1、表单项目1 gbk编码格式

用户采集单是gbk编码，通过get/post提交上来的数据也是gbk格式，无需做任何处理

测试源码

<!doctype html>
<html lang="zh-cn">
<head>
<meta charset="gb2312">
</head>
<body>
<li><a href="gbkform.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >gbk同编码表单不乱码</a>
<li><a href="utf8form.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >utf8表单修改前乱码</a>
<li><a href="utf8formrepair.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >utf8表单修改为ajax方案后不乱码</a>
<li><a href="otherform.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >其他gbk同编码表单不乱码</a>
<li><a href="http://www.miaoqiyuan.cn/p/utf8-submit-gbk-ajax-autocharset" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >测试程序说明</a></a>
<hr />
<h2>get:</h2>
<form action="gbksubmit.asp" method="get" >
qq:<input name="qq" value="qq" /><br />
姓名：<input name="name" value="姓名"/><br />
地址：<input name="address" value="地址地址地址"/><br />
<button type="submit">gbk表单提交到gbk脚本后不会乱码</button>
</form>
<h2>post:</h2>
<form action="gbksubmit.asp" method="post" >
qq:<input name="qq" value="qq" /><br />
姓名：<input name="name" value="姓名"/><br />
地址：<input name="address" value="地址地址地址"/><br />
<button type="submit">gbk表单提交到gbk脚本后不会乱码</button>
</form>
</body>
</html>

2、表单项目2 utf8编码格式（可以在不同的域名下）

用户采集单是utf8编码，通过get/post提交上来的数据也是utf8格式，用表单项目1中的程序接收到的是乱码

测试代码(修改前，提交乱码)：

<!doctype html>
<html lang="zh-cn">
<head>
<meta charset="utf8">
</head>
<body>
<li><a href="gbkform.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >gbk同编码表单不乱码</a>
<li><a href="utf8form.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >utf8表单修改前乱码</a>
<li><a href="utf8formrepair.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >utf8表单修改为ajax方案后不乱码</a>
<li><a href="otherform.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >其他gbk同编码表单不乱码</a>
<li><a href="http://www.miaoqiyuan.cn/p/utf8-submit-gbk-ajax-autocharset" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >测试程序说明</a></a>
<hr />
<h2>get:</h2>
<form action="gbksubmit.asp" method="get" >
qq:<input name="qq" value="qq" /><br />
姓名：<input name="name" value="姓名"/><br />
地址：<input name="address" value="地址地址地址"/><br />
<button type="submit">utf8表单提交到gbk脚本后会乱码</button>
</form>
<h2>post:</h2>
<form action="gbksubmit.asp" method="post" >
qq:<input name="qq" value="qq" /><br />
姓名：<input name="name" value="姓名"/><br />
地址：<input name="address" value="地址地址地址"/><br />
<button type="submit">utf8表单提交到gbk脚本后会乱码</button>
</form>
</body>
</html>

不需要改变页面编码，只需要修改表单action地址，增加name=”convertcallback” value=”projecta/formgbk”、name=”convertitems” value=”name,qq,bb” 的两个 input即可，不用对页面进行其他调整
编码设置，转换器自动操作。

<form action="convert/utf8.asp"...
<input name="convertcallback" value="projecta/formgbk">
<input name="convertitems" value="name,qq,address"/>
<!-- 根据表单实际情况，修改表单项目 -->

测试代码(修改后)

<!doctype html>
<html lang="zh-cn">
<head>
<meta charset="utf8">
</head>
<body>
<li><a href="gbkform.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >gbk同编码表单不乱码</a>
<li><a href="utf8form.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >utf8表单修改前乱码</a>
<li><a href="utf8formrepair.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >utf8表单修改为ajax方案后不乱码</a>
<li><a href="otherform.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >其他gbk同编码表单不乱码</a>
<li><a href="http://www.miaoqiyuan.cn/p/utf8-submit-gbk-ajax-autocharset" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >测试程序说明</a></a>
<hr />
<h2>get:</h2>
<form action="convert/utf8.asp" method="get" >
qq:<input name="qq" value="qq" /><br />
姓名：<input name="name" value="姓名"/><br />
地址：<input name="address" value="地址地址地址"/><br />
<input name="convertcallback" value="../gbksubmit.asp" />
<input name="convertitems" value="name,qq,address" />
<button type="submit">ajax转码方案</button>
</form>
<h2>post:</h2>
<form action="convert/utf8.asp" method="post" >
qq:<input name="qq" value="qq" /><br />
姓名：<input name="name" value="姓名"/><br />
地址：<input name="address" value="地址地址地址"/><br />
<input name="convertcallback" value="../gbksubmit.asp" />
<input name="convertitems" value="name,qq,address" />
<button type="submit">ajax转码方案</button>
</form>
</body>
</html>

3、表单项目3 gbk编码格式（可以在不同的域名下）

没有任何影响，只要按照表单1的标准编写参数即可
测试代码：

<!doctype html>
<html lang="zh-cn">
<head>
<meta charset="gb2312">
</head>
<body>
<li><a href="gbkform.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >gbk同编码表单不乱码</a>
<li><a href="utf8form.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >utf8表单修改前乱码</a>
<li><a href="utf8formrepair.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >utf8表单修改为ajax方案后不乱码</a>
<li><a href="otherform.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >其他gbk同编码表单不乱码</a>
<li><a href="http://www.miaoqiyuan.cn/p/utf8-submit-gbk-ajax-autocharset" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >测试程序说明</a></a>
<hr />
<h2>get:</h2>
<form action="gbksubmit.asp" method="get" >
qq:<input name="qq" value="qq" /><br />
姓名：<input name="name" value="姓名"/><br />
地址：<input name="address" value="地址地址地址"/><br />
other1：<input name="other1" value="other1"/><br />
other2：<input name="other2" value="other2"/><br />
other3：<input name="other3" value="other3"/><br />
other4：<input name="other4" value="other4"/><br />
other5：<input name="other5" value="other5"/><br />
other6：<input name="other6" value="other6"/><br />
other7：<input name="other7" value="other7"/><br />
other8：<input name="other8" value="other8"/><br />
other9：<input name="other9" value="other9"/><br />
<button type="submit">gbk表单提交到gbk脚本后不会乱码</button>
</form>
<h2>post:</h2>
<form action="gbksubmit.asp" method="post" >
qq:<input name="qq" value="qq" /><br />
姓名：<input name="name" value="姓名"/><br />
地址：<input name="address" value="地址地址地址"/><br />
other1：<input name="other1" value="other1"/><br />
other2：<input name="other2" value="other2"/><br />
other3：<input name="other3" value="other3"/><br />
other4：<input name="other4" value="other4"/><br />
other5：<input name="other5" value="other5"/><br />
other6：<input name="other6" value="other6"/><br />
other7：<input name="other7" value="other7"/><br />
other8：<input name="other8" value="other8"/><br />
other9：<input name="other9" value="other9"/><br />
<button type="submit">gbk表单提交到gbk脚本后不会乱码</button>
</form>
</body>
</html>
