Oh boy... what happened to the principle of least surprise? :) I can invoke the superclass constructor by adding this line:
Animal.prototype.initialize.apply(arguments); But, shouldn't have to do this or use $super(name). The superclass constructor should be called automatically (as in Dojo for example). See the complete code below: var Animal = Class.create({ initialize: function(name) { alert('Animal: initialize'); this.name = name; }, }); // subclass that augments a method var Cat = Class.create(Animal, { initialize: function(name) { Animal.prototype.initialize.apply(arguments); alert('Cat : initialize'); }, }); var cat = new Cat('test'); --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Prototype: Core" group.
