java后台用的输出流。怎么在前台用js怎么接收

后台Java代码：

     @RequestMapping(value = "/friendLinks/friendLinksList.do")
    public void getfriendLinksList(HttpServletRequest request,
            HttpServletResponse response, ModelMap modelMap){

        response.setCharacterEncoding("UTF-8");
        String pageNoStr = request.getParameter("pageNo");
        Integer pageNo = 0;

        try {
            pageNo = Integer.valueOf(pageNoStr);
        } catch (Exception e) {
            pageNo = 0;
        }
        Page page = new Page();
        page.setPageNo(pageNo);

        //按分页条件查询用户
        List linksList = null;
        try {
            linksList = friendLinksService.getFriendLinksList(page);
            //将查出来的友情链接和分页信息放到json字符串中
            JSONArray jsonList = new JSONArray();
            JSONObject bj = JSONObject.fromObject(page);
            jsonList.add(bj);
            for (FriendLinks links : linksList) {
                JSONObject obj = JSONObject.fromObject(links);
                jsonList.add(obj);
            }
            response.getWriter().println(jsonList.toString());
            response.getWriter().flush();
            response.getWriter().close();
        } catch (Exception e) {

            e.printStackTrace();
        }
        return ;
    }

JS中代码：

     function fillData(pageNo) {
    if (pageNo == "") {
        pageNo = thisPageNo;
    }

    var stateValue = $("#stateValue").val();
    var titleValue = $("#titleValue").val();

    $.ajax({
            url:contextPath + "/friendLinks/friendLinksList.do", 
            type:"POST",
            data:{
                  pageNo:pageNo,
                  stateValue:stateValue,
                  titleValue:titleValue
                 }, 
            dataType:"json", 
            beforeSend:function () {
            $("#pageTd a").remove();
    }, success:function (data) {
            var page = data[0];
            if (page.count == 0) {
                var noDataMsg = "无相关数据";
                $("#dataBody").html(noDataMsg);
                var pageMsg = "总记录数：0"+
                              "  当前页：0/0  "+
                              "首页 "+
                              "上一页 "+
                              "下一页 "+
                              "尾页 ";
                              $("#pageButtonBefore").html(pageMsg);
            } else {
                var dataMsg = "";
                var caozuo = "";
                var useOrNot = "";
                for (var i = 1; i < data.length; i++) {
                    caozuo = "";
                    caozuo = caozuo + "查看";
                    caozuo = caozuo + "修改";
                    caozuo = caozuo + "删除";


                    if(data[i].status == "0"){

                        status = "是";
                    }else{
                        status = "否";
                    }
                    dataMsg = dataMsg + "" + i + 
                                        "" + data[i].linkName + 
                                        "" + data[i].linkSite + 
                                        "" + status + ""; 
                    dataMsg = dataMsg + caozuo;                 
                    dataMsg = dataMsg + "";
                }
                $("#dataBody").html(dataMsg);

                var pageMsg = "总记录数："+page.count+"  当前页："+page.pageNo+"/"+page.totalPage+"  "+
                              "首页  "+
                              "上一页  "+
                              "下一页  "+
                              "尾页  ";
                $("#pageButtonBefore").html(pageMsg);
            }
    }, error:function () {
          alert("获取相关数据失败！");
    }});

} 其实能看出来，JS怎么接收值跟后台用什么方式传没有多大关系，关键是看传过来的值格式是啥就好了。
传回来的是字符串，那就直接按照字符串处理，传回来的是Json格式的那就直接按照解析Json来处理。
