[jQuery] Re: missing ( before formal parameters
missing ( before formal parameters
$(#postcode).change(function{$(#town).val(zipToCityHash.$(#postcode).val()...
Also, I see what you're trying to do there, but you can't access object
properties like that. You probably want something like:
$(#postcode).change(function() {
$(#town).val(zipToCityHash[$(#postcode).val()]); });
Plus, you don't need to select #postcode again. You can access it with
'this' in the event handler:
$(#postcode).change(function() { $(#town).val(zipToCityHash[this.value]);
});
And, if the user enters a zip that isn't in your hash, val() will get passed
undefined, which does the same thing as calling val() with no arguments: it
returns the current value without changing it. So if you want to change or
clear town if the user enters a zip that isn't in your hash, you could do
something like:
$(#postcode).change(function() {
if(zipToCityHash[this.value]) {
$(#town).val(zipToCityHash[this.value]);
} else {
$(#town).val(); // clear town, or whatever you want to do in this
case
}
});
Hope it helps.

[jQuery] Re: jQuery.Plugin, first release.
Hi Ariel,
a quick question: did you consider instead to use the selector method
in order to line in the plugins to be lazy loaded?
for instance:
script class=lazy
src=_js/jquery_plugins/jquery.metadata.1.0/jquery.metadata.js
type=text/javascript/script
script class=lazy
src=_js/jquery_plugins/livequery/1.0.2/jquery.livequery.min.js
type=text/javascript/script
script class=lazy
src=_js/jquery_plugins/jScrollPane/mousewheel.js
type=text/javascript/script
script class=lazy
src=_js/jquery_plugins/hoverIntent/jquery.hoverIntent.minified.js
type=text/javascript/script
script class=lazy
src=_js/jquery_plugins/color/jquery.color.js
type=text/javascript/script
script class=lazy
src=_js/jquery_plugins/jScrollPane/jScrollPane.js
type=text/javascript/script
script class=lazy
src=_js/jquery_plugins/jcarousel/jquery.jcarousel.pack.js
type=text/javascript/script
and then
$('head script.lazy').lazyLoad(options) ?
i have no idea whether this is feasible or not, i'm just a UI designer
:) , but if it could work like that, then i'd certainly use it.

$(document).ready(function() {

I do get an alert if I add the suggested alternative:
pre

I ended up on this tutorial after experiencing the same thing on the

Any help appreciated.
[jQuery] Re: jQuery.Plugin, first release.
Hi, First release of jQuery.Plugin, that's the name, it is used to lazy load plugins. The file is only fetched with the first call to the plugin. 1. Why not use existing and tested code like e.g. jsPax (jspax.org) or jsan? 2. Can your code resolve dependencies? 3. Does it work with Browsers that have strange Problems - e.g. there are some Safari Versions that don't evaluate script tags added via DOM after the page has been loaded? 4. Do the plugins need to support your plugin somehow - if not, you probably are not able to resolve dependencies? 5. What happens if a plugin with the same URL is registered twice with different names? Will it be requested twice - the browser cache should resolve that of course, but some browsers are realy bad at that? Reading through your example I came to the oppinion that the user of your plugin needs to write quite some code to get things done. Maybe I have misinterpreted your example, but as much as I can see a similar effect can be achived with a lot less code using e.g. jsPax. Christof
[jQuery] cluetip question
I'd like to set a default style for cluetips in my project. Since I'm
abstracting cluetip for my fellow programmers by wrapping it in PHP, I
don't like to add cluetipClass: 'jtip' to every call.
Can I do something like:
$.cluetip.setup({ cluetipClass: 'jtip' });
$(a.cluetip).cluetip();
$(a.cluetip2).cluetip({ some:other_option });
I tried, but it doesn't work like this now.
A global style would be a major improvement I think, you shouldn't
have to set the style for every cluetip.

Venturing into cluetipe (great stuff), I came across the following. When you want to use both local and Ajax data, you are required to do separate calls. The plugin could be smart enought to handle this. - if there's a rel attribute, use ajax, else go for title attribute - if the title attribute contains splitters, split it - if the first char of the title attribute is a splitter char, hide the title This would make me think of (and make me code) much less calls.

