当我门用下边的对象及方法(ajax)
??????????xh???=???new???ActiveXObject("Microsoft.XMLHTTP")?????
??????????xh.onreadystatechange???=???getReady?????
??????????xh.open("POST","/test/zhongwen.jsp",false)??
向服务器端传送中文数据时,zhongwen.jsp得到parameter的值就会是乱码。
那么我们怎么解决这个问题呢？

首先在页面用js的escape方法去转码
其次server端获取转码后的数据后，就用下边这个类Escape的unescape方法解码
