js 解决ajax post 中文乱码问题

 上面的设置都没有用

启了N次WEBSPHERE才解决了这个问题，共了几个小时的时间

在提交的页面发送请求的代码如下:

   http_request.open("POST",document.forms[formNumber].action,false);

http_request.setrequestheader("cache-control","no-cache"); 

    http_request.setrequestheader("Content-Type","application/x-www-form-urlencoded");

    http_request.setrequestheader("contentType","text/html;charset=uft-8");

    http_request.setRequestHeader("RequestType","ajax");

    data=encodeURI(data);

    data=encodeURI(data);

http_request.send(data);

在服务器端用String value=java.net.URLDecoder.decode(request.getParameter(key),"UTF-8");

即可
