                var rdsObj = document.getElementsByName(className);
                var chackVal = null;
                for(i = 0; i < rdsObj.length; i++) {
                    if (rdsObj[i].checked) {
                        chackVal = rdsObj[i].value;
                    }
                }
                return chackVal;
