使用AngularJS显示json数据

Question

当我的程序获得这样的JSON响应时：

[
    {
      "index": 1,
      "name": "Samantha",
      "rarity": "Scarborough",
      "email": "maureen@sykes.mk"
    },
    {
      "index": 2,
      "name": "Amanda",
      "rarity": "Vick",
      "email": "jessica@livingston.mv"
    }
]

AngularJS显示ng-repeat欺骗错误。我也尝试过使用：$index跟踪。

但如果我的JSON响应是这样的：

{"items": 
   [
    {
      "index": 1,
      "name": "Samantha",
      "rarity": "Scarborough",
      "email": "maureen@sykes.mk"
    },
    {
      "index": 2,
      "name": "Amanda",
      "rarity": "Vick",
      "email": "jessica@livingston.mv"
    }
  ]
}

我可以使用ng-repeat = "name in variable.items"

轻松显示JSON

为什么AngularJS的行为如此？
