[jQuery] Problem with parent('td').parent('tr').$('td').length

[jQuery] Problem with parent('td').parent('tr').$('td').length


Hello,
I have HTML code like this:
<table>
<tr>
<td>
</td>
<td>
<input id="inp">
</td>
<td>
</td>
</tr>
</table>
I want to know have many table cells are in the row and have to start querying from the input element.
When I query $("#inp").parent("td").parent("tr").$("td").length it fails with the message:
$("#inp").parent("td").parent("tr").$ is not a function
The following queries do work:
$("#inp").parent("td").parent("tr").length
$("td").length
Any ideas or other ways to get this working?
Regards,
Emil Zegers
