Re: [jQuery] Re: Two search kriteria
Do you have firebug installed? Or Safari? Or something which gives you a
console? If so, before the autocomplete line, insert:
console.log( $('#zip').val() );
By the way, it was 'val' and not 'value', I was working from memory, and my
memory was obviously a tad faulty. I usually don't use it, so...
Where would I look it up? The jquery documentation: api.jquery.com, more
specifically http://api.jquery.com/category/attributes/
Anyway, if the console.log command outputs the correct value, check to make
sure that the back-end script is being called. If not, we will need more
details.

Give your Zip field an ID, then use $('#zip').value() instead of

Re: [jQuery] jQuery and div/iframe/pane content replace
You could probably come up with a dozen ways of doing it. You could have
different divs all loaded but hidden, then hide and show them as needed,
which would be a very different animation than you have now. Or you could
use ajax to load the different DIV contents (which might be nice for site
organization) and then either load them into the hidden divs or just store
them in variables for swapping in and out.
If you need fancy animations, you are going to want to do something like
hide (or fade out) the old div, and then have some custom animation that
causes the new div to appear in the way you want it to appear.
If you are aiming for search engine optimization, you probably don't want to
rely on AJAX to load the content. You probably want to just have three (or
more) divs that start hidden. Each has a unique ID. You could even store a
reference to a unique 'animateShow' function attached to each div.
One
Two
Three
...
One's content
Two's content
Three's content
Assuming each div needs a custom 'show' animation, you could do this:
$('#one').data('animateShow',showOne);
$('#two').data('animateShow',showTwo);
$('#three').data('animateShow',showThree);
Then to hook it all up:
var activeContent = 'one';
$('a.leftMenu').click(function(ev){
var targetId = $(ev.target).attr('target');
if ( targetId != activeContent ) {
var targetDiv = $('#'+targetId)[0];
if ( targetDiv != null ) {
$('#' + activeContent ).fadeOut('fast');
var animation = $(targetDiv).data('animateShow');
if ( animation ) animation( targetDiv )
else $(targetDiv).fadeIn('fast');
activeContent = targetId;
}
}
return false;
});
Hope that gets you down the road towards where you want to be.

Re: [jQuery] Re: New Forums
Silly thought: What if the forums were 'published' to the mailing list, and the mailing list were made read-only? That is, every time a post is published on the forum, it is automatically sent to the mailing list. Then, in the footer of the message is a link to reply to the post, which when clicked takes you to the forum in such a way that the user can immediately reply to that post. The mailing list could be set up so that nobody except the forum 'bot' could post to it, which would make spam go away. People that have accessibility issues or just prefer to get their information via their email client could continue to read things that way. And you would have all of the benefits of the forum. Best of both worlds. Make everybody happy. I know it would make me happier.

Re: [jQuery] Re: saving state of treeview and form data afteer refresh
So if I understand correctly, you are trying to make the page links work in
a search results page?
So let's pretend it is Google. You have a search form at the top, so you
can search again, and you have some search results, and you have a series of
links that represent which page in the search results you want to see.
Assuming that is the set up, there are many ways to do this, but the
simplest way I can think of is this:
You have your initial search form.
Add a hidden form field, call it 'viewPage' and initially set the value to
'1'.
When the user clicks Search, the PHP script gets the message that it is
supposed to display page 1 of the results.
It generates the results page, like you are used to.
In that result page is the search form, again, including the viewPage hidden
field.
The default value of the search form is the value that was passed in to the
script that generated the page. That part is done in PHP, not in
Javascript.
Same with the viewPage hidden value.
Now, the page links invoke JavaScript which modifies the viewPage variable,
and then submits the form.
Then, when a link is clicked, the user sends the search string back to the
server, along with the 'viewPage' parameter.
Your server-side script looks at it, sees that you want page 2, for example,
and generates the appropriate result.
WARNING: If you modify the search term, and then click a page link, it may
not do exactly what the user expected. If you don't want it to behave that
way, you will need to save the original search term, and submit that.
Now, if you are trying to do this all dynamically, and trying to avoid any
page reloads, then modify the page number links so that the click event
returns false. Then, the page will not reload, and you won't lose the form
contents.

Re: [jQuery] saving state of treeview and form data afteer refresh
Try creating an unload event handler that goes through your forms and writes
the data therein to a cookie. Same thing with the state of the tree. Then
write an onload event handler that looks for the cookies, and if found,
populates the form elements and the tree state.
If that doesn't work, then you are going to have to add events to all of the
form elements that allow the cookie data to be saved as you go.
But... why are you pressing F5 in the first place?

