[Proto-Scripty] Class Inheritance Properties

2010-11-29 Thread Luke
Hi there!

Is there a way you can inherit from a class and extend a property from
the parent class with the same property of the subclass? Like if I
have the following 2 classes:

=== ===

var Section = Class.create({

  attach: function(element) {
Object.extend(element, this.extension);
  }

  extension: {
// Methods and properties here
  }
}

=== and ===

var SectionText = Class.create(Section, {

  extension: {
// More methods and properties here
  }

});

=== ===

is somehow possible to extend the extension-property of the parent
class with the extension-property of the subclass rather than
replacing it? Can I maybe somehow access the parent's property from
the subclass to manually extend it?

Thanks,
Luke

You can use the $super parameter name to access the property of the parent
class.

See: http://api.prototypejs.org/language/Class/create/
