如何在javascript上获取对象的所有值

我有这样的目标：

[
  {
    "pk": 2,
    "model": "gps.positions",
    "fields": {
      "power": null,
       "altitude": null,
      "time": "2014-04-08T04:00:00Z",
      "longitude": 47.916142,
      "course": null,
      "other": "",
      "device": 11,
      "address": "test",
      "latitude": 29.30661,
      "speed": null,
      "valid": null
    }
  },
  {
    "pk": 3,
    "model": "gps.positions",
    "fields":{
      "power": null,
      "altitude": null,
      "time": "2014-04-08T20:00:00Z",
      "longitude": 47.91,
      "course": null,
      "other": "",
      "device": 11,
      "address": "test2",
      "latitude": 29.30661,
      "speed": null,
      "valid": null
    }
  }
]

pk  fields.power   etc.
2    null
3    null

for(var i=0; i<data.length, i++){
    data[i].pk   //returns only one value i.e 3
}

我希望得到如下值：

[
  {
    "pk": 2,
    "model": "gps.positions",
    "fields": {
      "power": null,
       "altitude": null,
      "time": "2014-04-08T04:00:00Z",
      "longitude": 47.916142,
      "course": null,
      "other": "",
      "device": 11,
      "address": "test",
      "latitude": 29.30661,
      "speed": null,
      "valid": null
    }
  },
  {
    "pk": 3,
    "model": "gps.positions",
    "fields":{
      "power": null,
      "altitude": null,
      "time": "2014-04-08T20:00:00Z",
      "longitude": 47.91,
      "course": null,
      "other": "",
      "device": 11,
      "address": "test2",
      "latitude": 29.30661,
      "speed": null,
      "valid": null
    }
  }
]

pk  fields.power   etc.
2    null
3    null

for(var i=0; i<data.length, i++){
    data[i].pk   //returns only one value i.e 3
}

pk字段、电源等。
2空
3空
对于（变量i=0；i
var o=
变量i，l；
对于（i=0，l=o.length；i
您到底想要什么？您已经在
数据[i]中获得了价值
这是一个对象。正如你所看到的
pk
有两个值
2和3
，我只得到
3
来解释你想要实现的目标，这并不清楚当你的
I==1
时，首先循环，然后你得到
2
作为一个值。我看到你的代码在工作，我得到了这两个值“2”和“3”
