Re: [jQuery] Re initialise selectables
Did you found a solution yet? I've been asking myself the same question and
tried to fix it, but I didn't succeed.
Anyone who knows how to 'reinitialize' the selectables?
I've prepared a showcase: http://www.peterriet.net/temp/selectables/
Any help would be great! Thanks!

Hi,

the found set afterwards.
function makeSelectable(){
$('#mainWindow').Selectable(
{
accept : 'selectableitem',
selectedclass : 'selecteditem',
helperclass : 'selecthelper'
}
);
}
Though when i make another search and call Selectables again, i still get
the helper class (the div that gets created and shows the nice drag
window) but the new found set can't be selected any more. I guess there is
already a selectables object in the dom and won't overwrite or something.
Anybody knows how to solve this .

[jQuery] Some info on the two Require plugins?
There are two Require plugins in the wiki: http://dev.jquery.com/wiki/Plugins/require--by Jose Paris http://dev.jquery.com/wiki/Plugins/requirex --by Mohd Khairi Lamsah and I'm trying to figure out which is better, if at all. The only real difference I can detect is that Mohd's explicity says it can load plugins in a specified sequence, and with a single statement, whereas Jose's looks like it'll only do one at a time. Is that pretty much it, or am I missing something deeper? If it helps anything, the situation is that I'd be providing a way to integrate jQuery into an application as various modules(base jQ, Interface, etc) that other developers can then make use of. But they don't necessarily know what modules will already be there, so want to also have a way for them to ensure their plugins won't explode if some user hasn't installed a particular plugin yet. Thanks for any details. ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/

Chris,
This is possible, although undocumented -- as there is no graceful
API function to grab the jqModal hash of an element. It is important to
note that jqModal functionality is closely tied to the hash , and each
jqModal-ized element ($(e).jqm()) is assigned a serial which points to
its configuration object within the hash. Conveniently, the hash is
globally available via $.jqm.hash, and an jqModalized element's serial
is available as an expando named _jqm. Thus;
var jqmElementHash = $.jqm.hash[$(jqmElement)[0]._jqm];
would correctly assign (and allow you to play with) the jqmElement's
hash object.
The hash object's properties are documented in the README, but as an
example, here's how you would change a jqModal's onShow callback;
--
// accepts an element (either DOM or jQuery obj)
function changeOnShow(element, newCallback) {
var h=$.jqm.hash[$(element)[0]._jqm];
return h.c.onShow = newCallback;
}
Hope this helps and makes sense!
NOTE; in *early* versions $.jqm.hash was available globally. In newer
(r6-r9?), the hash was moved to the scope of the plugin. In r10 beta
(available on plugin page), the hash is again globally available @
$.jqm.hash. Other minor improvements have been made, including Dimitry's
compressable fixes.
See; http://dev.jquery.com/jquery/jqModal/

Chris,
Sure thing. The last triggering element is stored in the hash as t
(see the README). Also, the hash is passed to the onShow, onHide, and
onLoad callbacks as the first argument. So;
$(e).jqm({onShow: showCallback});
function showCallback(hash) {
// get the triggering element
var trigger = hash.t;
}
Is an example. My previous post shows how to access the hash globally,
so you can see who the last trigger of an jqModalized element was
OUTSIDE any callbacks.
Hope this helps,
~ Brice

I'm not 100% that syntax made it in. That said, I don't think that's
what you're looking for. I think you want to bind a click on body, and
test to make sure that e.target is not the element in question.
$(#n).click(function(e) {
var self = this;
$(#menu).show();
$(body).click(function() {
if(e.target != self e.target != $(#menu)[0]) $

Something like the above has worked for me in the past (obviously with
more code to actually DO what you're trying to accomplish).

Re: [jQuery] $(node).hasClass(...) function
Maybe .hasClass() would be helpful, but keep in mind that .is()
offers /more/ functionalities than .hasClass() would.
For example ...
$('.class').is('#my-id')
$('p').is(':visible')
$('div').is('[a]')
I'm not necessarily opposed to having .hasClass(), but I really love
the flexibility of .is().

Re: [jQuery] Of extendos, metadata and valid XHMTL - Is it ok to add attributes to elements?

