在线考试脚本(二)

下面框中为脚本显示区

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>
