I have this piece of code that took me a while to do it and I don't
know if it's the best way to achieve this. First, I'll explain exactly
what I want to do.
I'm using lots of jQuery plugins and I don't want to include them all
with script in the head of every html page. And I want to load
these plugins for every page that needs them but I don't want to load
plugins that some specific page isn't going to need.
To load these plugins I'm using the jQuery built-in $.getScript()
method and I want to use the callback to load the next script in
succession. This way, I'll load one script at a time, meaning, the
second script will only start to load when the first finishes and so
on. But, when the last plugin finishes loading, I want some other
function to be called, in this sample initAdministratio(). Which is
basically the function that will start all the required code by my
application after all necessary scripts for that page are loaded.
On this example, I have 3 plugins to load, and only 2 different pages.
One of the plugins is used by both pages, the other two depend on the
page to be load. One of the pages has a form with ID = form-login
which needs the form plugin, while the other page is the main page and
doesn't need the form plugin but needs the color plugin. Although I
only have 2 pages on this example, I will probably have more in the
future, a lots more. Some of them might need the same plugins as
others which will make them fall in the same if() statement, while
others don't and I will need to add an else if() statement. The last
else statement will always be the default page to load. Meaning, if no
specific page was found to load some specific plugins, then, just load
the default ones.
Now, the code:
$.extend($.browser, browserVersion);
var loadJSLibs = function(libsList) {
var libName = libsList.shift();
var callback = function() {
if (libsList.length 0) loadJSLibs(libsList);
else initAdministratio();
}
$.getScript(libsPath + libName + .js, callback);
}
if($('div#form-login').length) {
var libsList = [
'jquery.simplemodal',
'jquery.form'
];} else {
var libsList = [
'jquery.simplemodal',
'jquery.colors'
];
}
loadJSLibs(libsList)
Basically, I want to know if there's anyway to improve this piece of
code, somehow. As I've told you before, I took a while to do it as I
don't have much JS experience which will probably make me fail to see
things that experience JS programmers would not.

[jQuery] [tooltip] Looping and variable tooltip setup
Greetings,
After evaluating several different javascript tooltip libraries I've
settled on the jQuery 'Tooltip' plug-in, however I'm having one minor
issue getting something working.
I'm trying to setup a series of pairs of tooltip triggers/bodies using
a generic naming system so that it's easily enable through CGI
scripts.
To test I have two sets of triggers/bodies that look like this:
table
tr
td
div id=tt0Item 1/div
div id=tb0 class=tbItem 1's Tooltip/div
/td
td
div id=tt1Item 2/div
div id=tb1 class=tbItem 2's Tooltip/div
/td
/tr
/table
Where the div with the 'tt?' ids are the tooltip triggers and the
'tb?' ids are the associated tooltip bodies.
Now, if for each pair I add the following jQuery script the results
are fine:
$(function() {
$(#tt0).tooltip({bodyHandler: function(){return $
(#tb0).html();}});
$(#tt1).tooltip({bodyHandler: function(){return $
(#tb1).html();}});
});
I get the appropriate tooltip bodies when the mouse hovers over the
triggers.
The pages that will be generated however will have dozens of tooltips
and to have one of these for each would end up causing a lot of
overhead in the output, so to alleviate this output overhead I'd like
to have a loop that will dynamically perform that. Currently I have
the following code:
$(function() {
var tc = $('[id^=tt]').size();
for (var i = 0; i tc; i++) {
var tt = #tt + i;
var tb = #tb + i;
$(tt).tooltip({bodyHandler: function(){return $
(tb).html();}});
}
});
This does create tooltips for the two triggers, however both of them
have the tooltip body from 'tb1', I've verified that the values for
the 'tt' and 'tb' variables are correct during the loop, and
the .text() values from the bodies also show the correct values.
Is there something I'm missing from this, or am I going about this the
wrong way?
I would appreciate any comments or suggestions!
Thanks,
Derek R.
[jQuery] [validate] Does the validation plugin support required hidden inputs?
Hi, does the validation plugin support required hidden inputs? I have two input fields: field1 (text) and field2 (hidden). When i change the text od field1 a js-function is called and the value of the hidden field2 is changed (or not if the text in field1 is the wrong one). In jquery.validate i have set a rule for field2 (required). When i validate the form and field2 is empty it shows me an error message - that's good! When i change the field1 text (right one now), the field2- value is set but the error message doesn't disappear (because the field2 is hidden and fires no onchange-event). How can i solve this problem? cu rigo