[jQuery] Best practices for reattaching behaviours to dynamically loaded content?
As site developers using jQuery, we often attach jQuery behaviours through
an attach function that's registered with $(document).ready();. Typically,
behaviours attach to content identified by jQuery selectors, e.g., id or
class values. This works great for the initial DOM ready state. But how can
we ensure that these same behaviours are also attached to content loaded via
ajax?
Of course, if I'm using all my own behaviours I can simply hack them to
apply to ajax-loaded content. But the question is, how can we structure all
our behaviours in such a way that others can use them for both 'normal' and
ajax-loaded content?
There are two parts to this issue:
_
(a) Behaviours list: How can we know what behaviours need to be reattached?
To reattach all behaviours to newly loaded and rendered content, we need to
know what behaviours exist.
(b) Avoiding duplication: How can we ensure that behaviours are attached
only to newly loaded content?
If we simply rerun the original attachment code, we may end up with multiple
behaviour instances attached to individual elements that the behavours were
already attached to.
_
A concrete example: in Drupal we have various jQuery behaviours that may be
attached to content on page ready: autocomplete text fields, collapsing
fieldsets, etc. These are registered through $(document).ready. If we ajax
load and render new content, though, it doesn't get the behaviours and so is
broken. If we manually call the functions that attach the behaviours, we get
duplicate behaviours (e.g., two icons for collapsing fieldsets).
Issue (b) seems relatively easy to address. One way is by filtering the
jQuery selector by class name and then adding that class to all processed
content:
$('div.mybehavior:not(.mybehavior-processed)').each(function() {
$(this)
...
.addClass('mybehavior-processed');
});
Is this the best way?
Issue (a) is more difficult. We can't rely on what was registered through
$(document).ready() because the jQuery.readyList is emptied after being
used.
One possible approach would be to extend jQuery with array of behaviours.
Here's a rough idea:
jQuery.extend({
behaviors: [],
registerBehavior: function(attachFunction) {
jQuery.behaviors.push(attachFunction);
jQuery.readyList.push(attachFunction);
});
jQuery.each(
attachBehaviors: function() {
var elt = this;
if ( jQuery.behaviors) {
// Execute all of them
jQuery.each( jQuery.behaviors, function(){
this.apply( elt );
});
}
});
Then, for behaviours, we would register them with
$.registerBehavior(mybehaviourAttach);
and then call after ajax-loading content with
$(elt).attachBehaviors();
Is this a good general approach? Are there better solutions? What are people
currently doing to address this issue?

Re: [jQuery] Best practices for reattaching behaviours to dynamically loaded content?
I found that the simplest way to handle all of this is to make use of
the context parameter of jQuery. Basically write your attachBehaviors
function like this:
var attachBehaviors = function(context)
{
context = context || document;
$('a', context).bind('click', ...);
$('#product', context).bind('mouseover', ...);
// etc.
}
Then whenever you load some new content via ajax all you have to do is
to pass a context element as a parameter to attachBehaviors. This will
usually be the element that you updated using ajax ; ).
Let me know if this is good enough for what you are trying to do?

Re: [jQuery] Best practices for reattaching behaviours to dynamically loaded content?
I keep all my behaviours in separate functions. For instance if I had a
fancy table widget I'd have a function called initTable() that contained the
behaviour code. I'd call it initially upon page load, then call it again
when necessary if content has been updated via ajax.
Eg.
$(document).ready() {
initPage(); // misc page stuff that won't be refetched from ajax
initTable();
initOtherStuff();
});
function initPage() {
...
}
function initTable() {
...
}
etc.
Then if I need to refresh something in the table via ajax I just call
initTable() in the callback of my ajax function.

Re: [jQuery] $(node).hasClass(...) function

the is() method is wonderful, I use it quite often. But there are often more
ways to achieve the same things, sometimes it's just a matter of taste.
Anyway - a hasClass method would probably even save a few ms compared to
is() in my opinion, because you don't need to parse stuff.
2007/3/4, Karl Swedberg [EMAIL PROTECTED]:
Maybe .hasClass() would be helpful, but keep in mind that .is() offers
/more/ functionalities than .hasClass() would.
For example ...
$('.class').is('#my-id')
$('p').is(':visible')
$('div').is('[a]')
I'm not necessarily opposed to having .hasClass(), but I really love the

Re: [jQuery] Need some guidance...
Alright... now I've got this working very well.
The only problem I have now is validation.
I normally submit a page back to itself, run some
checks on the form values and throw up any errors messages
before the form processes.
However, with the function CalculateMortgage below, I can't do that.
So I need some input on how to use jQuery for validation.
Is there some info somewhere that will walk me through that?
I need the following validation for form input:
Principal: There must be an entry and it must be a number after
all $ , . are taken out.
Interest: There must be an entry and it must be a number after
a % sign which might be entered is taken out.
Years: There must be an entry and the entry must be numerical.
Can anyone point me to some validation technique info that I could
draw from?
Thanks!

Hi Rick -
This is one of those things I would use ajaxCFC for since it handles
serialization automatically. The idea here is that you need to serialize
the values of your form fields, send them to the server, deserialize,
calculate and put the results into some kind of structure which gets
serialized again and returned to the browser for processing which starts
with deserializing. Dealing with the serialization/deserialization
transparently is what makes ajaxCFC so great.
First, download ajaxcfc here:

.cfc's
in some accessible folder on your web server, then copy everything inside
the /js folder to your javascript repository - I create a subfolder to
keep
it separate: /js/ajaxCFC. That's it for the install.
This sample code should get you started. I stuck the ajax call directly
into the click event on the button, but you could put all of that in a
separate function and then call the function from the click event handler
if
you want.

