下面的函数根据值或值的属性对对象进行排序。如果你不使用TypeScript，你可以删除类型信息，将其转换为JavaScript。

/**
 * Represents an associative array of a same type.
 */
interface Dictionary<T> {
  [key: string]: T;
}

/**
 * Sorts an object (dictionary) by value or property of value and returns
 * the sorted result as a Map object to preserve the sort order.
 */
function sort<TValue>(
  obj: Dictionary<TValue>,
  valSelector: (val: TValue) => number | string,
) {
  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);
}

使用

var list = {
  "one": { height: 100, weight: 15 },
  "two": { height: 75, weight: 12 },
  "three": { height: 116, weight: 9 },
  "four": { height: 15, weight: 10 },
};

var sortedMap = sort(list, val => val.height);

JavaScript对象中键的顺序是不保证的，所以我将排序并将结果返回为一个保留排序顺序的Map对象。

如果你想把它转换回Object，你可以这样做:

var sortedObj = {} as any;
sortedMap.forEach((v,k) => { sortedObj[k] = v });

下划线。js或Lodash.js用于高级数组或对象排序

var data = { "models": { "LTI": [ "TX" ], "Carado": [ "A", "T", "A(пасс)", "A(груз)", "T(пасс)", "T(груз)", "A", "T" ], "SPARK": [ "SP110C 2", "sp150r 18" ], "Autobianchi": [ "A112" ] } }; var arr = [], obj = {}; for (var i in data.models) { arr.push([i, _.sortBy(data.models[i], function(el) { return el; })]); } arr = _.sortBy(arr, function(el) { return el[0]; }); _.map(arr, function(el) { return obj[el[0]] = el[1]; }); console.log(obj); <script src="https://cdn.jsdelivr.net/npm/lodash@4.17.21/lodash.min.js" integrity="sha256-qXBd/EfAdjOA2FGrGAG+b3YBn2tn5A6bhz+LSgYD96k=" crossorigin="anonymous"></script>

<pre>
function sortObjectByVal(obj){  
var keysSorted = Object.keys(obj).sort(function(a,b){return obj[b]-obj[a]});
var newObj = {};
for(var x of keysSorted){
    newObj[x] = obj[x];
}
return newObj;

}
var list = {"you": 100, "me": 75, "foo": 116, "bar": 15};
console.log(sortObjectByVal(list));
</pre>

找出每个元素的频率，并按频率/值进行排序。

Let response =["苹果"，"橘子"，"苹果"，"香蕉"，"橘子"，"香蕉"，"香蕉"]; 设frequency = {}; response.forEach(函数(项){ 频率[项目]=频率[项目]?频率[项]+ 1:1; })； console.log(频率); let intents = Object.entries(frequency) .sort((a, b) => b[1] - a[1]) . map(函数(x) { 返回x [0]; })； console.log(意图);

输出:

{ apple: 2, orange: 2, banana: 3 }
[ 'banana', 'apple', 'orange' ]

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

我已经用自己的方式尝试过了

var maxSpeed = {
  car: 300, 
  bike: 60, 
  motorbike: 200, 
  airplane: 1000,
  helicopter: 400, 
  rocket: 8 * 60 * 60
};
var sorted = {}
 Object.keys(maxSpeed).sort ((a,b) => maxSpeed[a] - maxSpeed[b]).map(item => sorted[item] = maxSpeed[item]);
console.log(sorted)
