[0].cellIndex
var row = cell.closest('tr');
var rowIndex = row[0].rowIndex;
Or using the parents()[docs]method along with a multiple-selector[docs], you could do the selection for both at once:
或者使用parents()[docs]方法和multiple-selector[docs]，您可以同时为两者进行选择：
var cellAndRow = $(this).parents('td,tr');
var cellIndex = cellAndRow[0].cellIndex
var rowIndex = cellAndRow[1].rowIndex;
