Getting the last row of a table using jQuery?

javascript, jquery

Solution

$('#yourtableid tr:last').attr('id');

Problem

I'm dynamically creating table rows. So each time I add a row, I need to get the ID of the last `<tr>` so that I can create a new `<tr>` with `ID = "(the last row's ID) + 1"`. Is there any way to get the last row's ID using jQuery?
