如何将 object 插入到 object 内的数组中？

Question

Suppose if we are having data like this, how can we use dot notations or anything to update the array(data2) inside the object data1 which is inside the array(data).

data = [
data1:
    {
        a:"1",
        b:"2"
    }
]

    // another array(data2 - below) I am having I have to push that array inside 
    data1 as an object
data2 = [
    {
        c:"3"
    },
    {
        d:"4"
    }
    ]

The response I want as below:

    data = [
data1:
    {
        a:"1",
        b:"2"
    },
data2 = [
    {
        c:"3"
    },
    {
        d:"4"
    }
  ]
]

Answer 1

I didnt really understand your question but i think this is what you want?!

data = {
    data1:
    {
        a: "1",
        b: "2"
    }
}
data2 = [
    {
        c: "3"
    },
    {
        a: "3"
    },
    {
        d: "4"
    }
]

for (var key in data2) {
    for (var key2 in data2[key]) {
        if(data.data1[key2] != null){
            console.log("data.data1 with they key" + key2 + " could have been replaced/updated with " + data2[key][key2]);
        }
        console.log("key " + key2 + " has value " + data2[key][key2]);
    }
}

Result:

key c has value 3 data.data1 with they keya could have been replaced/updated with 3 key a has value 3 key d has value 4

Edit:

Why dont you just do

data["data2"] = data2?

Answer 2

---

var array = [];

array['data1'] = { 'name': 'a' }

var array2 = [{ c: 3 }, { d: 4 }];

array['data2'] = array2;

console.log(array)

OutPut:

[ data1: { name: 'a' }, data2: [ { c: 3 }, { d: 4 } ] ]

Answer 3

I tried on myself and I got the solution. If we have to make another field in an object you just give a name like this

data.dataTwo

this will create another field with new name and now if we want to transfer or store an array in this we can simply do this

data.dataTwo = data2

This will assign that data2 named array in a new field what is given as dataTwo
