Na. I don't smoke.

Do you mean articles that link to other articles, or chainables in terms of
code, cause I'm not sure the latter is relevent.

Ok.

So how is this relevant to spreading jQuery?

I hope I'm the only one who's confused. :s

[jQuery] jButton released!

2006-09-27 Thread Webunity | Gilles van den Hoven

Hello guys!

I just finished my new plugin and would like to receive some feedback! I 
wrote a new plugin which can transform an image into a button.

Features include:
* Toggle button or a default button
* You can provide a function or string as the action to take when the 
button is clicked. In case of a function, the function gets called. In 
case of a string, the button is wrapped by an href tag and the link is 
called.
* In case of a toggle button, you can preset the state it is in.
* The option to create 2 different styles of buttons. You can either 
create default IMG buttons (which swappes a preloaded image and uses 3 
seperate images) or you can use CSS style swapping, which uses 1 image 
as background, and the backgroundPosition property.

You can check out the demo here:
http://www.webunity.nl/_test/jquery/jButton/

Waiting for your feedback!!

 It was a good concept that wasn't seen in other libraries and makes for 
 short code.
 
 By now Prorotype picked up that concept, Mootools has it and maybe other 
 libraries as well..., so I'm not sure if this is still relevant.

[jQuery] New plugin: Extra :selectors such as :focus, :modified, :input, :text


Simple  http://www.softwareunity.com/sandbox/JQueryMoreSelectors/ selectors
plugin  to add more specific query :selectors to JQuery.

Adds things like:

- $(FORM/*:modified) - To find form elements that have been changed or
selected by the user.

- $(FORM/*:focus) - To find the element that has the focus.

- $(FORM/*:text) - To find texty elements (textarea  input type=text).

And more. Full list and demo at
http://www.softwareunity.com/sandbox/JQueryMoreSelectors/

Note: There have been numerous discussions in the forums about which
selectors are more important in Base and which would be confusing etc. This
plugin aims to separate the bloat for those who want it! Very sensibly, the
Base has been kept uncluttered by keeping out these sort of things.

Cheers all,

George

[jQuery] Tabs plugin: Truly bookmarkable finally

Hi all,

there was one thing that always bothered me (and others on my blog) for 
the tabs plugin: That they weren't truly bookmarkable (only the one to 
start with).

If I remove the return false from the click handler the URL is changed 
   and you get a nice bookmark. Downside is, that the page scrolls to 
the element that is refered to in the hash of the url, or it scrolls to 
the top if you would use a hash that has no counterpart in the document. 
And I didn't want to use undefined hashes anyway for the sake of 
unobtrusiveness and graceful degradation.

So I now save the scrollbars position and set them back to where they 
were on tab click.

Now comes the part I don't quite understand. The technique worked 
perfectly on tabs with an animation, but didn't for tabs that simply 
switched. On these you would see the scrollbar move to the top and then 
back to its old position, resulting in a flicker of the whole page.

Simply enough, I therefore use an animation for any tab switch and it 
was sufficient to make it last one millisecond to avoid the jumping 
scrollbar (so this isn't remarkable at all and behaves like a simple tab 
switch).

Does anyone here know why that is? Anyway, it works and I think it's a 
great improvement.

See here in action:
http://stilbuero.de/jquery/tabs/

I have tested that in Safari and Firefox and Opera so far, in IE I think 
I simply do not get the right value for the scroll coordinates yet. 
Maybe someone can give me a hint...


Cheers, Klaus

I've been playing around with this for some enhancements to the jTip  
plugin and have successfully used this code that I borrowed from  
quirksmode.org and tweaked a bit :

   if (window.innerHeight) {
  scroll_position = window.pageYOffset;
  window_height = window.innerHeight;
   }
   else if (document.documentElement   
document.documentElement.scrollTop) {
scroll_position = document.documentElement.scrollTop;
window_height = document.documentElement.clientHeight;
   }
   else if (document.body) {
  scroll_position = document.body.scrollTop;
  window_height = document.body.clientHeight;
   }

I hope this at least points you in the right direction.

I found out about it sometime in January this year when playing around 
with Feedpile, which was using jQuery as well (by the way - whats going 
on with Feedpile? The site is down for month...).

