asp+ajax做聊天室二

下面的代码是post.asp文件代码.比较简单所以就不说明了.

%@Language="JavaScript" CodePage="936"%> var Nothing;
Response.addHeader("Cache-Control","no-cahce");
if(!Session.Contents("Chat_User"))
{
    Session.Contents("Chat_User") = "Guest";
    Session.Contents("Chat_Time") = (new Date).getTime();
}
if(Application.Contents("Chat_Data") == Nothing)
{
    Application.Lock();
    Application.Contents("Chat_Data") = "f系统bredb您bblueb欢迎您来到聊天室。bblackb" + (3000 + (new Date).getTime());
    Application.UnLock();
}
var PostChat = Request.QueryString.Item;
if(PostChat)
{
    var Chat_Data = Application.Contents("Chat_Data").split("f");
    if(Chat_Data.length > 30) Chat_Data.shift();
    Chat_Data.push(Server.HtmlEncode(unescape(PostChat)) + "b" + (new Date).getTime());
    Application.Lock();
    Application.Contents("Chat_Data") = Chat_Data.join("f");
    Application.UnLock();
}
var LastTime = Session.Contents("Chat_Time");
var MyData = new Array;
var AllData = Application.Contents("Chat_Data").split("f");
for(var C=AllData.length-1; C>=1; C--)
{
    var Node = new Array;
    var Item = AllData[C].split("b");
    if(Item[6]     if(Item[6] > LastTime) LastTime = Item[6];
    Node.push("" + Item[0] + "发送人>");
    Node.push("" + Item[2] + "接收人>");
    Node.push("" + Item[4] + "说话>");
    Node = Node.join("ttrn");
    Node = "t" + Node + "rnt聊天>";
    MyData.push(Node);
}
Session.Contents("Chat_Time") = LastTime;
MyData.reverse();
%>