[jQuery] Issue with $.getScript() and $(window).load() - Not working!
Hi,
Here's the thing, I'm using the SimpleModal plugin to show a modal
dialog on my page. It doesn't really matter which plugin I'm using.
Well, I think it doesn't but I haven't actually tested any other
plugins in this scenario.
When you load any page, the modal dialog will be opened at $
(document).ready(). The idea is to show a modal dialog saying that the
page is loading. Then, at $(window).load() I close the modal dialog
cause this event will be fired as soon as the page stopped loading.
The thing is, this works fine if I load the plugin (the
jquery.simplemodal.js file) in the head of the document with a
script tag but if I use $.getScript() to load the plugin, it won't
work. Well, the modal dialog will be shown, but it won't be closed at $
(window).load(), this is the problem I'm having. And yes, I'm using
callbacks with $.getScript() but I don't think it does any good
because $(window).load() will actually be called before it should...
One last thing, for Firefox, it doesn't matter if I'm loading the
plugin in the head or if I'm using $.getScript, it will just work.
But on IE7, it only works when the script is loaded in the head.
Now, my code is something like this:
$(document).ready(function() {
$.getScript(jquery.simplemodal.js, function() {
$('#simpleModal').modal();
});
});
$(window).load(function() {
$.modal.close();
});
Is there in way to fix this? I have no idea how to...
[jQuery] Re: [tooltip] Looping and variable tooltip setup
derek,
i haven't thoroughly examined how bodyHandler works but i think
something like this should work, provided that your html structure won't
change:
$('div[id^=tt]').tooltip({
bodyHandler: function(){
return $(this).next().html();
}
});
if your html structure will change, you could do something like this:
$('div[id^=tt]').tooltip({
bodyHandler: function(){
var id = 'tb' + this.id.substr(2);
return $('#'+id).html();
}
});
although i'd recommend using classes instead of id's, to avoid
cluttering your html (and then using something in the lines of the first
example, only instead of $('div[id^=tt]') you could use $('div.tt'), and
of course, putting a tt class on the 'item' divs ) ..

[jQuery] Mac OS X default system drag and drop is overriding Interface's drag and drop
Hi all, I'm developing a back end for a photographer's agent, and she wants the site to be mainly drag 'n' drop thumbnail images, so she can create collections of various images, by dragging from various bins. So I've started with a styled ul list of images, and each li contains an img. Each img aligns to the middle of it's li so the whole thing looks like a grid of slides. I'm using the Interface plugin and it's all working great; I can grab the lis and it's easy to re-arrange them. However - with the Mac, when you go to click on the li the browser intercepts the click on the img and thinks you want to drag the image to your desktop! Any functionality gained through Interface is lost. Does anyone have any solutions? I'm going to look at placing some kind of div over the top, but I wanted to ask here first. Cheers, Dave

[jQuery] Re: trying to find the first instance of a person's name on the page
Well regexp would be useful if there was a pattern to people's names, but there isn't. Do you want to find any names, or a list, or a specific name?
[jQuery] Re: .find does not work in .each
Not sure, but from an id/class point of view, any page id should be unique, so your order identifier if it is to be used on many TDs, should really be a class=order. So if you're just picking up a single id, there's no need to iterate over, is there? Anyway - I replicated your test and find worked fine within each for me.

