如果我有一个JavaScript对象,如:

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

是否有一种方法可以根据值对属性进行排序?最后得到

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

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>

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}

如果我有一个这样的对象,

var dayObj = {
              "Friday":["5:00pm to 12:00am"] ,
              "Wednesday":["5:00pm to 11:00pm"],
              "Sunday":["11:00am to 11:00pm"], 
              "Thursday":["5:00pm to 11:00pm"],
              "Saturday":["11:00am to 12:00am"]
           }

我想按天排序,

我们应该先有daySorterMap,

var daySorterMap = {
  // "sunday": 0, // << if sunday is first day of week
  "Monday": 1,
  "Tuesday": 2,
  "Wednesday": 3,
  "Thursday": 4,
  "Friday": 5,
  "Saturday": 6,
  "Sunday": 7
}

初始化一个单独的对象sortedDayObj,

var sortedDayObj={};
Object.keys(dayObj)
.sort((a,b) => daySorterMap[a] - daySorterMap[b])
.forEach(value=>sortedDayObj[value]= dayObj[value])

你可以返回sortedDayObj

使用query-js你可以这样做

list.keys().select(function(k){
    return {
        key: k,
        value : list[k]
    }
}).orderBy(function(e){ return e.value;});

你可以在这里找到一篇关于query-js的介绍性文章

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;
}
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;
    });
