Question

What I want is, when i use the tab key on the last list select menu I want to get an alert. With the jquery i’ve got I will get an alert but on every select menu instead of only the last.

HTML markup

<div id="invoiceLinesForm" style="">

        $(this).blur(function(e)
        {
            if($(this).parent().parent().is('li:last'))
            {
                alert('last item');
            }

            e.preventDefault();
            e.stopImmediatePropagation();

        });                 
    }
