Capturing "Delete" Keypress with jQuery

Javascript Keycodes

• e.keyCode == 8 for backspace
• e.keyCode == 46 for forward backspace or delete button in PC's

^{Except this detail Colin & Tod's answer is working.}

$('html').keyup(function(e){
    if(e.keyCode == 46) {
        alert('Delete key released');
    }
});

You shouldn't use the keypress event, but the keyup or keydown event because the keypress event is intended for real (printable) characters. keydown is handled at a lower level so it will capture all nonprinting keys like delete and enter.
