无法读取未定义 AngularJS 的 属性 'push'

Cannot read property 'push' of undefined AngularJS

我的目标是根据从 API 获得的数据创建一个数组。但是它一直向我显示 cannot read property 'push' of undefined Javascript.

的错误

谁能给我指明出路?

代码如下:

 myService.getData().then(function (res) {
            $scope.resoureceGroupsRawData = res.data;
            //declare an array already...
            $scope.resourceGroupItems = new Array();

        }, function(error) {
           throw error;
        }).then(function() {
            _.forEach($scope.resoureceGroupsRawData, function(text, idx) {
                var item = {};
                item.id = idx++;
                item.label = text;
                //why it says resourceGroupItems is null?
                $scope.resouceGroupItems.push(item);
            });
        }, function(err) {

        });

错别字兄弟, 你在几个地方拼错了资源。

myService.getData().then(function (res) {
            $scope.resourceGroupsRawData = res.data;
            //declare an array already...
            $scope.resourceGroupItems = new Array();

        }, function(error) {
           throw error;
        }).then(function() {
            _.forEach($scope.resourceGroupsRawData, function(text, idx) {
                var item = {};
                item.id = idx++;
                item.label = text;
                //why it says resourceGroupItems is null?
                $scope.resourceGroupItems.push(item);
            });
        }, function(err) {
            //TODO need add error page here
        });
