Question

hey guys,
i have a form that can be influenced with up and down keys.

without that code it’s just a normal input-search field that fires a normal action. however i wonder how i can stop the default behaviour when i change the value of the input field with the Up and Down arrow keys.

check out this: http://jsfiddle.net/3UHVY/7

I only want the alert to happen if I change the value of the box with the up and down keys, otherwise no alert should be fired and the form should be submitted normally. However if the input-value is changed via the arrow keys JUST THE ALERT should be fired and the form should not be submitted.

any idea how to solve that?

var ok=0;
$(window).keydown(function(e) {

$('.s').focus(); 
switch ( e.keyCode ) {
case 38: // Up
    $('.s').val('Up pressed');
    ok=1;
    break;
case 40: // Down
    $('.s').val('Down pressed'); 
    ok=1;
    break;
case 13: // Enter
    if(ok)
    alert($('.s').val());
    break;
default:
ok=0;
break;
}
});
