An HTML document without a title element is invalid. Christopher has
given you a jQuery answer, a generic answer is that if you try to get
a property of an object that doesn't exist your script will error. If
you want a belt braces approach, try something like:
var o;
if ( document
document.getElementsByTagName
(o = document.getElementsByTagName('title')[0])
(typeof o.text == 'string') )

[jQuery] Re: How is height calculated?
Klaus, Humm, I still can't get the size of an element while it's hidden and absolute... I tried with an element: style=display: none; position: absolute and alert(id: + elt.id + height: + elt.offsetHeight + width: + elt.offsetWidth); alert(id: + elt.id + style.height: + elt.style.height + style.width: + elt.style.width); I still get height:0 and width:0 and style.height as well as style.width. Did you mean that the element position is made absolute, moved off screen and made visible to get its size and then made static and hidden again? Thanks Fred On 6/17/07, Klaus Hartl [EMAIL PROTECTED] wrote: Fred Janon wrote: Hi, I am trying to understand how the height of an element is calculated in jQuery. I don't understand how the height can be calculated especially when the element is hidden with display:none. Thanks Fred Fred, if the particular element is hidden, it is absolutely positioned while invisible (and the parent element its context), instead of display: none, and the height can then be calculated. Thereafter these styles are resetted. There is one issue: If not the element itself but some parent element is hidden via setting display to none, you won't get the correct height. Its just to expensive to use the above described technique for some parent element. --Klaus
[jQuery] Re: Printer Friendly Form Field Replacements
Because its not just the look that matters. If you have a long text value in an input element, then the text value gets cut off. Can you use CSS to fix that?

Hi there, I am adding input elements using jQuery and these input elements shall react on globally registered event handlers ( $(.myelement).click() ).

[jQuery] Re: Refreshing event registration
Arne,
When jQuery 1.1.3 comes out you will be able to use Brandon Aaron's
Behavior Pluigin[1] to manage this behavior automatically. Until then
you can do it manually. They key is to only bind the elements that
have not been previously bound. If, for example, you're using ajax
functionality to replace the contents of a form you can do something
like the following:
function addBehavior(sel, context) {
$(sel, context).click(function(){});
}
$(document).ready(function() {
addBehavior(':input');
// example 1: load method
$('#example1').click(function() {
$('#myForm').load(function() {
addBehavior(':input',this);
});
});
// example 2: simple form plugin usage
$('#example2').submit(function() {
$('#myForm').ajaxSubmit(function() {
addBehavior(':input',this);
});
return false;
});
// example 3: advanced form plugin usage
$('#example2').submit(function() {
$('#myForm').ajaxSubmit({
target: '#myForm',
success: function() {
addBehavior(':input',this);
}
});
return false;
});
});
If you're just adding some elements on the fly they you'll need to be
slightly more clever but as long as you know what you've added you
should be able to either cache them or select them and apply the
desired behavior.
// cache example
var $a = $('input name=a value=x').appendTo('#myForm');
var $b = $('input name=b value=y').appendTo('#myForm');
addBehavior([$a,$b]);
Cheers.

[jQuery] Using Sortables with tables
I have a CMS that I'm building for a client. There's going to be a list of items in one portion of the CMS which will likely get rearranged on a regular basis. Obviously I could simply have them change their order one at a time via a simple text box. I'd like to give them something unexpected though and make their lives much easier. So I'm considering the option of using Sortables to allow them to drag and drop to rearrange. Here's a small sample of my HTML code. At this point, each row would look just like this: tr valign=top class=listmainbg td align=center1/td tda href=modules.cfm?action=contentid=6 title=Edit the settings of this moduleCover Letter/a/td tdText/td td width=20a href=modules.cfm?action=contentid=6img src=images/edit.gif width=16 height=16 border=0 alt=Edit the settings of this module/a/td td width=20a href=modules.cfm?action=submitdeleteid=6img src=images/delete.gif width=16 height=16 border=0 alt=Delete this record/a/td /tr Each row will have a class of listmainbg, and will most likely have a unique ID which correlates to it's current display order (the first TD). What I would like to do is have the user drag and drop a row into the position they would like to be, then trigger a callback which renumbers the entire likst (or maybe just the ones which need to be changed?), then sends that array to an AJAX call to update the database. So the questions: 1) Has anyone else done something like this? 2) Do I need to make any changes to my HTML code? 3) Is this a crazy idea? Thanks for any help you can provide. Word!

