通过键获取对象，并保留它的键

Question

I am filtering data that looks like below with json[username] for example.

data looks like:

{"albert":{"userCData":[{"id":"slz1","checked":"false"},{"id":"slz2",...................]}}
{"sally":{"userCData":[{"id":"slz1","checked":"false"},{"id":"slz2",...................]}}
{"petey":{"userCData":[{"id":"slz1","checked":"false"},{"id":"slz2",...................]}}
{"gilbert":{"userCData":[{"id":"slz1","checked":"false"},{"id":"slz2",...................]}}

so, for instance json[sally] brings in sally data but omits her name (the key) giving me the below:

{"userCData":[{"id":"slz1","checked":"false"},{"id":"slz2",...................]}

I need to bring in/keep the name key as well. ie the whole line:

{"sally":{"userCData":[{"id":"slz1","checked":"false"},{"id":"slz2",...................]}}

If I hardcode it: user = "{" + username + ":"+json[username]+"}"; the object stops working: consoles as just {sally:[object Object]} . Anyway to achieve this?

Answer 1

You can loop over the json and try it in this way,

for(let item in json){
    let data = {};
    data[item] = json[item];
    console.log(data);
}

Answer 2

You can simply loop over the data like so:

for(var key in data){
    console.log(key);
    console.log(data[key]);
}

here, key will store the name sally, while data stored in sally is extracted via data[key].
