我不清楚把我的毕业设计的东西放上来之后，毕业论文答辩的时候会不会说我是在网上抄袭的，不过我还是果断的发上来与大家分享了！！呵呵，请大家支持！高手就绕道吧！

　　现在已经放到公网上，并且开始使用，兼容IE6以上各IE浏览器，Chrome，Firefox等。欢迎大家注册账号测试，注意如有使用特殊字符进行测试的，请测试完以后即使删除相关内容，以免给网站带来不美观的影响。谢谢！

　　这是访问地址：http://www.yestz.com    由于iis连接数有限制，可能会出现问题，如遇到问题请关闭页面，稍后再试，谢谢。

　　其中涉及到的有：Server-Push（Comet），smtp，jQuery，jQueryUI，XHTML+CSS，Json，Jcrop，图形图像处理技术，Ajax，ADO.NET，kindeditor

开发工具包括：Visual Studio 2010、SqlServer 208、Notepad++、Editplus、SVN版本控制、Chrome、Firefox、IEtest、flashFXP、IIS6.0、IIS7.5

整个项目的流程图如下：

在这里与大家分享几个部分源代码：自己封装的类库与jQuery方法：

自定义jQuery方法：widgetUI 1.0   点击这里下载

/*
* widgetUI 1.0
* Copyright (c) 2011 陈盛泰，阿泰  http://www.cnblogs.com/chenshengtai
* Date: 2011-11-1
* 在FireFox、Chrome、IE8、IE7、IE6中通过测试
*《 使用说明》
* 1、基于jQuery的函数封装，需要在页面中引入jQuery以及jQueryUI样式。
* 2、使用widgetUI可以方便地将表格提示使用体验，给body加上蒙层，弹出当前对话框，若不定义width、height，默认值为300px；
* 3、若再iframe中使用，需要设置iframe值为其id的值，不是很灵活，需要将内部的触发函数写在该页面的父页面上。
* 4、该div中事件应该这样处理，
如：$(".testbtn").click(function () {alert("成功！");});
修改成：$(".testbtn").live("click",function () {alert("成功！");});
