Re: [jQuery] Re: New Forums
And if you were using a screen reader, and had need to post a question to the mailing list? Then you'd still need to deal with the web page/forums. Your solution is a good step in the right direction, but does not solve the problems. I've looked into integrating a forum and mailing list in the past. Unless something has changed in the past couple of years, there is no good solution. What is needed is a way to keep a mailing list and forum in sync. Messages sent to the mailing list are automagically posted in the forums, with the conversation threads being maintained. Messages posted to the forums are automagically posted to the mailing list. The closest I've ever seen for this is the forums where you can elect to receive an email if a watched topic is posted to. Or if someone replies to you or a topic that you had previously replied to. While this is somewhat workable, it still looses all the benefits of an email list - you still have to go to the web page to view/respond to messages. And visiting the web page is not part of the normal routine for a number of people. Karl said it best - we can't please everyone. Unless someone were to sit down and write a tool to integrate/synch a forum (Zoho in particular in this case) and the mailing list (Google Groups in this case). I don't forsee that happening anytime soon. My thoughts. Shawn John Arrowwood wrote: Silly thought: What if the forums were 'published' to the mailing list, and the mailing list were made read-only? That is, every time a post is published on the forum, it is automatically sent to the mailing list. Then, in the footer of the message is a link to reply to the post, which when clicked takes you to the forum in such a way that the user can immediately reply to that post. The mailing list could be set up so that nobody except the forum 'bot' could post to it, which would make spam go away. People that have accessibility issues or just prefer to get their information via their email client could continue to read things that way. And you would have all of the benefits of the forum. Best of both worlds. Make everybody happy. I know it would make me happier.

Re: [jQuery] New Forums
My apologies to the list managers. I did not mean to belittle their efforts in any way. I only meant to state that for me, personally, forums are not the preferred tool. I am involved in a number of organizations where the main mantra is the concept of a do-aucracy. If you think it should be done a particular way, do it. For this list, this means that the list managers have DONE it, and so they get to make the rules. I don't pretend to know all the considerations that went into the choices that were made. But, I find it unacceptable that I have to give my contact information to zoho.com so that I can use a forum on jquery.com. (as suggested by Andre in a different posting on this thread). For some reason it is deemed ok for our account info (and everything related to it) to be accessible by absolute anyone. Whether it is a FaceBook account, a GMail account, etc. I have put the brakes on for this trend and refuse to give my information away to third party sites that have nothing to do with what I'm trying to do. No offense intended to the zoho gang, as I do not know them or their intentions/purposes. But I'll just say no. My thoughts. Shawn Shawn wrote: I received this email as well.

jQuery(function() {
var MarketCapTotal = 0;

jQuery('#grdWatchlistname tbody tr').each(function() {

var MarketCap = (jQuery('td:nth-child(4)', jQuery(this)).html

var td4th = jQuery('td:nth-child(4)', jQuery(this));
if (!isNaN(MarketCap)) {

Also, your parseInt() function really should specify the radix you want.
You can get some unforseen issues if you don't. So,
MarketCapTotal += parseInt(MarketCap);
would become
MarketCapTotal += parseInt(MarketCap, 10);
Hope that helps.
Re: [jQuery] Anchor navigation /like facebook
I don't think you quite understand what it is you are wanting. Or maybe
I'm just a little t drunk.. :)
navigation like that has nothing to do with Ajax. Using URLs like that
to request Ajax based data/content is something else.
If you really truly mean navigation, then may I suggest just making an
anchor tag with the href attribute set to the desired URL? As in
standard HTML sans JavaScript.
If you mean you want to make an Ajax request to get content without
reloading the page, well, you *could* intercept the click event of the
anchor tag and ask for the data returned by the URL at the href.
Something like this maybe:
$(a).click( function () {
$.ajax({
url: $(this).attr(href),
dataType: html,
success: function (response) {
$(#mydiv).html(response);
}
});
return false;
});
The return false; is important. If you don't stop the normal event
propagation, your page will continue to navigate as if you had clicked a
normal anchor tag.
Anyways, I really don't mean to be condescending. I'm just not quite
clear what you are asking for, and my impression from your message is
that you are not either. Hopefully my feeble attempt points you in the
right direction... :)

[jQuery] Re: js function to jQuery
Does jQuery work when you first load the page, and then it stops
working after any ajax postback within the update panel? If this is
the case there is a pretty simple fix:
instead of using $(document).ready(function() { ...});
use either:
function pageLoad() {
//code goes here
}
or
Sys.Application.add_load(function() {
//code goes here
});
The first can be used if you only need one function call, the latter
is for adding multiple function calls to a page load. I recommend the
latter, since you never know when you may want to separate some js/
jQuery into different external files. The problem is that jQuery
binds its events to everything the first time the page loads, and then
the update panel sends the entire section of html code within it to
the server, and then a new set of html code is returned. This means
that all of the events are no longer bound to the new controls inside
the update panel. In theory you may alternately be able to use $
(#element).live(click... but I've never tested it.

Re: [jQuery] Best Practices or unobtrusive Javascript
The blocking is an issue, but only if you end up loading more than XXX number of elements at a time. The specific number is browser dependent. I think I read somewhere that IE8 and FF3.5 will only load 4 items concurrently (CSS files, JS libraries, images, etc). So, the knee-jerk solution is to minimize your libraries, compress them where possible, enable caching, etc. OR, load a single JS library that will then add the needed elements after the page loads. Sure putting JS at the end of a file, or even in the middle of the file may help with performance, but I would slap my subordinates upside the head (in a friendly manner, of course) for doing that. It makes maintaining pages a pain in the rear, seeing as every other page I've worked on in recent years puts JS in the header (either library includes, or page specific code), AND is contrary to the coding standards for our projects. Writing code that is generally consistent with what others tend to do makes that code much easier to understand and maintain. But I recognize the many ways to do things rule, and don't mean to suggest my way is right. If you have the volume where you *really* need to worry about performance, then the rules get bent anyways and creative solutions are found. Such as merging all JS libraries into one file, then gzipped My random thoughts. Shawn Rafał Pocztarski wrote: 2009/11/30 breadwild breadw...@gmail.com: I have seen several examples on jQuery plugin sites that have the script tag and Javascript within the body and not the head where I thought it was supposed to go. It's a matter of performance. Put your CSS as close to the top of the head as possible, and put your JavaScript as close to the bottom of the body as possible. This is because browsers try to load everything in parallel but block while loading, compiling and executing JavaScript (because it could potentially alter the following HTML - e.g. using document.write). You can try to work around this but if you just want to include script tags in your HTML without any fancy tricks to load scripts using iframes or xhr evals or injections then move your script tags to the bottom of your page.

