[jQuery] Problems with Jquery 1.3 and Google web optimizer?
Hi, When migrating to JQ 1.3.2, we seem to have found an issue with our Google Web Optimizer (GWO) experiments. there seems to be a race hazard of some kind before GWO redirects to an alternate page version. The error is along the lines of document.body does not exist... when we roll back to JQ 1.2 the error dissapears. Has anyone else experienced these issues? Thanks in advance, Elwood
[jQuery] Re: AJAX - ignore mime type
Thanks for your responses guys.
James - I think I'm trying to do the opposite, my ajax call returns
XML, and I want to treat it like plain HTML - but I'll look at your
link and see if it helps, thanks!
Klaus - the API exists already and is used by other client technology,
I don't have free reign to change it... and I shouldn't have to,
everything works fine when i send XML without the mime type!
I just need to ignore the XML mime type, and everything would be
sorted!!!

Hi,
My ajax requests return xml, with the corresponding mime type.
I'm using $.get, as so:
$.get(
$(this).attr('href'),

$('#requestArea').val(data);
},
'html' //type, correct?

$('#requestArea').val(data) sets a text area to say [object

So it seems my setting the type to html does nothing!
I've played around with this a bit, including using other ajax methods
apart from .get(), with the same results.
Am I missing something here?

[jQuery] Can I use a selector instead of this fn to check for .jpg?
Hi all,
I have a function that determines (a bit hackily!) if an image is a
jpeg.
isJpeg=function(src)
{
mySplit=src.split('.');
extension=mySplit[mySplit.length-1];
isJpg=(extension=='jpg' || extension=='jpeg' ||
extension=='JPG' ||
extension=='JPEG');
return isJpg;
};
I think I might be able to rewrite this as a JQ selector involving the
image's src attributes, something like:
$('img').filter(img[src*!='.jpg'])
But I can't get this to work- and I'm especially unsure how to do the
variations of the extension in an OR clause.
Any tips?
Thanks!
[jQuery] Re: .html() only works on original source?
Thanks for that, never done custom events before.
Unfortunately, the whole idea of saving in the $input.data() doesn't
work - I think this is because It's not technically the same DOM
element, it's a new DOM form element, created from the same markup as
one that had data attachments.
I've attached the info to $(document).data() instead, using the key
formId_inputName.
Thanks for your help!

You could use custom events:
$('#form').bind('hidden',function(){

$(this).children(':input').each(function(){

$('#form').hide().trigger('hidden');
$('#form').show().trigger('visible');
there is also a plug-in that implements listeners for all of jQuery's
methods, so you could do something like:
$('form').bind('hide', function(){ });
$('form').hide();
But I couldn't find it. I think Ariel Fresler was involved with it. In

What you can do is save the values at the time of removal, and then re-
fill it when you put it back. Use the data() function:
// removal, store the values
var oldform = $('#form').children(':input').each(function(){
var t = $(this);

[jQuery] Re: is it possible to get result of this
Well, it all depends how you're intending to save the shirt customisations in the back end! Assuming you're saving some list of images for shirts (along with their positions) in your database, there's no reason this couldn't be done via ajax. I'd advise, however, making this save in a traditional full page load for now - it's not usually that difficult to ajaxify something that's already working, and will make the task at hand a lot clearer and more focussed.

[jQuery] Problems using $.load() on remote contentw ith a large dropdown (select)
Hi all, I have a html page with a massive (200+ options) drop down: select name=data[Something][country_id] id=someID option value=1United Kingdom/option option value=39Afghanistan/option option value=40Aland Islands/option etc etc! By itself, this paeg loads fine. When I try to ajax load it using .load, the select box doesn't render properly in any browser - IE gives an empty select, and dumps the countries beneath it, Chrome has an empty select and no sign of the countries. Firefox displays an empty select with the countries beneath, but the countries are formatted as if they were in a select! My first thought was that it's invalid markup, but I can't find anyhting, and as I said it renders fine if you call the page directly and not via AJAX. Anyone seen anything like this before? Thanks in advance...
[jQuery] Best event for changing the content of a div?

