1.解决POST传送�ؕ码的问题�Q?br />
    Set Character Encoding
    com.util.filters.SetCharacterEncodingFilter

      encoding
      UTF-8


    Set Character Encoding
    /*

SetCharacterEncodingFilter:

package com.util.filters;

import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.UnavailableException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class SetCharacterEncodingFilter
implements Filter {

protected String encoding = null;

protected FilterConfig filterConfig = null;

protected boolean ignore = true;

public void destroy() {

this.encoding = null;
this.filterConfig = null;

}

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {

    // Conditionally select and set the character encoding to be used
   request.setCharacterEncoding("GBK");
    // Pass control on to the next filter
    chain.doFilter(request, response);

}

public void init(FilterConfig filterConfig) throws ServletException {

    this.filterConfig = filterConfig;
    this.encoding = filterConfig.getInitParameter("encoding");
    String value = filterConfig.getInitParameter("ignore");
    if (value == null) {
      this.ignore = true;
    }
    else if (value.equalsIgnoreCase("true")) {
      this.ignore = true;
    }
    else if (value.equalsIgnoreCase("yes")) {
      this.ignore = true;
    }
    else {
      this.ignore = false;
    }

}

protected String selectEncoding(ServletRequest request) {

return (this.encoding);

}

2�Q�解决GET方式出现��q��的方�?/p>

tomcat的server.xml�?

注意其中的useBodyEncodingForURI="true"�q�句是是解决问题的关键，但缺省情况下没有�Q�自己加�q�去�?
然后再用Filter�Ҏ��解决解决GET的问�?/p>

3.��q��字符转换　
　　byte[] bytes = str.getBytes("ISO8859-1");
String dept=new String(bytes);

AJAX
在用XMLHttpRequest发送请求时如用post方式传送数�?�Ҏ��出现中文��q��问题!
在Ajax�?默认的编码方式是UTF-8,所以在服务器端用request.setCharacterEncoding("UTF-8");(对于java�a�,其它语言可能�c�M��Ҏ��)讄��~�码卛_��解决大部份的�~�码问题!

对于服务器端�q�回的XML文�g在用responseXML��d��时也要注意编码问�?

以下是正��的处理�Ҏ��Q?/p>

response.setCharacterEncoding("UTF-8");-----(1)
PrintWriter out=response.getWriter();------(2)
out.println("�q�回内容");

如上所�C?如果1�?的先后顺序发生变化就会��生�ؕ码！

javascript判断数字
function isdigit(s)
{
var r,re;
re = /\d*/i; //\d表示数字,*表示匚w��多个数字
r = s.match(re);
return (r==s)?1:0;
}

request.getParameter("ss") 若ss不存在，��gؓnull
若ss的value为空�Q�返回��gؓ""
