Is it possible to animate the accordion so it opens/closes similar to the accordion in jqueryui?- I have a script that parses an XML doc that was loaded via ajax. On a PC it works fine and takes about a half second to parse. But I also need it to work on a mobile device, where it takes significantly longer (8 - 10 seconds or more)On my ipod touch there seems to be a javascript execution time limit of somewhere around 10 or 15 seconds, and frequently the script is stopped before it completes, so I need to speed it up as much as possible. Can anyone help out with these questions:
- what's the difference between using $.parseXML to loop through a tag in the XML vs just $( xmlString ).find( "tag" ).each() ? I've tried both and it seems insignificant as far as processing time goes
- what's the difference between $( "otherTag", this).attr( "someAttribute" ) vs $(this).find( "otherTag" ).attr( "someAttribute" ) ? I've tried both and these also seem insignificant in terms of speed
A little more background about the XML for anyone interested, the particular spot that's taking a long time is looping through about 270 tags called "prodDetails", each of which has 2 attributes and about 18 child tags with attributes that I need to access. So the code looks something like this:- //xml is a string of xml data
- $(xml).find("prodDetails").each(function(){
- var product = new Array(); // I also tried making this {}; and using "attr" : value below.. no real difference
- product["price"] = String( $(this).attr("price") );
- product["title"] = String( $(this).attr("title") );
- product["categoryCode"] = String( $("category",this).attr("categoryCode") );
- // the following line is repeated about 18 times with slight variations for each attribute
- product["weight"] = String( $("specs",this).attr("weight") );
- });

I've always had a habit of checking if a certain element exists before telling jquery to do anything with it, just to be thorough. But it doesn't generate an error if I just try to attach my miscellaneous code to an element that happens to not exist, so should I bother checking first? Could it actually slow down the code to do lots of these checks, vs just attempting to set up the behavior regardless?For example on product pages I have a particular jquery file that runs, and handles all the behaviors for various products. But not all products have the same features, so I don't always need to set up every behavior, so I check beforehand.- 14-Apr-2011 05:28 PM

I just noticed that some javascript I put in the <head> section of a page that's later loaded via ajax isn't being run in safari. For example here's a page:- <html>
- <head>
- <script type="text/javascript">alert("hi");</script>
- </head>
- <body></body></html>
If I load that page up via ajax:- $(body).load("page.htm")
safari never fires the alert, but all other browsers doIs this by design, maybe head sections are supposed to be ignored in ajax content? It's not a big deal, I can easily put the script into the <body> section which solves the problemJust wondering if it's a bug or by design. Maybe I should stop including <html><head> and <body> tags in ajax content just because of potential problems like this- 23-Mar-2011 05:35 PM

We tested one of our pages on android today and it seems like our email address field always got marked as not being a valid email address, even though it wasI changed the validation to only require an email address if the userAgent wasn't android, which solved the problem enough so that people could continueAnyone know what the problem might be? We were initially using validator 1.7 but I saw that version 1.8 was available so I updated to that, but the problem was still there- I frequently forget my login ID and password, and the login form doesn't allow my browser to remember them (google chrome). As a result I'm constantly going to the forgot password page.Forgetting my password is my own fault, but I think there are a couple of ways to make this easier for people like me1. It wouldn't be so bad if not for that nice checkbox that said 'Keep me signed in' on the login page, which I always check. Apparently the cookie doesn't last that long because I always get logged out anyway. What's the point of this checkbox if it's just going to eventually log me out anyway - I'd rather it was permanent. The text itself 'keep me signed in' seems to imply permanence - for example it doesn't say 'keep me signed in for 2 weeks and then sign me out'2. Alternatively if the login form allowed my browser to save my login info, that would help too

I tried assigning 2 error classes to an error message (as a span), but when the empty field was fixed, the error message wouldn't disappear.- $("#testForm").validate({
errorClass: "ui-state-highlight ui-corner-all",
errorElement: "span"
});
With 1 error class it works fine, but adding a second one makes it fail. Here are some links, just hit the submit button a few times on each one to see what I mean2 classes:1 class:- 04-Mar-2010 11:17 AM

