Angular orderBy:'timestamp'把事情放错了

Question

我想做的事:

获取一个对象数组,每个对象以object.timestamp毫秒为单位,并从最新到最旧排序.

问题:

Angular的orderBy似乎没有按正确的顺序排列.以下时间戳按以下顺序排列:

1. 1416187808218 - // Nov/16/2014 5:30:PM
2. 1416187881192 - // Nov/16/2014 5:31:PM
3. 1416189118263 - // Nov/16/2014 5:51:PM
4. 1416189138827 - // Nov/16/2014 5:52:PM
5. 1416130064119 - // Nov/16/2014 1:27:AM

正确/期望的顺序显然是:

1. 1416189138827 - // Nov/16/2014 5:52:PM
2. 1416189118263 - // Nov/16/2014 5:51:PM
3. 1416187881192 - // Nov/16/2014 5:31:PM
4. 1416187808218 - // Nov/16/2014 5:30:PM
5. 1416130064119 - // Nov/16/2014 1:27:AM

所以它4, 3, 2, 1, 5应该是显而易见的,1, 2, 3, 4, 5

HTML:

<div class="cardWrapper" ng-repeat="card in cards | orderBy:'timestamp'">
  various child elements
</div>

JavaScript的:

scope.cards = homeData.get().cards; // returns an array of objects
// ^this^ becomes something similar to
scope.cards = [
  {text: 'some text...', timestamp: 1416189138827, other: 'data'},
  {text: 'some text...', timestamp: 1416187881192, other: 'data'}
  //etc...
];

您的时间戳是通过 API 作为字符串而不是整数吗？我意识到这里看起来不错。
