使用这段代码它工作正常！

return c-d;
});

1) You can't sort objects. The order of the object's keys is arbitrary.
1) 您不能对对象进行排序。对象键的顺序是任意的。
2) If you want to sort an array by date (and they are already date obects), do the following:
2) 如果要按日期对数组进行排序（并且它们已经是日期对象），请执行以下操作：
array.sort ( function (date1, date2){
return date1 - date2
});
If you first need to convert them to date objects, do the following (following the data structure according to your comment below):
如果您首先需要将它们转换为日期对象，请执行以下操作（根据您下面的评论遵循数据结构）：
array.sort ( function (a, b){
return new Date(a.pubDate) - new Date(b.pubDate);
});

You may also use a underscore/lodash sortBy
你也可以使用下划线/lodash sortBy
Here's using underscore js to sort date:
这里使用下划线 js 对日期进行排序：
var log = [{date: '2016-01-16T05:23:38+00:00', other: 'sample'},
{date: '2016-01-13T05:23:38+00:00',other: 'sample'},
{date: '2016-01-15T11:23:38+00:00', other: 'sample'}];
console.log(_.sortBy(log, 'date'));

sorting dates ascending or descending
times = ["01-09-2013", "01-09-2013", "27-08-2013", "27-08-2013", "28-08-2013", "28-08-2013", "28-08-2013", "28-08-2013", "29-08-2013", "29-08-2013", "30-08-2013", "30-08-2013", "31-08-2013", "31-08-2013"]
function dmyOrdA(a,b){ return myDate(a) - myDate(b);}
function dmyOrdD(a,b){ return myDate(b) - myDate(a);}
function myDate(s){var a=s.split(/-|\//); return new Date(a[2],a[1]-1,a[0]);}
times.sort(dmyOrdA);
console.log(times)
