js json格式字符串

是这个意思？
var data=obj.data;
for(var k in data){
console.log(k);//猎神OL_安卓
var arr=data[k];
for(var i=0;i<arr.length;i++){
var o=arr[i];
console.log(o.countOfNewUsers);//countOfNewUsers的值
}
}

{
   "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"
        }
]
}
把你的数据
var data={
   "data": {
     "猎神OL_安卓": [
...
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
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
d = {
   "data": {
     "一组": [
        {
            "gameId": 10,
            "promptChannelId": null,
            "countOfNewUsers": 100,

        {

            "countOfNewUsers": 100,

            "proportion": null,
            "showedTimePattern": "01:00~~02:00"
        }
     ]
"二组": [
        {
            "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"
        }
     ]
  }
};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？