Re: [jQuery] $(node).hasClass(...) function
.hasClass() would just use .is() (or jQuery.filter) internally. Right
now we're quickly gaining filesize without even adding new features
(only dealing with bug fixes). For now, .is() will have to suit.
Another option would be to add an entry for .hasClass() in the
documentation, but in its details, point the user towards .is()
instead.

Absolutely Karl -
the is() method is wonderful, I use it quite often. But there are often more
ways to achieve the same things, sometimes it's just a matter of taste.
Anyway - a hasClass method would probably even save a few ms compared to
is() in my opinion, because you don't need to parse stuff.
2007/3/4, Karl Swedberg [EMAIL PROTECTED]:
Maybe .hasClass() would be helpful, but keep in mind that .is() offers
/more/ functionalities than .hasClass() would.
For example ...
$('.class').is('#my-id')
$('p').is(':visible')
$('div').is('[a]')
I'm not necessarily opposed to having .hasClass(), but I really love the
flexibility of .is().

Hi,
This is not very obvious, and I guess some people won't notice that

from a developer friendly point of view, I think it would be better
to have addClass/toggleClass/hasClass rather than addClass/
toggleClass/is.
Just my 2c ;)

Hi all,
I was wondering if somebody would be interested in a hasClass(...)

willing to contribute it.

Re: [jQuery] Best practices for reattaching behaviours to dynamically loaded content?
I believe this is the easiest and simplest way to do it.
On 3/4/07, Chris Domigan [EMAIL PROTECTED] wrote:
I keep all my behaviours in separate functions. For instance if I had a
fancy table widget I'd have a function called initTable() that contained the
behaviour code. I'd call it initially upon page load, then call it again
when necessary if content has been updated via ajax.
Eg.
$(document).ready() {
initPage(); // misc page stuff that won't be refetched from ajax
initTable();
initOtherStuff();
});
function initPage() {
...
}
function initTable() {
...
}
etc.
Then if I need to refresh something in the table via ajax I just call
initTable() in the callback of my ajax function.

Re: [jQuery] ISO docs for $.fn ?
Hi Kynn - Documentation on $.extend can be found here: http://docs.jquery.com/JavaScript and information on using $.fn.extend can be found here: http://docs.jquery.com/Plugins/Authoring In jQuery $.fn.extend is used in plugin authoring, adding new methods to jQuery. The relationship in jQuery is like this: jQuery and $ are identical. jQuery.fn and $.fn are identical. jQuery.fn and jQuery.prototype are identical. jQuery.extend and jQuery.fn.extend are nearly identical, but when you pass in a single object of properties, jQuery.extend will extend the jQuery object with properties whereas jQuery.fn.extend will extend the jQuery.fn object (and thus add new methods to the jQuery core). All of that being said, if you're just getting started with jQuery, you're probably not going to have to worry about any of this. --John On 3/4/07, Kynn Jones [EMAIL PROTECTED] wrote: Hi.

Alright... now I've got this working very well.
The only problem I have now is validation.
I normally submit a page back to itself, run some
checks on the form values and throw up any errors messages
before the form processes.
However, with the function CalculateMortgage below, I can't do that.
So I need some input on how to use jQuery for validation.
Is there some info somewhere that will walk me through that?
I need the following validation for form input:
Principal: There must be an entry and it must be a number after
all $ , . are taken out.
Interest: There must be an entry and it must be a number after
a % sign which might be entered is taken out.
Years: There must be an entry and the entry must be numerical.
Can anyone point me to some validation technique info that I could
draw from?
Thanks!

function CalculateMortgage(){
var Params = {};
// select all inputs of type text
$(input:text).each(function(){

// post the form. The Param object mimics form fields
$.post(/path/to/yourdatapage.cfm, Params,

Hi, Daemach...
Thanks for the guidance, but unfortunately, I'm still using
CF 4.5, so CFC's are obviously not an option. I plan to
upgrade this summer to CF 8 and catch up with everyone.
I was looking over your code, too... that complicated stuff!
(For someone just starting out, anyway...) After looking over
the code, I can begin to see how it's being done... just wish
I could use AjaxCFC!
Thanks for your time and help!

Hi Rick -
This is one of those things I would use ajaxCFC for since it handles
serialization automatically. The idea here is that you need to serialize
the values of your form fields, send them to the server, deserialize,
calculate and put the results into some kind of structure which gets
serialized again and returned to the browser for processing which starts
with deserializing. Dealing with the serialization/deserialization
transparently is what makes ajaxCFC so great.
First, download ajaxcfc here:
http://www.robgonda.com/blog/projects/ajaxcfc/download.cfm
in the zip file drill down to ajaxCFC/branches/jquery/core/. Put the
.cfc's
in some accessible folder on your web server, then copy everything inside

Re: [jQuery] ISO docs for $.fn ?
This info couldn't have been more timely for me, as soon as I started playing with jQuery my first reaction was to mix in my homebrew code. It was very easy, although now I'm trying to extend it and the distinctions you gave were great. One question though: is there a proper way to check for a preexisting member or method (other than typeof)?
