jQuery :last-child selector

Question

How do I add class="x" to the last table cell that's on the same row as the one that has class="insert"? Something like:

$('td.insert').parents('tr').(':last-child').addClass('x');

Answer 1

$('td.insert').siblings(':last-child').addClass('x');

Answer 2

You can do that like this:

$('td.insert').siblings(':last-child').addClass('x');

This filters the sibling cells, leaving only the last child to add the class to.
