DOM:时间对象的使用

            function time(){
                var dt=new Date();
                
                var year=dt.getFullYear();
//获取月份0~11
                var moth=dt.getMonth()+1;
                
                var day=dt.getDate();
                
                var moues=dt.getHours();
                
                var minutes=dt.getMinutes();
                
                var seconds=dt.getSeconds();
                if(seconds<=9){
                    seconds="0"+seconds;
                }
//获取星期0~6之间的数 0表示星期天
                var week=dt.getDay();
                var str=doWeek(week);
                var strTime=year+"年"+moth+"月"+day+"日"+moues+":"+minutes+":"+seconds+"  "+str;

星期的具体获取 :

function doWeek(week){
                var s="";
                switch(week){
                    case 0:
                        s="星期日";
                        break;
                    case 1:
                        s="星期一";
                        break;
                    case 2:
                        s="星期二";
                        break;
                    case 3:
                        s="星期三";
                        break;
                    case 4:
                        s="星期四";
                        break;
                    case 5:
                        s="星期五";
                        break;
                    case 6:
                        s="星期六";
                        break;
        
                }
                return s;    
            }
