Rails spinoffs - Aug 2005 - questions about extend

I''m working with prototype.js to make some widgets, and trying to
figure out working with extend.

I''d like to be able to to extend a class and then call a function from
the super class.

var SuperClass = Class.create();
SuperClass.prototype = {
   initialize: function(somevar){
      this.somevar = somevar;
   }
}

var SubClass = Class.create();
SubClass.prototype = (new SuperClass()).extend({
   initialize: function(somevar, anothervar){
      super.initialize(somevar);  //extend super class'' function here
      this.anothervar = anothervar;
   }
});
