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').each(function(){     var $this = $(this);     if ( $this === $this.parent().last('td') )         {             alert('123');         } }) 

And neither does it if I remove .parent().

This is more elegant and worked for me:

if($(this).is(':last-child')) {     alert('123'); }
