后台判断用户类别
例如
<SCript LANGUAGE=JSCRIPT><%
if(user.role == "Admin")
%>
OutBarFolder1=new Array("信息模块","images/admin.gif","课程基本信息","courseInfo.do","parent.parent.main", "images/admin.gif","课程负责人信息","teahcerInfo.do","parent.parent.main","images/admin.gif","主讲教师信息","teahcerInfo.do?command=showMainTeacher","parent.parent.main");  
<%
else if(user.role == "User")
%>
.....