I then realized too that it was written by the man who won the addEvent 
contest and thought that jQuery therefore must be a good thing.

Until then I used a document.getElementsBySelector function which was 
written - I think - by Simon Willison and so I was immediatly convinced 
by jQuery's advanced selector capabilities.

So when it was time for the Plazes relaunch (March this year) I took the 
chance and decided to use jQuery instead of Prototype or Mochikit, 
because of its size and because of the compact code one could write with it.

That was Revision 29! After all it was maybe a little dangerous because 
it was in a early beta stage to that time. But all things worked out well...

2006-09-27 Thread Rey Bango

I was in the process of trying to choose a route for my Ajax development 
and had narrowed down my choices to what I called The Big Three; 
Prototype/Scriptaculous, Dojo  Mochikit. I read a ton about these libs 
and did the tutorials as anyone would.

Along the way, I kept hearing references to JQuery and decided to check 
it out. So in early September, I signed up for the JQuery mailing list 
and listened in on what was happening in the community. I asked a ton 
of questions  got some great responses. What I found was a great 
community with a solid core group and a great direction. So I took the 
plunge and went through the tutorials and realized how powerful JQuery is.

I have to say that I really like the fact that the core group, 
especially John, is very involved in the community. It truly lends a 
sense of confidence that the project is alive and that JQuery is a 
viable solution to RIA development.

Re: [jQuery] Widget Challenge


Paul,

That's a good start! I see what you're doing!

A larger z-indexed div could be created around each fisheye image, and a
calculation could be done to determine how far from the centre of the box
the mouse cursor is. The image can then be scaled depending on this value.
This also means that the div surrounding the image would intersect with with
the other elements as they would overlap. This should make the animation
smoother.

That's just off the top of my head however.

[jQuery] interesting syntax

2006-09-27 Thread Todd Menier

Hello,I've been poking around a bit in the jQuery source code. It's been enlightening and has proven that I don't know as much about _javascript_ as I thought I did!Here's a pattern that occurs frequently that I'm really curious about:
new function() { // do stuff}Is the purpose of this just to provide local scope to the variables used? Is there an equivalant syntax that may be more common? I intuitively wouldn't even think the code inside the function would get executed unless the whole thing was proceeded by (), but obviously I'd be wrong. What's really surprising is that I couldn't find any information about this technique in a google search.
Just curious.Thanks,Todd

Re: [jQuery] interesting syntax

Todd -

You're correct, it's used to induce a contained scope.

This was a technique that, if I remember correctly, I learned from
Dean Edwards (http://dean.edwards.name/) I use to use:

(function(){
   ...
})();

but new function() { ... }; is much cleaner, IMO. As far as I know,
that is the best way to have a local scope, at least until

Re: [jQuery] Request: Window plugin


Yeah, I got involved with JavaWin a while back but moved on after I found
jQuery. You can still see my name as one of the contributors!

I'm looking to emulate that in jQuery (under the name of jAlerts/jWindows)
for some time.

The basic functionality is already available in thickbox, so it'll probably
be easier to expand that.

I've already done the dragging and minimizing (using Interface), so that's
about 2% done! :)

We had that before. Deans way to create a local scope ((function() {...})()) 
is better, because it doesn't create a new Object that you never use. Of 
course that difference is not too big, but it is there.

Also I don't think that new function() {...} is cleaner or better to read. 
Usually when I read 'new' I expect that a new object is created and I wonder 
what will be done with it.

Re: [jQuery] jButton released!

2006-09-27 Thread Dave Methvin

 I wrote a new plugin which can transform an image into a button.
 You can check out the demo here:
 http://www.webunity.nl/_test/jquery/jButton/

I like the features. It would be better if the markup was a button and the
plugin replaced or changed that as needed. Buttons can have an ACCESSKEY
attribute for accelerator keys (When ACCESSKEY=G, the button is clicked
when you hit Alt-G) and I really like keyboard shortcuts. Using a button
also holds closer to the semantic markup meme that everyone loves nowadays.

