TypeError : transport.responseText has no properties
Hello all,
I''m using prototype in conjunction with Extjs to build out an Ajax-
driven app. I''m noticing that occasionally there will be 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 :
transport.responseText has no properties.

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)

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'')

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)); });

it''s return value, the form is always submitted. ''sup wi

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?

Ajax.Request evalJSON document.write hangs
I''m not the best when it comes to javascript so this is probably a
simple mistake. I''m using the following code to read an external json
file and print out its values. The problem is when I try to write the
value to the browser it causes the browser to load like it hasn''t
finished the javascript code. Its writing the value to the screen so I
think its hanging after that

Capturing draggable revert
I''ve seen a few posts about this, but no answers.
I would like to be able to call a function when a draggable revert
occurs. What I''m trying to do is replace a photo with an icon on drag
(which I''ve accomplished), but I need to swap it back if the revert
fires.
I really, really wish there were an onRevert() option, but there
isn''t, so I guess I''ll