[jQuery] Using JQ to parse strings (IE?)
Hi, I hope someone has some tips/advice on this one! I've noticed my code has an issue in IE. I try to apply JQ to a string, as so: $(htmlString).find(someSelector) //htmlString is basically an entire page, someSelector is an ID But IE never finds the elements, even though FF does. I assume putting strings into $() isn't the best practice? I then tried to inject the htmlString directly into the DOM, so I could definitely parse it with JQ once it was part of the page, but this was even worse: scripts started to reload etc, real bad stuff. Has anyone come across this before? Is there an easy way to do this in IE that I'm missing? Thanks in advance :)
[jQuery] Re: requesting and sending JSON in a ruby on rails app
Well, I don't use RoR or treeview, so my advice is more general...
jQuery(#prop-tree).treeview({
url: tree/self_and_children
});
a) No idea what this actually achieves, but I think the goal is to set
the content type header.
Using Firefox (with Firebug/Developer Extensions) you can check if
the content type header is set correctly.
Also, using firebug, you can look at the result sent back via Ajax,
and paste it into the console to see if it's valid JSON/javascript.
Hope that helps...

Hi - first of all this is a plugin-specific question (about treeview)
- i sent it to the plugin discussion page but it seems pretty dead (no
posts for over a year), so i'm sending it here as well. If anyone
could help me out that would be fantastic.
I've been using treeview and have no problems with it so far.
However, to get better performance i'm now trying to switch to the
asynchronous version:http://jquery.bassistance.de/treeview/demo/async.html
In the example they use php to return some json to the tree, but i'm
using it in a ruby on rails app, and can;t work out how to get it to
work. Can anyone help? I'm really just not sure how to get the
required json for the update back to the treeview.
This is what i'm doing at the moment:
In the view:
jQuery(document).ready(function(){
jQuery(#prop-tree).treeview({
url: tree/self_and_children
});
});
...
ul id=prop-tree
/ul
The url tree/self_and_children does seem to be calling the correct
controller and action, which is as follows:
def self_and_children
# expects the id of the branch which is clicked on, which will be
something like
# property_id_79. We want property with id 79.
if params[:id]
property = Property.find(params[:id].split(_).last)
else
property = Property.root
end
@json = property.self_and_children_to_json
respond_to do |format|
if @json
#should never get an html request for this
format.html { render :text = @json }
format.xml { head :ok }
format.js { render :text = @json }
else
format.html { }
format.xml { render :xml = @json.errors, :status
= :unprocessable_entity }
format.js
end
end
end
But, nothing comes back - at least, the tree doesn't change. My
questions are as follows:
a) is doing render :text = @json the proper way to send back the
chunk of json to treeview? Should i do something in a js.rjs file
instead?
b) how do i send through the id of the clicked-on branch to the
controller? (and retrieve it in the controller)
thanks in advance

[jQuery] Re: Simple Ajax calls to server for data
If your AJAX call returns JSON, you might be better off using the JSON
specific ajax methods.
If you're new to JQ and JS, do you use Firebug in Firefox? With that
tool, you can more easily check what's being returned from your ajax
call etc.

going to have an image as a parent? I would assume you're looking for
something more like parent().parent('.display').find('img'), or

If I were you I'd break it into smaller chunks and use Firebug to see

Well, you'll have to make all your forms work traditionally, and use JQ to override them, using things like the ajax form plugin etc. Similiarly, any UI widgets you use should build themselves from existing markup on the page.

In short, you have to:
- make a URL that runs the php script- this should work via your
browser (helloscript.php?user=bob, perhaps),
- call this URL via ajax, and insert the output into the current
page.

Hello !
I have a php function : helloUser in the file : myFunctions.php.
This is my function :

I'm using jquery for an application but i don't know how to call a php
function and give parameter (here :$user) and recover the result (here :
welcome ...).
Can somebody help me?
Thanks a lot.