[jQuery] Re: Plugin Authoring Help pt 2
By the way, you'll have trouble if you use defaults like this:
$.fn.myPlugin1 = function(options) {
var myOptions = $.extend(defaults, options);
since that will actually extend the defaults object and your
defaults will be changed whatever was in options for the next time
you use the plugin.
Try
$.fn.myPlugin1 = function(options) {
var myOptions = $.extend( {}, defaults, options);
which creates a new object to accumulate the options.

[jQuery] Re: jQuery.Plugin, first release.
Hi all Thanks for your comments, a little tough but that's cool and positive. I checked jspax. It's a regular package manager like any of those out there (no offense meant). Well, this is different: 1- First of all, do you frequently use jspax for your jQuery plugins ? no one said this plugin is the first of its kind. 2- jspax requires you to organize it all in packages, and require them when the moment comes. It also requires to structure your code with callbacks. When you summon a package, you need to pass in a callback. I tried that some time ago, it's not that easy and makes the code kinda weird. This plugin requires you to register for the plugins, the namespaces they take. You need to specify what functions it adds to $ and $.fn. With this plugin, you can(in most) cases, just register them, and the rest remains the same. You code the way you would do, assuming the plugin is loaded. The first call to a function of the plugin, will actually load it, all the calls made while loading (plus the initial one) will be taken into account. In short: there is no require here. @Alexandre The script idea is smart, but won't work, you need to tell the plugin which names are needed. Maybe using metadata... @Christof (cool name) 2-The code can resolve dependencies, that's the option require which is an array of ids of plugins required, that is all explained in the project page. 3-It should work with all the browsers jQuery claims to fully support. No new technique is used here to load the packages, just jQuery. 4-The only thing you need for each plugin, is the list of functions/ namespaces it registers. That's not much generally, in the paste I added, those are mostly the real namespaces for those 3 plugins. I could add a link to a list of pre made registrations, that I add as I get them reported by plugin owners or users. 5-That's a very specific question, this is the first release, a draft you could say. I don't think this point has much importance. I could for instance check that. But the dev is the one registering, so it's not likely to happen. Well, thanks again for checking.

[jQuery] bizarre width inconsistency between FF and IE using dimensions plugin
hello...
I'm using the dimensions plugin. I'm using UL, LI to generate a
scrolling grid.
#datatableHead ul has my column headers
#datatable is a div that's scrollable
first I set widths for the head and scroller:
$('#datatableHead ul, #datatable').css({width: $(window).width()-20});
then I set my grid rows' width based on the scroller's width - since
its all based on viewport size.
$('#datatable ul').css({width: $('#datatable').width()});
looks perfect in IE - but in FF the width of the #datatable ul is
about 20 px bigger than in IE.
now, please don't say: why use dimensions you should use CSS widths -
trust me I tried all of that, it's not working.
If only i could figure out why FF renders widths differently? I
thought the whole point of dimensions plugin is to make that no longer
matter.
Thanks! (now I shall look over the list and see if I can help someone
else :P )

I have tried this, problem is that the JavaScript returned from callAJAX was not executed. I then did some research and tried a few things: 1. I tried parsing out the JavaScript (displayDiv) from the returned HTML (callAJAX) and adding it to the head tag, which in theory, should be executed. This approach did not work for me because displayDiv writes a div to the page and from the head it would not know where to write the div. 2. I have tried parsing out the JavaScript (displayDiv) from the returned HTML (callAJAX) and executing it with EVAL() but this would not work because the AJAX function would not know where to write the div created within the displayDiv function. I guess what I'm hoping for is some magical piece of code that would tell the browser to parse the page again and execute the JavaScript that was added to the page by the AJAX function.

