Rails spinoffs - Sep 2006 - Extend easily Slider

Hello,
I have extends scriptaculous slider in my open source project JSControlsTags
(http://jscontrolstags.sourceforge.net),
taglib to manage controls (like AjaxTags, but with JSON notation),
in order to :

   - generate automaticly *HTML Div* for track and handlers slider.
   - synchronize slider with a *textbox* (input HTML). When handler
   slide/change, texbox value is updated with slider value. When textBox is
   updated, slider value is set with textBox value (only if this value is in
   the range and is numeric).
   - fire *AJAX request* on slider *change* event (when slider value has
   changed).

You can see slider demo  at
http://jscontrolstags.sourceforge.net/demo/slider/slider.html.

But for extends it, I had to update slider.js to avoid slider was a class.
Is it possible to have a BaseSlider and Slider in the scriptaculous
distribution, like this :

=> BaseSlider

Control.BaseSlider = function() {};
Control.BaseSlider .prototype = {
  baseInitialize:function(handle, track, options) {
 }
... scriptaculous slider javascript

=> implementation of BaseSlider
Control.Slider = Class.create();
Control.Slider.prototype = Object.extend(new Control.BaseSlider(), {
  initialize: function((handle, track, options) {
      this.baseInitialize(handle, track, options);
  }
});

With this technic, we can easily extends BaseSlider.
So for my use case, I can do :

JSControlsTags.Slider = Class.create();
JSControlsTags.Slider.prototype = Object.extend(new Control.BaseSlider(), {
  initialize: function((handle, track, options) {
      this.baseInitialize(handle, track, options);
  }
... other features
});

Regards Angelo
