Question

have this fiddle and i would like to make it count the number of boxes that are selected. Now it shows the numbers of the boxes.

Any idea how to do it??

 $(function() {
    $(".selectable").selectable({
        filter: "td.cs",

        stop: function() {
            var result = $("#select-result").empty();
            var result2 = $("#result2");
            $('.ui-selecting:gt(31)').removeClass("ui-selecting");

            alert($(".ui-selected").length);
            if ($(".ui-selected").length > 4) {
                $(".ui-selected", this).each(function(i, e) {
                    if (i > 3) {
                        $(this).removeClass("ui-selected");
                    }
                });
                return;
            }

            $(".ui-selected", this).each(function() {
                var cabbage = this.id + ', ';
                result.append(cabbage);
            });

            var newInputResult = $('#select-result').text();
            newInputResult = newInputResult.substring(0, newInputResult.length - 1);
            result2.val(newInputResult);
        }
    });
});​

my problem is to show the result of maximum selected boxes allowed. for example if you select 8 boxes to show only 4 and get result of 4 that is the maximum alowed. And finaly not to be an alert, to show in div tag or similar

You can show message like this Live Demo

$('#divmsg').html($(".ui-selected").length + " box selected")
if ($(".ui-selected").length > 4) {
         $('#divmsg').html($('#divmsg').html() + ", Selection of only 4 allowed");
         $(".ui-selected").each(function(i, e) {                  
         if (i > 3) {
                        $(this).removeClass("ui-selected");
         }
        });
        return;
  }