This is an interesting design dilemma:

 this.cfgButton = { ... };

Where this is the jQuery object with the images to be converted to
buttons. It's actually one of the documented ways for plugins to have
options, see http://jquery.com/docs/Plugins/Authoring/ . However, if someone
were to try and chain multiple uses of iButton on the jQuery same object,
the later call would clobber cfgButton from an earlier call. Also, one of
the reasons for using an object attached to the jQuery object is to avoid a
closure. In this case the jQuery object is used inside the mouse event
handlers (aliased as _this) so the closure happens anyway. 

Some good messages have gone around about plugin design. I have wanted to
draw those together and expand the Authoring page so we would have a set of
best practices, but I have been too darned busy lately.

I can't recall the exact date, but it was almost a year ago. I stumbled
across a post John had made on someone else's Javascript blog describing the
chained function approach, which led me to his own blog post that had the
beginnings of what was to become jQuery.
http://ejohn.org/blog/selectors-in-javascript/

I was just starting to use Behaviour at the time; all of the frameworks
seemed way too bloated. When I saw the jQuery syntax I was blown away. It
reminded me of Paul Graham's essay Succinctness is Power which does a
better job than I could ever do of putting jQuery's advantage into words.

Re: [jQuery] jQuery Projects

I saw that one one. The mask I am describing is on the phone number field. It fixes formatting on the fly using keypress. (rather than Blur)So it never shows an error, it just fixes the formatting automagically. Try typing in (510) 555-12dog12. It ends up 510-555-1212.
We are going to use something similar for creditcard fields, zip codes, year, or any field like that.The code for it is in the example inlineError.js file at the bottom, but it can be so much shorter using jQuery, I think.

 The current implementation of JTip will cutoff if its too close to the

 Just make your browser small enough so that the JTip would normally be
 cutoff.

 Great job Karl!


Thanks, Rey! If you could see me now, you'd be able to tell that I'm  
blushing.

By the way, if you cut the height of the browser window way down, the  
jTip will first move up and then quickly move down so the top of it  
isn't chopped off. The bottom will still be hidden, but at least it  
gives a visual clue of the size of the jTip so the user can resize  
the browser window if desired.

Unfortunately, I just ran across another weird problem in IE, when I  
got rid of position:absolute for div2. Suddenly the y position  
gets messed up. Works fine in Firefox, though.

Getting there...

Now that  the cat's out of the bag, I'll post an update to the

 curious about: 
 
 new function() {
// do stuff

Yes, that is the one and only reason for it.

 Is there an equivalant syntax that may be

Yes, as others mentioned, ( function() { /*stuff*/ } )(); will do the trick
too, and is slightly more efficient.

 I intuitively wouldn't even think the code inside the

 was proceeded by (), but obviously I'd be wrong.

See if this helps:

   function Stuff() {
  // do stuff
   }

   var stuff1 = new Stuff();  // call the Stuff constructor
   var stuff2 = new Stuff;  // parens are optional

 What's really surprising is that I couldn't find any
 information about this technique in a google search.

It's hard to search for. But it falls out from normal JavaScript syntax and
semantics.

Re: [jQuery] Use $.extend to clone object

2006-09-27 Thread Michael Geary

 From: Klaus Hartl
  
  is it possible to use $.extend to clone an object?
  
  var template = { ... };
  
  clone = $.extend({}, template);
 
 To answer my question, yes it works :-)

Keep in mind that extend() does a shallow copy, not a deep copy.

   var one = { a:1, b:{ c:2 } };
   var two = $.extend( {}, one );
   two.a = 11;
   two.b.c = 33;

Now the objects look like this:

   one = { a:1, b:{ c:33 } }
   two = { a:11, b:{ c:33 } }

The two.b.c = 33; assignment changed both objects, because they share a
copy of the b object.

 While in

 the this keyword points the anonymous object itself, in

The first technique not only creates a new context but also the 'this'-Object. 
try this:

  function test() {
var a;
this.a = 42;
a = 32;
  }

  var b = new test;
  alert(b.a);

This alerts 42. As you see this is another object that the annonymous context. 
The new function(){...}-technique has to create one object more than 
the (function() {...})()-technique.

 You're correct, it's used to induce a contained scope.

