Hi,

Google recently announced their core javascript library - Closure.

MochiKit.DOM.getElementsByTagAndClassName performance

bea...@gmail.com (takashi mizohata) — Tue, 03 Nov 2009 22:23:09 UT

Hi All,
Forgive me, if this is a recurring argument.
Today I was looking at Firebug profiler and I realize that
getElementsByTagAndClassName takes certain percentages of processing
time. And I took a look at the code, and I did a little bit of hand
optimization. It doesn't change any semantics of code, but just

Hi,

I am new to JavaScript and to Mochikit, but I've seen enough of it
(Mochikit) to get very much interested about it. I am currently
looking into the Ajax Tables example from the Mochikit web site, and I
have to confess that I am a little bit confused about the MochiTAL
processing. So, I thought I'd drop a line to check if anyone is kind

Base.js unescape reassignment and intrusion protection systems

mstras...@gmail.com (Michael) — Fri, 17 Jul 2009 01:34:17 UT

I have found a problem with MochiKit Base.js and the intrusion
protection system at work. The IPS truncates Base.js because it
assigns the unescape() function to a variable (in parseQueryString(),
line 1225 in version 1.4.2 of Base.js). The IPS response is documented

Firefox 3.5 and XmlHttpRequest

eoghanomur...@gmail.com (Eoghan) — Wed, 08 Jul 2009 14:59:17 UT

I'm noticing a problem using a deferred with firefox 3.5.

I have a bit of javascript at the bottom of the html to synthesize a
domload event (but I have also reproduced this behaviour with a plain
window.onload event) and fire off an AJAX request :

I'm in the process of putting my site into production state on Apache
2.2.11 with mod_wsgi 2.5 (using TG1.1). The Ajax request works fine
in the development server, but it doesn't for Apache. Keeps looking
to the document root '/var/www/html' for the server-side script '/
login_json' as seen in Apache the error_log.

bind() / memory leak?

kevins...@gmail.com (Kevin Kaiser) — Fri, 19 Jun 2009 15:34:14 UT

I've built a rather complicated web app that makes heavy use of
MochiKit.Base.bind() and partial(). There are no page refreshes in the
app and the majority of the page content between areas of the UI is
dynamically created / removed via DOM methods. A user might spend
considerable time inside the app and it leaks memory like I've never

Widgets in mochikit-patches

Hi,
I've been desperately needing some standard widgets on top of mochikit, and
I found the widgets under mochikit-patches just recently. I'm wondering what
their current status is, if many people use them, and what most people do
for widgets (e.g. using jQuery over mochikit).

Hi there, how about adding a mapi function to Mochikit.Iter which

altenate rows on a table.

[mochikit] MochiKit.DragAndDrop - revert

Hi all,
i have problems using the MochiKit.DragAndDrop interface.
I would like to drag and drop an element on a certain area.
When the element is droped outside this area it should revert

When i set

as on option to the draggable, jumping back to the origin works.

Signal & a proposed disconnect signature

eoghanomur...@gmail.com (Eoghan) — Tue, 05 May 2009 12:43:26 UT

I've previously been surprised by the function signature of
Signal.disconnect ; that it takes an ident, i.e. the return value from
Signal.connect. Usually you'd have to store the ident somewhere and
retrieve it later when you want to disconnect; this isn't always
convenient.

Is the Signal api is missing a version of disconnect which takes the

MochiKit + Google Gadgets + IE6/7?

mhey...@fairoakslabs.com (MXH) — Tue, 28 Apr 2009 23:32:25 UT

I'm having trouble using MochiKit with a Gadget I'm writing for the

I can't get a null result from the fromString method. No matter what
I put in, it's never null. Generally, what I'm expecting it to do is
if I pass in a value that's not hex, not hsl, not rgb, that it should
drop through to the namedColor check and when it doesn't find the
named color, it should return null. But this just never seems to

zin...@gmail.com (Freek Zindel) — Sun, 29 Mar 2009 13:26:54 UT

When looking at the source code for MochiKit I found that the object
hierarchy is created with calls to update. e.g.:

I am eager to learn about the rationale for doing this so that I may
enhance my understanding of javascript.

What is the advantage of using this technique over an assignment such

it to be the most well design library, however I come up with some
objections. MochiKit.Color depends on MochiKit.Style! I will be using

Novice question about debugging deferreds

I'm a pretty novice Javascript programmer, using MochiKit for an AJAX-
based client. I have been having a lot of trouble debugging (I use
Firebug) and I think I am starting to understand why. As far as I can
tell, there's a try...catch wrapped around the firing of my Deferred
callbacks. Unfortunately, this means that when I get something like a

is it possible to determine the source of an iframe when it changes?

rco...@gmail.com (rcoe67) — Wed, 11 Feb 2009 16:32:46 UT

I have experimented with various methods of determining the href for
an iframe when it loads new content but to no avail. I can connect an
event listener that fires when the source changes but the source is
loaded from a different domain and security restrictions make it
impossible to use standard DOM methods to get at the contentDocument.

How can I access the "default logger"? And actually how are

long time.
Any protests? Otherwise I'll just go ahead and clean it up in 1.5.
