我有一个像这样的对象数组:
$scope.cars = [
{"brand":"McLaren","price":70,"stock":0},
{"brand":"Renault","price":10,"stock":0},
{"brand":"Ferrari","price":100,"stock":3},
{"brand":"Lamborghini","price":50,"stock":2},
{"brand":"Porsche","price":30,"stock":1},
{"brand":"Seat","price":120,"stock":0},
{"brand":"Audi","price":10,"stock":3},
];
我想在 Angular 中按照我的观点从高价到低价对它们进行排序，但保留最后有 "stock":0 的那些。有没有什么直接的方法可以用 Angular 来做到这一点？这是一个working plunker以我为例。谢谢!
最佳答案
放弃比较器功能，我们可以按“stock == 0”排序，因为按字符串排序是 Angular 表达式。这比我最初的比较器解决方案简单得多。
`orderBy:['stock==0','-price']`
