我想将每个 object 的不同数组值插入到 object 内的数组中

Question

I want to insert different array values per object into an array inside the object.

I have an arrayDetail object.

console.log(arrayDetail)

[
    {
        "content": "stackoverflow1",
        "type": "one"
        "appleId": undefined 
    },
    {
        "content": "stackoverflow2",
        "type": "two"
        "appleId": undefined 
    }
]

I have an applesIds array.

console.log(applesIds);

[49,50]

This is the result I want.
I tried a few times using map function or Object.fromEntries() function and looked up other stack overflow questions,
but I can't get it to work.

[
    {
        "content": "stackoverflow1",
        "type": "one"
        "appleId": 49 
    },
    {
        "content": "stackoverflow2",
        "type": "two"
        "appleId": 50 
    }
]

Answer 1

This would do the work

 let data = [ { "content": "stackoverflow1", "type": "one", "appleId": undefined }, { "content": "stackoverflow2", "type": "two", "appleId": undefined } ] let id = [49, 50] for(let i = 0; i < data.length; i++){ data[i]['appleId'] = id[i] } console.log(data)

Answer 2

You can use Array.map (use can use other Array iteration methods as well) and update the appleId like below

 const arrayDetail = [{ "content": "stackoverflow1", "type": "one", "appleId": undefined }, { "content": "stackoverflow2", "type": "two", "appleId": undefined } ] const appleIds = [49, 50]; const result = arrayDetail.map((item, index) => { return {...item, appleId: appleIds[index] } }); console.log(result);

Answer 3

Single liner code map always return array so i was returning array of object and put appleId with the help of index. index is 0,1,2 iteration so access id array with index

const mappedData = data.map((item, index) => ({ ...item, appleId: id[index] }));
