Question

我希望解析一个json url /文件，只获取json中的顶级节点。

json对象如下所示：

{
"2017080350": {
    "home": {
        "score": {
            "1": null,
            "2": null,
            "3": null,
            "4": null,
            "5": null,
            "T": null
        },
        "abbr": "ARI",
        "to": null
    },
    "away": {
        "score": {
            "1": null,
            "2": null,
            "3": null,
            "4": null,
            "5": null,
            "T": null
        },
        "abbr": "DAL",
        "to": null
    },
    "bp": 0,
    "down": null,
    "togo": null,
    "clock": null,
    "posteam": null,
    "note": null,
    "redzone": null,
    "stadium": "Tom Benson Hall of Fame Stadium",
    "media": {
        "radio": {
            "home": null,
            "away": null
        },
        "tv": "NBC",
        "sat": null,
        "sathd": null
    },
    "yl": null,
    "qtr": null
},
"2017080351": {
    "home": {
        "score": {
            "1": null,
            "2": null,
            "3": null,
            "4": null,
            "5": null,
            "T": null
        },
        "abbr": "ARI",
        "to": null
    },
    "away": {
        "score": {
            "1": null,
            "2": null,
            "3": null,
            "4": null,
            "5": null,
            "T": null
        },
        "abbr": "DAL",
        "to": null
    },
    "bp": 0,
    "down": null,
    "togo": null,
    "clock": null,
    "posteam": null,
    "note": null,
    "redzone": null,
    "stadium": "Tom Benson Hall of Fame Stadium",
    "media": {
        "radio": {
            "home": null,
            "away": null
        },
        "tv": "NBC",
        "sat": null,
        "sathd": null
    },
    "yl": null,
    "qtr": null
}
}

我想要得到的是两个值2017080350和2017080351 我可以正常阅读和显示内容，但在尝试获取两个提到的节点时遇到问题？

如果您的回复尚未解析，请先执行以下操作：

response = JSON.parse(response);

然后你可以使用for...in循环：

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

要读取链接到该键的数据，您可以像这样展开：

for (let key in response) {
     console.log(key);
     let value = response[key];
     // and you can go deeper...
     for (let deeperKey in value) {
         // ...etc.
     }
}
