脚本说明:
第一步:把如下代码加入<head>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 = "<HTML><HEAD><TITLE>测验成绩报告</TITLE></HEAD><BODY>"
var Percent = "<H2>测验成绩 : "+Math.round(correct/Total_Question*100)
+ "</H2><HR>"
lastscore=Math.round(correct/Total_Question*100)
if (lastscore == "100"){
msg = MustHave1 +Percent + "<font color='red'>恭喜，全部答对了！</font><p>" + msg + "<input
type='button' value='close' onclick=javascript:window.close()></BODY></HTML>"}
else {
msg = MustHave1 +Percent + "<font color='red'>正确答案：</font><p>" + msg + "<input type='button'
value='close' onclick=javascript:window.close()></BODY></HTML>"
}
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]+"<BR>"
}
  }
  ReportScore(correct)

}

</script>
