如何逆序收集订单

Question

根据按升序创建的日期对集合进行排序。怎么能按降序逆序排序？

var MyCollection = Backbone.Collection.extend({
    urlRoot: '/records',
    comparator: function(model) {
        return new Date(model.get('datecreated')).getTime();
    }
});

Answer 1

从比较器返回负值。

comparator: function(model) {
  return -new Date(model.get('datecreated')).getTime();
}
