我有一个这样的Json
{"0":{"parent_id":1649,"id":"1803","last_update_on":"2010-12-24 07:01:49","message":"dhb;lxd","created_by_id":"21","created_by_name":"Amol Deshpande"}}.理想情况下,我应该将长度设为1,因为我在第0个位置只有1个值.
如果我有这样的JSON怎么办？
{"0":{"parent_id":1649,"id":"1803","last_update_on":"2010-12-24 07:01:49","message":"dhb;lxd","created_by_id":"21","created_by_name":"Amol Deshpande"},"1":{"parent_id":1649,"id":"1804","last_update_on":"2010-12-24 07:02:49","message":"amol","created_by_id":"21","created_by_name":"Amol Deshpande"}}
如果我做警报,我得到的值是undefined(response.length); 响应是我上面提到的JSON
有什么建议？
