keypress, keydown, keyup value of input box AFTER event

Question

$("#last_4_cc").keyup(function()
{
    $.post('<?php echo site_url("sales/set_last_4_cc");?>', {last_4_cc: $('#last_4_cc').val()});    
});

When doing keypress() or keydown() I get the value before the key is inputed, when I do key up, I get the val() for the after the key is inputed.

Example:

Cur Value: 333

keyPress "3" Cur Val 333

Cur Value: 333

keyUp "3" Cur Val 3333

Why is this?

Answer 1

This is the expected behavior? KeyPress and KeyDown events are supposed to be triggered before the default action is performed, KeyUp fires afterwards.
