我需要将它嵌套在他们的地方。等于＆＃34; folder_id＆＃34;和＆＃34; origin_id＆＃34;
我尝试使用：
$scope.arr.map(function(el){
el.items = $scope.arr.filter(function(item){
return item.folder_id === el.id
});
return el;
}).filter(function(item){
return item.folder_id === null;
})
但是控制台给了我以下错误并停止工作。
TypeError: Converting circular structure to JSON
请帮助!!

分配给一些新阵列
$scope.nestArray = $scope.arr.map(function(el){
el.items = $scope.arr.filter(function(item){
return item.folder_id === el.id
});
return el;
}).filter(function(item){
return item.folder_id === null;
})
console.log($scope.nestArray);
var myApp = angular.module('myApp',[]);
function LoginController($scope) {
$scope.name = 'Superhero';
$scope.arr = [
