You can certainly set a tr to display:none in IE.

What version of jQuery? What version of IE? Have you looked at your js

Create a page with _only_ jQuery in it, load it in your IE, and see if
it cases an error.

should really have .prop() which would work like attr() usually
intends to, but deal only with DOM properties rather than trying to
manipulate actual attributes. Script authors usually want to deal with
properties anyway, and attr() only makes it confusing.
Matt Kruse
nothing, since you would need funcname1() to actually
run the function.
Or preferrably: setTimeout(funcname1,1000);

There are many examples showing off lots of the functionality here.

if the item to be matched is contained within the
results. This would be slow in some cases, for sure, but would
probably behave as many people expect. It seems like the behavior
of .is() confuses a lot of people when they first use it (myself
included).

might find it useful.

If you've used jQuery on other pages, then it's very likely that the
js has been cached in the user's browser anyway. Loading it again
should not affect load times in most cases.

() is called, it returns the internal height,
minus borders and padding.
When height(val) is called, the height includes borders and padding.
I believe these should behave consistently in quirks mode. In
standards mode they work fine.
For now I will write a fix that switches based on compatMode.

the opposite to be true.
If you change an element's class in IE, the resulting re-flow of the
document can be very slow.
For things like changing styles on hover, I always directly manipulate
the style of the object rather than change the class, since class
changing introduces a noticeable lag in IE.

alternative (=v1.2) could be...
o.filter(function(){return !$(this).parent().is('unwantedclass');});
True, but I'm needing to checking for the class on any element in the
parent chain, not just the immediate parent. So I guess the way I'm
doing it will suffice. Thanks for your help!
Matt Kruse
calling blockUI you can use the same element over and over as shown in the
last example on this page:
Does the example create a memory leak pattern via the circular
reference? I haven't checked it with drip, but it looks to me like a

Fixing browser-specific bugs using browser sniffing is highly suspect
and almost never necessary. In almost all cases, the bug/quirk can be
fixed in the general case without any check for browser.

with wait() - it would eat up the following commands so that a

If anyone thinks this is a good idea and wants to develop this kind of

site that offers this kind of service.
Matt Kruse
that .is() is the correct way to do it. It makes jQuery a
little more approachable and user-friendly if it has exactly what
you're looking for and expect, even though it may just be a wrapper
for the real underlying functionality.
Matt Kruse
to use plugins, the look and feel/API of jQuery
to them will in large part be that of the plugins they choose, which
leaves jQuery's fate up to random developers creating random plugins.
Not so good, IMO.
Matt Kruse
Specificity is a big reason to use id's. You can make a rule using
#id { ... }
and know that it will take precedence over all your tag/class-based
rules.
Matt Kruse
and each'ing or whatever and then calls this underlying method on the
object's className attribute directly.
Is there any reason why it's not done this way? Perhaps there are
things I'm not thinking of :)

it work correctly, but IMO it is worth
it.

One approach would be to put connected rows in separate tbody tags,
then sort the tbody objects based on the first tr in the tbody.
This would be a specialized way of sorting, though, and you would
probably need to write some custom code to accomplish it.

may also be display:none which
would cause it to be hidden as well, and those tags are not parents of
the cell itself. Checking the cell's current 'display' value will of
course get me nowhere.
I've begun writing logic to handle this case, but it would be great if
someone has already done it!