[jQuery] Re: Using jQuery without ready()
To my knowledge, the main motivation for using ready and similar is that otherwise, you have to pay close attention to where your scripts are included in your page to ensure everything that the script relies on has already been added to that page. For example, if your script affects all .someClass elements, but not all of them have been added to the document before your script file was included, then the ones that came after the script block/include will be missed out.

[jQuery] Overriding form submissions in a way that deals with this.form.submit()
Hi everyone,
I'm using Jquery to override form submits, i.e:
var tabsForms=$('#'+el.id+' form');
tabsForms.submit(function(){...
Pressing submit works fine with this approach, but there's existing
code in the form inputs, such as onclick=this.form.submit.
When the form is submitted this way, it seems that the submit() event
I created via JQuery is ignored, and the form submits normally.
I can't change the zillion examples of this in my existing pages - so
how can I make this.form.submit() submit just like pressing the submit
button now does?
Thanks in advance!
[jQuery] Re: Is this the best way?
Assuming that the level starts at 0,
I think you could apply successive not filters to the Jquery
selection, the first eliminating level=0, the second eliminiating
level=1, etc...

jQuery does not have a built-in selector to compare the values of
attributes, but it allows you to write custom filters (analogous to
plugins). I once found documentation on this but can't anymore. You
sort of have to read the source to learn to do this.
You just extend the $.expr[':'] object with your new filter set to a
string that is evaluated, where 'a' is the element being tested and
'm[3]' is the argument to the filter:
$.expr[':'].levelGreaterThan = '$.attr(a,level)m[3]' ;
Now you can use this anywhere:
$('qualif:levelGreaterThan(3)').remove();
Far more bizarre but potentially useful would be a custom filter that
tests any attribute:
$.expr[':'].attr = 'eval(m[3].replace(/^(\\w+)/,$.attr(a,\\$1\
\)))';
and now write:
$('.qualif:attr(level3)').remove();
Unfortunately the parser for [attr] is not extensible, so you
can't create a [level3] selector directly

Hi Cabbite
Thanks for your 0.02
Its possible to simple use like this?
$('.qualif[level3]').remove();
if level bigger then 3, remove it :)
My code is dynamic, I cant just wrote all numbers I dont need to remove,
like your example. Has to use a condition.

Hi Felix,
I would have thought doing an attribute selector like you suggest was
better.
something like
... $('.qualif[level]).each ...
to at least get rid of anything that doesn't have the level
attribute. Also if you use the same tag name for all of these
attributes its worth adding that as it also helps with efficiency,
i.e. jquery only has to check those tags for level attribute.
Depending on the exact use of the level attribute you might be able
to get just the ones you want by using [attribute!=value] selectors.
i.e. if you want greater than 4 and start at 0
$('.qualif[level!=0], .qualif[level!=1], .qualif[level! =2],
.qualif[level!=3], qualif[level!=4]').remove();
Hope that helps. Also if any more expert on jquery knows more am keen
to know better also.
Cheers, Pete

Hi, I was just wondering if there is any better way to accomplish
that. Some divs has 'level' attribute, with a number. If that
number is bigger than X, will remove the div. var x=4; //
simulating level=parseFloat($this.attr('level'));
$('.qualif').each(function() { if ($(this).attr('level')x)
$(this).remove(); }); I don't know if we can set a filter in $('')
to look at a custom attribute, should be simpler than Feijó
[jQuery] Re: Accessing jQuery functions from outside
Have you tried putting the fn outside of document ready, and then
calling it in both document ready and the onclick?
Btw, you don't put the javascript: in an onclick, only in a href,
that might cause problems too...

I've some functions which I'd like to use outside of jQeury in normal

}
});
/script
...
img src=images/plus01.png onclick=javascript: collapse (17)
div id=#expanded_17.../div
What do I have to write at the onclick?