multiple components on the page (if not initialized yet), then fire 1-
n ajax calls, waiting for the callback and so on.
this leads to a set of functions chained together by callback-calls.
function action() {
if (!$('#comp1').is('.loaded')) {
$('#comp1').trigger('load.comp1', [ cb1 ])
}
if (!$('#comp2').is('.loaded')) {
$('#comp2').trigger('load.comp2', [ cb2 ])
}
if (!$('#comp3').is('.loaded')) {
$('#comp3').trigger('load.comp3', [ cb3 ])
}
if (cb1 cb2 cb3 have been called and returned success) {
action2(action2-callback)
if (action2-callback has been called and returned success) {
// do real business logic
}
}
}
do you know of any patterns to implement these callback-chains more
elegantly?
how do you solve nested, nasty callback-chains?
[jQuery] JQuery Hello world not working
Hi All,
I am new to JQuery. I did the following to get started with JQuery.
1) Downloaded JQuery Uncompressed version. Renamed JQuery.1.2.3.js to
JQuery.js (I do not know whether this is correct! )
2) I followed the tutorial for Hello world and typed the following
code into an HTML file
html
head
script type=text/javascript src=jquery.js
/script
script type=text/
javascript
alert('here');
$(document).ready(function() {
$(a).click(function() {
alert(Hello world!);
});
});
/
script
/
head
body
/
body
/html
After opening this HTML file in IE 7.9, I find nothing on the page,
not even any javascript error. The code is supposed to display a link,
but I do not find any link on the page. Can anyone help me here.

The problem with what you're trying to achieve is that you're looking
for something to *display* the data, whereas my implementation of the
plugin focuses on semantic form integration.
Perhaps the way forward is to add the ability to display decimal
points and accept the input of whole numbers (and at a push, .5s).
How are you going to use this?

[jQuery] Close facebox programatically
Hey folks,
I'm trying out jQuery for the first time on my little project and I am
very excited about all the cool stuff. I'm trying to use the Facebox
plugin as a dialog. It works great so far, but I need a way to close
the dialog programatically instead of having the user click on the
'Close' button provided by the dialog window. The docs for Facebox
indicate that I should be able to do this with the following
statement:
jQuery(document).trigger('close.facebox')
But nothing happens when I execute this statement at all, and I don't
get any javascript errors. Thoughts anyone?

I have tried this, problem is that the JavaScript returned from callAJAX was not executed. I then did some research and tried a few things: 1. I tried parsing out the JavaScript (displayDiv) from the returned HTML (callAJAX) and adding it to the head tag, which in theory, should be executed. This approach did not work for me because displayDiv writes a div to the page and from the head it would not know where to write the div. 2. I have tried parsing out the JavaScript (displayDiv) from the returned HTML (callAJAX) and executing it with EVAL() but this would not work because the AJAX function would not know where to write the div created within the displayDiv function.

[jQuery] Re: Plugin Authoring Help pt 2
You might find it easier to simply create objects that use jquery,
instead of writing a jquery plugin.
The biggest advantage is that you actually have a normal instance of
an object. You can pass this instance to other objects, call other
methods on it... all the usual good stuff. (jquery plugins seem to be
a one-shot deal. you call the method, pass in a bunch of parameters,
and it works. If you need to access that instance again, you can't. i
had this problem with the pagination plugin. i added more elements to
my list, but there was no way to tell the pagination object that the
list was longer. i would have to delete it and recreate it.)
here's the pattern i use. let's say i wanted a 'fancy' textarea box.
function TextBox(opts) {
this.jC = opts.container; // all jquery objects start with a 'j'
this.visible = 0;
};
TextBox.prototype.draw = function() {
this.jC.html('textarea/textara'); // could add lots of
functionality to the textbox. key press handlers, etc.
this.visible = 1;
};
// how you use the object...
$(document).ready(function() {
var txt = new TextBox({container:$('#text')}); // obviously need
an element to be the container.
txt.draw();
});
Works well for me. Maybe one of the plug-in experts can comment on
when it makes sense to write a jquery plugin versus write a normal
object that uses jquery?

Because it's not working. It tells me that jQuery().myPlugin({def1:

However, if I change it so that myFunc is $.fn.myFunc = function()
{ }, then I can, but I have to do it as:
jQuery().myPlugin({def1: 'other_def1', def2:
'other_def2'}).myPlugin.myFunc();
Which I don't like.
None of the tutorials or documentation I can find is clear on this
point, though they do refer to the functions in $.myPlugin as being

I can't chain. And I want to be able to do that.

