Hi,
There is a div I want to do here.
If two checkboxes are checked, I will show the div. If 1 is not checked, I will give an alert.
<script>
    $(function () {
        $('#formopen').click(function ()
        {
            var checks = $("#chk1, #chk2");
            checks.click(function ()
            {
                if (checks.filter(':checked').length == checks.length)
                {
                    $('#formopen').hide();
                }
                else
                {
                    $('#formopen').show();
                }
            });
            alert("Accept form.!!");
        });
    });
</script>