That's a good point, but it looks like he is trying to find td elements with an id that *starts* with order, so they could be order_1, order_2, etc. I agree, though, that it would be less cumbersome to simply use a common class.

[jQuery] Re: [tooltip] Looping and variable tooltip setup
dennis,
Thanks for the help, both of your examples work great.
I also tried substituting in a class 'tt' in place of the individual
ids and that seems to work good as well.
Is there any speed advantage to this method? I'll probably end up
using this method instead as it seems more elegant.

Where the div with the 'tt?' ids are the tooltip triggers and the
'tb?' ids are the associated tooltip bodies.
Now, if for each pair I add the following jQuery script the results
are fine:
$(function() {
$(#tt0).tooltip({bodyHandler: function(){return $

$(#tt1).tooltip({bodyHandler: function(){return $

});
I get the appropriate tooltip bodies when the mouse hovers over the
triggers.
The pages that will be generated however will have dozens of tooltips
and to have one of these for each would end up causing a lot of
overhead in the output, so to alleviate this output overhead I'd like
to have a loop that will dynamically perform that. Currently I have
the following code:
$(function() {

for (var i = 0; i tc; i++) {
var tt = #tt + i;
var tb = #tb + i;
$(tt).tooltip({bodyHandler: function(){return $
(tb).html();}});
}
});
This does create tooltips for the two triggers, however both of them
have the tooltip body from 'tb1', I've verified that the values for
the 'tt' and 'tb' variables are correct during the loop, and
the .text() values from the bodies also show the correct values.
Is there something I'm missing from this, or am I going about this the

[jQuery] How to select an element based on visibility
Hi,I cannot get my finger behind this one:
I have this HTML:
p class=firstLineThis is the first line of the first paragraph/p
pAnd here is some more text. Bladibladibla/p
p class=firstLineThis is the first line of the secons paragraph/
p
pAnd here is some more text. Bladibladibla/p
p class=firstLineThis is the first line of the third paragraph/p
pAnd here is some more text. Bladibladibla/p
when I click a p class firstLine, I want the paragraph immediately
_below_ it to disappear if it is visible. If it is invisible, I want
it to show again.
This
$(document).ready(function(){
$(.firstLine).click(function(){
var el = $(this).next();
$(el:hidden).click.slideDown(slow);
$(el:visible).click.slideup(slow);
});
});
doesn't work.
How can I do this?
Thanks
[jQuery] Re: [tooltip] Looping and variable tooltip setup
derek,
i'm not sure if there are any speed advantages (in both cases jquery has
to loop through all divs on the page to find the ones you need - either
by class or by id, so there probably is none) but by using classes your
keeping your html cleaner..
as a rule, things that repeat on a page or through out the site, and
have the same purpose, should use classes, and things which are specific
and more important should use id's.. or at least, that's the how i do it
:)..

[jQuery] Re: .find does not work in .each
it looks like he is trying to find td elements with an id that *starts* with order, True! But the jquery was good. So not sure what was going on there. Sometimes you just need to delete blocks of code and write from scratch, as you just can't what's not quite right (the brain sees what it wants to!). Maybe this is one of those times!
[jQuery] Re: How to select an element based on visibility
You're very close. The .slideToggle() method will slide down if hidden
and up if visible:
$(document).ready(function(){
$(.firstLine).click(function(){
$(this).next().slideToggle('slow');
});
});
Working with your code the way you had it, you could have done
something like this:
$(document).ready(function(){
$(.firstLine).click(function(){
var el = $(this).next();
if (el.is(:hidden)) {
el.slideDown(slow);
} else {
el..slideup(slow);
}
});
});
You could also use a ternary operator to abbreviate the code a bit:
$(document).ready(function(){
$(.firstLine).click(function(){
var el = $(this).next();
el[el.is(:hidden) ? slideDown : slideUp](slow);
});
});
Hope that helps.

