a = new function() {
this.x=2;
B=function() {
this.y=super.x;
}
this.b=new B();
}
alert(a.b.y); // Expecting 2
In the above, there is a parse error in super. How can I access the value of x when defining the class B?

This works but i'm not sure that your code is correct
a = new function() {
var x=2;
B=function() {
this.y=x;
}
this.b=new B();
}
alert(a.b.y); //alerts 2
alert(a.x) //alert undefined becuase x is private
in any case there is no super in javascript, if you read here you can see how you could implement inehritance in javascript through a uber method

Found the best way to do this is to pass 'this' as the parameter in the constructor of the nested class, like this -
a = new function() {
this.x=2;
B=function(sup) {
this.y=sup.x;
}
this.b=new B(this);
}
alert(a.b.y); // Displays 2
