高手帮忙啊～！～jsp页面调用javascript问题．
问题描述:根据管理员的权限在左边导航栏显示相应的功能模块,单击右键的查看源代码,可以看到一级目录和二级目录都可以得到.但是在页面一级目录却不能展开.(二级树状菜单)
代码如下：
<%@page contentType= "text/html;charset=gb2312 "
import= "com.cmesn.struts.action.left_list,java.sql.* "%>
<%@ page import= "com.cmesn.struts.Bean.MySqlAdminDAO "%>
<%@ page import= "com.cmesn.struts.form.LoginForm; "%>
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
<style type= "text/css ">
<!--
.STYLE1 {font-size: 2}
--> a{TEXT-DECORATION:none}
a:link{color:#800080}
a:visited{color:#800080}
a:hover{color:#800080}
</style>
</head>
<body>
<script language= "javascript ">
function ShowTR(objImg,objTr){
if(objTr.style.display== " "){
objTr.style.display= "none ";
objImg.src= "../img/jia.gif ";
objImg.alt= "展开 ";
}else{
objTr.style.display= "block ";
objImg.src= "../img/jian.gif ";
objImg.alt= "折叠 ";
}

String passwd = (String) sion.getAttribute( "admin_passwd ");
System.out.println( "************************** " + name);
System.out.println( "********************************* " + passwd);
MySqlAdminDAO dd = new MySqlAdminDAO();
String powers = dd.getPowers(name, passwd);
String[] s = powers.split( ", ");
for (int i = 0; i < s.length; i++) {

conn = new left_list();

rs_superType = conn.check(sqls);
System.out.println( "####################### " + sqls);
// }
int ID_superType = 0;//获取ID
String superType = " ";//获取分模块
int m = 1;
while (rs_superType.next()) {
ID_superType = rs_superType.getInt(1);//获取ID编号

ResultSet rs_subType = conn.check(sql);
String subType = " ";
int subID = 0;
//获取记录数
rs_subType.last();
int subType_RC = rs_subType.getRow();
rs_subType.first();
