pushlet實現webQQ即時通信

後臺維護界面展現：

                                                                 後臺首頁

 

 

 

                                                      賬戶及其人員列表

 

人員的組織及其所在羣組的維護頁面就不在展現下面展現客戶端。

 

                     用戶登錄

 

               鼠標懸停

 

 

                  維護狀態

 

 

                   鼠標右鍵

 

 

                                               查看人員信息

 

 

 

                                            查看聊天記錄

 

 

                                          維護個人資料

 

 

 

                                           聊天窗口

 

 

 

                                         互相附件傳送

 

 

                 IM實現消息提醒

 

                                  實現羣組之間的聊天

 

以上是IM（即時通信）一些基本功能的簡介，好了就先到此爲止吧。。。。。

在Pushlet的應用方面希望可以與大家相互交流，互相學習。

 

 

 

 

JavaScript兩種發送消息的方式不用多說

1、Ajax保持心跳的即時通信

2、往前臺輸送HTML的即時通信

 

下面貼Java實現即時通信的代碼