Hello,
as everything Ajax-related is (mostly) asynchronous every response is

I often have the problem that to do action A I have to initialize
multiple components on the page (if not initialized yet), then fire 1-
n ajax calls, waiting for the callback and so on.
this leads to a set of functions chained together by callback-calls.
function action() {
if (!$('#comp1').is('.loaded')) {
$('#comp1').trigger('load.comp1', [ cb1 ])
}
if (!$('#comp2').is('.loaded')) {
$('#comp2').trigger('load.comp2', [ cb2 ])

do you know of any patterns to implement these callback-chains more

how do you solve nested, nasty callback-chains?

[jQuery] quicktime player and thickbox issue
I have a thickbox modal window, in which I have embedded a wav file.
The wav file is being played through the quicktime player plugin. The
audio plays fine, but when I open a newly created modal window, more
often then not, the player doesn't actually show. Instead I see the
gray overlay that is behind the modal window. I ran across a script
that redraws an element in the window, which supposedly causes the qt
player to be redrawn. However, this method doesn't seem to work for
me. Has anyone come across this issue before? If so, how did you
overcome it?
Here's the code that I tried using without any luck. I put it down just
above the /body tag.
|script type=text/javascript
$(document).ready(function() {
closeButton = document.getElementById(TB_closeWindowButton);
color = closeButton.style.color;
closeButton.style.color = white;
closeButton.style.color = color;
});
/script|
I replaced the element ID with one that I was using in my window.
Thanks!

[jQuery] Re: .html() callback?
I think the OP is adding elements to the dom, and then wondering why
the events for the new elements aren't working.
after adding elements with .html(), you need to add the events. For
example, adding an anchor:
$(#header).html('a href=#yo/a').find('a').click(function()
{ alert('click'); return false; });

Hi everyone,
Like a lot of methods of jQuery, why the .html() doesnt have a
callback?
I need that some javascript load when the dom change with .html()
(append and others too), and some events are attached with the new
elements created by this method. What happens is that sometimes they
are attached and other times not. I thing its due the fact that I
execute this code:
$('#div').html(stuffVar);
$.getScript('newEvents.js');
This work sometimes. I would need one way to accomplish this task like
this:
$(#div').html(stuffVar,function(){
$.getScript('newEvents.js');
});
This way, we would have sure that the html is updated and so we can
load the script to attach events.
Anyone has idea???

You might find it easier to simply create objects that use jquery,
instead of writing a jquery plugin.
The biggest advantage is that you actually have a normal instance of
an object. You can pass this instance to other objects, call other
methods on it... all the usual good stuff. (jquery plugins seem to be
a one-shot deal. you call the method, pass in a bunch of parameters,
and it works. If you need to access that instance again, you can't. i
had this problem with the pagination plugin. i added more elements to
my list, but there was no way to tell the pagination object that the
list was longer. i would have to delete it and recreate it.)
here's the pattern i use. let's say i wanted a 'fancy' textarea box.
function TextBox(opts) {
this.jC = opts.container; // all jquery objects start with a 'j'
this.visible = 0;
};
TextBox.prototype.draw = function() {
this.jC.html('textarea/textara'); // could add lots of
functionality to the textbox. key press handlers, etc.
this.visible = 1;
};
// how you use the object...
$(document).ready(function() {
var txt = new TextBox({container:$('#text')}); // obviously need
an element to be the container.
txt.draw();
});
Works well for me. Maybe one of the plug-in experts can comment on
when it makes sense to write a jquery plugin versus write a normal
object that uses jquery?

Can I?
Because it's not working. It tells me that jQuery().myPlugin({def1:
'other_def1', def2: 'other_def2'}) is not a function.
However, if I change it so that myFunc is $.fn.myFunc = function()
{ }, then I can, but I have to do it as:
jQuery().myPlugin({def1: 'other_def1', def2:
'other_def2'}).myPlugin.myFunc();
Which I don't like.
None of the tutorials or documentation I can find is clear on this
point, though they do refer to the functions in $.myPlugin as being
user-accessable... and they are, but only if I do $.myPlugin.myFunc.
I can't chain. And I want to be able to do that.