[jQuery] AJAX get into a persistent variable?
I'm working on a page that has a form that is dynamically generated
using jQuery. The form isn't built in one pass but progressively
based on user actions. Prior to submit the form may contain dozens of
select menus with varying option content.
The problem is that the select menu options contain values that are
stored in database. Those values can change, therefore it isn't safe
to hard code the menu options in jquery code.
I realize that I could make an AJAX call each time I need to build a
menu, but that will slow down the form generation. It is safe to say
that the values won't change during a user's session though. What I
would like to do is cache the various menu values when the page loads,
but I'm not sure the best way to do this?
Is it possible to perform a $.get() and store the result into a global
variable? I've tried something like this but it doesn't work.
var foo = '';
$.get(options.php, function(data){
foo = data; // try to store data into foo
});
Optionally I suppose I could do something like this ...
$.get(options.php, function(data){
$('body').append(p style=\display:none\
id=\footext\ +
data + /p); // store data in a hidden page element
});
and access get the value via $(#footext).text() everytime I need it,
but would prefer to use a variable.

I've made this smooth image-list slider :
http://dev.byron-adams.com/jquery/slider.html
it was originally using prototype scriptaculous (130kb+)
so it works pretty well, except for one issue that seems to have
somthing to do with the animate function/method
let me attempt to explain how this works,
if you click the right arrow button $(#control-next), the $
('#imageBoxInside') box will slide a set amount of pixels to the left,
in this case it slides to -720px; and if you click the left button
(after clicking the right one) it SHOULD scroll back to 0px, but
instead, its scrolling back past 0px all the way to -2px.
At first I thought this was obviously an error on myhalf, but apon
futher inspection the problem seems to with jquerys animate()...
some googling revealed this has occured before:
http://blog.joshuaeichorn.com/archives/2007/01/11/jquery-image-strip/#comment-192037
and it doesnt seem like the author of that script is even aware of
it...
anyone encountered this before?
any ideas?
any response welcome :)

It doesn't seem to happen consistently...

there's a compounding rounding error or something? Maybe try setting
the correct value after the animation has completed (via a callback)?

[jQuery] getScript problem
I have tried to test on the twitter json and so I use the getScript to do
that.
It works in IE but not Firefox. The js console error shows:
[Exception... ' P ³å|ë method XMLHttpRequest.open' when calling method:
[nsIDOMEventListener::handleEvent] nsresult: 0x8057001e
(NS_ERROR_XPC_JS_THREW_STRING) location: unknown data: no]
I'm using the latest packed version on jquery.com front page, which should
be 1.1.2.
Code:
html
head
titleTest jQuery Twitter/title
script type=text/javascript src=jquery.js/script
script type=text/javascript
$(document).ready(function(){
var url =
http://twitter.com/statuses/user_timeline/jackysee.json?callback=twitterCallbackamp;count=1
;
$.getScript(url);
});
function twitterCallback(obj){
$(#text).html(obj[0].text);
}
/script
/head
bodyp id=text/p/body
/html

[jQuery] Re: getScript problem
jQuery's getScript implementation uses ajax and therefore you can not
make cross-domain requests. But Michael Geary has a nice JSON plugin:

[jQuery] Re: problem with animate()...
Thanks,
I tried setting it in the call bak like so..
...
$(#imageBoxInside).animate({left: sLeft}, 'slow',
function() {
wait = 0;
var left = parseInt($(#imageBoxInside).css(left));
if (left 0 left -(imageSize * transitionSize)) {
$(#imageBoxInside).css(left, 0px);
}
});
...
and that works great :)
But it would be nice to not have to use the hack...
im still not really sure if its my code or jquery thats causing
rounding error...

[jQuery] Re: problem with animate()...
Byron -
You should give jQuery 1.1.3a a try. This was one of the nasty bugs
that we were able to resolve in it:
http://code.jquery.com/jquery-1.1.3a.js
Let me know if that code helps to solve your problem.
