Javascript 为什么我的函数得到0个结果？

嘿，我这里有3个函数一起工作。但问题是最后一个被称为doesn的数组并没有遍历它，因为它看到的是一个空数组。有趣的是，当我执行

console.log（）

整个对象时，它在该数组中有一个数据，但当我只记录该对象中的数组元素时，它是空的。为什么?

这是一支密码笔：

下面是它的样子：

getPlacesInArea: function($scope, types, callback) {
    for (var key in types) {
        if (types.hasOwnProperty(key) && types[key].checked) {
            this.getPlace($scope, key);
        }
    }
    callback($scope);
},

所以这里发生的事情就是我将数据从api加载到范围VARABLE

getAttractionsInArea: function($scope, typesValue) {
    placesService.getPlacesInArea($scope, typesValue, this.showAttractionMarkers);
},
showAttractionMarkers: function($scope) {
    placesService.showPlacesMarkers($scope.map, $scope.attractionsMarkers);
}

这里是调用

getPlacesInArea

的位置。 在

getAttractionsInArea

中，我还将其作为回调

showAttractionMarkers

方法传递

showPlacesMarkers: function(map, markers) {
    if (typeof map != 'undefined') {
        for (var key in markers) {
            if (markers.hasOwnProperty(key)) {
                mapService.setMapForMarkers(markers[key].items, map);
            }
        }
    } else {
        for (var type in markers) {
            if (markers.hasOwnProperty(type)) {
                mapService.setMapForMarkers(markers[type].items, null);
            }
        }
    }
},

如果我执行

console.log（markers）

我看到markers[type].items有items，那么我们就在这个函数中了。但是如果我执行

console.log（markers[type].items）

则数组为空。为什么呢？我怎样才能修好它

这里是

console.log（标记）

这是食物对象的例子
