Rails spinoffs - Jan 2008 - how to extend existing methods functionality in scriptaculous

Hello All,

I''m new to javascript and scriptaculous so I wanted to ask gurus about
CORRECT way of extending already existing methods. Here is my example:

we have:
Autocompleter.updateElement() {

...
if (this.options.afterUpdateElement)
      this.options.afterUpdateElement(this.element, selectedElement);
}

Let''s say I want to "submit form" right after user select new
value in
Autocompleter field. What the CORRECT way to accomplish that? I need
to make something similar to:

function newAfterUpdateElement() {
 .... <do my actions here>...
return this.oldAfterUpdateElement();
}

Autocompleter.prototype.options.oldAfterUpdateElement=Autocompleter.prototype.options.afterUpdateElement;
Autocompleter.prototype.options.afterUpdateElement=newAfterUpdateElement;

thanks,

bigral
