要完成此效果需要两个步骤 第一步：把如下代码加入到区域中 <script language="JavaScript"> var Total_Question = 4 // 修改这里与题目数量一致 var msg = "" // 正确答案 var Solution = new Array(Total_Question) Solution[0] = "TCP/IP" Solution[1] = "集线器" Solution[2] = "SUN" Solution[3] = "Microsoft" // function GetSelectedButton(ButtonGroup) { for (var x=0; x < ButtonGroup.length; x++) if (ButtonGroup[x].checked) return x return 0 } function ReportScore(correct) { var SecWin = window.open("","scorewin","scrollbars,width=300,height=220") var MustHave1 = "" var Percent = "

测验成绩 : "+Math.round(correct/Total_Question*100) + "

---

" lastscore=Math.round(correct/Total_Question*100) if (lastscore == "100"){ msg = MustHave1 +Percent + "恭喜，全部答对了！

" + msg + ""} else { msg = MustHave1 +Percent + "正确答案：

" + msg + "" } SecWin.document.write(msg) msg = "" //清空msg } function Grade() { var correct = 0 var wrong = 0 for (number=0; number < Total_Question; number++) { var form = document.forms[number] // Question # var i = GetSelectedButton(form.q1) if (form.q1[i].value == "1") { correct++ } else { wrong++ msg += "Question "+(number+1)+"." +Solution[number]+"
" } } ReportScore(correct) } </script> 第二步：把如下代码加入到区域中
