用asp读数据库，然后初始化js的数组，因为js只会改，不会写，那位大哥指点一下。谢了，顺便学习一下js的数组

给你js数组写法
var x_array = new Array(数组长度);
或：var x_array = new Array(初始化列表);

房间信息存放到room数组里
用户信息存放在user数组里
聊天内容存放在log对象里，是Scripting.Dictionary对象，

整个程序是无刷新聊天室，还没有做完呢，看见有人能用上就放上来了，希望楼主能用的上。呵呵
chat_user.asp代码：

<%
Response.Expires = -1
Response.ExpiresAbsolute = Now() - 1
Response.cachecontrol = "no-cache"
set rs=conn.execute("select * from chat_user where state=1 order by userid")
while not rs.eof
response.Write(escape( rs("userid")&"*"&rs("nickname")&"#" ))
rs.movenext
wend
%>
chat_room.asp代码：

<%
Response.Expires = -1
Response.ExpiresAbsolute = Now() - 1
Response.cachecontrol = "no-cache"
set rs=conn.execute("select * from chat_room order by id desc")
while not rs.eof
response.Write(escape( rs("id")&"*"&rs("roomname")&"#" ))
rs.movenext
wend
%>
chat_log.asp代码：

<%
Response.Expires = -1
Response.ExpiresAbsolute = Now() - 1
Response.cachecontrol = "no-cache"
set rs=conn.execute("select top 10 * from chat_log where chat_id>"&request("id")&" order by chat_id desc")
while not rs.eof
response.Write(escape(rs("chat_id")&"*"&rs("roomid")&"*"&rs("sendtime")&rs("msgBody")&"#" ))
rs.movenext
wend
%>
