javascript - 如何使用angular js显示对象数组的分组

Question

我有对象数组，但我不知道如何按 id 顺序分组。我想使用 ng-repeat 显示它的数字顺序，如 1,2,3

$scope.arrayofobject=[{name:"testMachne","id":1},{name:"testComputer","id":2},{name:"testCalc","id":3},{name:"testMac","id":2},{name:"testMachne","id":3},{name:"testMachne","id":1}]

您可以使用 orderBy 过滤器:

angular.module('app',[]).controller('mainCtrl', function($scope){
     $scope.arrayofobject=[{name:"testMachne","id":1},{name:"testComputer","id":2},{name:"testCalc","id":3},{name:"testMac","id":2},{name:"testMachne","id":3},{name:"testMachne","id":1}];
})

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app='app' ng-controller='mainCtrl'>
   
    <div ng-repeat="json in arrayofobject | orderBy:'id' " ng-if='json.id !== 1'>
       {{json.name}}
    </div>
</div>
