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”

转为json对象就可以操作了，建议你最好将最后那个“,”去掉，搞标准点

     var s = '[["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"],]';
    var o = eval('(' + s + ')');
    for (var i = 0; i < o.length; i++)
        alert(o[i][0] + '\n' + o[i][1]);

json 截取，

var s='[["2015-06-05 16:21:40","666"], ["2015-06-05 15:30:38","666"], ["2015-06-05 15:07:26","666"]......]';

var arr=eval('('+s+')');

for(var i=0;i<arr.length;i++){
alert(arr[i][1]);
}
