Javascript 在嵌套数组中获取不同的键

我有一个数组，我想得到所有不同的键。 我的json是这样的：

{

"odds": {
    "1_2": [
        {
            "id": 3355,
            "handicap": "1.25",

                "odds": "2.000",

            },
            "away_od": {

                "status": "same"
            }
        }
    ]

}}

我试图通过这种方式得到它们

  for (var i = 0; i < titles.length; i++) {
    var keys = [];
    for (var key in [titles[i]]) {
        keys.push(key);
    } 
    console.log(odds[titles[i]][keys[0]]);

for（变量i=0；i

我可以使用以下代码访问每个ojbect的id：[titles[i]][j].id

如何访问这些不同的密钥并在代码中显示它们？

例如，我想显示home\u od name，并显示其中包含的赔率和状态

集合是一种特殊类型的集合–“值集合”（无键）， 每个值只能出现一次。

Set

–是唯一值的集合

试试这个

Just call function findInObj and pass property name
