PPJOKE是一套基于AJAX技术网页嵌入聊天程序，目前提供asp版下载，.Net版本的负载量更高，不过还在调试中，拖了很长时间了，最近一直忙着学习，没有更新，这里先提供下载。
此外最近一直在研究持续连接技术，也就是所谓的推技术，还有jssocket等企业级的类AJAX技术，希望有经验的朋友交流。
屁屁聊天PPJoke
功能/特点
基于Ajax技术
运用了成熟稳定的prototype/scriptaculous框架
数据传送量小
页面嵌入聊天
自定义强突出个性化
支持换肤
支持表情
支持拖动放大
更改颜色
PPJOKE是根据我以前写的OTALK重写的。演示地址，向右转-->已经嵌入到了我BLOG中。
http://www.ppjoke.com
PPJOKE整站提供下载。
修改界面颜色
见rar中'ppjoke/ppjoke.css'只要相应修改成网站配色就OK
网页集成说明
将rar中的ppjoke复制到要嵌入页面的目录中，将index.htm中的一下代码复制到网页中向嵌入的div中即可
复制代码 代码如下:
<scripttype="text/javascript">
document.write("<divid='load'>正在加载....</div>");
varstyle=document.createElement("link");
style.rel="stylesheet";
style.type="text/css";
style.href='ppjoke/ppjoke.css';
style.title='ppjoke';
varhead=document.getElementsByTagName("head")[0];
head.appendChild(style);
