PHP+Ajax异步通讯实现用户名邮箱验证是否已注册( 2种方法实现)
前 言
直接上代码有点不厚道、于是按照天朝传统，整段描述吧。。。。（本人语言表达能力有限，大家忍着看）
功 能
在网站注册用户时使用，主要为了无刷新异步验证用户输入的用户名或者Email是否已注册。
这功能大家肯定见过，大多数网站都有的，我一直对这个功能很感兴趣，所以这几天研究了下 jQuery + Ajax
整了一个功能不算完善，但足以应付普通使用的代码 (更牛的功能大家自己去发掘)
文 件 说 明
reg.php //为注册页面
check_user.php //为用户验证页面 (GET,POST方式任选)
jquery-1.7.1.js //为jQuery文件 下载地址：http://code.jquery.com/jquery-1.7.1.js (右键另存为即可)
代码示例
reg.php 注册页面（内含2种方式，请任选一种）
复制代码 代码如下:
