[jQuery] Re: aborting a $.getScript() request
If the script does not exist then the insertion of the script
element will fail (which is how cross domain getScript() works). So
you can't really test for a time out.
However you could set a flag in the success/callback function. After
the getScript() call you could use a setTimeout to test for that flag
after a certain time. If the flag isn't set then the load didn't work
or took too long.

[jQuery] Re: is that possible to go back on window unload event
You want the onbeforeunload event.
http://www.4guysfromrolla.com/demos/OnBeforeUnloadDemo1.htm
It's non-standard in that you can't actually use it like a normal
event. You'll need to use the old window.onbeforeunload = function()
{ ... } format, not the jQuery.bind(...) format.
Your event handler function actually has to return a string. The
browser will provide a popup which will ask the user whether they want
to leave the page, and include the text you return from your function.
It's an ugly hack but it's the only way you can do anything about a
user closing the window.

That will work but it has some rather unexpected consequences, the
biggest of which is that the entire browser will lock up (UI and all)
until the response comes back from the server (which could be a few
seconds). That's not a good thing to do to a user.

Restoring the input field's value is only one part of the problem.
There are a number of other attributes that might need to be restored.
Depending on how the backend code originally displays the form, a
field can start out enabled or disabled. It can start out with a
special class assignment. These attributes can dynamically change as
the form is used. Therefore resetting a field may involve more than
restoring the field's original value.
What I was hoping I could do was store an jQuery object that contained
all of the information about the field and somehow (magically) use
that to overwrite the current representation of that same field.
Am I dreaming?
Thinking of other ways to solve this problem, is there a way with
jQuery to get the full html of an input element? The .html() method
doesn't do it.

is also helps deal with memory leakage problems. So no, no global

The corruption of 'this', as we've explained, isn't a corruption.

To continue Karl's point, if you use jQuery the same way you would use
prototype then you'll be fighting it all the way. The prototype
solution squirrels away references to the DOM objects in the class and
then points event handlers back to the class. jQuery usually
encapsulates the data and events within the DOM element or a closure,
e.g.:
$(selector)
.data(options, {answer: 42})
.click(function(){

To sum this up - I want to create custom reordering / visibility toggling behaviour + independent class / plugin for storing the state of those operations and loading it up on the page load.
[jQuery] Re: Objects Methods as event handlers.
First a solution for you. Try this plugin:
http://plugins.jquery.com/project/bind
Now a note about the way jQuery is biased (which you can skip if you prefer).
jQuery is primarily focused on DOM elements. Everything else gets
attached to those elements. It's not a bad thing, it's just
different to what many expect. What I mean by this is if you instead
consider DOM elements to be views of internal objects then you'll
find your mindset clashing with the way jQuery is biased.
You've already come across the bias as you can see the bind() function
binds a function to a DOM element, and the this inside the handler
actually refers to the DOM element rather than some external object.

I've recently taken on a job where I have been required to use jQuery
instead of my usual framework of choice - prototype. I've handled the
transition well enough but one area of functionality has me befuddled
- using object methods to handle events. I've been working around the
problem but the workarounds are quite ugly.
An explanation. First I'll give the code as it would look in prototype
myClass = Class.create({
this.element: null,
this.initialize: function( element ) {
this.element = element;
element.observe('click',
this.onClick.bindAsEventListener(this));
},
this.onClick: function(e) {
// actions on click here.
}
});
Now I know how to build classes in javascript without prototype's
Class library. I also know how to use late binding and prototype
modifications to achieve what that library abstracts. The problem is
how am I supposed to replicate bindAsEventListener? I've tried...
myClass = function( element ) {
// element is an element somewhere in the dom that this class will
manage a behavior for.
// Assume for the purposes of this example that it's already
encapsulated in a jQuery object
this.element = element;
this.onClick = function() {
// on click actions.
}
this.element.bind('click', this.onClick );
}
If I run the code as above the meaning of 'this' is lost.
Unfortunately
this.element.bind('click', this.onClick ).apply(this); // more or less
what .bindAsEventListener actually does.
won't work - it causes jQuery to issue an error. So how is anyone
supposed to use object methods to handle events, a cornerstone of
object oriented programming?
If I'm to continue using this framework I need to find a solution to
this problem.