[jQuery] unbind LocalScroll?
Wondering if anyone can help me with the LocalScroll plugin: I'm using the LocalScroll plugin and would like to programmatically unbind it from the nav links and target so that I can modify the set of links and the target, then rebind it. I tried using the lazy:true setting, but I found that I was not able to programmatically fire .click() events on the nav links (which I'm doing for some custom next/prev stuff) when lazy = true. I'm thinking that if I can unbind it, then rebind it, what I'm trying to do will work. The functionality is a set of links/target that change after someone logs in (the login is performed via ajax, so the page does not reload). If not unbinding/rebinding, maybe there's another/better way? Thanks, Jack

[jQuery] jquery form plugin submitting for multiple times after DOM is appended
I'm using the jquery form plugin from a form which is retrieved via
ajax. I have multiple forms on the page.
I'm using .livequery to make sure the form is only requested once, but
didn't realize my problem is that the submit is actually occuring more
than once.
I've tried adding .livequery to the begging of the .submit function so
that it would hopefully only be triggered once, but that hasn't worked
for me.
I would prefer to not do an 'unbind/bind' function because with
cancelling of the form, etc. it gets a bit complicated.
Is there a simple way to do this?
Here is the code I have to call the form and then to submit it. This
code includes my attempt to use livequery in this, but the form still
submits multiple times.
[code]
$(.addGroup).livequery('click', function(event) {
id = this.id;
var posTop = event.pageY;
var posLeft = event.pageX;
var formID = #createForm;
$.ajax({
type: GET,
url: processes/addType.php,
data: gid=+id,
success: function(response){
$(formID).css({ position: 'absolute',
top: posTop, left:
posLeft });
$(formID).fadeIn(slow).html(response);
$(#createForm).livequery('click',
function(){
addShiftAJAX();
});
cancelForm(formID);
templateShifts();
}
});
});
// prepare the form when the DOM is ready
function addAJAX(){
var options = {
target:'#createForm', // target element(s) to be
updated with server response
success: showResponse
};
// bind to the form's submit event
$('#createForm').submit(function() {
// inside event callbacks 'this' is the DOM element so we
first
// wrap it in a jQuery object and then invoke ajaxSubmit
$(this).ajaxSubmit(options);
// !!! Important !!!
// always return false to prevent standard browser submit and
page navigation
return false;
});
// pre-submit callback
function showRequest(formData, jqForm, options) {
// formData is an array; here we use $.param to convert it to a
string to display it
// but the form plugin does this for you automatically when it
submits the data
var queryString = $.param(formData);
// jqForm is a jQuery object encapsulating the form element. To
access the
// DOM element for the form do this:
// var formElement = jqForm[0];
alert('About to submit: \n\n' + queryString);
// here we could return false to prevent the form from being
submitted;
// returning anything other than false will allow the form submit
to continue
}
// post-submit callback
function showResponse(options) {
// for normal html responses, the first argument to the success
callback
// is the XMLHttpRequest object's responseText property
// if the ajaxSubmit method was passed an Options Object with the
dataType
// property set to 'xml' then the first argument to the success
callback
// is the XMLHttpRequest object's responseXML property
// if the ajaxSubmit method was passed an Options Object with the
dataType
// property set to 'json' then the first argument to the success
callback
// is the json data object returned by the server
$.ajax({
type: GET,
url: processes/getGroups.php,
data: cid=+cid,
success: function(response2){
$(.groups).html(response2);
$(#createForm).fadeOut(slow);
}
});

json, it stops and I don't know why? Any ideas? Are there any problems
with livequery and json?
[jQuery] jqModal - how to call jquery functions on returned AHAH?
Hi,
I'm using jqModal:ajax to load a remote php into a div modal form. So far
so good. But the returned HTML also has some jquery elements. I can't figure
out how to get them to initialize (i.e. the function call that would
otherwise be in the $(document).ready function).
I tried doing something with onload like so:
script
$().ready(function() {
$('#ex2').jqm({
ajax: 'prodtabs2.php',
trigger:'a.ex2trigger',
onLoad: loadAjax });
});
var loadAjax = function(jqmHash) {
$(#productinfo ul).tabs(); // trying to init jquery.ui.tabs
};
/script
I also tried using jqmHash.w as a second parameter, but also to no avail.
Can anyone point me in the right direction?
Thanks.

