Question

我有一个ibject数组，每个元素内都有另一个对象，例如

data = [
  {
    name: "A",
    type: "AA",
    children: [ { id: 1, name: "Child-A", admin: ["Y"] }],
    other: "NA"
  },
  {
    name: "B",
    type: "BB",
    children: [ { id: 2, name: "Child-B" }],
    other: "NA"
  },
  {
    name: "C",
    type: "CC",
    children: [ { id: 3, name: "Child-C" }],
    other: "NA"
  }

]

我想按children.id值对整个集合进行排序，但要基于另一个数组给出的顺序

orderArray = [3, 1, 2]

所以输出将是

data =[
    {
        name: "C",
        type: "CC",
        children: [ { id: 3, name: "Child-C" }],
        other: "NA"
    },
    {
        name: "A",
        type: "AA",
        children: [ { id: 1, name: "Child-A", admin: ["Y"] }],
        other: "NA"
    },
    {
        name: "B",
        type: "BB",
        children: [ { id: 2, name: "Child-B" }],
        other: "NA"
    }
]

Answer 1

您可以将比较器传递给Array.sort，该比较器按index数组中children[0].id的{{1}}进行比较/排序

orderArray

Answer 2

尝试一下：

var newdataArray = []

orderArray.forEach(index => {
    newdataArray.push(data[index - 1])
});

data = newdataArray

如何按给定顺序在其他数组中对集合进行排序
