我是靠谱客的博主整齐信封，最近开发中收集的这篇文章主要介绍asp中文数字验证码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

复制代码代码如下:

<form method="post" name=myform> 
姓　名：<input type="text" name="name" value=""><br> 
学　号：<input type="text" name="num" value=""><br> 
。。。：<input type="text" name="aaa" value=""><br> 
。。。：<input type="text" name="bbb" value=""><br> 
验证码：<img src="vcode/c.asp" onclick="this.src=this.src" title="点击图片可以更改验证码" height="13" width="52"> 
<input type="text" size="5" name="C" autocomplete="off" style="ime-mode:disabled;" value=""> 
<input type="submit" value="提交"> 
</form> 

asp代码：

复制代码代码如下:

<% 
c = Request.form("c") 
'如果可以输入小写的数字，请把下面三行注释掉 
for ii = 0 to 9 
c = Replace(c,Cstr(ii),"") 
next 
c = Replace(c,"零","0") 
c = Replace(c,"一","1") 
c = Replace(c,"二","2") 
c = Replace(c,"三","3") 
c = Replace(c,"四","4") 
c = Replace(c,"五","5") 
c = Replace(c,"六","6") 
c = Replace(c,"七","7") 
c = Replace(c,"八","8") 
c = Replace(c,"九","9") 
if Cstr(c) <> Cstr(Session("validateCode")) then 
Response.write ("验证码不正确") 
Response.end 
end if 
%>
