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=”https://www.jb51.net/article/gbkForm.html” rel=”external nofollow” rel=”external nofollow” rel=”external nofollow” rel=”external nofollow” >GBK同编码表单不乱码</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=”https://www.jb51.net/article/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=”https://www.jb51.net/article/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=”https://www.jb51.net/article/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=”https://www.jb51.net/article/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=”https://www.jb51.net/article/gbkForm.html” rel=”external nofollow” rel=”external nofollow” rel=”external nofollow” rel=”external nofollow” >GBK同编码表单不乱码</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=”https://www.jb51.net/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=”https://www.jb51.net/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=”https://www.jb51.net/article/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=”https://www.jb51.net/article/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=”https://www.jb51.net/article/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=”https://www.jb51.net/article/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 />
