Question

I am having problem using variables as selectors with jquery.

how do I select last td using $t?

<table id="mytable">
<tr>
<td>a</td>
<td>b</td>
</tr>
</table>

var $t = $(‘#mytable’)

Answer 1

Use .find and combine with :last. This way you search the table for the last td

$t.find("td:last")

From jQuery docs:

.find

Description: Get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.

:last

Description: Selects the last matched element.

Note that :last selects a single element by filtering the current jQuery collection and matching the last element within it.
