在angularjs中調用json數組

Question

我有一個json數組

[{
"id": "21390238becde1290",
"chelsea": {
    "homeTeam": "chelsea",
    "sortName": "ches",
    "awayTeam": "Maribor",
    "awayShort": ""
},
"barclays": {
    "id": "21390238becde1290",
    "homeTeam": "barclays",
    "sortName": "barc",
    "awayTeam": "Hull",
    "awayShort": ""
}
}]

控制器：

footBallApp.controller('TeamInfoEdit',
    function ($rootScope, $scope, $state, $translate, carwashService) {

        $rootScope.washTypes;

        $scope.onViewLoaded = function () {
           matchService.getTeamTypes($scope.TypeSelected);
        }

        $scope.TypeSelected = function (response) {
            debugger;
            if (response) {
                $rootScope.teamAvailable = response;
                $scope.localizedTeamName = getLocalizedCollection($scope.teamAvailable);
            }
        }

        // Editing the Team Details.

        $scope.editTeamDetails = function (key) {
            console.log(key._id);

            $rootScope.selectTeam =[]; 
            for(var i=0; i<$scope.teamAvailable.length;i++){
            if($scope.teamAvailable[i]._id== key._id)
            {
                console.log($scope.teamAvailable[i]);
                $scope.selectTeam.push($scope.teamAvailable[i]);
                debugger;

我已經將數組分配給$scope.selectTeam 。 當我試圖調用$scope.selectTeam.chelsea ，在控制台中將其獲取為Undefined 。 在調用json我出錯了，但是找不到，所以如何正確調用數組。 因此，在此尋求幫助。

Answer 1

我不知道您的數組是什么樣子，但是嘗試調用：

$scope.selectTeam[0].chelsea

Answer 2

由於未初始化，數組即將到來。 如果您初始化$ rootScope.teamAvailable = {}; 那么如果響應數據為json格式，它將被覆蓋。
