Thanks for valuable info!
But these aren't really attributes, at least in the HTML sense. They're
what I call custom properties, and a central plank of object-oriented
javascript t'boot. I use them all the time, but had no idea they were called
expandos (horrid name), or - more importantly -
I believe so. As I said an expando attribute is basically any
non-standard attribute that gets added to an element (doesn't matter
how).
As Klaus notes, the memory leakage is only a problem in IE when the
attribute references other DOM elements (directly, or indirectly via
closures).

I'm confused. Are these expandos proprietory Microsoft attributes with a
specific meaning, or can it also apply to a non-standard attribute that I
may invent for a particular purpose (eg all collapsible elements on a page
might have a custom attribute collapsible=true)? If it's the latter, I

Expandos are not proprietary to Microsoft. They are custom attributes. For
instance:
var oDiv = document.getElementById('myDiv');
oDiv.collapsible = true; // safe expando
var oSpan = document.getElementById('mySpan');
oDiv.relatedSpan = oSpan; // potentially dangerous expando
Please correct me if I'm understanding this the wrong way. Strings are safe.
Object references are not.
That's correct. It's safe to store primitives in an expando because
the aren't reference counted for garbage collection. But objects are
trouble. An IE memory leak pattern is as simple as
John, is it possible for the packed version to have a trailing semi-colon at
the end? I get errors for the script I include after jquery if this isn't in
place.
Cheers and thanks for another great release,

* Changed: Events are now internally stored in elem.$events rather
than elem.events (due to a nasty bug relating to DOM 0 expandos).
I'm translating this blog into French, but I can't figure how to translate
this sentence. DOM 0 expandos ?

I've noticed a problem in Safari too, this time with the datePicker
plugin (also written by Kelvin - sorry!).
When clicking the date picker icon, Safari immediately crashes every
time when using the 1.1.2 release.

Not sure if this is bug-related or not, but if I try to open the test page in
the full release of 1.1.2 (test/index.htm) it crashes Safari (2.0.4) every
time. FWIW.

For instance adding an expando attribute called hello:

so any non standard attribute accessed simple as object.hello is an
expando? no matter if you call getAttribute or not??

Hi Everyone -
The release of jQuery 1.1.2 is upon us! This is a another bug fix
release. We've fixed a number of outstanding issues. The fixes have

been updated. I have notified Kelvin of the problem, hope he can fix
