RE: Yahoo!-like Eventobjectemulation/abstractioninPrototype?
This is obviously rough draft and not thoroughly tested, but it seems to
work. If you''d like, give it a try (load it after you load
prototype.js):
Function.prototype.bindAsEventListener = function(object) {
var __method = this;
return function(event) {
return __method.call(object, new SuperEvent(event || window.event));
}
}
var SuperEvent = Class.create();

Assigning submit handler to form
Hi folks,
A quick question for somebody. I''m adding a simple validation JS to my
form by attaching it like so:
$(''my_form'').observe(''submit'', function(e) { return
view_ns.validate_form(Event.element(e)); });
The validate_form() function returns true or false. But regardless of
it''s return value, the form is always submitted. ''sup wi

Event.observe on IE
I''m working again on unloading events before making my ajax call.
This code works on Firefox/Opera, but IE doesn''t seem to get the
onclick events registered. Could someone with IE take a look?
http://hank.org/demos/ajax3.html
The js is included in that file. There''s alerts() to show when the
events are registered.
The idea of the code is to look for any

getDimensions() fails for elements with ancestors with display: none
Prototype v1.6.0.2
If any of an element''s ancestors are hidden, Element.getDimensions()
returns misleading values. In order to address this in my own project,
I made the following modification:
getDimensions: function(element) {
element = $(element);
var display = element.getStyle(''display'');
+ var hiddenAncestor = element.ancestors().any(function(e)

prototype/script.aculo.us ecosystem
Recently errtheblog (http://errtheblog.com/) put up a nice post about
jQuery. Putting aside all the assertions about cleaner code and fewer
lines of code than with Prototype, the one thing that struck me from
his (and others'') writing and from direct inspection is this: jQuery
seems to have a more of an ecosystem surrounding it. That is, more
plugins, widgets, locked-and-loaded

Styling an Anchor Tag With Prototype
I have a question: How do you style the various components of the
anchor tag? I am doing it this way:
$$(''a:link,a:visited'').each(function(link){ //links
link.setStyle({ color: ''#''+$F(''cp4_Hex'') });
});
$$(''a:hover'').each(function(link){ //links
link.setStyle({ color: ''#''+$F(''cp5_Hex'')

I want something like this to work:

to
var Bar = Class.create(Foo);

Scriptaculous Help (page exit effects)
I was wondering if it was possible in Prototype/Scriptaculous to run
an effect when a link is clicked, then go to that page, or if it was
possible to have an effect run when the page unloads.
I have tried <body onunload="new Effect.Fade("whatever");> and some
prototype page exit events, could get a alert("") function to work,
but not the effects. Any ideas?

I''m using prototype in conjunction with Extjs to build out an Ajax-

Requests that will occasionally not complete. After some
investigation, I found that when I made a call to String#evalJSON, it
would throw a TypeError with the following message :

string.prototype.isNumeric
Hey all,
Just had a need for this, wondering if it is a candidate for inclusion as it
is only a single line and I can''t seem to spot any other way of acheiving
the same functionality in less code.
String.prototype.isNumeric = function() { return (this.match(/^\d+$/) !=
null); }
I used it in the context of:

1.6 cheatsheet
Hey has anyone seen a 1.6 cheatsheet around?
Johnathan Snook did a nice 1.5 one but I''ve been working with 1.6 for a
while and while I can use prototypejs.org, cheatsheets are handy for jogging
memories..
I checked his blog, nothing there for 1.6.

Hi all,
I have multiple textboxes containing numbers. I want to add up all the
