jquery ajax jsp 傳回值亂碼二向解決方案

jquery ajax 網頁特效p/jsp.html target=_blank >jsp教程 傳回值亂碼二向解決方案在以前開發ajax時經常會碰到亂碼，今天我們用jquery ajax+jsp時，又出來亂碼了，經常測試找到了二種處理jquery ajax亂碼問題，下面看看。

<script>
$().ready(function(){
var url="/www.111cn.net/ajaxgetnewsclassfather.do";
var pars="random="+math.random();
var newsclassfather= $('#newsclassfather');
        $.ajax({
            url : url,
            data : pars,
            type :"post",
            success :function(res){
                newsclassfather.append(res);
            }
        });
    });

</script>

<%
//ajaxgetnewsclassfather.do

public void ajaxgetnewsclassfather(writer writer, model model, https教程ervletrequest request, httpservletresponse response)
    {
        response.setcontenttype("text/html");
        response.setcharacterencoding("utf-8");
        string dbname= cookieutil.getdbname(request, response);
        list<newsclass> newsclasslist= newsclassjdbcservice.findbybclassid(dbname,0);
        string result="";for (newsclass newsclass : newsclasslist)
        {
            result+="<option value='"+ newsclass.getclassid()+"'>"+ newsclass.getclassname()+"</option>";
        }try
        {
            writer.write(result);
        }catch (ioexception e)
        {
            e.printstacktrace();
        }
    }
/*
傳回值全部為亂碼

解決方案一

<%@ page language="java" contenttype="text/html; charset=utf-8"%>

解決ajax亂方法二,加個過濾器
