访问对象内的数组

Question

我有一个如下所示的对象结构。我根据id值

使用下划线js进行了这样的分组

  {
      "1": [
        {
          "id": 1,
          "tailName": "ABQ-PHX",
          "itemId": 1,
          "name": "a1",
          "start": "24-11-2013,2:38",
          "end": "29-11-2013,18:22"
        },
        {
          "id": 1,
          "tailName": "ABQ-PHX",
          "itemId": 9,
          "name": "a2",
          "start": "16-12-2013,10:46",
          "end": "18-12-2013,10:46"
        }
      ],
      "2": [
        {
          "id": 2,
          "tailName": "BNA-RDU",
          "itemId": 14,
          "name": "b1",
          "start": "21-11-2013,11:38",
          "end": "15-12-2013,7:52"
        }
      ]
    }

请告知如何从上述对象访问阵列。

我想访问第一个数组（即）

[
        {
          "id": 1,
          "tailName": "ABQ-PHX",
          "itemId": 1,
          "name": "a1",
          "start": "24-11-2013,2:38",
          "end": "29-11-2013,18:22"
        },
        {
          "id": 1,
          "tailName": "ABQ-PHX",
          "itemId": 9,
          "name": "a2",
          "start": "16-12-2013,10:46",
          "end": "18-12-2013,10:46"
        }
      ]

Answer 1

your_object[1]和your_object["1"]都会为您提供结果。