Re: [jQuery] Best Practices or unobtrusive Javascript
When doing dynamic sites, you sometimes have no choice but to put the JS in the body area. My rule of thumb is to use libraries wherever possible and include those libraries in the head section. But with the understanding that *sometimes* (though rarely these days) I will need to put JS into the body. Take a look at what you are doing with the code that is in the body area. Can that code be wrapped up in a function and called in the $(document).ready() function? If so, then that is probably what you should be doing to make your code more self contained. Building Ajax driven sites sometimes needs the code in the body area though. If you dynamically add a block of elements and need to do something to them the moment they are loaded, then this *might* be a reasonable time to embed JS code directly. Though I tend to use $.ajax() and so can just call a function after adding the elements. Which means I can pre-write that function in a library, with no JS needed in the body area. Clear as mud? :) Shawn breadwild wrote: I have seen several examples on jQuery plugin sites that have the script tag and Javascript within the body and not the head where I thought it was supposed to go.

[jQuery] show/hide ui.tab?

case wellsite: $(#tabWellholes).show(); break;
}

I don't want to add/remove tabs - that is not quite what I'm after. I
just need to hide/show the tabs.

[jQuery] Re: draggable containment
It's been a while since I've worked with drag/drop, so take this with a degree of skepticism But, I believe [x1,y1,x2,y2] refer to the x/y coordinates of the rectangle you'd like dragging contained to. I think you can specify a selector though to say contain the dragging to this object. in which case you can point at a div that holds the item being dragged. Don't know how helpful that is, but hope it is a start... Shawn Mike C wrote: I've spent a good few hours trying to figure this out and I'm stumped.

[jQuery] Re: Your Javascript/Jquery best pratices
When you are working in team environments, a common coding standard is very helpful. What I do is to define the coding standard to be implemented for a project, then do periodic code reviews to make sure the standards are being applied as well as making sure the code actually works and is sound. (after thought - make sure your coding standards define how you'll do indentation - 4 spaces, 1 tab character, etc) Coding standards are common for a number of projects. I thought I had seen one for jQuery but am not seeing it right now. I did find this one for the jQuery.UI - http://jqueryui.pbworks.com/Coding-standards. Drupal has one at http://drupal.org/node/260140, and Zend Framework's is at http://framework.zend.com/manual/en/coding-standard.html (though it is down for me at the moment). Code reviews should be done by someone who has sufficient background with the project to understand the big picture. These reviews should not be done to ridicule anyone - there are syntax/logic issues, and then there are style issues. Where you might use a while loop, someone else may use a for loop - both are right, as long as the syntax and business logic are done right. Don't harp on anyone for style issues, though mentioning it and explaining why you use YOUR style can lead to some interesting discussions and growth for everyone. Regarding best practices, I know there have been a few web postings for jQuery/JavaScript best practices. Here's one: http://www.smashingmagazine.com/2008/09/16/jquery-examples-and-best-practices/ Best Practices and Coding Standards should ALL be subject to the job at hand. That is, don't force the developers to jump through meaningless hoops just to satisfy and administrative requirement. Allow deviations from the target where it makes sense. On the other hand, getting all developers to use a common standard for a project does help quite a bit when collaborating.

[jQuery] Re: ClueTip focus/blur trouble
s close.
Your code works, but due to the unbind of the blur.cluetip event, it
only works once. Which makes sense. So I modified it slightly to the
following. This seems to be working so far.
$this.unbind('blur.cluetip');
$(#cluetip).hover(
function () { $(this).data('hovered', true); },
function () { $(this).removeData('hovered'); }
);
$this.focus( function () {
$(this).blur(function() {
setTimeout(
function () {
if (!$('#cluetip').data('hovered')) {
$('#cluetip').removeData('hovered');
$(document).trigger('hideCluetip');
}
}, 100
);
});
});
The .live() would have been a nice touch here, but it doesn't support
blur events (yet).
Thanks for the nudge in the right direction.

[jQuery] Re: JQuery AJAX
Your URL is the culprit. And the way you are passing data.
Doing http://myserver.com/index.gif?id=1event=e is a GET request - the
params are on URl directly. If you want this data to appear in the POST
then you need to pass them right:
$.ajax({
async: false,
type: 'POST',
url: 'myserver.com/index.gif',
data: 'id=1event=e',
cache: false,
timeout: 0
});
This *should* take care of the OPTIONS thing (I don't know anymore
details on that at the moment..)
Some observations. Did you really mean to do a synchronous call?
Synchronous calls are blocking - they stop further processing until a
result is returned. If that result never returns, you've hung your
code. This is what the timeout attempts to handle. There IS a time and
place for synchronous calls, but with what you've given us so far I
don't think this is one of them. To make it asynchronous (which is what
the first A in Ajax means), you'd change your code like this:
$.ajax({
type: 'POST',
url: 'myserver.com/index.gif',
data: 'id=1event=e',
cache: false,
});
Next, you are setting cache to false - I'm assuming because you really
want the server to process each request. What I've done in the past is
to just attach a random number to the URL.
url: 'myserver.com/index.gif?r=' + Math.random()
this works well enough for my needs, though I'm not sure if this is a
best practice.
Next, your url parameter points to 'myserver.com/index.gif'. $.ajax
cannot do cross domain requests (unless you use jsonp, which is a little
beyond this discussion...). The URL should be a relative path to a file
from your current page. Also, why are you requesting index.gif? Do you
have serverside configs that redirect index.gif? Why not just call
mypage.php instead? Remember that an Ajax call is a REQUEST of a
resource, and that resource can return whatever. I suspect you are
converting some old school code where the request for a gif file was a
precursor to modern Ajax, but could be wrong.
Finally, Your request will return a response of some type. You should
be handling that response in the success and/or error properties. Then
again, they are not required. But what happens if something unexpected
happens? Does your app fail gracefully?
This should get you pointed in the right direction. I suspect you may
have problems with your event parameter (it appears it should be an
object, not the letter 'e'...), but that is relatively minor.
Hope this helps.

[jQuery] ClueTip focus/blur trouble
Hi Gang.
I'm working with ClueTip and have run into some oddities.
In particular, I want to show ClueTip when a textbox receives focus.
The source shows me that I can use activation:'focus' for this and that
will result in the cluetip showing on focus and disappearing on blur.
Showing the cluetip is working fine, blurring is not.
The code I have is this:
$this.cluetip({
activation: 'focus',
local: true,
showTitle: false,
sticky: true,
mouseOutClose: true,
arrows: true,
closeText: strongX/strong,
closePosition: title
}).focus( function (){
$(opts.source).children().removeClass(opts.hover); });
The .focus() method that I have here is simply resetting the classes on
the items the user may interact with.
I'm using ClueTip to provide a rapid selection tool - similar to a drop
down list, but without the drop down list UI. (large number of options,
needing HTML for formatting, etc.) The idea is that when the cursor
arrives at the textbox, the cluetip shows and the user can use either
the mouse to click an item, or the up/down keys and enter to do the
same. Where I am running into problems is with the click selection. If
I add a blur handler to the above code:
.blur( function () { $(document).trigger('hideCluetip'); })
then things work well for keyboard selection and blurring, but if I
click instead, the click event never happens. Because, clicking on the
cluetip triggers the blur of the textbox which closes the cluetip before
the click can be handled. I suspect this may be partly why the onblur
isn't working within ClueTip as well - the logistics seem rather complex...
So I'm looking for suggestions on how to get this running properly. OR
for a plugin that provides similar functionality already. Thanks for
any feedback.

