Angularjs 过滤器嵌套对象

Question

我有这样的 Angular 嵌套对象。有没有办法过滤它的嵌套属性

<li ng-repeat="shop in shops | filter:search">
search.locations.city_id = 22

我只显示父元素，但想按这两个元素进行过滤，例如:

search = 
  category_id: 2
  locations:
    city_id: 368

[
 name: "xxx"
 category_id: 1
 locations: [
   city_id: 368
   region_id: 4
  ,
   city_id: 368
   region_id: 4
  ,
   city_id: 368
   region_id: 4
  ]
,
 name: "xxx"
 category_id: 2
 locations: [
   city_id: 30
   region_id: 4
  ,
   city_id: 22
   region_id: 2
  ]
]

Answer 1

您也可以这样过滤(版本1.2.13+)

<li ng-repeat="shop in shops | filter: { locations: [{ city_id: search.locations.city_id }] }">