Re: [jQuery] Lists, Filtering and Searching, Oh My!
json is one approach. XML is another. CSV works, too. The format of the file should be what works best for the people that need to maintain it. Then, you need to find a good way of getting that data into the browser and in a format that is easy to work with. How often does this file change? Is this something that can be loaded at the beginning of the user session and then cached? Or do you need to update the user's view regularly? That is, do you need multiple ajax calls, or just load it all in on page load? If it were me, using Excel to manage the list, and exporting to CSV, then loading and parsing that is probably what I would do. Just make sure your CSV parsing code is bug-free. :) When you load and parse the CSV, just load each record into an object in an array. Piece of cake. Then you build your display based on the array, sorting and/or filtering as you do so, based on what the user needs. That last part has the potential to be a slightly sticky piece of cake if you tried to do it all yourself, but even then it is doable. Using the QuickSearch might work, but looking at the sample, it's pretty slow with even a small list (looking at the table example), so with such a large data set, it may not be much fun. Won't know until you try. There are also plugins (are there not?) which turn tables into sortable/searchable data sets. You could build one of those as an 'alternative possibility' for your users to look at.

Re: [jQuery] Animation for cloned elements
Is the item you are cloning already visible? If so, there is nothing for
'slideDown' to do. After you clone, but before you append, make it so that
it is not visible (by whatever means is most appropriate), and see if that
solves the problem.

[jQuery] Mixing jsTree with jqueryUI draggable and droppable
I'm trying to create a tight integration between two trees and a 'desktop'
on which are floating elements (cards). I need to be able to:
* drag and drop a tree node to the 'desktop' to 'open' the card that the
node represents
* drop a tree node onto an open card in order to create a relationship
between them
* drop an open card onto a tree node (also creates a relationship)
* drop either an open card or a tree node anywhere on the 'tree' object that
is not otherwise a drop target in order to effectively drop the card on the
'root' node of the tree
(because 1.0 is not out yet, I'm using 0.9.9a of jsTree)
I added droppable to my desktop element, but no event fires when I drop a
tree node onto it. What is the correct way of telling when a tree node is
dropped on something outside the tree? Does the helper need to have the
ui-draggable class in order to work with a droppable, or is there more to
it?
I also added a call to the tree's drop_mode inside the draggable's .start()
event. I can't see any evidence that it did anything, other than I know the
call was made: $.tree.drop_mode({type:X}). Now, when I drag around a card,
it drags the original element, so it is possible that the mouse events are
being received by the card element, and never making it to the tree. But
the drag-and-drop behavior of the card is exactly what I want, the card is
semi-transparent so I can see what I am dropping it on. Items set as drop
points using 'droppable' work fine, but the tree does not. What is the
correct way of working with the tree and 'draggable' objects?
Also, draggable objects support a 'revert' animation. I'd like to be able
to revert the dropped card if I am holding the meta key, and close the open
card if I am not. That is a question for the jQuery UI team, I suppose, but
I'm asking it here, too, in case you happen to know the answer.
Another thing I want is to have the default behavior differ depending on
whether or not I am dragging-and-dropping within a tree, or between trees.
Within a tree, I want the default action to be a 'move'. Between trees, I
want it to be a 'copy'. Looking at the source, it looks like it won't work
that way. Am I understanding what I am reading correctly? Is there a way
to simulate it? Or do I need to add a feature to the tree code in order to
get that behavior?

Re: [jQuery] Re: background-color always returns "transparent"
Make sure you are passing in a document node and not a jQuery object.
if ( elem instanceof jQuery ) elem = elem.get(0);
If you were passing in a jQuery object, the 'parent = parent.parentNode'
line would immediately set parent to null.
Also, shouldn't your getColor function return the color if it is set on
elem, too, instead of always looking up the chain? Doesn't it make more
sense to have one call, rather than putting some of your logic in the
function, and some outside of it?
function getColor( of, what ) {
var elem = of;
if ( elem instanceof jQuery ) elem = elem.get(0);
var color = null;
while ( elem != null ) {
color = $(elem).css(what);
if ( color != '' && color != 'transparent' ||
jQuery.nodeName(elem,'body') ) break;
elem = elem.parentNode;
}
return color;
}

Re: [jQuery] Passing parameters by object
If I were you, I would resist the temptation to do too much 'correctness'
checking if it is a plugin that you are releasing to the general public.
The reason I say that is sometimes it is desirable to add extra things in to
your configuration that the plugin doesn't expect, so that it gets stored in
context. To allow that to happen, don't halt execution if you find
something you didn't expect, just log it.
(function($){
// list all of your expected options and their default values here
var defaults = {};
var validateOptions = function(o) {
for ( var i in o ) {
if ( ! defaults.hasOwnProperty(i) ) console.log( 'MyPlugin:
unexpected option: ' + i );
}
};
var MyPlugin = function(o) {
validateOptions(o);
o = $.extend({},defaults,o);
...
};
})(jQuery);
Also, once you have everything debugged, I would comment out the call to
validateOptions, so that production code is not generating console output,
since that may generate errors for some users, and does not serve anyone but
the developer.

