要完成此效果需要两个步骤

第一步：把如下代码加入到<head>区域中

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>

第二步：把如下代码加入到<body>区域中
