javascript - Angular 中的数组映射

Question

我的 JSON 对象

$scope.selectedItems ={
    "RECORDS": [
        {
            "Id": 23040035705987,
            "arriveddate": "2015/04/24",
            "expirationDate": null,
            "replacedDate": null,
            "processDate": "2015/04/24"
        },
        {
            "Id": 23070041800654,
            "arriveddate": "2015/04/24",
            "expirationDate": null,
            "replacedDate": null,
            "processDate": "2015/04/27"
        },
        {
            "Id": 23040035705984,
            "arriveddate": "2015/04/24",
            "expirationDate": null,
            "replacedDate": null,
            "processDate": "2015/04/24"
        },
        {
            "Id": 23040035705983,
            "arriveddate": "2015/04/24",
            "expirationDate": null,
            "replacedDate": null,
            "processDate": "2015/04/24"
        }
    ]
}

我在做什么

对于我拥有的每个唯一流程日期，我需要在下面提到的对象中的单独对象中的相应 ID，流程日期 24/04/2015 与以 83、84、87 结尾的 ID 和流程日期 27/04 匹配/2015 匹配以54结尾的id

我期望的 JSON 对象

{
    "processDate": [
        "2015/04/24",
        "2015/04/27"
    ],
    "Id": [
        [
            23040035705983,
            23040035705984,
            23040035705987
        ],
        [
            23070041800654
        ]
    ]
}

我在努力

angular.forEach($scope.selectedItems.RECORDS, function ( item ) { 
                $scope.ProcessDate = item.processDate;
                if($scope.processDatesSelected.indexOf($scope.ProcessDate) == -1){
                  $scope.processDatesSelected.push($scope.ProcessDate);
                }

                if($scope.processDatesSelected.indexOf($scope.ProcessDate) != -1 && $scope.id.indexOf(item.Id) == -1 ){
                    $scope.id.push(item.Id);
                }

            });

  $scope.changesSelected.push({processDate:$scope.processDatesSelected,Ids:$scope.id});
  console.log(JSON.stringify($scope.changesSelected));

问题是 id 没有相应地映射，我已经为它创建了一个 plunker (http://plnkr.co/edit/mkLXdOKayaqyDDDheFeu?p=preview)任何帮助将不胜感激。

尝试这种方式:http://plnkr.co/edit/LS40YJR9X0OAqBTIP2lZ?p=preview

angular.forEach($scope.selectedItems.RECORDS, function ( item ) { 
            $scope.ProcessDate = item.processDate;
            var i=$scope.processDatesSelected.indexOf($scope.ProcessDate);
            if(i == -1){
              i=$scope.processDatesSelected.length;
              $scope.processDatesSelected.push($scope.ProcessDate);
              $scope.id[i]=[];
            }

            if(i != -1 && $scope.id[i].indexOf(item.Id) == -1 ){
                $scope.id[i].push(item.Id);
            }

        });
