标题：武大学生成绩统计代码(FF测试通过) 出处：Felix021 时间：Tue, 20 Oct 2009 01:00:51 +0000 作者：felix021 地址：https://www.felix021.com/blog/read.php?1744 内容： 写了一段代码实现在页面上直接统计成绩的功能。 打开Firefox（注意，不支持IE6，原因是IE6的浏览器URL只支持到435个字符的js代码，IE8支持到2083，但是懒得测试了） 登录 http://202.114.74.198 OR http://202.114.74.199 点击：成绩与重修查询 -> 多科查询 或者直接打开 http://202.114.74.199/stu/query_score.jsp 然后将下列代码全部copy到页面的地址栏，回车，看到结果。 p.s. 默认情况下是先讲成绩分别以“先课程类型升序 再成绩降序”排序。可自行修改。 压缩版： javascript:var trs=new Array();trs=getData();sorttrs(10,1);sorttrs(9,0);display(trs);function sorttrs(col,di){var i,j,t;for(i=0;i trs[j+1][col]){t=trs[j];trs[j]=trs[j+1];trs[j+1]=t;}}else{if(trs[j][col]");document.writeln("公共选修: "+gx+"/"+gxx+"="+(gx/gxx)+"
