uncheck all checkboxes except the one with a class?
hi i try to check/uncheck all checkboxes that don't got a class to them. This is the code I got but it check the class boxes to.

    $(document).ready(function() {
            $('#ctl00_ContentPlaceHolder1_repReceivers_ctl00_chxAll').click(
             function() {
            if (!$("input[type='checkbox']").hasClass("testclass")) {
                 $("input[type='checkbox']").attr('checked', $('#ctl00_ContentPlaceHolder1_repReceivers_ctl00_chxAll').is(':checked'));
             }});
        });

any ideas where I go wrong?
