Okay, so jQuery 1.3.2 defines the visible filter like this:
Sizzle.selectors.filters.visible = function(elem){
return elem.offsetWidth 0 || elem.offsetHeight 0;
};
Now I've got a table of hidden (style=display: none) rows. The user
will click something that will .show() a specific row, and the whole
table -- along with a lot of other stuff -- will be displayed in a
lovely thickbox.
The problem is that MSIE 8 assigns offsetWidths and offsetHeights to
the rows; even those with display: none active on them. In
compatibility mode, MSIE will set the offsetHeight to 0, but there
will still be an offsetWidth.
Firefox doesn't have this problem; Chrome doesn't have this problem.
I'm not sure if MSIE got wildly confused by moving hidden rows into a
thickbox. I know I've broken MSIE's rendering of other similar tables
on the page, but I doubt those have anything to do with jQuery.
I've gotten around it by using .addClass and .removeClass and
filtering on that new class instead of :visible, but I'd rather know
that :visible is working as intended in the long run.

[jQuery] Re: question re: .live() and .empty()
The .live() method binds event handlers at a higher level than the node(s) selected. So, in other words the events aren't actually bound to specific nodes so they won't be removed when you call empty. If you need to remove a live event, just call .die(). It is like .unbind() but for .live() events. http://docs.jquery.com/Events/die#typefn -- Brandon Aaron On Fri, May 29, 2009 at 10:06 PM, Jack Killpatrick j...@ihwy.com wrote: I'm guessing that once a .live() instantiation occurs it's there for good.

[jQuery] Re: Questions about $.live, Live Query and performance
LiveQuery when used for events does not use event delegation. It binds the
event directly to the matched elements. The reason the latest version of
LiveQuery depends on 1.3.x is to take advantage of some internal changes to
jQuery, not because it uses live. The live method in jQuery uses event
delegation.
If you use LiveQuery *a lot* then you will most likely see slow downs. Live
Query tries to be non-invasive about its operations but if it is a large dom
with lots of queries, then it will be slow. You can minimize these affects
by using a context and good selectors.
The reason to use LiveQuery over live is if you need to do something more
than bind an event or if event delegation just doesn't work for the event
you are binding. Otherwise you should use live if you need to bind events to
a large number of dom elements that may or may not be in existence at
runtime. If it is a small number of elements and they exist at runtime then
you should still use bind.

$.live and Live Query are both wonderful. I am hoping to put them to

I have a few questions about $.live and Live Query and their effect on
performance.
Background: If I recall correctly, the original release of Live Query
could have some performance problems. I don't remember if things
bogged down when the DOM had a lot of elements, when you added a large
number of Live Query events, did a lot of updating or exactly what.
Question 1:
What were the specific concerns around performance with the 1.0.x
releases of Live Query?
Now with jquey 1.3, there is $.live. $.live does not do everything
that Live Query does, but does do some of it.
Question 2:
Does $.live use a different technique for handling events than Live
Query?
Question 2a:
If it is different, are there any performance concerns using $.live
like there used to be with Live Query?
Live Query 1.1.x requires jquery 1.3. I am guessing that the new
version uses $.live internally.
Question 3a:
Is the performance of Live Query better in the 1.1.x version?
Question 3b:
Are there some selectors that have better performance than others? or
to say it another way, do all of the selectors perform the same or,
for example, does
$('input').livequery('click', function() { });
perform better than
$('input').livequery('change', function() { });?
Using $.live or Live Query.
Question 4:
Is there any difference in performce between using
$('input').livequery('click', function() { });
vs
$(input).live(click, function(){ });?
I am thinking of really diving in to using $.live and/or Live Query. I
am trying to get a complete understanding of all of the issues that
may arise.

It works by referencing the method with bracket or array notation. You can
reference properties and methods of an object this way. For example:
var obj = { test1: 'test_one', test2: 'test_two' };
alert( obj['test1'] ) // alerts test_one
alert( obj.test1 ) // also alerts test_one
The other code doesn't work because your aren't looking for a property on an
object. To make it work you evaluate the expression and then call the method
like this.
(expr ? 'a' : 'a')();
However, since your function 'a' is global it is a method of the window. You
could use bracket notation to reference the method like this.
window[ (expr ? 'a' : 'a') ]()

out how. There are other events in my code that I register as:
$(.foo).livequery(click, function() { ...

$(.foo).livequery(function() { $(this).draggable({ ...

Besides the helper not being generated, the drop event isn't caught either,
so the whole drag drop is broken.

