[jQuery] object parent object

[jQuery] object parent object


My code is working well, but I don't find it very smart, if someone
could give me some leads ...
;(function($) { // create closure
// constructor:
    $.dict = {
        keys : [],
        hash : []
    };
// iterator:
    $.dict.iterator = {
        idx : -1,
        self : $.dict // static pointer on my current constructor not
elegant a nicer way?
    };
...
I would prefer something like this
$.dict = {
    keys : [],
    hash : [],
    iterator : {
        idx : -1,
        self : how to get the parent ?
    }
};
any idea?
