angularjs - 自定义属性变空

Question

我正在尝试unshift现有数组列表的对象。但是当我这样做时，我得到的值之一是empty。在angularjs中将新对象推送到现有数组的正确方法是什么？

这是我的代码：

 var staticPhase = {

                  "DisciplineId": "0",
                  "DisciplineName": "All",
                  "PhaseId": "0",
                  "PhaseName": "All" // but this is being converted as ''
                }

            if($scope.firstLoad) {

                var newList = angular.copy( $scope.project.ProjectSummaryFilter ); //taking a copy of existing array

                var filterById = $filter('filter')(newList, { ProjectId : $scope.projectId })[0];

                staticPhase.ProjectId = filterById.ProjectId;           
                staticPhase.ProjectName = filterById.ProjectName;           
                staticPhase.SubProjectId = filterById.SubProjectId;           
                staticPhase.SubProjectName = filterById.SubProjectName;  

            }


            var phaseList = $scope.project.ProjectSummaryFilter;
                            phaseList.unshift(staticPhase) //adding static phase to array;

标准JavaScript push()方法应该有效：

var phaseList = $scope.project.ProjectSummaryFilter;
phaseList.push(staticPhase);
