调用其他对象内部的对象，MTGJSON

Question

恐怕又要挣扎了。我访问了一个名为MTG JSON (http://mtgjson.com/)的在线资源，这是一个json文件，其中包含每次打印的聚集卡的每个魔法的信息。

现在，我所拥有的信息是卡名，我想要获得多维宇宙的id。如果此信息位于AllCards.json文件中，这将非常简单，但是它存储在AllSets.json中，这意味着我需要对对象进行一些挖掘。

我对javascript非常陌生，所以走到这一步已经是相当大的成就了，但我完全被难住了，需要帮助。

所以，首先是代码。我现在已经想出了这个来阅读这个文件：

        $.getJSON("AllSets.json", function(json) {

            console.log(json); 

            Sets = Object.keys(json);
            i = 0;


            while (i < Sets.length){
                currentSet = Sets[i];
                console.log(json.currentSet);
                console.log(currentSet);
                console.log(i);
                i = i + 1;

            }


        });

我已经开始在集合中移动，以便通过名字找到我当前所在的卡片。

问题是以下三行：

                console.log(json.currentSet);

                console.log(currentSet);

                console.log(i);

这些是最让我头疼的，因为我和currentSet都做得很好，返回当前集合和列表中该集合的当前位置。但是，json.currentSet将以undefined的形式返回。

对于那些对JSON结构感兴趣的人：

任何反馈、批评、建议等都将非常感谢，因为每次我认为我走了一英里，我就会看到前面还有10英里。

为什么不使用这样的东西呢？

cards.forEach(function(e){
   if(e.name == "myName")
      console.log(e.multiverseid);
});
