Question

我有一个对象。我想根据id对它进行排序。

这是我的数据

{
  1918: {
    id: "1544596802835",
    item_id: "1918",
    label: "Soft Touch  Salt Free Mint 500 ml (000001400045)",
    combo_items: false
  }

  6325: {
    id: "15445968134652",
    item_id: "6325",
    label: "Mirindas Orange Flover 300 ml (012000800160)",
    combo_items: false
  }

  6336: {
    id: "15445968106815",
    item_id: "6336",
    label: "Sting Energy 250ml (012000034220)",
    combo_items: false
  }

  6498: {
    id: "1544596806967",
    item_id: "6498",
    label: "Tido Candy (01)",
    combo_items: false
  }

  7461: {
    id: "15445968057103",
    item_id: "7461",
    label: "Skin Whitening Facial Kit (000051032012)",
    combo_items: false
  }
}

Answer 1

首先，您不应该依赖JavaScript对象中的属性顺序（有关详细信息，请参见this question），这意味着您需要将对象排序为数组。

使用Array.prototype.sort()可以轻松完成此操作：

const sorted = Object.values(data).sort((a, b) => a.id - b.id);

完整代码段：

const data = {
  1918: {
    id: "1544596802835",
    item_id: "1918",
    label: "Soft Touch  Salt Free Mint 500 ml (000001400045)",
    combo_items: false
  },
  6325: {
    id: "15445968134652",
    item_id: "6325",
    label: "Mirindas Orange Flover 300 ml (012000800160)",
    combo_items: false
  },
  6336: {
    id: "15445968106815",
    item_id: "6336",
    label: "Sting Energy 250ml (012000034220)",
    combo_items: false
  },
  6498: {
    id: "1544596806967",
    item_id: "6498",
    label: "Tido Candy (01)",
    combo_items: false
  },
  7461: {
    id: "15445968057103",
    item_id: "7461",
    label: "Skin Whitening Facial Kit (000051032012)",
    combo_items: false
  }
};

const sorted = Object.values(data).sort((a, b) => a.id - b.id);

console.log(sorted);

^{（我修复了对象文字，因为它在属性之间缺少逗号）}

您可以尝试！

function sort(data) 
{
   return Object.keys(data)
   .sort().reduce((a, b) => {
   a[b] = data[b];
   return a; }, {});
}

const object = {9:"Name 9", 10:"Name 10", 2:"Name 2", 5:"Name 5", 3:"Name 3"};
var sortObject = sort(abject);

结果是

sortObject = {2: "Name 2", 3: "Name 3", 5: "Name 5", 9: "Name 9", 10: "Name 10"}
