下面是工作代码

var list = { "you": 100, "me": 75, "foo": 116, "bar": 15 }; var sortArray = []; // convert the list to array of key and value pair for(let i in list){ sortArray.push({key : i, value:list[i]}); } //console.log(sortArray); // sort the array using value. sortArray.sort(function(a,b){ return a.value - b.value; }); //console.log(sortArray); // now create a newList of required format. let newList={}; for(let i in sortArray){ newList[sortArray[i].key] = sortArray[i].value; } console.log(newList);

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>

另一个关于Object的例子。值、sort()和展开运算符。

var paintings = {
    0: {
        title: 'Oh my!',
        year: '2020',
        price: '3000'
    },
    1: {
        title: 'Portrait V',
        year: '2021',
        price: '2000'
    },
    2: {
        title: 'The last leaf',
        year: '2005',
        price: '600'
    }
}

我们使用object .values将对象转换为对象数组:

var toArray = Object.values(paintings)

然后我们对数组进行排序(按年份和价格)，使用spread操作符使原始数组不可变，并使用sort()方法对数组进行排序:

var sortedByYear = [...toArray].sort((a, b) => a.year - b.year)
var sortedByPrice = [...toArray].sort((a, b) => a.price - b.price)

最后，我们生成新的排序对象(同样，使用展开运算符来保持以[x: number]为键的对象的object的原始形式):

var paintingsSortedByYear = {
    ...sortedByYear
}

var paintingsSortedByPrice = {
    ...sortedByPrice
}

希望这对你有所帮助!

我们不想复制整个数据结构，也不想在需要关联数组的地方使用数组。

这里有另一种方法来做与bonna相同的事情:

var列表={“我”“你”:100:75年,“foo”:116年,“酒吧”:15}; keysSorted = Object.keys(list).sort(function(a,b){返回list[a]-list[b]}) console.log (keysSorted);/ /酒吧,我,你,foo

输入是对象，输出是对象，使用lodash & js内置库，降序或升序选项，不改变输入对象

Eg输入输出

{
  "a": 1,
  "b": 4,
  "c": 0,
  "d": 2
}
{
  "b": 4,
  "d": 2,
  "a": 1,
  "c": 0
}

实现

const _ = require('lodash');

const o = { a: 1, b: 4, c: 0, d: 2 };


function sortByValue(object, descending = true) {
  const { max, min } = Math;
  const selector = descending ? max : min;

  const objects = [];
  const cloned = _.clone(object);

  while (!_.isEmpty(cloned)) {
    const selectedValue = selector(...Object.values(cloned));
    const [key, value] = Object.entries(cloned).find(([, value]) => value === selectedValue);

    objects.push({ [key]: value });
    delete cloned[key];
  }

  return _.merge(...objects);
}

const o2 = sortByValue(o);
console.log(JSON.stringify(o2, null, 2));

我遵循slebetman给出的解决方案(去阅读它的所有细节)，但调整，因为你的对象是非嵌套的。

// First create the array of keys/values so that we can sort it:
var sort_array = [];
for (var key in list) {
    sort_array.push({key:key,value:list[key]});
}

// Now sort it:
sort_array.sort(function(x,y){return x.value - y.value});

// Now process that object with it:
for (var i=0;i<sort_array.length;i++) {
    var item = list[sort_array[i].key];

    // now do stuff with each item
}
