为了完整起见，这个函数返回对象属性的排序数组:

function sortObject(obj) {
    var arr = [];
    for (var prop in obj) {
        if (obj.hasOwnProperty(prop)) {
            arr.push({
                'key': prop,
                'value': obj[prop]
            });
        }
    }
    arr.sort(function(a, b) { return a.value - b.value; });
    //arr.sort(function(a, b) { return a.value.toLowerCase().localeCompare(b.value.toLowerCase()); }); //use this to sort as strings
    return arr; // returns array
}

var list = {"you": 100, "me": 75, "foo": 116, "bar": 15};
var arr = sortObject(list);
console.log(arr); // [{key:"bar", value:15}, {key:"me", value:75}, {key:"you", value:100}, {key:"foo", value:116}]

更新的小提琴排序字符串是在这里。您可以从它中删除额外的. tolowercase()转换，以便区分大小写的字符串比较。

你的对象可以有任意数量的属性，如果你把对象放在数组中，你可以选择根据你想要的任何对象属性进行排序，数字或字符串。考虑这个数组:

var arrayOfObjects = [   
    {
        name: 'Diana',
        born: 1373925600000, // Mon, Jul 15 2013
        num: 4,
        sex: 'female'
    },
    {

        name: 'Beyonce',
        born: 1366832953000, // Wed, Apr 24 2013
        num: 2,
        sex: 'female'
    },
    {            
        name: 'Albert',
        born: 1370288700000, // Mon, Jun 3 2013
        num: 3,
        sex: 'male'
    },    
    {
        name: 'Doris',
        born: 1354412087000, // Sat, Dec 1 2012
        num: 1,
        sex: 'female'
    }
];

按出生日期排序，最年长的先

// use slice() to copy the array and not just make a reference
var byDate = arrayOfObjects.slice(0);
byDate.sort(function(a,b) {
    return a.born - b.born;
});
console.log('by date:');
console.log(byDate);

按名称排序

var byName = arrayOfObjects.slice(0);
byName.sort(function(a,b) {
    var x = a.name.toLowerCase();
    var y = b.name.toLowerCase();
    return x < y ? -1 : x > y ? 1 : 0;
});

console.log('by name:');
console.log(byName);

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;
}

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
}

a = { b: 1, p: 8, c: 2, g: 1 }
Object.keys(a)
  .sort((c,b) => {
    return a[b]-a[c]
  })
  .reduce((acc, cur) => {
    let o = {}
    o[cur] = a[cur]
    acc.push(o)
    return acc
   } , [])

输出= [{p: 8}, {c: 2}, {b: 1}, {g: 1}]

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

function sortAssocObject(list) {
    var sortable = [];
    for (var key in list) {
        sortable.push([key, list[key]]);
    }
    // [["you",100],["me",75],["foo",116],["bar",15]]

    sortable.sort(function(a, b) {
        return (a[1] < b[1] ? -1 : (a[1] > b[1] ? 1 : 0));
    });
    // [["bar",15],["me",75],["you",100],["foo",116]]

    var orderedList = {};
    for (var idx in sortable) {
        orderedList[sortable[idx][0]] = sortable[idx][1];
    }

    return orderedList;
}

sortAssocObject(list);

// {bar: 15, me: 75, you: 100, foo: 116}
