Lodash基于键的对象排序列表

Question

我正在寻找基于密钥对对象列表进行排序

这是我的目标

var Categories =    {

      "social": [
        {
          "id": "social_001",
          "lastModified": "2 Day ago"
        }
      ],
"communication": [
        {
          "id": "communication_001",
          "lastModified": "4 Day ago"
        },
        {
          "id": "communication_002",
          "lastModified": "1 Day ago"
        }
      ],
      "storage": [
        {
          "id": "storage_001",
          "lastModified": "3 Day ago"
        }
      ]
    }

所以在输出排序对象将排序为开始与沟通, 社交, 存储 建议我一些帮助.

Answer 1

这是使用lodash的解决方案:

var Categories = {
  "social": [
    {
      "id": "social_001",
      "lastModified": "2 Day ago"
    }
  ],
  "communication": [
    {
      "id": "communication_001",
      "lastModified": "4 Day ago"
    },
    {
      "id": "communication_002",
      "lastModified": "1 Day ago"
    }
  ],
  "storage": [
    {
      "id": "storage_001",
      "lastModified": "3 Day ago"
    }
  ]
}

var ordered = {};   
_(Categories).keys().sort().each(function (key) {
  ordered[key] = Categories[key];
});

Categories = ordered;
