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));

许多类似和有用的功能: https://github.com/shimondoodkin/groupbyfunctions/

function sortobj(obj)
{
    var keys=Object.keys(obj);
    var kva= keys.map(function(k,i)
    {
        return [k,obj[k]];
    });
    kva.sort(function(a,b){
        if(a[1]>b[1]) return -1;if(a[1]<b[1]) return 1;
        return 0
    });
    var o={}
    kva.forEach(function(a){ o[a[0]]=a[1]})
    return o;
}

function sortobjkey(obj,key)
{
    var keys=Object.keys(obj);
    var kva= keys.map(function(k,i)
    {
        return [k,obj[k]];
    });
    kva.sort(function(a,b){
        k=key;      if(a[1][k]>b[1][k]) return -1;if(a[1][k]<b[1][k]) return 1;
        return 0
    });
    var o={}
    kva.forEach(function(a){ o[a[0]]=a[1]})
    return o;
}

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;
}

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}

<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>

打印稿

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 });
