adding variables inside nested objects

Question

I need to create a nested object that looks like this

var a = "example"
{Chatting : {a :{ 'id' :a}}}

I can't really find anything online, I tried the code below and its not working

myobj['Chatting'][a] = {
'id': a
 }

• hughes: Your question is quite unclear. What are you trying to do, and how do you know that it's not working?
• pvg: Describe what 'not working' is and what you are actually trying to accomplish. In the example you've listed, it's probably down to your indices not being literals.
• slimboy: Im sorry i have a variable a, and I need to create a nested object using the variable but its just not working

Answer 1

To access the id property of the nested myObj you can try this:

var myObj={Chatting : {a :{ 'id' : 'a'}}};
alert(myObj.Chatting.a.id)

TO create a nested Object:

var Obj = { };
Obj["nestedObj"] = {};
Obj["nestedObj"]["nestedObj1"] = "value";
console.log(Obj);

Answer 2

At once:

var a = "example"
var obj = {Chatting : {a :{ 'id' :a}}};
console.log(obj);

Step by step:

var a = "example"
var obj = {}; // create the object obj
obj.Chatting = {}; // create the sub-object Chatting of obj
obj.Chatting.a = {}; // create the sub-object a of Chatting
obj.Chatting.a.id = a; // set it's id to a
console.log(obj);

Answer 3

Your question is quite unclear. But i guess, you want get element a, right?

let a = {Chatting : {a :{ 'id' : 'a'}}};
console.log(a.Chatting.a);

• slimboy: i edited the question, i need to create the object not access it

Answer 4

attribute names cannot be objects. (string variables are fine)

var a = "example";
var myObj = {
 Chatting: {
 a: { // here it is assumes to be "a"
 "id": a // here exapmle is being stored in to "id"
 }
 }
}
console.log(myObj["Chatting"]["a"])// will let you access it

Answer 5

var a = "example";
var obj = {Chatting : {a :{ 'id' :'a'}}};

Please note that in an object {key:value} key is a string not variable. I am defining here id:'a', which will output

console.log(obj['Chatting']['a']['id']); // 'a'

and adding variable to the object

obj['Chatting']['a'] = {'id':a};

which will output

console.log(obj['Chatting']['a']['id']); // 'example'