Not sure if this is a bug or by design, but I noticed today that when attempting to get the height of a dialog window that hasn't been created yet, it returns an Object instead of "undefined" as it did in 1.7.2.- $("#dialog").dialog( "option","height" );
This breaks code like:- if ( !$("#dialog").dialog( "option", "height" ) ) {
- $("#dialog").dialog();
- }
Maybe it has something to do with whether #dialog already exists (as a div) on the page- 05-Nov-2009 04:17 PM

Anyone know of a way to get the blind effect, when showing an element,
to roll upwards from the bottom, and when hiding it to roll down from
the top?
I see you can choose between vertical and horizontal but not the
direction of the animation. It's either:
show (vertical) = top to bottom
hide (vertical) = bottom to top
show (horizontal) = left to right
hide (horizontal) = right to left
anyone know if it can be reversed, or if another effect can?

We're loading content via ajax using .load, into a jquery ui dialog
box.
Everything is fine but I'd like to have a loading animation until the
ajax content is ready to go
I tried something along the lines of:
- put a loading animation in "#divForDialog"
- $(divForDialog).dialog().load( 'page.htm')
so the loading animation displays when the dialog pops up, and then
ajax loads content that erases the loading animation
it's fine except that the ajax content still takes a while to load,
but the system erases the loading animation the moment it receives
some of the ajax content
another complication is that the ajax content pulls in images etc via
css and via jquery.css('background-image' : 'url(path/to/file.jpg)')
type calls
I'm sure there must be an easy way to make the .load wait till the
ajax content is 100% done loading before injecting the content?- 17-Jul-2009 07:39 AM

Hi all, I'm trying something along these lines:
my domain = example.com
external domain = otherExample.com
example.com/test.htm contains:
iframe src=otherExample.com/test2.htm
I want test2.htm to have access to the contents of test.htm. I can do
this using selectors like $("p",top.document) ONLY if test2.htm is
loaded from example.com rather than from otherExample.com. As soon as
it's loaded from otherExample.com, it can't get access to the contents
of example.com/test.htm
Is it possible to do this?
thanks in advance- 23-Mar-2009 07:59 AM

I was about to use inArray (http://docs.jquery.com/Utilities/
jQuery.inArray) to determine if an element was in an array or not, but
I realized I can't use it as a true/false response since it returns
the position (and could return 0 if the element was found in position
0 - returns -1 if not found). I was expecting something with the same
functionality as the PHP function in_array (http://us3.php.net/
in_array)
I know it's a minor point but wouldn't it be more intuitive if called
arrayPosition? with a name like that I'd expect the functionality it
has now.
I'm helping someone set up thickbox to work on their yahoo store. It
seems like Yahoo has a built-in click tracking system that is messing
up the thickbox though.
For example clicking on a thickbox link that points to "theFile.htm"
first makes a request to yahoo for something like:
http://a.analytics.yahoo.com/p.pl?a=.......
with a ton of analytical data appended to the URL. It returns a
tracking gif, and the real content of theFile.htm never loads. (you
just stare at thickbox's loadingAnimation.gif forever)
Has anyone ever seen this before and come up with a workaround?- 19-Nov-2008 03:39 PM

Hi all, I have a couple questions about the superfish navigation menu
(http://users.tpg.com.au/j_birch/plugins/superfish/#examples)
First is that the menu claims to degrade nicely when javascript is
turned off -- but for me when I disable JS and hover over the menus,
nothing happens. Even looking at the superfish examples on tpg.com, if
i disable js there the menus don't appear on hover.
Second, anyone know if superfish can be used to display a menu very
similar to REI.com? I can get the nav-bar style to be close, but I
can't get it to automatically extend multiple columns. I'm tinkering
with it but I'm beginning to wonder if I'm better off just creating my
own menu from scratch instead
thanks all