[jQuery] superfish navbar - how do I center the whole bar?
I'm using a navbar with superfish. I simply put my menu list inside a
wrapper so the markup looks like this:
div class=navbar-wrapper
ul class=sf-menu sf-navbar
li.../li
li.../li
li.../li
/ul
/div
now I want to make the navbar-wrapper 100% of width and the navbar to
be centered in it, I thought it should be simple just do the following
css trick
div.navbar-wrapper{ width:100%; text-align:center; }
However this didn't work, the supersish menu just didn't get
centered.
How can I fix this? Thanks.
[jQuery] Re: superfish navbar - how do I center the whole bar?
If you have markup as indicated below, then you have invalid markup,
which will cause problems.
A UL element can't contain a div - it has to contain li's, which in turn
can contain a div. I would expect that structure to fail.
Removing the div immediately after the UL, will clean things up.
Now, for centering, you may have to wrap the whole thing in a separate
div and then use the CSS tricks to center THAT div - auto margins,
text-align, etc.
er. just read your request a little more. Try this:
div class=navbar-wrapper
div class=centerMe
ul class=sf-menu sf-navbar
li.../li
li.../li
li.../li
/ul
/div
/div
Apply the centering tricks to div.centerMe.
Disclaimer - I just pulled an all nighter, so I need to freely suggest
that my advice at this point may be questionable... :)

that's kinda rough, but should get the point across. The results you
get back from the ajax call can be whatever you want - a new HTML
definition of the select element, a json array of objects, a simple
array of text values (as hinted at in the sample code), or even xml.
Whatever you pick for the results format dictates what you have to do
with the results to get it into your select list.
The flexibility and diversity of the approaches here are probably why
there is no (known) plugin. Yet the code is simple enough to slap
together in less than 5 minutes.

[jQuery] Re: Ajax populating select box based on radio selected
that is a different issue than the ajax thing. but, it's also a common

$(input[name='myradio']:checked).val()
That should do it. Get the value of the checked radio option... I
changed it to not use an ID, cuz chances are you are you are using a
name and not an ID...
Failing that, you could extend things a little and loop over each of the
radios:
$(input[name='myradio']).each( function () {
if ($(this).attr(checked) == true) {
radioValue = $(this).val();
//do something with the value
// ...
//no need to loop to the next item,
//so return false to end the .each()
return false;
}
});
The first approach is preferable, I'd think - less looping involved.
But this second approach shows an expanded way to do the same thing,
which is sometimes needed when doing something a little more non-simple.

[jQuery] Problems with elements shifting when scripts are activated in IE8 (jscrollpane script)
Hi there, I'm fumbling through here so I apologize in advance for being such a newby to javascripts and jquery. I spent the entire day yesterday getting jscrollpane to work on a site I've been working on and was SO excited to see that it was working beautifully in firefox this morning after some editing of the code and figuring a few things out. Unfortunately in IE8 something is causing all of my elements to shift up way above where they should be, including the sidebar navigation which should have nothing to do with the jscrollpane script. The only reason I'm thinking it must have something to do with the script is that when I open in IE it looks fine (although with the ugly browser scrollbar) until I activate the script in the script/ activex pop up bar along the top of the screen. As soon as I click to allow the scripts it shifts all of my content up. I've uploaded the site to a temporary area of my own site here: http://www.auntiepea.com/ew/OldFarm/index.html The same thing happens on one of the other pages that I thought I had finished here: http://www.auntiepea.com/ew/OldFarm/services.html I would SO love to be able to use this script but I think I've hit my level of javascript abilities here. Any advice would be GREATLY appreciated. I posted this to the jscrollpane also but thought I'd post here as well since it was mentioned on the jscrollpane page that I may get a faster response on this discussion board and I'd really love to figure this out today if possible. Thanks so much in advance!
[jQuery] Re: Problems with elements shifting when scripts are activated in IE8 (jscrollpane script)
Thanks so much BaBna. I think you're right about it not having anything to do with the javascript itself. I probably should be asking this in a general web design forum except for that I've never had issues with this shifting (at least not nearly to this degree) on sites that haven't included the javascript area so I'm hoping maybe someone can take a peek at the code and see if something obvious jumps out that I should be doing differently. Could it be the placement of the scripts? Or is there an issue with using an editable region of a template to call on the script. I'm hoping not the latter because I'll have a number of pages within the site that I'd like to use the scrolling script and would rather not have to rebuild the navigation area for each page. After rebuilding the entire template and index to try and clean up the issues, hoping this time things would line up properly in IE the way they do in firefox now the scrollpane/main content area has shifted below the area where it should be. I was hoping maybe including a header and footer (although basically empty boxes) that I could contain that main content area in the correct area. No such luck. :( I would be eternally grateful for further direction on which area it is that's causing my IE issues.

[jQuery] Re: keepp getting NaN vlue
further to that, you can do
var distance = parseInt($(#distance.val(), 10);
Using the radix (the second parameter - 10 in this case), forces the
specific conversion you'd like. When dealing with dates at least,
leaving out the radix can sometimes result in abnormal behavior that is
VERY hard to troubleshoot.
Oh, if the number is not an integer, use parseFloat() instead of
parseInt(). (er, sry if this is TOOO basic.. :) )

[jQuery] Re: Page goes up when I click the link
Not familiar with the BlockUI plugin. But, do you have a .click() event somewhere related to that link? If so, return false from the event handler. Setting href=# means a named anchor. # by itself is top of the page. So, if the anchor tag's normal click handler is executed, you'll be returning to the top of the page. You need to stop the normal handler - which is usually done in jQuery by returning false from and event handler function.

