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>
