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

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;
}

.sort((a,b) => daySorterMap[a] - daySorterMap[b])

你可以返回sortedDayObj

<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>

这里还有一个例子:

函数sortObject(obj) { Var arr = []; var支撑; For (prop in obj) { if (obj.hasOwnProperty(prop)) { arr.push ({ “关键”:道具, “价值”:obj(道具) })； ｝ ｝ 加勒比海盗。排序(函数(a, b) { 返回a.value - b.value; })； 返回arr;//返回数组 ｝ Var列表= { 车:300, 自行车:60岁 摩托车:200, 飞机:1000, 直升机:400, 火箭:8 * 60 * 60 }; var arr = sortObject(list); console.log (arr);

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)
