ASP.NET AJAX Web Services and Prototype Version 1.5.1.1
I wanted to use a web service published with ASP.NET AJAX from
Prototype Version 1.5.1.1
It''s easier to call an ASP.NET AJAX web service by using an ASP.NET
AJAX page with a proxy class, but I have an application which still
has many Classic ASP pages and using Prototype seemed like a better
idea than hand coding the the interactions, or figuring out how to
include all the right ASP.NET

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 :

Re: Ajax.Request question with JSON return
Do I need something like this:
eval(''('' + this.header(''X-JSON'') + '')'')
(taken from Cody Swann,
http://ajaxian.com/archives/prototype-extension-dynamic-script-pattern-support
).
I''m guessing my problem is simpler, and I''m leaving something small out
related to the header though.
Thanks for any help

Weird data from evalJSON
I am trying to have prototype perform a request and return to me a
javascript object representing the json string returned by the
request. I want to iterate over the contents to print each object in
the json string. The value of transport.reponseText in onSuccess is
what I would expect. But once I try to perform evalJSON() on this
text it gives me a bunch of extra function()s when i try to

[Prototype] onSuccess Event and Ajax.Updater bug in IE
Hi all,
Is there a known bug with Ajax.Updater not working in
IE6? I''m having
trouble with a Autocompleter control that calls a
function that contains
an Ajax.Updater as an AfterUpdateElement callback. It
works fine in
firefox, but I don''t think Ajax.Updater gets called
under IE.

So I was doing some experimenting with prototype and ajax and discovered
something interesting. When I use the first ajax call the response from
the server take 53ms. When I use the second on using the prototype

why, and can it be fixed?

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
