我想在父类的属性中选择数组。我不知道索引(在这种情况下是1),但我知道id。我可以做吗?这是我的索引工作示例,我想通过id(43)获得相同的结果。
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<div data-ng-app="myApp" data-ng-controller="myCtrl">
<ul>
<li ng-repeat="p in people[1].rooms" ng-bind="p"></li>
</ul>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.people = [
{
id: 25,
nick: 'Joker',
rooms: ['room1', 'room2']
},
{
id: 43,
nick: 'King',
rooms: ['room3', 'room4']
},
{
id: 78,
nick: 'Queen',
rooms: ['room5', 'room6']
}
]
});
</script>

您应该使用people
数组上的严格过滤器,按特定用户为特定用户分隔房间。显而易见的是,您将基于id
的搜索进行单个记录。

<ul>
<li ng-repeat="p in filteredPeople = (people | filter: {id: l.id })[0].rooms">
{{p}}
</li>
</ul>

这是一个选择:
<ul ng-repeat="p in people | filter: { id: 45 }">
<li ng-repeat="room in p.rooms" ng-bind="room"></li>
</ul>
