遍历匿名对象

Question

我有以下包含数组的对象：

​

我正在对它进行迭代，以获得它的键值，就像进一步使用它一样，使用for in来获取其中的数据。

for (let key in gameObj){
    console.log(key);
}

但是为了得到数组，它甚至没有进入循环。

我错过了什么？

Answer 1

我会加上这条评论，但还没有这个名气。请参阅Is it possible to get the non-enumerable inherited property names of an object?

function getAllProperties(obj){
    var allProps = []
      , curr = obj
    do{
        var props = Object.getOwnPropertyNames(curr)
        props.forEach(function(prop){
            if (allProps.indexOf(prop) === -1)
                allProps.push(prop)
        })
    }while(curr = Object.getPrototypeOf(curr))
    return allProps
}

Answer 2

它工作得很好。检查一下小提琴。

​

    var gameObj = {
    "key1" : ["1","1","1","1","1","1","1"],
    "key2": ["2","2","2","2","2","2","2","2","2","2",]
    }
    
    for(var i in gameObj){
    alert(i);
    }

Answer 3

如果你想访问for循环中的对象，key将是关键，那么你只需要像调用数组一样调用它：

​

const gameObj = {
   '99lEEbmV7s': ['37966', '37966', '37965', '37966', '0'],
   'TggZdsbcje': ['37966', '37966', '37965', '37966', '0']
};

for (let key in gameObj){
    console.log(gameObj[key]);
}