 This was a technique that, if I remember correctly, I learned from
 Dean Edwards (http://dean.edwards.name/) I use to use:

 (function(){

 })();

 but new function() { ... }; is much cleaner, IMO. As far as I know,
 that is the best way to have a local scope, at least until
 JavaScript 2.0 comes out and you can do:

 let( foo = 'bar' ) {
// ... do stuff with 'foo'

 // foo doesn't exist out here

Re: [jQuery] interesting syntax

Will, it's the only way (until JS1.7) to declare local variables...
normally JS variables are not allocated in the scope you might guess,
they are allocated at the function level, even if they are deeply
nested.

Re: [jQuery] Use $.extend to clone object



Michael Geary schrieb:
 From: Klaus Hartl
 is it possible to use $.extend to clone an object?

 var template = { ... };

 clone = $.extend({}, template);
 To answer my question, yes it works :-)
 
 Keep in mind that extend() does a shallow copy, not a deep copy.
 
var one = { a:1, b:{ c:2 } };
var two = $.extend( {}, one );
two.a = 11;
two.b.c = 33;
 
 Now the objects look like this:
 
one = { a:1, b:{ c:33 } }
two = { a:11, b:{ c:33 } }
 
 The two.b.c = 33; assignment changed both objects, because they share a
 copy of the b object.

[jQuery] Form plugin's serialize(): performance issues

2006-09-27 Thread Matt Grimm

I've run into a significant performance issue with the form plugin's
serialize method; not a bug per se, but definitely a show-stopper for
me. The problem is that I have a form with a select element, which has
around 250 options. The serialize method grabs *all* child elements of
the form before operating on any of them, like so:

$('*', this).each( ... );

This is awfully inefficient, especially considering each element type is
handled by name anyway in the following code. Perhaps it would be best
to define the top-level or containing elements first, then grab just
those (i.e., excluding OPTIONs):

var elems = ['INPUT', 'SELECT', 'TEXTAREA', ...]
$(elems.join('|'), this).each( ... );

So instead of looking through each OPTION for a selected property, the
parent SELECT could be checked for its selectedIndex property. Any
thoughts?

You should definitely post your code as a plugin. While I don't think
this is widely-needed enough to be in core (considering that Safari

those that want it.

[jQuery] SpinButton Plugin updated


The SpinButton / SpinBox Plugin has been updated with heaps of improvements
by a splendid chap from this forum named Mark Lincoln.

The SpinButton Plugin takes ordinary input type='text' boxes and turns
them into SpinButton controls using just css and JS/JQuery. No extra markup
is added so the textbox submits and otherwise conducts its life just like
any other.

Usage: $(#myInputElement).SpinButton(mySpinButtonOptions)

Cheers all,

George

 - Mark - Thanks for the code update. Great stuff. It pretty much worked
as-is. All I've added are checks to stop it barfing when the
options-parameter is not provided.

  Matt, can you confirm?

Here's a skeleton of another way to approach the problem. Instead of
enumerating every element inside the form, it looks at each nodeName as it
goes and decides what to do from there.

This code is off the cuff and incomplete! :-)

$.fn.serialize = function() {
   var a = [];
   var taggers = {
  '#COMMENT':ignore, '#TEXT':ignore,
  INPUT:add, TEXTAREA:add, SELECT:select
   };
   
   this.each( function() {
  fields( this );
   });
   
   function fields( e ) {
  var tag = e.nodeName.toUpperCase();
  ( taggers[tag] || nest )( e );
   }
   
   function nest( e ) {
  for( e = e.firstChild;  e;  e = e.nextSibling ) {
 fields( e );
  }
   }
   
   function ignore( e ) {
   }
   
   function select( e ) {
  // not sure if you just want selectedIndex or go get the OPTION
  a.push({ name:e.name, value:e.selectedIndex });
   }
   
   function add( e ) {
  // some existing $.fn.serialize code goes here, ending with...
  a.push({ name:n, value:e.value });
   });

[jQuery] $.fn.updateIfModified problems

2006-09-27 Thread Lewis, David

I want to be able to have a progress bar periodically updated after a
button is clicked, then when the server-side task is complete - the
progress bar is no longer updated (to avoid hammering the server). I
have attempted to write a plug-in that extends the functionality of the
AJAX library loadIfModified() function. This plug-in allows the contents
of a div to be periodically updated after a defined interval. The
plug-in should also allow the update to be cancelled, however I have not
been able to successfully implement this. Any suggestions how to fix
this?


