从服务器获得这种数据之后，如何分别取出来进行处理？

[["2015-06-05 16:21:40","666"], ["2015-06-05 15:30:38","666"], ["2015-06-05 15:07:26","666"], ["2015-06-05 14:38:21","666"], ["2015-06-05 14:38:21","666"], ["2015-06-05 14:33:18","666"], ["2015-06-05 14:23:18","666"], ["2015-06-05 14:18:16","666"], ["2015-06-05 14:15:09","666"], ["2015-06-05 14:12:16","666"], ["2015-06-05 14:12:16","666"], ["2015-06-05 14:05:34","666"], ["2015-06-05 14:01:27","666"], ["2015-06-05 13:57:44","666"], ["2015-06-05 13:57:44","666"], ["2015-06-05 13:51:23","666"], ["2015-06-05 13:51:23","666"], ["2015-06-05 13:41:43","666"],]

（1）如何将这些数据取出来放到一个数组里？
（2）如何将单个的数据：["2015-06-05 13:41:43","666"]以“,”分隔取出来，例如：我要取出后面这个数据“666”