Without seeing your page, I would guess it may have something to do with the

Subject: [jQuery] bizarre width inconsistency between FF and IE using
dimensions plugin
hello...
I'm using the dimensions plugin. I'm using UL, LI to generate a
scrolling grid.
#datatableHead ul has my column headers
#datatable is a div that's scrollable
first I set widths for the head and scroller:
$('#datatableHead ul, #datatable').css({width: $(window).width()-20});
then I set my grid rows' width based on the scroller's width - since
its all based on viewport size.
$('#datatable ul').css({width: $('#datatable').width()});
looks perfect in IE - but in FF the width of the #datatable ul is
about 20 px bigger than in IE.
now, please don't say: why use dimensions you should use CSS widths -
trust me I tried all of that, it's not working.
If only i could figure out why FF renders widths differently? I
thought the whole point of dimensions plugin is to make that no longer
matter.
Thanks! (now I shall look over the list and see if I can help someone
else :P )

[jQuery] ASP.NET GridView: losing tablesorter on postback
(I apologize for the ASP.NET WebForms terminology)
I'm using ASP.NET's GridView to generate a table, and the jQuery
Tablesorter plugin to sort it (awesome plugin, BTW).
After the page loads sorting works great, but if I click on any
control that performs a postback the page reloads but tablesorter
doesn't affect it (no sorting, css styling, etc.)
When troubleshooting it I click a control that does a postback and the
table loses sorting. I load the table in Firebug's console - it has
the 'tablesorter' method, and I call it, but nothing happens.
$(#ctl00_ctl00_MainContentPlaceHolder_MainContentPlaceHolder_GridView1).tablesorter()
Calling it with '$(...).tablesorter({debug:true})' doesn't print
anything to the console either.
Does anyone have any ideas?
Thanks!

Much like how jquery keeps the javascript out of the HTML, it's so much cleaner to keep PHP out of the HTML as well. Have a look at the Smarty templating system for PHP. It's awesome. that's absolutely pointless, to start a new templating-engine-for-php- rant ... ;) php itself is a templating-language, it's fine to divide your application in tiers like MVC but still php is absolutely wonderful as *the* language to be used in the view. unless you have stupid UI- designers who think it's easier to learn yet-another-ugly-templating- language than to use simple php-syntax... i would stick to multi-dimensional arrays pushed via json, which is fairly lightweight. just my 0.02 euros ...

quite dangerous to call jquery heavy in this group, as it's one of

but if you do not want to use jquery, just download the source and
check the getscript-method, the main-parts should get you going.
generally i think you need to pass some scope to your ajax-called-
script which returns the java-script.
then you may create a Map[scope_identifier] - [dom-target] and use
that map when the jscript gets returned.
of course the returning jscript has to transport the scope-identifier
somehow, SCOPE_ID = 23623623... should be enough...
when trying to defeat xss-protection of the browser, i think most
people use hard-coded callback-functions like:
script returned by ajax-called-script
__xss_callback(function() {
code to execute
});
/script
function __xss_callback(dlg) {
// set right scope
dlg.apply(scope, )
}
i hope this gets you going

[jQuery] jQuery AJAX Dynamic File Download
I've got an export functionality built into my site, whereby users can
choose which rows of a data table to export. They export by clicking

call that posts which ids to export to a PHP script, which, in turn,
builds an Excel document on the fly and delivers it to the user.
Here is my code:
input type=checkbox id=selected1 name=Interviews[] value=21 /
input type=checkbox id=selected2 name=Interviews[] value=22 /
...
inputs = [];
$(#dataTableBody input[id^=selected]:checked).each(function() {
inputs.push(this.name + '=' + escape(this.value));
});

type: POST,
data: inputs.join(''),
url: /gateway/excel.php,
success: function(){
return true;
},
error: function(XMLHttpRequest, textStatus, errorThrown){
return false;
}
});
In Firebug, I'm getting the data in TSV format, but I'm not being
presented the download dialog within my browser. If this was a
straight file download, I would link directly to it, but the file has
to be built dynamically. Can I set the dataType option in the ajax

[jQuery] Re: how to get the size of the image file before user upload it.
Hi all, I've had lots of run-ins with this sort of problem - lol - and basically ... 1: PHP cannot determine anything about a file until it has it on the server 2: Javascript can create an object, and fill it, and then check the size BUT the file also needs to be on the server which just leaves Flash - which kind of does the same thing, it uses actionscript to 'replace' the contents of a movie clip with the image and then waits till its loaded and then asks how big it is (dimensions). Flash is the only known way to get any dimension related information from an image before it is uploaded. What most people do is let clients upload an image and then use php to delete it (or GD library to modify it) if it doesnt meet your criteria. Unfortunately this means that clients can still innocently upload a HUGE image straight off their camera etc and have to wait for the upload process to complete before you can let them know it was all for nothing :-( Since flash can talk to javascript, the best way is to write a generic flash file that javascript can call - get the dimensions and report back to js - and then relay any information necessary to the client or upload the file.

