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

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!

我用sort的解决方案:

let list = {
    "you": 100, 
    "me": 75, 
    "foo": 116, 
    "bar": 15
};

let sorted = Object.entries(list).sort((a,b) => a[1] - b[1]);

for(let element of sorted) {
    console.log(element[0]+ ": " + element[1]);
}

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)

let toSort = {a:2323, b: 14, c: 799} 
let sorted = Object.entries(toSort ).sort((a,b)=> a[1]-b[1]) 

输出:

[ [ "b", 14 ], [ "c", 799 ], [ "a", 2323 ] ]

我为此做了一个插件，它接受1个arg，这是一个未排序的对象，并返回一个对象，已排序的道具值。这将适用于所有二维对象，如{"Nick": 28， "Bob": 52}…

var sloppyObj = {
    'C': 78,
    'A': 3,
    'B': 4
};

// Extend object to support sort method
function sortObj(obj) {
    "use strict";

    function Obj2Array(obj) {
        var newObj = [];
        for (var key in obj) {
            if (!obj.hasOwnProperty(key)) return;
            var value = [key, obj[key]];
            newObj.push(value);
        }
        return newObj;
    }

    var sortedArray = Obj2Array(obj).sort(function(a, b) {
        if (a[1] < b[1]) return -1;
        if (a[1] > b[1]) return 1;
        return 0;
    });

    function recreateSortedObject(targ) {
        var sortedObj = {};
        for (var i = 0; i < targ.length; i++) {
            sortedObj[targ[i][0]] = targ[i][1];
        }
        return sortedObj;
    }
    return recreateSortedObject(sortedArray);
}

var sortedObj = sortObj(sloppyObj);

alert(JSON.stringify(sortedObj));
