[jQuery] Javascript: OOP help, accessing parent objects

[Gordon]

I am tryign to make more use of OOP techniques in JavaScript, but most
of the OOP I have done up to now has been in class-based languages,
and I'm struggling a little with the prototype based approach used in
javascript.  I know this isn't a jQuery specific question but you guys
seem like the people to ask on these things. :)

The problem is like this.  Suppose I have one object that uses another
object as a variable inside it, like so:

function Contained ()
{
    var self=this;
    self.var1=1;
    self.var2=2;
    self.method1=function ()
    {
    };
}

function Container ()
{
    var self=this;
    self.varA = 'a';
    self.varB = 'b';
    self.containedObj = new Contained;
}

var foo = new Container;

Now suppose I want to access variables of Container from within
Contained, for example I might want method1 to return the value of
varA in Container.  How would I go about doing this?
