Hello everyone,
as you may already noticed from the subject of this post I''m new to
javascript and to be honest if I can choose I''ll certainly
don''t do it
but once javascript is the only way to make web browsers to behave,
well one had to get dirty on it.
Said that, I found Prototype (and Scriptaculous) very nice
frameworks. They have a lot of sense and add a lot of value to the web
developing experience. So I glad you have made this and I can
participate in this group.
For an application I''m doing with Seaside (which uses dinamically
Scriptaculous) I need some events that should trigger scripts
evaluations to be managed in javascript. In the .js libraries I''m
developing to help the rest (almost all UI related) of the application
I want a javascript object that allow me to add the hooks and their
respective actionsScripts to be evaluated that my the Seaside
application setup dinamically so I need a collection (#add #remove and
such) to make it flexible enough but I did''t find Collection in
Prototype. Paradoxically I''ve found a pretty complete iterator (the
Enumerable).
I''ve see with Firebug that making
initialize(){
mouseOutListeners = new Collection;
}
gives me an error because Collection is not defined.
I''ll really appreciate any pointer on this,
thanks
Sebastian

You need to write that as... mouseOutListeners = new Collection(); I believe. Add the ().

Well seems to be that is not enough. Don''t matters I put a) var listeners = new Collection; b) var listeners = new Collection(); c) listeners = new Collection; d) listeners = new Collection(); in the initialize function Firebug is telling me that Collection is not defined. Collection is a standard class in javascript right? or one should include something or what? thanks, Sebastian On 26 maio, 22:28, "Andrew Kaspick" <akasp...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> You need to write that as... > > mouseOutListeners = new Collection(); > > I believe.

There is no built-in Collection object in ECMA script, though the DOM does have an HTMLCollection based on a NodeList - but I don''t think that''s what you''re after. The word "Collection" doesn''t appear anywhere in Prototype.js or Scriptaculous.js.

Oh regardeless of it''s name that''s a Dictionary, a set of keys and it''s values.

Ah! thanks Giuan, I though JS arrays can''t grow. In fact a Dictionary is more what I was looking for and Hash seems to have the intention to be a Dictionary (at least in structure) but I''ve saw that it has a lack of #select, #detect, etc methods so I''m reconsidering using a Hash and try the Array as you said. In a quick view of Prototype code I saw that Hash don''t even seems to be a class so I''m a little confused about that. Anyway.. I will try with anArray because Enumerator provides it of a pretty decent behavior. thanks a lot, Sebastian On May 27, 6:48 pm, giuan <giua...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> On May 27, 2:48 am, Sebastian Sastre <ssas...-luH6fFXSdSWH0oMTQjrRWA@public.gmane.org> wrote: > > > Hello everyone, > > > as you may already noticed from the subject of this post I''m new to > > javascript and to be honest if I can choose I''ll certainly don''t do it > > but once javascript is the only way to make web browsers to behave, > > well one had to get dirty on it. > > > Said that, I found Prototype (and Scriptaculous) very nice > > frameworks.

Sébastien, Good to know. I''ve already implemented with arrays and it seems to be enough by now, but thanks for the clarification because I''ll probably need dictionaries in the future. Questions: 1. how add/remove behave in a Hash object? I mean, one should send to add/remove pairs in it right? 2. I''m about to execute the code I''m developing now for first time and I expecting that Hash stores any object in the value but I also wanted to know if Hash keys can be any object or they should be strings and numbers only?
