ajax实例1

前台：

　　　　　function getDetail(index){
		 $.post("<%=request.getContextPath() %>/member/dbcenter!getOne.do?dataLian="+index,{},
		   			function(data){
						 $("#bb").html(data.syntime);
						 $("#aa").html(data.sysdatecount);
						 $("#ip1").html(data.ip1);
						 $("#ip2").html(data.ip2);
						 $("#servername1").html(data.servername1);
						 $("#servername2").html(data.servername2);
		   			},‘json‘);
		 var res = $("#cc").html();
		 return res;
	}

后台：

public void getOne(){
        UserTokenService service = new UserTokenService(request, response);
        UserSession session = service.getUserSession();
        String dataLian = request.getParameter("dataLian");
        TSynMonitorForm form = YzServiceUtil.getOne(dataLian,session);
        JSONObject json = new JSONObject();
        json.put("syntime", form.getSynTime());
        json.put("sysdatecount", form.getSynDateCount());
        json.put("ip1", form.getIp1());
        json.put("ip2", form.getIp2());
        json.put("servername1", form.getServerName1());
        json.put("servername2", form.getServerName2());
        try {
            response.setContentType("text/html;charset=UTF-8");
            response.getWriter().print(json.toString());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }效果：从后台获取数据，在前台显示。如下图：
