访问未知对象名称中的数据

Question

Let's say I have some JSON:

{
    "An unknown value": {
        "some": "values",
        "I": "want",
        "to": "access"
    }
}

As you can see, I want to access the data within an object with an unknown name. This code will run in a Node.js environment. Any help is appreciated.

https://jsfiddle.net/ygac8dgg/

var object = {
    "An unknown value": {
        "some": "values",
        "I": "want",
        "to": "access"
    },
    "Another":"is",
    "still":"uknown"
};

for (var property in object) {
    if (object.hasOwnProperty(property)) {
        // do stuff
        console.log("property:",property);
        console.log("value:",object[property]);
    }
}

Answer 2

For everyone's reference, here's RobG 's suggestion as a fiddle:
https://jsfiddle.net/m4jgyvp0

const object = {
   'An unknown value': {
      'some': 'values',
      'I':    'want',
      'to':   'access'
      },
   'Another': 'is',
   'still':   'unknown'
   };

const keys = Object.keys(object);
const array = keys.map(key => ({ key: key, value: object[key] }));

keys can be converted to an array of key-value pairs with the .map() function, or you could iterate over keys with .forEach() .

Answer 3

Reading my question again, it is very vague/unclear, and I can't seem to remember the context of this.

However in other situations, where I need to access an object via a dynamic key, one can use:

const key: string = "aKeyFromSomeWhere"
const value = object[key]

rather than object.aKnownKey