Re: [jQuery] Looping help
Before we start, note this:
http://www.w3schools.com/tags/att_standard_id.asp which says that an ID must
begin with a letter. So you are going to need to modify your HTML so that
your ID values are letter then number. Chances are, this is your whole
problem.
var list = /* JSON array */
for ( var i = 0 ; i < list.length ; i++ ) {
var id = 'img' + ( i + 1 ); // assumes div ID's are 'img1' and 'img2' and
so forth. Adjust accordingly
var img = document.createElement( 'img' );
$(img).attr('src') = list[i];
$('#filmstrip ' + id).append( img );
}
There are many ways to do this, the above code is just a clean, instructive
way of doing it.

Re: [jQuery] Re: background-color always returns "transparent"
As a QA tester with a lot of test automation experience, a bit of advice:
Ask if the product would not ship if it wasn't red. If the answer is no,
then you might not want to waste your time. Unless you have automated
everything else about the functionality of the application, and are looking
for things to automate, but I would be surprised if you had gotten that far
already! :)
There are some other things you can do, too, to make it easier or faster.
If you want to discuss it off-list, email me at j...@irie-inc.com.

The short answer is because the background color of the item you have
selected is in fact transparent.
Your style makes the tag red. Then you query on a child element that
has no color specified. The background color of the child element is
'transparent' which means that the color of something up the tree is what
you will see.
You will never see 'red' by looking at the child element. But what you can
do (and jquery.color.js does this) is while you get 'transparent' then you
can look at the parent object. You can walk up the tree until you get what
you are looking for.
But before you go down that road, why are you looking to see the color of
the element? If you can describe what you are trying to do in more general
terms, someone may be able to give a better suggestion on how to accomplish
it.

Re: [jQuery] Re: Extracting content from a div?
If the html is in a string, e.g. 's':
$(s).html() would return everything inside the outer div.
If it includes more than just that error, you can do something like:
$(s).find('div.error').html()

Re: [jQuery] Custom animations
Try animating the position at the same time. Or, position the element based
on the corner that you want to remain fixed. Exactly how to do it depends
on what other restrictions you have on what you are trying to do. Put
together a sample page.

[jQuery] Re: Anybody ever come up with a good way of doing dynamic CSS?
Sorry, I hit tab/space which auto-sent. Let's try to finish this...
Basic idea is a template:
.card .ct-$(type.id()) {
width: x; /* etc. */
color: $(type.color());
}
In truth, it is a little more complicated, because I have to make lots of
rules for all different classes, but the key element is that they have
different colors (at least), and I want to be able to define them based on
configuration that I loaded via AJAX, which defines the types.
Now, I need to take the existing CSS file, loop through all possible values
of object 'type' and then generate new CSS and make it be included in the
document.
I've seen the 'rules' plugin. I suppose I could fetch my 'template' css
file, do find/replace on it to substitute the appropriate values (once per
type), and then use the Rules plugin to add the rules to the current
document.
But I wonder: Is there a more elegant (client-side) solution? Has anyone
else ever done client-side CSS rule generation based on data returned from
the database? I'm just looking for people's ideas of 'best practices' since
I know that CSS doesn't yet support macros (right?).

Re: [jQuery] ajax form plugin submit button
All of your forms must have an event handler associated with their onSubmit event. These event handlers need to do their AJAX stuff, and then stop the browser from doing the default action by returning false. Since you are creating these forms AFTER the page has already loaded, you need to either create this event handler as part of creating the form, or use $().live() in order to capture the event for ALL forms, present or future. However, I don't know that .live will work for that, I haven't tried, you will have to experiment.

So, why can't you just create a new node with a src attribute? It will automatically download the image in the background, much like with AJAX.

But if this code will get executed more than once (e.g. in response to user

Re: [jQuery] Help needed to find image dimensions
It would be wonderful if I am wrong, but I don't think you can get the image
dimensions via JavaScript. But you don't need to...
a.preview {
max-width: 200px;
max-height: 200px;
}
This will force the image to fit within a 200px by 200px window without
altering the image aspect ratio.