Hi Brandon,
I've tried changing this code:

seems it is. The second line of code works as expected in ie6 and ie7.
Is there another way of selecting a link with a href that matches the

It is most likely an issue with selecting the a tag by the href attribute.
Sometimes the href attribute gets serialized by IE. Try using the $=
attribute selector (
http://docs.jquery.com/Selectors/attributeEndsWith#attributevalue ) to find
that a tag.
$('#mainMenu ul li ul li a[href$=' + href + ']').triggerHandler('click');

[jQuery] Re: LiveQuery with Tipsy (tooltip) help
Are you using jQuery for the AJAX? Live Query really only works
automagically if you are using jQuery to modify the DOM. If you aren't using
jQuery for the AJAX, there are a few options. Live Query has an API doing
things a little more manual. After you load in the content from the AJAX
call run the following code:
jQuery.livequery.run();
That will invoke Live Query as if you modified the DOM with jQuery.

Hmmm ... you don't expect your CSS queries to throw an error if they don't
match an element do you? It'd be silly if it did. Then you'd need
a separate style sheet for each page instead of making good use of reusing
styles. Same goes for jQuery code. Matching zero or more elements is a
corner stone of being able to progressively enhance your web site/app with
unobtrusive javascript.

[jQuery] Re: LiveQuery won't allow explicit onchange firing?
So this is an interesting use case. Typically you use Live Query to bind
events to elements that don't yet exist in the DOM. Granted it binds to
elements that already exist in the DOM as well. However, there is a
miniscule delay in the actual binding and the trigger is happening before
the event is actually bound. One way you can overcome this is like this:
function change(event) { alert( $(this).is(':checked') ); };
$('input')
.bind('change', change).trigger('change')
.livequery('change', change);
I'd say that this is a bug. I'm not sure when I can find the time to fix it
... but in the mean time you can use the above code to work around it.

My problem is the chained change function call. It looks like
livequery doesn't like when I directly call events from within jQuery,
custom events don't work either:
$(input),livequery(demo.change, function(){

This does work, but doesn't utilize livequery:
$(input).change(function(){

alert(checked!);
} else {
alert(not checked!);
}
}).change();
So, my question is, how do I trigger livequery events within JavaScript?

The document ready function in 1.2.6 was updated to wait on styles. This is

could avoid the flickers. You can find the code here:

You can use it just like you use ready but instead of ready it is domready.
$(document).domready(function() { ... });
I'd also like to make mention that it would be good practice to add a class
to the body to signify that JS is enabled. Then use CSS to handle the
display when JS is enabled.
$(document).domready(funciton() {

[jQuery] Re: Possible jQuery versions conflict
Just use jQuery.noConflict(true) to rename the jQuery namespace to whatever you want. http://docs.jquery.com/Core/jQuery.noConflict#extreme var test = jQuery.noConflict(true); Now you can use test(selector) instead of $(selector) or jQuery(selector) -- Brandon Aaron On Thu, Sep 4, 2008 at 3:09 PM, Marcin [EMAIL PROTECTED] wrote: I am very interested in the answer to this question.

[jQuery] Re: Mouseover /Mouseout div issue
Try using the mouseenter and mouseleave special events.
$(...).bind('mouseenter mouseleave', function(event) {
if ( event.type == 'mouseenter' ) {
// just entered
} else {
// just left
}
});
You can also use the .hover helper method which uses mouseenter and
mouseleave behind the scenes.
$(...).hover(fn1, fn2);

I'm working on something similar in functionality to the lexus

I've got a nav element that shows a large div on mouseover and hides

move over any other element in the div and then the div hides.
How can I keep the div showing no matter where I move the mouse inside

The long-hand way of doing this is something along these lines:

The function I've attached with LiveQuery to the Add new question

search, search.php is loaded, which is a form. They enter the

Oh ... you want to make sure the width of the li adds up to the width of all
the images? The earlier snippet just made sure the li was as wide as the
widest image. You could do something like this to add up all the widths.
var width = 0;
$.each( $('li.hello img').widths(), function(i,w){ width += w; });
$('li.hello').animate({ width: width }, 'slow');
As for the feature suggestion ... I think it is an interesting idea. It
might be a little out of scope for this little extension/plugin but I'll
have to give it some more thought. Most of the things you mentioned are

Wouldn't it be a nice feature to add some built-in manipulations to the
batch? i'm thinking 'sum' to add them all and return the result, 'concat',
'join:,' to join each with a comma in-between, 'average' to get the average
of all integer values, etc. a kind of built-in callbacks if you like for
most common operations.
$('li.hello img').widths('sum');

/li
I needed to resize the LI element according to its children IMG
element
attr width. What i did is loop through the jquery collection looking
for the
width attribute value.
with your plugin it would be just
var newWidth = $('li.hello').attrs('width');
$('li.hello').animate({width: newWidth},slow);
Am i correct?