Here's my code:

var intervalTracker = new function() {};
$.fn.updateIfModified = function (options) {
// default settings
this.defaultSettings = {
name: 'noName',
url: '/',
interval: 5000
};

// merge the options with the default settings
var settings;
if (options) {
settings = $.extend(this.defaultSettings, options);
} else {
settings = this.defaultSettings;
}

// if the interval is negative, clear it
if (settings.interval  0) {
if (intervalTracker['interval_' + settings.name]) {
clearInterval(intervalTracker['interval_' +
settings.name]);
}

// otherwise create a new interval and add to tracker
} else {
intervalTracker['interval_' + settings.name] =
setInterval(function() {
$(this).loadIfModified(settings.url);
}, settings.interval);
}

return this;
}

Here's how I start the updating:
$('status-container').updateIfModified({name: 'pollStatus', url:
'status.jsp', interval: 1000});

... and here's how I would like to cancel the updating:
$('status-container').updateIfModified({interval: -1});

the tab doesn't select.

Also, if you load the page and #section-5 ( or whatever the hash might be )

this correct behavior? I was expecting to be able to bookmark a specific tab

They are not yet documented: There is no way to add inline documentation

Anyway, your plugin offers enough good stuff without them, too :-)

Re: [jQuery] Debug Plugin

 I'm currently down-and-out with a nasty cold, but I took a break and

Ah, at last! :-)
 Source Code:
 http://john.jquery.com/plugins/debug.js

 Quick test page:
 http://john.jquery.com/jquery/test/float.html

 Same page, but with a selector error (once you click the middle box):
 http://john.jquery.com/jquery/test/float2.html

 It prints out debugging information for all jQuery functions (e.g.
 $(), $().find(), $.trim(), etc.) using Firebug's console logging. It's
 obviously quite primitive, and the code is really bad, but it's
 something for now. I figure we can take this and hack it out into
 something good.
   
Wow. Sick or not, you are always good for a decent surprise. That looks 
like it could boost jQuery development productivity quite a lot. No more 
adding of console.debug(this) statements everywhere while developing :-)

One thing I noticed after a quick look: The default output for functions 
is pretty useless.
When it outputs something like $.find #mid undefined, it states that 
the context for the search is not given, right? Seems like a vast 
playground with lots of space for ideas and improvements.

[jQuery] Interface Slide bug

2006-09-27 Thread Carlos Aguayo


Using the 'SlideInDown' from 'Interface':
http://interface.eyecon.ro/demos/ifxslide.html
If I have a container absolute positioned, and instead of using 'top' and
'left' properties, I use 'right' and 'bottom', so the container attaches to
the bottom right of the screen, the slide breaks. 
It still slides the container, however, it positions it in the top left
corner of the screen.

Re: [jQuery] ajax bug or I am really confused?

the comment nor  the original code  made any sense to me, I suggest

xml.overrideMimeType('text/xml');

in place,  or in addition(if that code was supposed to do something).

Can you explain why processing elements in semantic order is important?

Re: [jQuery] Form plugin's serialize(): performance issues

 If you say jQuery doesn't support the OR selector '|',  then I'm
 confused. I have a form with one SELECT element and several INPUTs.
 Check out the following results from Firebug:

  $('INPUT', $('#myform')).length
 6
  $('INPUT|SELECT', $('#myform')).length
 7

 That's what I expected as a result.. can you explain?

Oh... well, I'll be:
if ( !t.indexOf(,) || !t.indexOf(|) ) {

Apparently I treat a | just like a , - which is odd and incorrect. I
must've added that a long time ago and forgot about it. The result of
each operator should be something like:

For ',' (AND): input, input, input, select
For '|' (OR): input, input, select, input

The problem is that doing an 'OR' search with the DOM is hard
(certainly not as easy as doing an AND).  So, for now, I'd recommend
migrating your '|' usage to ',' - as it probably won't work as you'd
expect it to, for forever.

Re: [jQuery] When / how did you find out about jQuery?

Same here with Glen, i'm using Moo.fx before JQuery...mostly on intranet
projects. Anyway, being a UI guy... my knowledge on Javascript isn't
good but because of library like JQuery, i'm starting to learn more of
javascript/ajax stuff combined with CSS for presentation...