[jQuery] Re: JQuery: Dynamically added fields values are not submitted
First of all if you're using jQuery 1.3.x you need to remove the @ at the start of attribute selectors. ie [...@name='blah'] becomes [name='blah']. Second, technically you can't put a form as a direct child of a table. Instead wrap the table in the form. This is why your stuff isn't getting submitted (at least in Firefox).

[jQuery] Re: .load() and timing
You'll probably need to supply a snippet of the relevant bit of your code. It could be a number of things. Make sure you're doing the modifications to the loaded HTML (which will be located in the element you've chosen) in the callback function. You might be better off using the $.get() function or the full ajax() function. They offer a lot more flexibility, such as not directly dumping the newly loaded HTML into the document. You get a chance to process it and put it where you want it to go. Karl Rudd On Mon, Feb 16, 2009 at 4:05 PM, jhm jmay...@gmail.com wrote: I'm new to jquery and so far it's awesome. I've run into a problem, however, that I don't fully understand how to deal with. (sorry for the cross post, if it is one, I accidentally posted this originally in the UI group). I'm using .load() to load a snippet of HTML in response to a click. I need to modify the HTML, based on what was clicked. Even though I do the modifications after the snippet is loaded, the modifications seem to operate on the initial HTML instead of the freshly loaded code. I figure there is a timing issue I'm missing, but I also figure this must be possible. Any advice? Thanks!
[jQuery] Re: .load() and timing
Ajax is asynchronous, which is to say that you make the call to get
the data, then it could take a few seconds for it to appear. During
that time JavaScript code keeps going. So your code for populate
fields most executes before the page snippet is actually loaded.
What you need to do is:
function addActivity(activity, name, id)
{
// load activity snippet
$(#activity).load('activity.html', function() {
// populate fields in a form
$('#ModName').val(name);
$('#ModID').val(id);
});
}
The callback function (that in this case is the second parameter in
the load function) gets called once snippet has actually returned.
Be aware that if the loading fails the callback function still gets
called. If you want more control you'll need to use the $.ajax()
function. http://docs.jquery.com/Ajax/jQuery.ajax#options

Sometimes it needed a bit of a kick to look at the styles again and

[jQuery] Re: test for css selector capability?
You could do this because the .css(attribute) returns the computed
(the result of all the CSS applied) value of an element's CSS
attribute.
It would involve adding a stylesheet to the document with the
particular selector in it, with say a change to the background colour.
Then create elements that should be selected (and add them to the
document), then test the .css('background-color') of the element to
see if it matches the colour in the stylesheet.
Slightly tricky but doable.

[jQuery] Re: how to access checked attribute on a toggle
The name attribute isn't the same as the id attribute (though in
IE it kind of is).
On a side note, XHTML and HTML differ in how you make something checked:
HTML:
input type=checkbox checked
XHTML:
input type=checkbox checked=checked
If you want to select by name you'll need to do this:
$(input[name=tog_0])
Or you could add an id to the checkboc it if you want:
input class=show_tog type=checkbox checked=checked id=tog_0
name=tog_0/
Then your $(#tog_0).attr('checked') will work.
On a side note, jQuery (or $) always return a jQuery object. To check
to see if that object (it acts a bit like an array) actually

[jQuery] Re: Detecting wether an image link is going to work
You could try using the error handler:

I believe it works for all the common browsers.

