            var day = now.getDay();
            var oneDayLong = 24 * 60 * 60 * 1000;
            //计算这一周

            for (var i = 1; i < 8; i++) {
                var SundayTime = nowTime + (i - day) * oneDayLong;
                var SundayTime = new Date(SundayTime);
                var y = SundayTime.getFullYear();//年
                var m = SundayTime.getMonth() + 1;//月
                var d = SundayTime.getDate();//日
                var h = SundayTime.getHours();//时

                var s = SundayTime.getSeconds();//秒
                var val = y+"/"+m+"/"+d;
               alert(val);
