Use a variable to a variable

Question

I want to pass a variable into a variable

This is what I want

uk.objects.ARG

I have

 var d= ARG

how can I get uk.objects.ARG?

I tried

uk.objects.d

, javascript stores it as the string, not a variable

What should I do in order to make it as a variable ?

Don't confuse *variables* (`d`, `uk`) with *properties* (`objects`, `ARG`) of objects. — user2864740, Apr 04 '14 at 01:06

You can access JavaScript objects' properties also with the bracket notation:

object[property] = value;

The same works for reading. So in your case you could do the following:

var value = uk.objects[d]

(sidenote) `field` AKA `key` (or *property*) Usually we talk about key-value pairs, not *fields*. – Roko C. Buljan Apr 04 '14 at 01:18
(sidenote) *array index notation* is misleading, here we're talking about *properties*, not indexes and specially not *index notation*. Perhaps what you meant to say is `bracket notation`. – Roko C. Buljan Apr 04 '14 at 01:22
@RokoC.Buljan: Thanks, your are right. I edited my answer to be more clear. – tomka Apr 04 '14 at 01:29

I think what you are looking for is perhaps:

var d = "ARG";

uk.objects[d];