[jQuery] Re: Page goes up when I click the link
judging from that snippet, I don't think jQuery or BlockUI is the problem.
Using onClick is old school and should be avoided these days. It mixes
functionality with data/presentation when these things should be kept
separate. (just like CSS should be kept in it's own file rather than
inline, JS should be the same...) The phrase that describes this is
unobtrusive javascript.
You can try changing the onclick= in both samples to
onClick=(); return false; - where the () is the existing
functions (add a return false; at the end). But I think you probably
need to look into native JS methods to stop propagation.
Is this inherited code? Or generated by Dreamweaver? Eitherway, the
code looks reminiscent of DW to me. Both those functions should
probably make better use of jQuery, but methinks that is a separate
issue.. :)

[jQuery] Re: how can I treat a string as JSON?
instead of using $.getJSON(), maybe use $.ajax() directly?
Something like this:
$.ajax({
url: 'some/url.php',
data: 'id=' + $(#id).val(),
type: 'post',
dataType: 'json',
success: function (results) {
console.log(results);
}
});
The magic here is the dataType option. It tells $.ajax that it is
expecting a JSON object and does what it needs to to convert the results
to an object (if possible). The results variable is just the object
passed to the success callback function - name it whatever makes sense
to you. But once inside the success function, you *should* be dealing
with an object, not a string.
I find that in most cases $.ajax() is much clearer and causes less grief
for me than using the other Ajax type functions (.load(), .getScript(),
.getJSON(), .get(), .post(), etc.). I could be wrong, but I think these
are all just wrappers to $.ajax() anyways. I do use some of these
convenience functions, but the moment I need to start worrying about
callbacks, or what data I'm passing, $.ajax() makes life clear and
simple for me.

The string returned is already a json object, I just need jQuery to be

Any suggestions?

[jQuery] Re: Anything wrong with this ajax syntax?
Your URL indicates you are returning json (returnType=json). But, you
do not specify a dataType for the $.ajax() call. So, your response
variable is plain text, I think.
Two things to try:
1) put dataType: json, before the success line.
2) first line of the success function, do something like
console.log(response); and see what you get. If it is plain text, you
will see the text. if it is JSON, you should get an object or array
shown (firebug will color code these for you. um.. you ARE using
Firebug aren't you? lol )

Is there something missing that would keep it from functioning?
This ajax function only serves to cause a ColdFusion function to create
HTML that is then loaded as specified in the code.
However, the success part of the function is not executed.
No errors or anything…it’s as if the ajax function just doesn’t work at all.
If I put “alert(‘Inside function’); “ just after the first line of the
function and
before the $.ajax line below, the alert fires properly. If I add an alert
in the response section in the first line of the “if” section, the alert
doesn’t fire.
Again, no errors from my server-side code or for the jQuery.
So, the question is whether or not the $.ajax function will work as coded,
or are other parameters needed? (I tried ‘post’ for type, as well…)
Here’s the $.ajax function:
script type=”text/javascript”
function buildLoginDialog() {
$.ajax = ({ cache: false,
type: 'get',
url:
'components/login.cfc?method=mBuildLoginDialogreturnType=json',
success: function(response) {

{ var loginDialogHTML =
'components/loginDialogHTML.cfm?' + new Date().getTime();
$('.loginDialog').load(loginDialogHTML);
login(); }
else { alert('Login Dialog Build

}
});
}

[jQuery] Re: Sloppy Documentation of Ajax Methods
ALL the functions (load, get, post, etc) are wrappers for the $.ajax() function. I only use $.ajax() now and tweak it to meet my needs... Makes for less confusion. Ajax by default will only load files that are in the same domain as the calling page. This is a browser security feature. (Use $.ajax() and jsonp to work around that.) So the getScript() function will follow this limitation as well if it is calling the new script via Ajax. My thoughts. Shawn rickoshay wrote: Here are the descriptions for the Ajax methods: load -- Loads HTML from a remote file ... ajax -- Load a remote page ... get -- Load a remote page... getScript -- Load and execute a local javascript file... post -- Load a remote page... So, if we want arbitrary HTML we have to use load, but if we want a whole page (where is that defined?) we have to use ajax, get or post? The execute script function (called getScript for some reason) only works with local files? I believe it will work with any URI (local or remote) returning JavaScript (assuming same origin policy of course), and whether it came from a file isn't known to the caller. These functions should describe the type of HTTP request they make, and skip references to pages and files.

h1Height = $('this'+'h1').height();
What went wrong?
[jQuery] Re: simple JSON parse problem!!!
As mentioned in another reply, theObject is an object.
So, building a string with
( + theObject + );
will not give you what you'd expect. If that were to work at all you'd
likely end up with a string of ([Object]) - not what you want.
If you really must do the eval(), then it should be something like
var json = eval( '{ key : value }' );
But, eval() is evil and should be avoided wherever possible. Mostly
because it is mis-used, introduces various issues, and is known to be an
expensive call in terms of processing speeds. It *is* the right tool in
some cases though...
In your code, I'd recommend doing as MorningZ mentioned:
var theObject = { key: value};
alert(theObject.key);

[jQuery] Re: getting the value of list box in jquery
First, this is a mailing list. Not an IRC channel or Instant Messenger.
This means replies can take hours or even days sometimes. Patience is
the keyword here. If you need help with an issue that urgently, try the
##Javascript channel on IRC. The message I am replying to is
timestamped 12:56am. If I kept normal hours, I would not have even seen
your message for another few hours yet.
As for your question. the .val() will return the current value of the
form element. A multi-select list *may* return all the selected
elements, but that is not my experience in the few times I've tried this.
In the case of a multi-select list, I find it better to fall back to
some old school techniques and remember that the selected property
will be set to true on each of the selected options. So, I do something
like this:
var selectedArray = [];
$(#right option).attr(selected, true).each( function () {
selectedArray.push(this.val());
});
alert(selectedArray); - should result in the comma delimited string you
are looking for. IF and ONLY if there are selected items.
The gurus here will tell you my approach is probably overly long, but
it's worked for me. Your mileage may vary. Tweak it as needed.

You would have more luck. In fact I'm willing to bet you'd be able to

[jQuery] Re: Big problem with Jquery
It's not a problem at all. I ran into this at one point myself. The problem that there are multiple plugins doing the same thing and the uncertainty of which was the right one for me. It turns out this is just part of the learning phase, I think. As you start seriously looking at these similar plugins, you start to notice differences - sometimes blindingly obvious, sometimes very subtle. These differences is what make or break the suitability of the plugin for your needs. The bonus is that because there are similar and sometimes competing plugins, they ALL get better (or get left behind...). But, there is no way any one plugin could ever be suitable for every situation they may be used in. Coding is not a cookie-cutter type environment. Sure there are some things that are incredibly common and have a number of quick-fix options. But almost always these then need to be tweaked to fit anyways - sometimes substantially. The better solutions - as determined by the community, and the active involvement of the authors (thereby gaining respect, trust, karma, etc) - tend to become recognized and/or adopted into the core set of plugins. Some of these have been absorbed into the UI project, and I suspect more to follow (autocomplete and cluetip anyone? :) ) My final take on this... Either you find a plugin that meets all your needs, or you have to write one yourself. Each coder has to weigh the time/cost factors and make a decision for their environment. There is no one answer to rule them all. My thoughts. Shawn zweb wrote: I really like jquery but I found one big issue with Jquery.

