how to prevent shift + tab on focus out?

Question

I want to call method on Press-"TAB" but not on "Shift + Tab".

$(".txtPaymentMessage").keydown(function(e)
            {
                if(e.keyCode == 9)
                {
                    alert("You Press Tab Only");
                }
    });

Answer 1

Hope this works

$(".txtPaymentMessage").keydown(function(e)
        {
            if(e.which  == 9 && !e.shiftKey)
            {
                alert("You Press Tab Only");
            }
});
