我正从远程源检索2个JSON数组。我正在尝试将结果从数组X过滤到数组Y,并且只返回两者中的唯一值。 stackoverflow上的所有问题都是用于过滤1个数组而不是一组多个。
答案 0 :(得分:1)
您可以使用与a8m/angular-filter
中的unique
过滤器类似的内容
(function() {
angular.module('myApp', ['angular.filter'])
.controller('HomeController', ['$scope',
function($scope) {
$scope.first = [{id: 1, name:'first'},{id: 2, name:'second'},
{id: 3, name:'third'}, {id: 4, name: 'fourth'} ];
$scope.second = [{id: 1, name:'first'},{id: 2, name:'second'},
{id: 5, name: 'fifth'} ];
}
]);
}());

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-filter/0.5.1/angular-filter.min.js"></script>
<div ng-app="myApp">
<div ng-controller="HomeController">
<ul>
<li ng-repeat="item in first.concat(second) | unique:'id'">
{{item.id}} : {{ item.name }}
</li>
</ul>
</div>
</div>