[jQuery] Re: Using getScript to load an array of scripts with callbacks
As you might already know, there is a nice plugin you can find at
http://www.creativit.com.br/jquery/ondemand_js/index.htm
play with it... you maybe end up understanding a litte more on dinamic
script loading.
But my question remains: As native $.getScript() documentation
noticed(Warning: Safari 2 and older is unable to evaluate scripts in
a global context synchronously. If you load functions via getScript,
make sure to call them after a delay.) , there is an issue when
dynamic loading scripts on Safari 2 and older. Has someone worked-
around it to have a cross-browser fashion to have a callback without
using a delay?

with script in the head of every html page. And I want to load
these plugins for every page that needs them but I don't want to load
plugins that some specific page isn't going to need.
To load these plugins I'm using the jQuery built-in $.getScript()
method and I want to use the callback to load the next script in
succession. This way, I'll load one script at a time, meaning, the
second script will only start to load when the first finishes and so
on. But, when the last plugin finishes loading, I want some other
function to be called, in this sample initAdministratio(). Which is
basically the function that will start all the required code by my
application after all necessary scripts for that page are loaded.
On this example, I have 3 plugins to load, and only 2 different pages.
One of the plugins is used by both pages, the other two depend on the
page to be load. One of the pages has a form with ID = form-login
which needs the form plugin, while the other page is the main page and
doesn't need the form plugin but needs the color plugin. Although I
only have 2 pages on this example, I will probably have more in the
future, a lots more. Some of them might need the same plugins as
others which will make them fall in the same if() statement, while
others don't and I will need to add an else if() statement. The last
else statement will always be the default page to load. Meaning, if no
specific page was found to load some specific plugins, then, just load
the default ones.
Now, the code:
$.extend($.browser, browserVersion);
var loadJSLibs = function(libsList) {
var libName = libsList.shift();
var callback = function() {
if (libsList.length 0) loadJSLibs(libsList);
else initAdministratio();
}
$.getScript(libsPath + libName + .js, callback);
}
if($('div#form-login').length) {
var libsList = [
'jquery.simplemodal',
'jquery.form'
];} else {
var libsList = [
'jquery.simplemodal',
'jquery.colors'
];
}
loadJSLibs(libsList)
Basically, I want to know if there's anyway to improve this piece of
code, somehow. As I've told you before, I took a while to do it as I
don't have much JS experience which will probably make me fail to see
things that experience JS programmers would not.

[jQuery] Re: refreshing a div tag
Steve, I searched around the web a bit for a way to refresh a div tag at set intervals but haven't found anything that pertains to jquery. I saw some stuff about prototype and ColdFusion 8, neither of which were any help. Does anyone have a preferred method of doing this? I'd like to be able to have the div tag refresh at regular intervals and also be triggered by clicking a link or triggering an event. There's a plug-in called Heartbeat you can use repeat an AJAX operation at set interval. To trigger an update manually (via a click event or programmatically) you can use the $.ajax() method. -dan

[jQuery] Re: unbind LocalScroll?
Hi Jack
I haven't added a way to cleanly unbind localScroll as I didn't
thought it would be usual. If that's the case, I can tell you what
element to call unbind on.
jQuery.LocalScroll is prepared to handle dynamic content. That's why
the option lazy is there. If you choose the lazy option, then event
delegation is used. That means that if you do: $
(something).localScroll({lazy:true,..}). The binding is done on that
'something'. And as long as you preserve it, the click on links will
still be caught, if you don't understand what I mean, check the AJAX
demo. The links are renewed on each load and no rebinding is needed.
If you need any more help, mail me to aflesler(at)gmail(dot)com and
I'll help you out.

