谢谢你，继续回答@Nosredna

现在我们知道对象需要转换为数组，然后对数组排序。这对于按字符串排序数组(或转换对象为数组)非常有用:

Object {6: Object, 7: Object, 8: Object, 9: Object, 10: Object, 11: Object, 12: Object}
   6: Object
   id: "6"
   name: "PhD"
   obe_service_type_id: "2"
   __proto__: Object
   7: Object
   id: "7"
   name: "BVC (BPTC)"
   obe_service_type_id: "2"
   __proto__: Object


    //Sort options
    var sortable = [];
    for (var vehicle in options)
    sortable.push([vehicle, options[vehicle]]);
    sortable.sort(function(a, b) {
        return a[1].name < b[1].name ? -1 : 1;
    });


    //sortable => prints  
[Array[2], Array[2], Array[2], Array[2], Array[2], Array[2], Array[2]]
    0: Array[2]
    0: "11"
    1: Object
        id: "11"
        name: "AS/A2"
        obe_service_type_id: "2"
        __proto__: Object
        length: 2
        __proto__: Array[0]
    1: Array[2]
    0: "7"
    1: Object
        id: "7"
        name: "BVC (BPTC)"
        obe_service_type_id: "2"
        __proto__: Object
        length: 2

const arrayOfObjects = [
{name: 'test'},
{name: 'test2'}
]

const order = ['test2', 'test']

const setOrder = (arrayOfObjects, order) =>
    arrayOfObjects.sort((a, b) => {
        if (order.findIndex((i) => i === a.name) < order.findIndex((i) => i === b.name)) {
            return -1;
        }

        if (order.findIndex((i) => i === a.name) > order.findIndex((i) => i === b.name)) {
            return 1;
        }

        return 0;
    });

以防万一，有人正在寻找保持对象(键和值)，使用@Markus R和@James Moran注释的代码引用，只需使用:

var list = {"you": 100, "me": 75, "foo": 116, "bar": 15};
var newO = {};
Object.keys(list).sort(function(a,b){return list[a]-list[b]})
                 .map(key => newO[key] = list[key]);
console.log(newO);  // {bar: 15, me: 75, you: 100, foo: 116}

JavaScript对象根据定义是无序的(参见ECMAScript语言) 规范，第8.6节)。语言规范甚至不能保证，如果你连续迭代一个对象的属性两次，第二次它们会以相同的顺序出现。

如果你需要对事物进行排序，可以使用数组和array .prototype.sort方法。

对象按值排序(DESC)

function sortObject(list) {
  var sortable = [];
  for (var key in list) {
    sortable.push([key, list[key]]);
  }

  sortable.sort(function(a, b) {
    return (a[1] > b[1] ? -1 : (a[1] < b[1] ? 1 : 0));
  });

  var orderedList = {};
  for (var i = 0; i < sortable.length; i++) {
    orderedList[sortable[i][0]] = sortable[i][1];
  }

  return orderedList;
}

感谢@orad在TypeScript中提供了答案。现在，我们可以在JavaScript中使用下面的代码片断。

function sort(obj,valSelector) { const sortedEntries = Object.entries(obj) .sort((a, b) => valSelector(a[1]) > valSelector(b[1]) ? 1 : valSelector(a[1]) < valSelector(b[1]) ? -1 : 0); return new Map(sortedEntries); } const Countries = { "AD": { "name": "Andorra", }, "AE": { "name": "United Arab Emirates", }, "IN": { "name": "India", }} // Sort the object inside object. var sortedMap = sort(Countries, val => val.name); // Convert to object. var sortedObj = {}; sortedMap.forEach((v,k) => { sortedObj[k] = v }); console.log(sortedObj); //Output: {"AD": {"name": "Andorra"},"IN": {"name": "India"},"AE": {"name": "United Arab Emirates"}}