[jQuery] Re: How to print json data, key and value
Native JS is capable of this sort of thing.
For instance:
var obj = { p1: v1, p2: v2 };
for (p in obj) {
document.write( p + : + obj[p] + br );
}
This would output:
p1 : v1
p2 : v2
Using the for..in loop structure, you can iterate over each of the
properties of a given object. In this case, p contains the name of
the current property, and by doing obj[p], we treat obj as a hash
object and get the value of the property in question. The loop then
moves on to the next property.
(disclaimer - the document.write() line is for sample purposes only, I'm
assuming you'll using something more appropriate)
This will work with ANY object (assuming my memory isn't to far
gone), but will not go into the tree structure. If a propertie is
another object, or array, then it's value would be displayed as
[object].
HTH And I hope this is what you were after.

[jQuery] Re: [Autocomplete] - Doesn't always work
I don't see anything tooo odd here. Here's what I would suggest though:
1. Call the autocomplete function a few times manually. Put the URL to
it in the browser's address bar and load the page a few times (you'll
need to switch your code to use $_GET though). Try to mix up the speed
of reloads, the data being passed, etc. IF you see any blank pages,
then you know the server side code is where the problem is at. But if
you always see output, continue debugging
2. Temporarily remove the .result() method just to ensure that is not
causing confusion somewhere. Commenting it out should be good enough.
3. Make sure you are using the most recent stable version of the plugin.
4. In your PHP code, where you are checking for no 'q' value and just
exit the function replace that return with something like
echo no criteria|0;
return;
Just to see if this condition is the problem area. Also, I'd probably
change the condition to be if (empty($q)) - which is a slightly
better check. That's a style thing though, so up to you
Now, with that out of the way... Your PHP code seems odd to me. Why
pull back ALL clients and then do a string comparison to sort out what
to show or not? It is MUCH faster/more efficient to let the database do
that filtering for you. Do you have control of the Client class? If
so, can you add a search method that takes the 'q' value as a criteria
for the name? But, the code as is *should* run, so take my comments as
constructive observations... :)

[jQuery] Re: tutorial
Any time you see something like
$(a).addClass(test);
You can assume this is JavaScript. In particular, this is JS that makes
use of the jQuery library. JavaScript can only appear in certain places
- either in an included .js library (via script type=text/javascript
src=someLibrary.js/script), or within script tags.
Where jQuery is concerned, the $() method is not available until after
the jQuery library has been included. So make sure you include the
library BEFORE doing anything that makes use of jQuery.
In addition though, you often don't want the jQuery code executed until
the page is done loading. In this case, if the addClass method is
called before the HTML is rendered, then nothing will happen because the
$(a) would return nothing. In this case you want to make sure your
command is put inside the .ready() method. For example:
script type=text/javascript
$(document).ready( function () {
$(a).addClass(test);
});
/script
I haven't looked at the tutorial in years, but hopefully this is enough
to help figure out what you need.
I might suggest though to maybe nail down the HTML know-how, and read up
on basic JS. Both will help make this all make sense. As is you might
be taking on too much all at once and overwhelming or confusing yourself
- but that's how I learn too, so whichever works best for you.
BTW, Dreamweaver isn't a bad tool, but if you are working at this level,
put Dreamweaver into Code View, and don't use the Design View at all.
It might take a bit more to learn to start with, but you need to know
how to do everything by hand eventually (i.e. no graphical tool to write
code)... may as well start now. My thoughts though.

[jQuery] Re: json syntax question (ticket vs unticked names)
This all depends on where you are generating and using the json string.
Doing
{ key : value }
and then using that code immediately on the same page, typically works fine.
However, if you ever need to pass your json string to/from a server,
you'll find that this shortcut fails quite often.
For instance, using this shortcut to request information via $.ajax(),
often gives an odd error. While the request has a 200 status (meaning
the request succeeded without error), the error handler function (if
specified) would trigger - even though it appears the json is correct.
(disclaimer - I haven't done this since 1.2.x days, so don't know if
it's still the case)
To avoid these errors, use the standard and do
{ key : value }
especially when passing json via an http request (i.e to/from a server).
You'll have fewer problems in the long run.
My thoughts.

[jQuery] Re: json syntax question (ticket vs unticked names)
This isn't the same thing. Consider the following code:
var json1 = { jack: jack jackson };
var json2 = '{ sara: sara jones }';
In this case, json1 becomes a javascript object in memory. json2 is a
string that just so happens to look like a javascript object.
In the first case, this is valid because JS handles things properly.
This means you can use quotes or not for the property name - both work.
(unless you have spaces or other special characters in the property name).
In the second case, the string will not get converted to a javascript
object reliably in all cases. Because it is not a standard json string.
Perhaps I mis-understood the original question, but I thought we were
talking about instances where we were defining strings, in which case
quoting is healthier.
I personally only use the quoted property names when I am building json
strings - whether server side, or client side. But if I just need to
define an object client side, I don't usually bother.
So, I guess the distinction is what your target data type is - string or
object. With string, always quote. With object, it's optional.
My thoughts.

Try to jslint this fragment:

Unquoting alice makes no difference; doing the same for jack johnson

Then, in order to pre-emptively avoid such problems, my advice is to

[jQuery] Re: encode data in AJAX post?
The data parameter expects key=value type definitions just like typical
URLs. So if you have simple data you might do
$.ajax({
// ...
data: item1=1item2=2,
// ...
});
And build up that string however you need to.
If your data is in a form, you can use .serialize() or .serializeArray()
to do this quicker.
i.e.
$.ajax({
// ...
data: $(#myForm).serialize(),
// ...
});
If you have more complex data, but still relatively simple (i.e. would
fit a simple key=value situation where value is not another complex
object), then you can do something like:
var myData = {
name: $(#name).val(),
address: $(#address).val()
}
$.ajax({
$.ajax({
// ...
data: myData,
// ...
});
The $.ajax() method will convert your object to an appropriate string.
If you need more complex data - like say an array of objects, then your
best bet (IMO) is to create a custom JSON string to pass to your server.
// multiline for readability
var myJson = '{ [
{ name: ' + $(#name1).val() + ',
address: ' + $(#address1).val() + '
},
{ name: ' + $(#name2).val() + ',
address: ' + $(#address2).val() + '
}
]};
$.ajax({
// ...
data: json= + myJson,
// ...
});
While the $.ajax() method will handle a simple object nicely, it fails
when you have more complex objects - in my experience... I end up
getting an array of [object Object] strings, rather than the objects
themselves. So I end up having to create my own JSON string, or using
the array method of passing elements with the same name
(i.e. input name=person[] ), which I find to be hit and miss for
back end language support. PHP works fine, but ColdFusion doesn't like
it (at least not when I tried). So the JSON approach is cleaner in
that it works better with all back end servers - they just need to
decode the json string to an object and you can use it there. (I'm
actually hoping someone can tell me a better way to do this).
For the JSON approach, if it is a one off type thing, I'd say just code
the string manually. If you are doing this over and over, grab the JSON
libraries and let IT build your string for you. It is up to you to
decide if you want/need the extra libraries loaded loaded though
Hope that helps.

