使用getJSON()异步请求服务器返回json格式数据

function test(){
        $.getJSON("JsonServlet",function(result){
            alert(result.name);
        });
    }

@Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        String person="{\"name\":\"zhangsan\",\"sex\":\"man\",\"age\":\"23\"}";
        resp.getWriter().print(person);
    }