[jQuery] Draggable/Droppable - revert:'invalid' working on Firefox, not on Safari
I am creating objects on the page which are meant to be dragged and
dropped. Here is how I am enabling it:
$(this.element).draggable({
start:P.startDragging,
stop:P.stopDragging,
revert:'valid',
containment:CONTAINER,
snap:SELECTOR,
scroll:true,
stack:{ group: SELECTOR, min: 1 },
helper:'original',
opacity:0.7,
});
$(this.element).droppable({
accept:'.card',
activeClass:false,
addClasses:false,
hoverClass:'dropHere',
tolerance:'pointer',
over:P.draggingCardOver,
out:P.draggingCardOut,
drop:P.droppedCardOn,
});
On Firefox, it behaves as expected. Namely, if I click on a 'card' I can
drag it around to reposition it. If I drag a card over another card, the
events for over/out are firing. When I drop the card somewhere that is not
another card, the draggable::stop event is fired. When I drop on to a card,
the droppable::drop event is fired, instead.
On Safari, all the events APPEAR to be fired normally. However, once I drop
the card on another card, the card I was dragging remains slightly
transparent, and is no longer draggable. It is as though some kind of error
condition happened during the animation of moving the card back to its
original position, and so the animation never completed, and the element is
left in a broken state.
Has anyone else ever seen this? Any ideas what to look at in trying to
debug this?

Re: [jQuery] Problem with jQuery and AJAX
I think the problem here is that you are destroying and then re-creating the
elements. When you destroy the element, you lose all of the event handlers
that you had associated with them.
Try changing to:
jQuery('#login').live('click',function...
And see if that doesn't solve your problem.

Re: [jQuery] Re: $(checkbox).css('background-color',value) does not work on FireFox?
I mean that in Safari and Firefox, the code produces:
Whether there is a visual modification or not, Safari at least tells me that
the background-color is what I set it to be. Firefox tells me it is white.
I was simply wondering whether or not I should waste time trying to figure
out a work-around or not. It sounds like this is just the way it is because
that is how Firefox works. Yes?

[jQuery] $(checkbox).css('background-color',value) does not work on FireFox?
All,
I am building a bunch of widgets, and creating standard tests for each
widget. Part of the test involves setting the background color attribute to
a known value, and then making sure that the widget initialization code did
what it was asked to do.
So, on Safari, the code for the checkbox passes. On Firefox, it does not.
Funny thing, the element has a style for the background color, but
.css('background-color') is not returning the color I set. It is returning
rgb(255,255,255).
Anybody else seen this?

Re: [jQuery] passing variables to JQuery
(function($){
var defaults = {
button: '#buttonId',
form: '#formId',
target: '#targetId',
url:'/change/me',
page: '/change/me/too',
};
clickToLoad = function( options ) {
var o = $.extend({},defaults,options);
$(o.button).live('click',function(){
$.ajax({
type:'post',
url: o.url,
data:$(o.form).serialize(),
cache: false,
success: function(){$(o.target).load(o.page)},
error: function(){alert('data');},
// is this really what you want?
});
return false;
});
})(jQuery);
Here's how you would use it:
clickToLoad({
button: '#theButton',
form:'#theForm',
target: '#theDiv',
url: '/path/to/data/handler',
page:'/page/to/load',
});
It's a little bit better than copy/paste/tweak. Also, by standardizing your
pages so they always use the same button ID or form ID or target ID, you
could put that standard ID in the defaults section. Then, on a page where
it uses the defaults, you can leave those parameters out of the call.
This, of course, pollutes the global namespace. You probably should define
a namespace and put it there. But that is your choice.
Also, re-think your use of .live(). Are you adding and removing buttons
that match that criteria during the life of the page? If not, you don't
need to use .live(). You can, obviously, but should you?

Re: [jQuery] Re: Does jquery have problems with webkit browsers?
I'm pretty sure it has nothing to do with jQuery. I use $.ajax flawlessly
on Safari. However, I did note that some browsers are more forgiving than
others with respect to the data and the data type matching. Make sure you
are telling your ajax call what kind of data it should expect back from the
server, and that may solve your problem.

[jQuery] jquery.color.js no longer maintained?
All, I got bit by a number of bugs in the Color Animations plugin. So, I fixed them and uploaded the fix to the comments on the issue I submitted against it. Then I noticed, other people have submitted patches as far back as almost 2 years ago. So it looks like this module is no longer being actively maintained. If that is the case, how do we go about getting a new release out there? More importantly, when will this functionality be added to the core? :) -- John Arrowwood John (at) Irie (dash) Inc (dot) com John (at) Arrowwood Photography (dot) com John (at) Hanlons Razor (dot) com -- http://arrowwood.blogspot.com Pablo Picasso<http://www.brainyquote.com/quotes/authors/p/pablo_picasso.html> - "Computers are useless.

Re: [jQuery] proper way
Just put the calls to the functions that do the work inside of .ready().
Put everything else outside of it.
As for anonymous functions, they are good for creating a context that avoids
polluting your name space. When the function ends, everything defined
within disappears into oblivion unless there is some reference to it from
the outside. So, you need to create variables or objects outside, if you
want to be able to keep them around. Or, you need to bind the things that
are inside the closure to events on objects (such as the DOM) that are
outside.
