从json字符串获取数据

我是一个非常漂亮的n00b与JavaScript和jQuery，所以我在这里尽我所能。我有一个来自Stackmob查询的JSON返回。我需要知道如何从此JSON字符串中正确获取name,distance,lat和lon，以便我可以在google api调用中进一步使用它们。从json字符串获取数据

[ 
    { 
     "name": "eBay", 
     "lat_long": { 
      "lon": -121.927551, 
      "lat": 37.29546, 
      "distance": 0.004635090828588474 
     }, 
     "locations_id": "a3563711ebb44a088ae5ab2bd7ff2e0e" 
    }, 
    { 
     "name": "Facebook", 
     "lat_long": { 
      "lon": -121.894955, 
      "lat": 37.339386, 
      "distance": 0.005523591746943001 
     }, 
     "locations_id": "3fbee8e363bf4247b2e8ca0958c38f4e" 
    }, 
    { 
     "name": "Yahoo", 
     "lat_long": { 
      "lon": -122.025159, 
      "lat": 37.417237, 
      "distance": 0.006310220058572611 
     }, 
     "locations_id": "d0c568a6322f4a3b8d2fe30cba68f8f1" 
    }, 
    { 
     "name": "Hewlett Packard", 
     "lat_long": { 
      "lon": -122.145989, 
      "lat": 37.415515, 
      "distance": 0.006312489443257717 
     }, 
     "locations_id": "f03676c3469d4b978bfefcb2ab13790d" 
    }, 
    { 
     "name": "Google", 
     "lat_long": { 
      "lon": -122.083979, 
      "lat": 37.421931, 
      "distance": 0.006351811575525541 
     }, 
     "locations_id": "56325f71322a4c70ab0e3f1b3fb7fd9b" 
    } 
]

我返回的对象是model并且Ive试图通过循环模型[I]。名称等，但在Firebug得到空字符串引用。

'JSON [N] .name和JSON [ n] .lat_long.lat'等，其中'n'是数组索引 – Phil

你可以这样做：

for(var i = 0; i < model.length; i++) { 
    console.log(model[i].name); //shows eBay, Facebook, etc 
    console.log(model[i].lat_long.lat); //gives value of lat 
    console.log(model[i].lat_long.distance); //gives distance value for each 
}
