How do you retrieve the ID of an object from a JSON request?

Looking to retrieve the first object from this dynamic list:

{
"2489": {
    "status": {
        "idstatus": "3",
        "status": "Sold"
    }
},

"2490": {
    "status": {
        "idstatus": "3",
        "status": "Sold"
    }
}

}

The specific IDs ['2489'] and ['2490'] are unknown beforehand. The response may include varying numbers of these IDs.

How can I access ['2490'].status.idstatus without prior knowledge of the ID ['2490']?

Answer №1

You have the option to utilize either Object.values and map, or if you require the key, you can make use of Object.entries

const data = {
"2489": {
    "status": {
        "idstatus": "3",
        "status": "Sold"
    }
},

"2490": {
    "status": {
        "idstatus": "3",
        "status": "Sold"
    }
}
}

const statusIds = Object.values(data).map(d => d.status.idstatus)
console.log(statusIds)

const statusIdAndKey = Object.entries(data).map(([k, d]) => [k, d.status.idstatus])
console.log(statusIdAndKey)

Answer №2

There are numerous methods to achieve this task. In a modern JS environment, you have the option to utilize Object.keys or Object.values.

If your JSON response object is stored in a variable named res, you can create a dynamic array of IDs like so:

const ids = Object.keys(res) // ["2489", "2490", ...]

If the IDs are irrelevant and you prefer an array containing all the inner objects, you can try this approach:

const items = Object.values(res) // [ { "status" : ... }, ... ]