[jQuery] Re: web site configuration
If you do not know coding/javascript/DOM that well, I would suggest
sticking with one page per change.
But, if you want to dive in...
Set up a div with an ID, and then use the load method to change it in JS
when needed.
i.e. (this has not been tested in any way)
div id=myslides/div
a href=# id=previousSlidePrevious/a
a href=# id=nextSlideNext/a
script type=text/javascript
$(document).ready( function () {
$(#nextSlide).click(function () {
$(#myslides).load(myslide.htm);
});
});
/script
With a little logic in there you can easily decide what slide you want.
Then just put each of the slide content (image, html, etc) into it's
own file and call that in the .load() function.
This approach can be simple, or it can get a little complex - especially
if your loaded page includes other JavaScript to use. But this is a
well known type of issue that has been dealt with many times

[jQuery] Re: How save is Jquery with JSON
Three options:
jsonp - allows ajax type requests to other domains
iframes - set the src attribute on an iframe to the remote page, use JS
to extract the info you need from that frame
server side - do an http request via your server side code, extract what
you need there, and make it available to your page as needed.
There may be more options for getting data from remote URLs, but these
are what I have commonly seen. The server side approach is probably the
easiest and/or better performing option.
My thoughts.

[jQuery] Re: getting to a variable in the parent frame - stumped
By declaring var module inside the function, that variable only exists
inside the function. If you need access to that variable outside the
function, you need to either return it from the function (i.e. return
module; ) or declare the variable in the global scope. Something like this:
script
var module = null;
$(function () {
module = { . . . }; // reset the global variable to some value
});
/script
Now you can refer to that module variable from inside your iframe with
console.log( window.parent.module );
(Assuming I am remembering my terms right - it's been a long while since
I needed to do this...) In that statement, window refers to the
current window - aka the frame. parent refers to the element that
contains the window if one exists (refers to itself if it IS the top).
Global variables (and functions) are properties of the window - not the
document.
Then only part I'm not sure on is the use of the $() function in your
code. I'm not sure if jQuery places the defined function on the global
stack or not. If so, then you shouldn't even need the first part
Hope that helps.

2.

[jQuery] Covering multiple elements with a single function, but passing a variable?
Hi. I'm stuck trying to figure out the jQuery way to code this
functionality I have in my project.
Below is a stripped down example of what I'm trying to do. When I
click the Add Item link below any list, I want to just append a new
element to the end of that list. What I do now is just use an onclick
element for each anchor tag, and call addItem and pass the specific
list_id for that list. The function then dynamically locates that
specific list and appends a new item.
What I have here works (excuse any typos, I'm writing from memory),
but I'd like to make it cleaner by getting rid of the onclick calls
and just having jQuery bind a function to the additem class. I just
can't figure out how to pull in the list_id variable in each case.
Any ideas?
...
function addItem(list_id) {
$('#list_'+list_id+' ul').append('lidata/li');
return false;
}
...
ul id=list_1
lidata/li
lidata/li
/ul
a class=additem href=# onclick=addItem(1);return false;Add
Item/a
ul id=list_2
lidata/li
lidata/li
/ul
a class=additem href=# onclick=addItem(2);return false;Add

Just to put an answer to this, in case someone else runs into it... The problem was a PHP issue. The problem line was $data = json_decode($_GET[p]); That line is perfectly fine, and the p var does have data. However the quotes in the string were automatically escaped. So the line needed to be changed to read $data = json_decoe(stripslashes($_GET[p)); At which point it worked as expected.

[jQuery] Re: Instantiating multiple plugin instances on the same page
Depends how your plugin is set up.
If you didn't implement the chaining techniques, then chances are you
only have one instance. But if you did implement chaining, you *should*
have multiple instances.
Do you have something like this line in your plugin?
return $(this).each( function () {
// plugin code goes here
});
If you can post your code, we can help more. OR, you can go to the

[jQuery] Re: A real modal window... is it possible?
This is a coding approach issue, rather than a modal window issue. To me at least. When I needed behavior like this, I wrote my code in such a way that a function was called that set up the environment and then opened the modal window. Now that the modal window is open, I know that nothing else should be receiving events, so there is no code to execute other than for the modal stuff specifically. Now when the window is closed, I call the appropriate function (cancel, save, etc) and continue processing from there. In this way, my processing has stopped until the Modal window triggers the next part of processing. Of course, this is not the answer for all cases. But, working in an asynchronous and event driven environment, this tends to work well enough. To acheive what you are asking for would be possible if you were working in a synchronous or procedural environment. But that doesn't describe a web page per se My thoughts... Shawn Richard D. Worth wrote: What I mean to say is, a modal isn't about stopping flow of code. It's about restricting interaction to a certain set of elements, until the interaction is complete. So it allows interaction with elements in that modal (requiring code flow - remember javascript is single-threaded), preventing interaction with all others, until it's closed. If you're wanting to call a modal like a function and have it return a value (think confirmation dialog), it won't work to block like that. An alternative pattern is to provide a callback function that will resume execution after the modal is closed. - Richard On Fri, Nov 14, 2008 at 4:48 PM, Eric Martin [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] wrote: I guess it depends on what you mean by flow of code must STOP.

[jQuery] Re: Event Capture Architecture
For ease of coding, a separate bind method for each element is pretty
straight forward. However when you are dealing with a large number of
elements, and your processing needs to look at those large number of
elements, then performance can get to be a problem.
For instance
$(.myclass).click( function () { ... });
This looks innocent enough, but if you have hundreds, or even thousands
of elements on the page, then finding all the .myclass elements can
take a while. Of course, narrowing down the selector helps -
div.myclass for instance.
I found this problem to be especially visible when dealing with a very
dynamic page. (mine was a calendar type application where LOTS of info
via Ajax that would result in updating the calendar and needing to
reapply handlers).
In cases like this, you'll probably be better off applying the click
handler to a container element if possible, then using the event.target
element to look at the element throwing the event.
Oh, and if you need more data for processing than just the ID, don't
forget about the jQuery.data() method

Need a little more detail. How are you selecting a node?
If I assume for a moment you have a class called myClass on the

clicking on them, then you can get the ID like this:
$(.myClass).click( function () {
var theID = $(this).attr(id);
// ... do something with the id

You can get ANY attribute using the .attr() method.

