Question

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?

Answer 1

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
