$("#hdPeriod").val(data.Guid);
document.forms[0].submit();

function changeURLArg(url, arg, arg_val) {
            var pattern = arg + ‘=([^&]*)‘;
            var replaceText = arg + ‘=‘ + arg_val;
            if (url.match(pattern)) {
                var tmp = ‘/(‘ + arg + ‘=)([^&]*)/gi‘;
                tmp = url.replace(eval(tmp), replaceText);
                return tmp;
            } else {
                if (url.match(‘[\?]‘)) {
                    return url + ‘&‘ + replaceText;
                } else {
                    return url + ‘?‘ + replaceText;
                }
            }
        }

       $("#hdPeriod").val(data.Guid);
       window.location.href = changeURLArg(window.location.href, ‘period‘, data.Guid)