[jQuery] Re: reading values from HTML tables
I *think* the following will get you started:
$(#veh_odometer).children(tr).each( function () {
//'this' refers to the current tr
var address = $(td:eq(2), this).text();
console.log(VALUE: + address);
// note: console.log works in Firefox.
// Substitue an alert if desired
// . . . Other processing here . . .
});
Two points here though:
- The $(#veh_odometer).children(tr) bit can be done in a few different
ways. But this should work (unless the the tbody element is needed too...).
For instance you can say $(#veh_odometer tbody tr).each() for
effectively the same results experiement for the method that works best
for you.
- the var address line. We are using a context reference here - we are
saying give me the third TD in the context of the current row (this). Again,
more than one way to do this... $(this).children(td:eq(2)) would do the
same ( I think ).
Anyways, hope that helps.

Two points here though:
- The $(#veh_odometer).children(tr) bit can be done in a few different
ways. But this should work (unless the the tbody element is needed
too...). For instance you can say $(#veh_odometer tbody tr).each()
for effectively the same results experiement for the method that works
best for you.
- the var address line. We are using a context reference here - we are
saying give me the third TD in the context of the current row (this).
Again, more than one way to do this... $(this).children(td:eq(2)) would
do the same ( I think ).
Anyways, hope that helps.

[jQuery] Re: Howto Question
Or, don't use hover. If you make the users click the link instead of just
hovering over the link, then you basically have a toggle. (there is a
.toggle() method as well for this sort of thing...)
Or you can use a timer. When the hover ends, start a timer. Then clear/reset
that timer if the mouse moves over the revealed area or the original link. If
the timer is allowed to end, then do the usual fade() bit. The length of time
for this is up to you... 500 ms, 1 sec, etc... The hoverIntent plugin might
help out with this.
Some thoughts.

overlaying the image, containing a number of links / text. However now
if i hover over #myContainer to click on one of the links the
#myContainer fades out and i can't click on the links. I guess i could
work round this by doing this:

Build your HTML. Use CSS to position things where you want. For
example, a DIV with an absolute position. Then when you are happy with
the positionin/layout, set the container to display: none. Give that div
(or container) an ID. Now you can do something like this:
$(document).ready( function () {
$(#myLink).hover(
function () { $(#myContainer).fadeIn(); },
function () { $(#myContainer).fadeOut(); }
);
});
I may have the .hover event wrong (docs aren't loading for me right this

the .toggle() method as well - up to you.
Btw, simple fading requires no additional plugins.

[jQuery] [autocomplete] Some random questions
1. Is there any difference between Jorn's autocomplete from his webpage (http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/) and the one included in jQuery.ui 1.6rc2 ? I can see the copyright info is the same, but don't see a version number for the autocomplete element... 2. Using the jquery.ui version of autocomplete, what steps are needed to make the autocomplete work properly in a modal dialog via jquery.ui's dialog? (my initial tests show the code working, but the result area is not showing - I'm using a theme from the themeroller if that matters). I'm using a local data set for now. 3. It's been about a year since I last looked at autocomplete. Anything new that I should be aware off? (I was using Jorn's plugin back then as well...) Thanks for any info. Shawn
[jQuery] Re: [autocomplete] Some random questions
Thanks Jorn.
I can say that I've tested the integration of autocomplete and dialog now. :)
So far so good.
What I was missing was the change from .autocomplete(url/data, options)
to .autocomplete({url: , data:, etc.}). Once I found that the plugin
worked fine. I have not seen any errors per se. However I did notice
the .result() is not binding (or perhaps I'm using it wrong... was planning
on looking into that today).
But, if autocomplete will not be included until 1.7, then I should probably
just use your plugin, rather than UI's version.
Thanks for the info.

[jQuery] jQuery.ui modal dialog with themeroller theme?
I'm finding that if I use any of the themes generated by the ui themeroller, I cannot use them with a modal dialog. The form elements cannot receive focus.. But if I switch to a non-modal dialog everything works. Anyone know any way around this? I really do need modal dialogs, but do not understand the CSS well enough to role my own (at the moment..). Thanks. Shawn
[jQuery] Re: (Resolved) jQuery.ui modal dialog with themeroller theme?
Figured it out. Accidently. :)
If the ui-dialog class is manually assigned to the dialog container before
opening the modal dialog, the text boxes do not work right. However, if the
class is not manually assigned and just treated normally, the text boxes work
fine.
I.e. the following code fails:
$(#dialogContainer).remove();
var dc = $('div id=dialogContainer class=ui-dialogcontent/div');
$(body).append(dc);
$(#dialogContainer).dialog({
title : Organization,
modal: true,
width: 650,
height: 350,
overlay: { opacity: 0.5, background: black },
});
But changing the var dc= line to
var dc = $('div id=dialogContainercontent/div');
and the above code works great. (assuming your content has some text boxes
in it of course...)
Funny how sometimes forgetting to add a class in can lead to such
discoveries.. :) Hope this helps someone out.
Shawn.
Odd. in my same project, with similar code, The modal dialogs work fine.

[jQuery] Re: [TUTORIAL] Create a professional interface for your web applications using jQuery
Not a bad tutorial. !
But... :)
In your code you are doing things like
# var windowHeight = document.documentElement.clientHeight;
# var menuHeight = document.getElementById(menu).clientHeight;
You can use jQuery here too:
var windowHeight = $(window).height();
var menuHeight = $(#menu).height();
at line 158 you have the following:
# var liList = $(#lateralPanel li).get();
# for (var i = 0, item; item = liList[i]; i++) {
# if(item.innerHTML == $(this).text())
# item.className = active;
# else
# item.className = ;
# }
I believe this can be replaced with:
$(#lateralPanel li).removeClass(active);
$(this).addClass(active);
- that will remove the active class from all the list items, then add it to
the target element that triggered the click event (the function that
surrounds the snippet above).
Also, you have code in there that handles browser differences. jQuery handles
most of this for you. For instance:
$(#myObj).height(100);
handles the differences between most browsers. Which makes your code even
easier to read.
Otherwise not a bad start. Keep em coming. :)

[jQuery] Re: jquery.ui theme issue (via themeroller)
More info The dialog works fine, unless it is modal. The overlay gets a z-index of 1001. And seems to always be 1 more than the highest z-index on the page. Themeroller does not include any classes for the overlay, so this seems to be a conflict between the themeroller classes and the default library based styles. (because Flora works fine with those same styles...) If it helps any, I'm running FF3 on 64bit Kubuntu.

