后台返回数据为map集合，前端js处理方法

Map<String, String> result = new HashMap<String, String>();
map.put("code", "200");
map.put("title", result.get("title"));
map.put("content", result.get("content"));
return map;

             if(data["code"]=="200"){
                var title =data["title"];
                var content = data["content"];
                alert(title);
                alert(content);
            }
