1、UTF8转GBKutf-8转化成GBK 乱码 AjaxJSPjsonGoogle 问题描述：我的jsp编码是GBK 后台的web.xlm默认也是GBK，但我想用Ajax的异步提交带中文的数据，这样到后台解析是乱码，存入数据库也是乱码。在网上找了好多方法看到问的很多解决的却很少。 网上大多解决都是用java API自带的String的一个方法，先将字符串转化成字节，然后再转utf-8。告诉大家你看到这个帖子的时候就不用再尝试这种解决办法了，那是个美丽扯。utf-8是一个汉字三个字节，当你是奇数个汉字或汉字与字母数字混合是还是有乱码。 下面是我的解决办法。 1、在jsp中我的数据输入是用texta

2、rea装载，用js给这个标签写了一个失去焦点事件 html： js： /textarea 失去焦点事件 $(#memotemp).blur(function var memotemp= $(#memotemp).val; $(#memoval).val(escape(memotemp); ); ps： 1.var memotemp= $(#memotemp).val;意思是得到textarea 里的内容。 2.escape(memotemp)意思是memotemp被escape转码。 3.$(#memoval).val(escape(memotemp);意思是将转码后的内容放入id为 memo

3、val的input里。 实际上这个id为memoval的input内容是 我们要提交给后台的。这个到后台也是一堆类似url里的那些乱码。这时候你可以用一个自己写的java方法将escape转码过的再转回原先的真实的值。这样一来你就避免了Ajax提交过程中默认编码是utf-8而你的程序中都是GBK引起的乱码问题。 下面是java代码，非小弟本人所创在网上找的。 package com.cfcc.cams.aduitmanage.util; import java.io.UnsupportedEncodingException; import java.text.SimpleDateFormat;