[jQuery] Re: How to queue up ajax requests?
partner56290674 wrote: secondly, i still am confused to why u think jQuery should not offer this support because you believe this is bad. Remember, the idea of I think it is inappropriate because you are describing an application specific issue. Not all applications will have the same needs. The requirement is not general enough (IMO) to be made part of the jQuery framework. Your needs and my needs are similar, but still very different. Do you try to handle ALL possibilities in the framework, or provide the tools for the developers to solve their own needs? Additionally, you *could* set up jQuery to monitor the page for change requests, but that is just one approach. Typically web pages are event driven, and those events trigger ajax calls if/when needed. You mentioned the autocomplete - this is a great example here. If a user starts typing, do you send an ajax request for EVERY keystroke, or do you introduce a slight delay to find when the user has paused in typing, and THEN send the ajax request with the changed text? (note that no queue is needed at all) That is a judgment call needed by the application developer. Most autocomplete solutions introduce the delay, but there may be legitimate times when this is not desired. (simple select instead of autocomplete maybe?) It still comes down to the individual developer knows best what they need. The framework should only provide the generic tools to help the developer solve those needs - NOT try to solve all developers needs in one package. But this is all just opinion. I'll leave those decisions to John Resig and the rest of the core developers... My random thoughts Shawn
[jQuery] Re: How to queue up ajax requests?
the flooding the server with calls is a non argument. If you don't want to do that, then you need to redesign your server side code to accept a single request to give you all the data you need. One call, one response then. But that's a server issue. And there are performance/modularity issues with that approach (depending on scale/volume). Any other way means the client making multiple requests from the server. As for displaying them as they come back to the user, nope. Only once ALL the requests are completed is the further processing done. But this meets MY specific needs. I had a situation where I needed 3 distinct ajax calls, but needed the results of all 3 before I could render the output properly. My approach handles the possibility of the responses not being in order. As for queueing up ajax requests, doesn't that defeat the purpose of an asynchronous environment? Afterall, the end result of queuing up requests is a synchronous routine. Why not just load another page that does everything you need? Your use of the phrase queue may be accurate, but I think you are using it slightly differently than I interpreted it in this case. But, if we cannot clearly define what you are trying to do, then we cannot clearly tell you if it's in core jQuery, or in a plugin.. :) Shawn partner56290674 wrote: what your doing there Shawn is still flooding the server with ajax calls, and displaying them as they come back to the user. What happens if some requests come back out of order (eg. latency)? now if u switched it around .. that might be usable... so there's nothing built in to jQuery? Is anyone else queuing up their ajax requests?
[jQuery] Re: How to queue up ajax requests?
Your situation is clearer now. I would think though that the solution is a little simpler. Bear with me as I talk through this, but I haven't had the joys of working with google maps like this (yet)... So, user loads the page. Then user starts panning around. Rapidly. Instead of trying to show EVERYTHING that every pan would result in, wouldn't you only need to show the results from the ending location? If the user managed to pan over 5 screen widths in under a second, don't you only care about what would be visible when the panning is stopped? (I'm trying not to make any assumptions about your app, but.. :) ) So, if that is the case, maybe a short delay before you trigger the ajax routines to get your pins. Pseudo logic for that might be: pan start - clear old time out value (if any) - set new timeout timeout - get pin data for current area - render pin data And then if you set the timeout to something reasonable - maybe 500 ms?, then you end up sending much fewer ajax requests, and dealing with fewer pins as well. If needed, you can still combine this approach with the queue idea. But instead of queuing ajax requests, queue the areas that need to be retrieved on each pan, and then when the timeout fires pass that data to your server side code. Just a thought... and maybe easier to code than ajax queues. But I guess the answer you are looking for is no, jQuery does not have anything out of the box to do what you want. Nor should it, in my opinion.. :) There may be a plugin for this sort of thing, but I haven't seen one (yet). Shawn partner56290674 wrote: the flooding the server with calls is a non argument. If you don't want to do that, then you need to redesign your server side code to accept a single request to give you all the data you need Not true .. well at least I don't see it as that. I have no probs with multiple calls hitting the server at once. If you can't write scalable code, then that's your bad luck and out of scope of this discussion. This leads to this quote: As for queueing up ajax requests, doesn't that defeat the purpose of an asynchronous environment? Afterall, the end result of queuing up requests is a synchronous routine. Why not just load another page that does everything you need? and But, if we cannot clearly define what you are trying to do, then we cannot clearly tell you if it's in core jQuery, or in a plugin.. :) Also not true .. actually far from it .. and i'll use the example i want to do, to illustrate this. I'm doing some Ajax calls with my google maps, so when the map is panned, an ajax call hits our server to retrieve some data to show ON the map. Easy. Now, the problem lies when users pan-pan-pan-pan-pan .. ie. do lots of pans in quick succession. Now having 5, 6 or even 10 hits to our server is not a problem. It gets messy when the browser is trying to download lots of google map tiles AND then render hundreds of pins (our results from the ajax) .. especially if all the results are coming back async. So to help relieve the pressure on the client side, by having an ajax QUEUE client side, the results will only be rendered one at a time. By default, the browser will try to hit the server the with the max number of connections to the same domain (eg. Internet Explorer is defaulted to 2 connection, prior to IE8 i think). that's what i'm trying to do and why i believe it's important. It's also for scenario's with latency issues ... check this vid out (and ignore the fact that it's about script.aculo.us): http://www.phppatterns.com/stuff/latency.html does that make more sence? -me-
[jQuery] Plugin accessor method?
I've built myself a custom plugin that works nicely, but I have one
(maybe two) little sticking points
My plugin takes the form like this:
(function ($) {
$.fn.myPlugin = function (options) {
return this.each( function () {
$(this).data(myValue, some_value);
});
function show() {
alert($(this).data(myValue));
}
};
$.fn.myPlugin.getValue = function () {
return $(this).data(myValue);
}
})(jQuery);
I want to the implementing user to be able to ask for the specific value
with something like $(#myObj).getValue(); - or even
$(#myObj).myPlugin.getValue(); The getValue() method shown above is
not working - the this object is wrong. So, I'm looking for ways to
accomplish this.
Second, I want to be able to explitly set the value via
$(#myObj).setValue(new_value);
This set method would need to change the value stored via the .data()
function, AND call an internal method to display the new value (such as
the show() method shown above)...
I'm drawing blanks and dead ends in my efforts on these two points. Any
suggestions? (other than calling the .data() function directly - I may
be changing the storage method)
Thanks in advance.

[jQuery] Re: How to queue up ajax requests?
What I did was to build an object that would hold the results of each
ajax request. I added on a function that would check when all the
objects were populated, and then call the routine that would handle all
the data.
Something like this (note I'm NOT using the ajax_queue plugin):
var ajaxQueue = {
responses: [],
checkDone: function() {
//change the check value to match the number of expected responses
if (this.responses.length == 3) {
finishProcessing(this.responses);
}
}
}
//and then ajax calls something like this:
$.ajax({
url: somepage.php,
success: function (data) {
ajaxQueue.responses.push(data);
ajaxQueue.checkDone();
}
});
And then the finishProcessing() method does whatever is needed...
This got me past some significant performance issues from synchronous
ajax calls (one ajax request initiated the next, etc.). But, I'm sure
this is only one approach
