大神帮我看看 算不出sum 谢谢
<script type="text/javascript">
//通过javascript的日期对象来得到当前的日期,并输出。
var mydate=new Date();
var myweek=["星期日","星期一","星期二","星期三","星期四","星期五","星期六"];
document.write(mydate.getFullYear()+"年"+(mydate.getMonth() + 1)+"月"+mydate.getDate()+"日"+myweek[mydate.getDay()]);
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 str=scoreStr.split(";");
//document.write(str);测试分隔
var Sore=new Aarry();
var sum=0;
for(var i=0;i<=str.length;i++){
sum += parseInt(str[i].substr(str[i].indexOf(":")+1));
}
document.write("班的总成绩是"+sum);