Thanks to JQuery community... c,)

Re: [jQuery] Form plugin's serialize(): performance issues

 Can you explain why processing elements in semantic order is important?

Two reasons:

$(input | select).eq(0)

This should access the first matched element of input or select - when
the order isn't important, you'll never know which element will
actually be first. It's important that the element is actually the
first element in the document.

Secondly, when serializing forms, the order of the elements that comes
back is frequently important - having a different order can cause
problems for certain applications.

Re: [jQuery] Form plugin's serialize(): performance issues

2006-09-27 Thread Mike Alsup

Hi Renato,

The reasoning behind keeping the elements in semantic order is to have
the form submit data to the server in EXACTLY the same order as it
would if javascript were disabled.  For many, this is unimportant, but
some folks have server-side code with ordering dependencies.

Re: [jQuery] Form plugin's serialize(): performance issues

2006-09-27 Thread Brian

Perhaps there should be a FastSerialize method, that doesn't guarantee
semantic order, and uses every shortcut to cut down on dom-walking time? 
This way, the developer can choose whether to use the faster method, or
the slower-but-correctly-ordered method.

Re: [jQuery] $().load didn't works ini IE6

2006-09-27 Thread Donny Kurnia

This morning I tried a different approach.
I had a select with id='propinsi', that had a list of province. When
it change, I'd like to change the options in the select with
id='kota'. I use the following code:
script type=text/javascript!--
  $(#propinsi).change(function () {
$(.loader).css(display,inline);
$(#kota).load(workflow/table_query.php, {table: kota,
parameter: this.value}, function()
{$(.loader).css(display,none);});
  } );
//--/script

In firebug, I get Response:
...
option value=30Buleleng/option
option value=31Denpasar/option
...

and it's work well in firefox. But in IE6, I got an empty select. So I
tried a longer method:
script type=text/javascript!--
  $(#propinsi).change(function () {
$(.loader).css(display,inline);
$.get(workflow/table_query_xml.php, {table: kota, parameter:
this.value}, function (r, type) {
  //remove previous element except the first element
  $(#kota).children().gt(0).remove();
  var options = $(option,r);//r.getElementsByTagName(option);
  for (var i=0; ioptions.length; i++) {
var value = options[i].getAttribute(value);
var label = options[i].getAttribute(label);
$(#kota).append(new Option(label, value));
  }
  $(.loader).css(display,none);
} );
  } );
//--/script

In firebug, I get Response:
options
...
option value=30 label=Buleleng /
option value=31 label=Denpasar /
...
/options

and it's work well too. But in IE6(again), I got an empty option only.
Option value seem set, because when I submit the form, it send a
correct value. The length of select now change according to the length
of response it get from server. In the first method, the select seem
always empty, no matter the response it get from server.

Any idea how i get these script work in IE6 ??

[jQuery] New Plugin: mousewheel

2006-09-27 Thread Brandon Aaron

I've finished my mousewheel plugin + docs + test/example.

The example/test page: http://brandonaaron.net/jquery/mousewheel/mousewheel.html
The code: http://svn.brandonaaron.net/svn/jquery_plugins/mousewheel.js
The blog entry:
http://brandonaaron.net/articles/2006/09/28/jquery-plugin-mousewheel
The blog entry is just me rambling a little bit. The inline docs are
probably better.

The biggest annoyance/issue was that Firefox/Mozilla doesn't allow the
DOMMouseScroll event to be cancelable. So I had to hack around it but
finally figured out a way to allow the default to be prevented.

BTW, this uses the $().hover method and it has a bug that I've logged
and supplied a patch for here: http://jquery.com/dev/bugs/bug/222/

As this is my first plugin, if there is anything I should do
differently or any enhancements I could make (or if you find any bugs)
just let me know. :)

Re: [jQuery] New Plugin: mousewheel

Great plugin. Couple recommendation:
- The addition of mousewheelup/mousewheeldown methods.
- The standardization of an event.detail and/or event.wheelDelta (IMO,
I think wheelDelta makes more sense). This way you can access the same
property in all browsers.

Do you still need testing for Opera and Safari? I realize that you
said that Safari didn't work, but I'm sure that there's a couple of us
here who can research into this some more, to find a good
cross-browser solution.

Keep up the great work!
