[jQuery] Re: Looping through all unchecked checkboxes - how to do it?

[Karl Swedberg]

Hi Brett, this should do it.

$(':checkbox').each(function() {
   this.disabled = +this.value > diff;
});

I have a function which is executed whenever someone clicks a checkbox
on the page.  There are lots of checkboxes on the page.  I want the
function to be performed on only the unchecked boxes.  I've tried this
two ways, neither of which has worked.  Here are the two methods I've
tried.

Method #1
$(".item input:unchecked").each(
    function() {
         if ($(this).val() > diff) {
                $(this).attr('disabled', true);
          } else {
                $(this).removeAttr('disabled');
         }
    }
);

Method #2
$(".item input").each(
    function() {
         if ($(this).is(":unchecked")) {
                if ($(this).val() > diff) {
                        $(this).attr('disabled', true);
                } else {
                        $(this).removeAttr('disabled');
                }
           }
    }
);

Where diff is an integer and the values of the checkboxes are all
integers.  The problem is the function ends up getting run on all
checkboxes, even boxes that have been checked.

Is there another way to do this?  Something I'm missing.

Thanks,
