Jquery how to count checked and disable checkboxes

Question

I am trying to disable all unchecked checkboxes when there are 5 checked checkboxes.

My code is not working here it is: http://jsfiddle.net/mtYtW/18/

My Jquery:

Answer 1

$(':checkbox').bind('click', function(){
    if($(':checkbox:checked').length >= 5) {
        $(':checkbox').not(':checked').prop('disabled', true);
    } else {
        $(':checkbox').not(':checked').prop('disabled', false);
    }
});

Note that prop is jQuery 1.6 exclusive. In case of jQuery < 1.6 use attr.
