How to set an object inside an object?

Question

I have two object maps;

var one = { '1': { id: 1, pid: 1, name: 'John'},
        '3': { id: 35, pid: 3, name: 'Josh'},
        '5': { id: 34, pid: 5, name: 'Joe'} }

var two = {1:1, 34:1, 35:1}

Object.keys(one).forEach(function(item){
    two[one[item].id]= {pid : one[item]};
});

I want result as

{1:  { '1': { id: 1, pid: 1, name: 'John'}, 34: {'3': { id: 34, pid: 3, name: 'Josh'}}, 35:{'5': { id: 35, pid: 5, name: 'Joe'}}}

But I'm getting

 {1:  { pid: { id: 1, pid: 1, name: 'John'}, 34: {pid: { id: 34, pid: 3, name: 'Josh'}}, pid:{'5': { id: 35, pid: 5, name: 'Joe'}}}

But i'm not getting dynamic pid , only stack pids. I know above loop sets it in static id, want to solve it to get dynamic pid.

If you format the object literals in your question and make them readable, you will see they are malformed. — Oriol, Jul 04 '14 at 02:22
Sorry I just want to make sure, I think you have misplaced 2nd and 3rd object in your expected result. — Mritunjay, Jul 04 '14 at 02:26

To get the good result, just set the "pid" as a key like you did for the "id":

var one = { '1': { id: 1, pid: 1, name: 'John'},
        '3': { id: 35, pid: 3, name: 'Josh'},
        '5': { id: 34, pid: 5, name: 'Joe'} }

var two = {}

Object.keys(one).forEach(function(item){
    var current = one[item]
    // We initialize empty object
    two[current.id]= {}
     // We set the object at key .pid to what is wanted
    two[current.id][current.pid] = current
})

console.log(two)

Result (in JSON):

{"1":{"1":{"id":1,"pid":1,"name":"John"}},"34":{"5":{"id":34,"pid":5,"name":"Joe"}},"35":{"3":{"id":35,"pid":3,"name":"Josh"}}}

works as expected but I'm getting the whole things twice, just as expected but twice. – user3803784 Jul 04 '14 at 02:27
What do you mean twice? I'm getting it only once on my side (tested the code on chrome console directly) ! Might be a double console.log? – Hugo Dozois Jul 04 '14 at 02:28

What you said you want isn't a valid object. My guess is that you want

var one = {
    1: { id: 1, pid: 1, name: 'John'},
    3: { id: 35, pid: 3, name: 'Josh'},
    5: { id: 34, pid: 5, name: 'Joe'}
}, two = {};
Object.keys(one).forEach(function(item){
    two[one[item].id]= one[item];
});

var one = { 
    '1': { id: 1, pid: 1, name: 'John'},
    '3': { id: 35, pid: 3, name: 'Josh'},
    '5': { id: 34, pid: 5, name: 'Joe'} 
}

var two = {1:1, 34:1, 35:1}

Object.keys(one).forEach(function(item){
    var obj = {};
    obj[one[item].pid] = one[item];
    two[one[item].id]= obj;
});

console.log (two);

This should work for you.

var one = { '1': { id: 1, pid: 1, name: 'John'},
    '3': { id: 35, pid: 3, name: 'Josh'},
    '5': { id: 34, pid: 5, name: 'Joe'} };

var two = {1:1, 34:1, 35:1};

for (key in one){
   var item = one[key];
   two[item.id] = {};
   two[item.id][item.pid] = item;
}
