第一步:把如下代码加入<meta http-equiv="Content-Language" content="zh-cn">
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<head>区域中
<script language="JavaScript1.2">

</script>
第二步:把如下代码加入<body>区域中
<div id='KB1Parent' class='parent'><a href="default.htm" onClick="expandIt('KB1'); return false">

<SCRIPT>numTotal=14;scores[1]='KB1';scores[2]='KB1';scores[3]='KB2';scores[4]='KB3';scores[5]='KB4';scores[6]='KB5';scores[7]='KB6';scores[8]='KB7';scores[9]='KB8';scores[10]='KB9';scores[11]='KB10';scores[12]='KB11';scores[13]='KB12';scores[14]='KB13';</SCRIPT>
不知道是不是这样？
