Set value to object in property

Question

In JavaScript object, we can

var myobj = {
    x: 0,
    y: {
        n: 6
    }
};
myobj['x'] = 6; // myobj.x will be 6

Can I do something like this with a function?—

myobj['y.n'] = 6;

I don't want use myobj.y.n.

@ThiefMaster But he's still referring to it statically, so it can't be *that* dynamic. — h2ooooooo, Feb 16 '13 at 15:28
I don't know the name of variable, it will be added by the user — Wael Boutglay, Feb 16 '13 at 15:30
But even so, the principle remains precisely the same, it just requires adding some string functions to *find* and `split()` the string from which the values/names are coming. — David Thomas, Feb 16 '13 at 15:31
@Quentin, The objectif is not recieve or return the value, the objectif is set a value — Wael Boutglay, Feb 16 '13 at 15:35
@WaelAmineBoutglay — The principle is the same. You need to access the property in either case. — Quentin, Feb 16 '13 at 15:36

No, there is no built-in way to resolve this kind of object path. However, there are quite a few small libraries available for this such as goodwin.

Or you could implement it on your own. It's not really hard. Simply split the path string at . and then walk through the objects.