[jQuery] Re: Execute JavaScript that is added to the page by AJAX?
if you load the minified or packed version of jquery, and have gzip compression on your server (which everyone should have anyways), jquery is only around 15kb! is that heavy?

I have tried this, problem is that the JavaScript returned from callAJAX was not executed. I then did some research and tried a few things: 1. I tried parsing out the JavaScript (displayDiv) from the returned HTML (callAJAX) and adding it to the head tag, which in theory, should be executed. This approach did not work for me because displayDiv writes a div to the page and from the head it would not know where to write the div. 2. I have tried parsing out the JavaScript (displayDiv) from the returned HTML (callAJAX) and executing it with EVAL() but this would not work because the AJAX function would not know where to write the div created within the displayDiv function. I guess what I'm hoping for is some magical piece of code that would tell the browser to parse the page again and execute the JavaScript that was added to the page by the AJAX function. I am posting this on behalf of a friend who is to busy today :) If anyone can tell me if this is even possible, and if so, where to go next, that would be most excellent! Many thanks, - Jonny
[jQuery] Re: Problem Targetting DIVs (Dynamic List Example)
In reply to my own mail, replacing:
#QuickLinks gt; div:first
With
#QuickLinks div:first-child
Seems to do the trick.
Is this an acceptable fix?
I'm interested to know if this was a browser (IE6/7, Firefox) issue or
something in jQuery that I need to be aware of.

$(select#QuickLinksSelect).change
(
function()
{
var selectedQuickLink = # +
$(select#QuickLinksSelect).val();
ShowOrHideQuickLinks(selectedQuickLink);
}
);
});
function ShowOrHideQuickLinks(quickLinkToShow)
{
// alert gives [object Object] on load, which is not
expected.
// alert gives #0 or #1 on select change, which is.
alert(quickLinkToShow);
$(#QuickLinks div).addClass(hide);
$(quickLinkToShow).removeClass(hide);

I have a thickbox modal window, in which I have embedded a wav file.
The wav file is being played through the quicktime player plugin. The
audio plays fine, but when I open a newly created modal window, more
often then not, the player doesn't actually show. Instead I see the
gray overlay that is behind the modal window. I ran across a script
that redraws an element in the window, which supposedly causes the qt
player to be redrawn. However, this method doesn't seem to work for
me. Has anyone come across this issue before? If so, how did you
overcome it?
Here's the code that I tried using without any luck. I put it down
just above the /body tag.

I replaced the element ID with one that I was using in my window.

[jQuery] Jörn's autocomplete: submitting to a functi on
For reasons beyond my control I am finding myself needing to send an Ajax request to a different plugin that is not jQuery (ajax4jsf). Another Ajax related plugin I use allows for submitting information to a function, which we used as kind of a gateway between the two systems. I call the function with the needed info, the function posts to ajax4jsf. I have already spent some time trying to retrofit autocomplete to allow submitting to a function, but just wanted to check in to make sure I'm not trying to do something that is already in the works, or that someone has done on the side. Any tips on existing efforts, or best ways to accomplish this would be appreciated. Thanks, Aaron Barker

Do you want to use a function that provides the data for the autocomplete list? Or call the function with the selected value as an argument? The latter is possible using the result-method: http://jquery.bassistance.de/api-browser/plugins.html#resultFunction The first option needs modifications or some trickery.

[jQuery] Re: Multiple Selector Iterator short-cut
If it's an id with a prefix (let's say the prefix is blah) then you
could write:
$('[id^=blah')
Be aware though that this will could be low as it will effectively
check the id of _every_ element on the page. If you can narrow down
the type of the element you're looking for, say to a DIV, then you
could write a much faster:
$('div[id^=blah]')
