action传json对象，及前台接收json对象

Action:

                //转成JSON字符串

		String jsonStr = this.listToJson(list);

		//转成JSON字符串JSONArray jsonList = JSONArray.fromObject(list);String jsonStr = jsonList.toString();		

		//声明JSONObject
		JSONObject data = new JSONObject();
		//以下实现将JSON字符串传到前台
		response.setContentType("text/json");
		response.setCharacterEncoding("UTF-8");
		PrintWriter out = null;
		try {
			out = response.getWriter();
			data.put("size", list.size());
			data.put("totalRows", totalRows);
			data.put("pageCount", pageCount);
			data.put("StrListContext", jsonStr);
			out.println(data.toString());
		} catch (IOException e) {
			logger.error("FareAction:queryFareDetail" + e.getMessage());
		} catch (JSONException e) {
			logger.error("FareAction:queryFareDetail" + e.getMessage());
		} finally {
			out.flush();
			out.close();
		}

JS:

//查询回调函数	
function doQueryActioin(data)
  data.size;//size属性
