Question

function ($scope, $stateParams, $http, WineService, $rootScope) {

var wineList = [];
getAllWineIDsOfEvent();
setAttributesOfWine();

function getAllWineIDsOfEvent() {
    var wineIDofEvent = $($scope.tableEntries_AT_Event_Wine).filter(function (i, n) { return n.Event_ID === $scope.actEvent; });
    wineList = [];
    for (var i = 0; i < wineIDofEvent.length; i++) {
        var Wine = { id: wineIDofEvent[i].Wine_ID };
        wineList.push(Wine);
    }

}

//set missing Attributes of Wine
function setAttributesOfWine() {

    for (var i = 0; i < $scope.tableEntries_wine.length; i++) {
        var wineofEvent = $($scope.tableEntries_wine).filter(function (i, n) { return n.id === wineList[i].id; });
    }

    $rootScope.WineOfEvent = wineList;
}}])

我每次要过滤$scope.tableEntries_wine时都会收到Cannot read property 'id' of undefined错误。

我认为这与我的$scope.tableEntries_wine有关。这是它的样子：

当我将$scope.tableEntries_wine替换为具有属性ID的另一个表时，我不会收到错误。

wineList看起来像这样：

[{
    "id": "a66f426e-8466-42b6-bda5-86e39bb3b708"
},
{
    "id": "9ab3d9c4-f2ff-4547-8a4b-883fd78a3842"
},
{
    "id": "3b920bfa-f549-474c-beca-1384503af421"
}]

有人有想法吗？
