另一种解决方法:-

var res = [{"s1":5},{"s2":3},{"s3":8}].sort(function(obj1,obj2){ 
 var prop1;
 var prop2;
 for(prop in obj1) {
  prop1=prop;
 }
 for(prop in obj2) {
  prop2=prop;
 }
 //the above two for loops will iterate only once because we use it to find the key
 return obj1[prop1]-obj2[prop2];
});

//res将有结果数组

一个过时问题的后续答案。我写了两个函数，一个是按键排序，另一个是按值排序，并在两个函数中以排序形式返回对象。它也应该在字符串上工作，因为这就是我张贴这个的原因(如果值不是数字的话，上面的一些按值排序有困难)。

const a = { absolutely: "works", entirely: 'zen', best: 'player', average: 'joe' } const prop_sort = obj => { return Object.keys(obj) .sort() .reduce((a, v) => { a[v] = obj[v]; return a; }, {}); } const value_sort = obj => { const ret = {} Object.values(obj) .sort() .forEach(val => { const key = Object.keys(obj).find(key => obj[key] == val) ret[key] = val }) return ret } console.log(prop_sort(a)) console.log(value_sort(a))

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);

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

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 });
