这样写思路会不会太绕了- =

<script type="text/javascript">
//通过javascript的日期对象来得到当前的日期，并输出。
var date = new Date();
var weekday = ["星期日","星期一","星期二","星期三","星期四","星期五","星期六"];
var year = date.getFullYear();
var month = date.getMonth()+1;
var day = date.getDate();
//成绩是一长窜的字符串不好处理，找规律后分割放到数组里更好操作哦
var scoreStr = "小明:87;小花:81;小红:97;小天:76;小张:74;小小:94;小西:90;小伍:76;小迪:64;小曼:76";

}
var average = sum/count;
//从数组中将成绩撮出来，然后求和取整，并输出。
document.write(year+"年"+month+"月"+day+"日"+" "+weekday[date.getDay()]+"--班级总分为:"+average);
