How to insert an object into an array which is inside an object?-CodePudding

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"
    }
  ]
]

CodePudding user response：

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 } ] ]

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?
