jQuery: how do I check if an element is the last sibling?

Question

How do I check if an element is the last sibling?

For the last cell in a row I want to perform a different action.

This doesn\'t work:

$(\'td

Here you go, but that only make sense if you want to do something to the other tds as well other wise use the last-child method described in one of the other answers.

$('td').each(function(){
    var $this = $(this);
    if ($this.index() == $this.siblings().length-1)
        {
            alert('123');
        }
})
