用AJAX来GET回一个页面时，RESPONSETEXT里面的中文多半会出现乱码，这是因为xmlhttp在处理返回的responseText的时候，是把resposeBody按UTF-8编码进解码考形成的，如果服务器送出的确实是UTF-8的数据流的时候汉字会正确显示，而送出了GBK编码流的时候就乱了。解决的办法就是在送出的流里面加一个HEADER，指明送出的是什么编码流，这样XMLHTTP就不会乱搞了。
PHP:header('Content-Type:text/html;charset=GB2312');
ASP:Response.Charset("GB2312")
JSP:response.setHeader("Charset","GB2312");
