I want to delete a row in table which lay another table's td. like this:

<table id="tb1">

<tr id="tr1">

<td>

<table id="tb2">

<tr id="tr2">

<td><input type="button" onclick="delel(this)" value="delete"/></td>

</tr>

</td>

</tr>

</table>

<script type="text/javascript">

function delel(ele) {

I want to delete <tr id="tr2">...

But infact, <tr id="tr1"... was deleted.

//how to resolve it?

$(ele).parents("tr").remove();

}

</script>

Use closest

$(this).closest("tr").remove();
