        function datecontroller(){
                curdate = new Date(); 
                var curyear = "20"+(curdate.getYear()-100);
                var curmonth = curdate.getMonth()+1;//变量curmonth是当前的月份
                var curdate = curdate.getDate();//变量curdate是当前的日期
                if(0<curmonth && curmonth<10){
                        if(0<curdate && curdate<10){
