[jQuery] What can we use in place of $.browser?
Having just upgraded to 1.3.2, I've realised that the $.browser utility has been deprecated. Does this mean it is no longer possible to identify which browser is being used?
[jQuery] How to animate opacity on Internet Explorer
Using animate({opacity:}) jQuery provides an excellent way of fading
elements in and out of view. However, opacity does not work on IE
(which demands the use of silly filters). With that in mind, how do we
animate the opacity of an element in IE?
Thanks
[jQuery] Re: How can executable jquery/jscript be returned in an Ajax response
Ricardo,
What you are suggesting is what we're already doing. But I would like
to feed that command through the response.
Is that possible?

[jQuery] How can executable jquery/jscript be returned in an Ajax response
Let's say filling a form should add a row to a table. Responding with the html row is not a problem, but how do you include the event to add the row and any listeners which might follow after it? Thanks
[jQuery] Event listener optimisation advice
Hi All, Is there some kind of performance cost in setting up lots of event listeners? For example, rather than setting up lots of click event listeners, would it be better to set up a single one which then uses if/else to decide how to process it? Obviously, it might not always be practical, but I'm just after the theory side of things right now. Thanks. F.

[jQuery] Animating table rows produce *very* strange results. Any work around?
Hi all, I'm having serious problems trying to animate a table row and have tried loads of work arounds In short, I'm trying to do a self healing transation following the deletion of table content using an Ajax call. So, after the user presses delete, the row shrinks in height and is then removed from the dom. Unfortunately, though, trying to do that produces some incredibily strange results. I've put together a bare bones example on http://favouritethings.com/Scrap/RowTest.html Anyone have any idea why this is happening and what we can do to achieve the desired objective? THanks

[jQuery] Does jquery's ajax method's identify requests as being ajaxed
What I mean to say is, do the native jquery ajax methods append any parameters that can inform our server side scripts that the request was submitted using ajax? (e.g. ajax=1) If not, what could be done to implement this so that we don't need to repeat ourselves on each and every form? Thanks
[jQuery] Difficult to describe issue relating to selects!!!
We nest our form inputs into unordered lists and use jquery to
highlight the parent list item of the active input:
$(function()
{
$("ul.form").find("input,select,textarea,option,.file")
.focus
(
function()
{
$(this).parents('li').addClass('ShowGuidelines');
}
)
.blur
(
function()
{
$(this).parents('li').removeClass('ShowGuidelines');
}
);
});
One interesting problem which we're facing is that, when selecting a
select box, rather than bring down the list of options, it simply
focuses on the select box and we then need to click again to bring the
list down (i.e. 2 clicks needed instead of one!)
If the addClass is replace with css(etc.), it works fine.
Anyone have any idea what's going on???
Thanks

[jQuery] Delaying remaining actions until animation is complete
We have a string of actions which run on a click event, but before
they run, we want to animate down the opacity of certain elements to
show the user that something is happening and then animated the
opacity back to normal to show that the process is finished:
$this.animate({opacity: "0.5"});
Action 1
Action 2
Action 3
$this.animate({opacity: "1.5"});
How can we set things so that the actions only begin when the first
animation has finished and how can set the last animation to only run
when the previous actions are finished.?
Thanks
[jQuery] Re: Animate() background colours
Thanks for that. I've got it working now. One question, though, and this applies to all animations... how can the animation be made smoother?

[jQuery] Achieving smoother animate()
We've recently implement an option in which our site's users can hide
and show the left hand menu to make more space for the main content
when necessary (e.g. huge tables).
We've done this through the following code:
$("#ScreenChange").toggle(
function()
{
$("#MenuOuter").animate({width: 0}, 750);
$("#MainOuter").animate({width: "100%"}, 750);
},
function ()
{
$("#MainOuter").animate({width: "75.6%"}, 750);
$("#MenuOuter").animate({width: "22.4%"}, 750);
}
);
The only issue is that, when compared to certain other javascript
libraries, the animation seems to be very joggy.
We are very loyal to jquery (as you'll see when our new site goes
live) and we're very hopeful that there is some way of making the
animation smoother.
Is there?
Thanks