[jQuery] Re: jQuery is killing my xhtml strict validation
It's not a problem. I assume you're viewing the DOM tree via Firebug (or something similar)? If so then what you're seeing is a representation of the tree that Firebug is generating. The concept of XHTML vs HTML (vs XML) is pretty much gone after the (X)HTML is parsed and turned into the DOM tree. There's no need for keeping around the quotes, '/' or other delimiters as each of the elements now exists as a node, not as some textual representation.

[jQuery] Re: Using getScript to load an array of scripts with callbacks
As much as I appreciate your input and with all due respect, I didn't
ask for a plugin to import JS files. I asked about the code I posted
and if there is a way to improve it. I'm new to jQuery and Javascript
itself and as I took lots of time to do that tiny piece of code I just
thought that it may have something wrong with it and can easily be
improved by someone more knowledgeable than myself...

As you might already know, there is a nice plugin you can find at

play with it... you maybe end up understanding a litte more on dinamic

But my question remains: As native $.getScript() documentation
noticed(Warning: Safari 2 and older is unable to evaluate scripts in
a global context synchronously. If you load functions via getScript,
make sure to call them after a delay.) , there is an issue when
dynamic loading scripts on Safari 2 and older. Has someone worked-
around it to have a cross-browser fashion to have a callback without
using a delay?

[jQuery] Re: unbind LocalScroll?
Also.. you mentioned prev/next links.
Maybe what you need is SerialScroll:
http://flesler.blogspot.com/2008/02/jqueryserialscroll.html
It's pretty similar to LocalScroll, it also has a 'lazy' option, but
it's meant to be used for prev/next situations.

[jQuery] Re: jQuery is killing my xhtml strict validation
OK. Since I'm creating so much of the web site on the fly, there's really no way of knowing whether I'm valid or not, is there? I mean it's pretty easy to make my trivial, skeletal html (or php) file valid--there's hardly anything in it! I tried to go through all the paths and validate. I guess I'm OK if all I get are warnings that complain about the validator seeing an HTML version of the DOM rather than a XHTML version. Oh, and canvas is not valid. Nothing to be done about that, right? On Feb 23, 6:36 pm, Karl Rudd [EMAIL PROTECTED] wrote: It's not a problem. I assume you're viewing the DOM tree via Firebug (or something similar)?

[jQuery] Little problem with ajax perhaps?
Hi, I'm using the jQuery form plugin and SimpleModal plugin and I'm having a little problem that I don't understand why it's happening. As my understanding in the whole thing, this shouldn't be happening and I can't understand why. The thing is, I show a blue popup while the page is loading, it shows on document ready and it hides on window load. Then, you submit a form and the form is submitted by ajax so there is a request and response. On the request I show a blue popup saying the form is submitted and it remains there until the server responds and the ajax response is fired, when it does, the popup will be red and show an error message (when there are errors of course). Then, we close the popup manually. Then, you click refresh or leave the page, I also added the same popup saying the page is loading, this I've done on window onbeforeunload. Now, the problem is on the last popup described. For all the popups (the html elements are the same) I simply swap css colors and content of the elements when needed. However, for the last popup, I didn't change anything and my best guess is that it should have remained with the colors from the error popup and it's message cause it was the last on to be show and so, the html elements have the properties from the las popup. However, the popup is blue and it shows the text messages from the popup that is displayed on the ajax request. Ok, this might sound a little confused so I built a demo that you can take a look here: http://nazgulled.clok.info/test/admin/ It's filled with alert()'s along the way to explain what's happening and where is the problem. Just view the source code of the page, everything is inline (besides the jQuery lib and it's plugins). Please help me out on this, I need to understand why this is happening so I can continue my project and develop it accordingly...
