$('#PbtnSubmit').click(function(event) {
            $('#PricingEditExceptions input[name=PMchk]').each(function() {
                if ($("#PricingEditExceptions input:checkbox:checked").length > 0) {
                    var checked = $('#PricingEditExceptions input[type=checkbox]:checked');
                    var PMstrIDs = checked.map(function() {
                        return $(this).val();
                    }).get().join(',');
                    $('#1_exceptiontypes').attr('value', exceptiontypes)
                    $('#1_PMstrIDs').attr('value', PMstrIDs);
                } else {
                    alert("Please select atleast one exception");
                    event.preventDefault();
                }
            });
        });

I am sending exceptiondis to the Controler to handle the update.. this is my Begin form..

<script type="text/javascript">
    var exceptiontypes = $.cookie("exceptiontype");
</script>
<% using (Html.BeginForm("MassUpdate", "Pricing", FormMethod.Post, new { @id = "exc-"})) 
   { %>
    <input type="hidden" id="exceptiontypes" runat="server" />
    <input type="hidden" id="PMstrIDs" value="" runat="server"/>
<%= Html.ValidationSummary(true)%>

I am retreving the ExceptionId;s controler side is like this..

var exceptionIds = Request.Form[1].Split(','); var exceptiontype = Request.Form[0];

how ever this is working in firefox not in IE8.. Ie8 I am getting only Frist ExcdptionId not all checkbox exceptions ids;

thanks
