Establish a good experience Web registration system ajax_javascript skills

*项目名称:具有良好体验度的Web注册系统
*作者:草履虫
*联系:caolvchong@gmail.com
*时间:2007-6-29
*起因和版权说明:
  1.蓝色理想上有位会员发布了个类似的系统,提问说验证码不支持firefox的刷新,于是萌生念头做一个.本系统外观(按钮取色等)借鉴了该系统,但细节实现原理并不相同(该文地址:http://bbs.blueidea.com/thread-2761325-1-4.html).
  2.另外,自己做的这个注册系统中利用了网络上的无组件验证码(作者sipo)
  3.至于密码强度的算法借鉴了蓝色理想的一篇文章(http://www.blueidea.com/tech/web/2006/4324.asp),但该算法并不十分理想,如果有更好算法的朋友不妨交流一下
*特点和知识点:
  1.AJAX验证用户名和验证码,同时异步进行用户名注册(都属于AJAX的很基础部分)
  2.支持验证码刷新(包括firefox平台下)
  3.密码,邮箱,用户名等即时检测(利用javascript DOM)
  4.HTML通过W3C Strict验证,CSS也通过W3C CSS验证(其实这个有点多余,并不完全必要)
*开发平台:Windows2003 IIS6.0 Access数据库
*工具:DreamWeaver(写ASP),Aptana(写Javascript,HTML和CSS),Emeditor(写这篇文章),Access2003(数据库)
*测试平台:Firefox2.0,Opera9.21,IE6.0,IE7.0
*演示地址:http://finish.3322.org/reg/reg.htm(短期有效,在本机上,可能访问不顺畅)
*原文地址:http://cceer.xmu.edu.cn/blog/view.asp?id=52
*补充:
  如果你使用这个注册系统,请务必注意下列问题:
    本系统没有对密码进行加密,如果需要,可以搜索MD5加密
    本系统没有进行防注入设置,如果需要,可以搜索SQL防注入
  限于本人水平上的限制,错误和不足在所难免,如果你有问题或者建议,请联系我,感谢!
