ajax 利用Servlet向html传值中文问题

稽姬 2006-08-13 10:16:38

用servlet PrintWriter 一个xml 里面有中文 ajax 的xmlhttprequest.responseXML 读取xml文件信息是js显示的中文为乱码，请问有没有什么办法可以解决。直接点就是java类给js传值，中文乱码问题。多谢各位。虽然可以把它们都转成%12%AB可以解决，但是有些麻烦，衷心求教，多谢……

我把rs2.jsp换成servlet为什么取不到返回值哦。。
大家帮忙。。。

public class jugpersonSelectedAction extends Action
{
public ActionForward execute(ActionMapping actionMapping,
ActionForm actionForm, HttpServletRequest request,
HttpServletResponse response) throws Exception
{
String forward = "success";
response.setHeader("pragma","no-cache");
response.setHeader("cache-control","no-cache");
response.setHeader("expires","0");
response.setHeader("content-type","text/xml;charset=gb2312");
System.out.println("<?xml version=\"1.0\" encoding=\"GB2312\"?>");
System.out.println("<docroot><node1>中国</node1></docroot>");

return actionMapping.findForward(forward);

}

第二个文件改一下，IE和FF都可以了

<%@ page language="java" pageEncoding="gb2312"%><%
response.setHeader("pragma","no-cache");
response.setHeader("cache-control","no-cache");
response.setHeader("expires","0");
response.setHeader("content-type","text/xml;charset=gb2312");
out.println("<?xml version=\"1.0\" encoding=\"GB2312\"?>");
out.println("<docroot><node1>中国</node1></docroot>");
%>
