  }
};

数据是这样的，按照这样的方式 a = []; for(k in d.data) a.push(k); 取出值并且放到数组中。这些数据是通过highcharts 作为图表数据以折线图展示出来。它所需要的结构是这样的：

series: [
			         {
			            name: '一组',
			            data: [100, 100]
			        }, {
			            name: '一组',
			            data: [100, 200, ]
			        }

data 是countOfNewUsers 某条数据的集合，能通过js 把json格式数据弄成这种结构的吗？

其实你只是 data 下的第一层（猎神OL_安卓）键名是不固定的所以可以先提取出来

d = {
   "data": {
     "猎神OL_安卓": [
        {
            "gameId": 10,
            "promptChannelId": null,
            "countOfNewUsers": 100,
            "startDate": null,
            "endDate": null,
            "createdDate": "2014-06-05",
            "hourSpanType": 0,
            "proportion": null,
            "showedTimePattern": "00:00~~01:00"
        },
        {
            "gameId": 10,
            "promptChannelId": null,
            "countOfNewUsers": 100,
            "startDate": null,
            "endDate": null,
            "createdDate": "2014-06-05",
            "hourSpanType": 1,
            "proportion": null,
            "showedTimePattern": "01:00~~02:00"
        }
     ]
  }
};
a = [];
for(k in d.data) a.push(k);
alert(a);

到使用的时候 p = d.data[a[0]][1].countOfNewUsers

json 格式字符串怎么取得 "猎神OL_安卓" 这个key值多个循环，key不是固定值还有countOfNewUsers 的值

这样是可以获取到值，需要得到所有的值怎么办？在for循环里控制台可以输出所有的k值，可是在for之外怎么获取让函数返回所有的值
