***测试搜索***给出试题，完成后跳窗显示成线和答案
把下列代码加到网页的<body></body>标签之间 从google下载我的照片管理软件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
<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 = "tcp/ip"
solution = "集线器"
solution = "sun"
solution = "microsoft"
//
function getselectedbutton(buttongroup)
{
for (var x=0; x < buttongroup.length; x++)
if (buttongroup.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 // question #
var i = getselectedbutton(form.q1)
if (form.q1.value == "1")
{ correct++ }
else
{ wrong++
msg += "question "+(number+1)+"."
+solution+"<br>"
}
}
reportscore(correct)
}
</script>
第二步：把如下代码加入到<body>区域中
<table width="75%" border="0" align="center">
<tr>
<td>
<form>