LiveQuery has two types of queries: event and function. A function

from the dom. The function based LiveQuery is not attached to a
particular event. The docs are here: http://docs.jquery.com/Plugins/livequery

[jQuery] Re: How to bind to a dynamically created object
Ugh ... large tables always needs lots of optimizations. First ...
you'll want to minimize the number of .append()s. Concat all your HTML
into an array and then append. Something like this:
var html = [];
for (var i in data) {
// generate your html like this
html.push('trtdblah/td/tr');
}
// once the loop is done ... make the array into one long string and
append
$('#eintragsliste').append( html.join('') );
Next, you are calling LiveQuery every time you append. That defeats
the purpose of LiveQuery. Call LiveQuery once and it matches all new
elements for you. None-the-less... When dealing with events on large
tables my suggestion is to use event delegation. This is primarily to
keep the number of event handlers to a minimum as having lots can
cause issues of their own. Here is a new plugin that handles event
delegation rather elegantly:
http://dev.jquery.com/browser/trunk/plugins/delegate/jquery.delegate.js
You'd need to use it like this:
$('#eintragsliste')
.delegate('click', '.expanding', collapser_expand_all)
.delegate('click', '.collapsing', collapser_collapse_all);
If you wanted to still use LiveQuery you can use the following:
$('.expanding', '#eintragsliste').livequery('click',
collapser_expand_all);
$('.collapsing', '#eintragsliste').livequery('click',
collapser_collapse_all);
But remember to put whichever method you use (delegate or livequery)
outside the loop and use these methods for their strengths. And
remember ... optimize, optimize and optimize some more when dealing
with large tables.

Using jQuery.each will provide you the isolation you need to make your

jQurey.each( [0,1,2,3,4], function(index, num) {
$(#port+num).click(function() { bigchart(num); });

You should also be able to write it like this:

(function(num) {
$(#port+num).click(function() { bigchart(num) });
})(i);
}
However I'd suggest using one of the other example posted here. :)

Hello all,
I recently started using jQuery in Greasemonkey scripts and am loving

I have two Greasemonkey scripts running on a page. Script A adds an
element to the page and binds a mouseover handler using DOM
addEventListener method. This script is not using jQuery.
Script B wants to trigger the event on that element added by script A
using the jQuery .trigger('mouseover') method. But the event doesn't
fire.
Looking at jQuery code (1.2.1) and with the help of Firebug, I found
that .trigger('...') fires if the event handler was specified using
'on...' attributes to an element. But it doesn't fire if the event
handler was bound via addEventListener. This seems to be true whether
the element was native to the page or was dynamically added later by
Greasemonkey.
Is there any way I can make this work, short of merging the two
scripts (which I'd rather not do), or rewriting the script A to use
jQuery .bind() method to bind the event handler?

(http://jquery.com/plugins/project/gradient). it seems that this plugin
works well for creatign gradients in divs but when i try and apply it to a
td, it seems to work in ie but in firefox, it puts the gradient at the top
of the page rather than in the td.
can anyone think of a possible workaround for this?

[jQuery] Re: Scripts at the bottom of the page
This is pretty much outside the scope of jQuery :/. You should bind
events that have the potential to be triggered before the page is
loaded within $(window).bind('load', fn). This will insure that the
page is ready to accept your events ... otherwise the browser just
isn't ready for you to interact with the page.

If you add the code below into the page somewhere, the memory no

Can something similar to this be added to the jQuery library?
[jQuery] Re: LiveQuery (Discuss Please)
I'd argue that it actually provides you more control over the element
in the sense that you will know when it is initially added or removed
from the DOM.
It is actually pretty smart about how it watches for DOM changes.
Thanks to jQuery's architecture this is all possible with very little
initial overhead. For example if you had the following chain:
$('...').css('...').attr('...').append('...');
Live Query wouldn't run until after the append was done even though
the css and attr methods are also monitored. It also doesn't apply
just to chains. The above could also be broken apart and Live Query
still wouldn't run until after the append was done.
$('...').css('...');
$('...').attr('...');
$('...').append('...');
The performance issues come about when you are selecting _lots_ of
elements with several Live Queries. It has the same performance
concerns as you would with regular jQuery selectors. For example to
increase performance give it a context.
$('div', '#myDynamicArea').livequery('...')
That will obviously run faster than just $('div').livequery('...').
As with all performance concerns ... don't get caught up in pre-
optimizations. After the app is built use profiling and experiment
with selectors to find the areas that are actually slowing you down.
Finally, Live Query will never bind a particular event to an element
more than once. In fact it _only_ binds the event (or calls the
callback) once per a newly matched element.
Live Query's main purpose is to solve a _very_ common problem in AJAX
development ... the need to rebind events to elements added to the DOM
after the initial page load. It does this _very_ well and on most
common uses there will be absolutely no noticeable performance hit.

I 2nd Dan's idea. What has made me wary about dipping into using
LiveQuery is:
1. loss of an element of control, compared to just calling a helper
function at the right time to rebind events
2. concern about overhead, since (as I understand it), it's watching for
DOM changes and hence maybe not rebinding things in as efficient a
manner as I would want. This concern could just come from not knowing
(or having looked at) how it works under the covers, but I'd have to
make time for that, to ease my concerns
3. concern about possibly rebinding things that I don't want rebound, so
I'd have to write code to prevent it, ending up with around as much code
as just rebinding via my helper function

Dan G. Switzer, II wrote:
I think what I'd be more interested is having a method that would allow me
to really easily *manually* re-apply effects/events to a jQuery object.
For example:
$('li')
.cache('some.name', function(){
// use the helper function hover to bind a mouseover and mouseout event
$(this)
.hover(function() {
$(this).addClass('hover');
}, function() {
$(this).removeClass('hover');
});
});
Now you could do:
$('li').applyCache('some.name');
Something like that would definitely save me some coding. (I'd allow a
manual cache key, just so you could re-use the chain on other selectors.)
The benefit is you don't have the overhead of having to constantly monitor
the DOM, but you have an easy way to re-apply a bunch of commands to a
selector.
Right now I just use helper functions--which isn't hard, just not very
jQueryish. :)
Too bad there's no way to programmatically know the jQuery chain. It would
be really sweet to be able to do:
$('li')
.hover(function() {
$(this).addClass('hover');
}, function() {
$(this).removeClass('hover');
})
.cache('some.name');
And have the cache() method be aware of all the methods called in the
current chain.

I'd like to second this opinion. I'm using livequery more and more,

[jQuery] Re: LiveQuery (Discuss Please)
Perhaps you didn't see the example page:
http://brandonaaron.net/jquery/plugins/livequery/test/test.html
Doing those same two examples without Live Query would require you to
write other helper functions to bind those events and to manually
monitor when an element is added or removed. Hardly just two lines of
code. Feel free to add an element to the list via firebug as well to
see how it works.
I personally feel that Live Query should not be put in the core. To
many people seem to think it is a replacement for bind and perhaps
that is my fault for making it a little to easy. Remember that the
power comes at the price of performance. Live Query is best used on a
section of your web site that changes via AJAX calls and you need to
bind events or even just know when the change took place. There will
be absolutely no noticeable performance hit when using it this way. It
is when you start using Live Query in place of your regular bind calls
that you will start to see performance drop.
Live Query should not interfere with any Ajax history manager nor any
hijax methodologies. Live Query is only calling .bind for you.
Also Live Query doesn't make you lazy ... it simply abstracts a more
difficult task into one line. The only reason to suspect you've become
lazy is b/c you are a programmer and I believe we are all a little
lazy at times. :p
Live Query is a very cool plugin but don't use it just b/c it is cool.
BTW ... the adoption rate has been pretty good from my perspective.

it solves this problem:
$(div.klass).draggable();
$(#foo).load(url, function() { $(div.klass).draggable(); });
beautifully, as you now only need to do:
$(div.klass).livequery(function() { $(this).draggable() });
$(#foo).load(url);
Since this is an evangelism discussion, I'd suggest that LiveQuery
page doesn't explain the problem it solves. And your sample takes two
lines of code and reduces it to two lines of code. That's not, in and
of itself, compelling.
A lot of us beginners don't get what itch is getting scratched. The
specific suggestion would be to update the Live Query page with an
introduction as to why the plug-in is useful, with an emphasis on DOM
changes via Ajax calls.
[jQuery] Re: live query
Which version of jQuery are you using? Could you post the code that adds the
element? Better yet could you post an example online?
Also if you are just binding an event, you shouldn't use the function
syntax. Do it like this:
$('a[rel=sec]').livequery('click', function() {
doSomething();
});

[jQuery] Re: live query
Try creating a small, trimmed down test case ... removing other elements
from the page. You should be able to find what is causing the problem then.
The only reason live query would be attaching the event to all a tags is if
your selector a[rel=sec] matches all your a tags. You might want to try
running some code in firebug to see what results you are actually getting
from that selector.