I've got a page set up where it loads each image on the page, one
after the other. As you can see here:
http://sandbox.exit42design.com/photography/folio_1.html
The problem with this is that if one of the images is broken, it'll
stop in it's tracks and not try to load the next.
Here's an example of how I'm loading the images
$(image[1]).load(function(){
$(#image1).attr({src : image[1].src});
image[2].src= path/to/next/image.jpg;
});
$(image[2]).load(function(){
$(#image2).attr({src : image[2].src});
image[3].src= path/to/next/image3.jpg;
});
So, basically when the first one is loaded, it inserts it onto the
page, and then sets up the next image path, and so on and so on. So I
need a way to detect if image 2 is going to load successfully, because
if it can't image 3 will never be allowed to load.
I tried using an ajax call but I'm not terribly familiar with how to
use it, for example, in an if statement. Can I get this ajax call to
just return a yes or no value of wether or not there was an error or
not?
$.ajax({url:imagesSrc[1], type:'HEAD', error:somefunction})
Thanks for any help. And any other comments/bug reports on the site

[jQuery] Re: Manipulating form field attributes
IE doesn't allow you to change the type of a form element once it's created.
Best solution is to create a new element and add in the value and

[jQuery] Re: failing .click() trigger on element created using .replaceWith()
You are correct. If you replace an element then any handlers
attached to it will be removed.
When you say $('p').click( handleClick ) the handleClick function is
_only_ attached to the currently existing p elements. If you add
more elements later (or remove and replace an existing element), the
handleClick function won't be attached to those new elements.
There are a few solutions:
- manually attach the handler to new elements
- use the liveQuery plugin ( http://plugins.jquery.com/project/livequery/ )
- if you're using jQuery 1.3.1 you can look at the new live
function ( http://docs.jquery.com/Events/live )

Click Specifications on the sub-nav (middle-right of page) and see

The idea is that we want Furniture details and Specifications to
be toggeled with JQuery. The other links to go to separate pages.
The problem is, if you click Furniture details after clicking
Specifications it doesn't trigger the .click() event.
I'm wondering if this is because the object has been modified since

You don't have to select the LI again. Within the each function

[jQuery] Re: New 1.3 feature, native event delegation??
Event delegation and adding event handlers to new elements are
actually two different things.
The event delegation works without any changes. So if you put a

will be triggered too.
The automatic event handler adding uses the live and die functions:

$('.do_it').click(function() { ...stuff... });
Yet if I dynamically create new items using class=do_it, the above

Most likely this has nothing to do with jQuery. IE is rather brittle
in the way it lays out a page. Sometimes it forgets to update the
layout.
Sometimes you can jog its memory by making it refresh the whole
page's layout. For instance in this case add the following code as the
last line in your document.ready function:
$('body').addClass('blah').removeClass('blah');
And everything works.
*shrug* That's IE for you.

The code is being run before the DIVs actually exist. You need to

You shouldn't need to use $.extend in this case. Something like this

jQuery.fn.debug = function() {

Taken from http://docs.jquery.com/Plugins/Authoring
As for your selection code, you need to use find instead of
filter. The filter removes non-matching elements, if you pass in a
form element then it won't do what you want. The find function
works on the child elements of the given elements, which is what you
want.

[jQuery] Re: wild card $('d...@id^=x_div_]') question
Inside an each called function the this variable will be each
(raw) element that's in the list.
So to alert the id of each DIV selected:
x = $('div[id^=x_div_]');
x.each( function(i) {
alert(this.id);
}
Note that it's the raw DOM element, so if you want to do anything
with it using jQuery you need to do $(this).whateverjQueryFunction()
On a side note, don't use the @ anymore. It's been deprecated for a
while and is being removed in the next version of jQuery.

The cross domain JSONP type request doesn't use the XMLHttpRequest

What happens is that a script tag with the requested URL is inserted

I'm troubleshooting a problem where my text wasn't showing up in IE.
I've narrowed the problem down to creating a DOM node dynamically
(with $(html)) and then passing it to append(). In FireFox, append
will add the node as expected; but when passed a dynamically-created
node in IE, it does nothing. No error message is displayed; it just
silently fails, and no node is added to the page.
Here's a trivial example:
$('#myDiv').append($('h2'));
I put that code into the ready event, on a page with a div id=myDiv.
I also added some CSS to put a border on the h2, so I'd be able to see
whether it got added. Result: in FireFox, I can see the border,
proving that the h2 got added. In IE, nothing. No error.
If, instead, I find an existing h2 using its selector (e.g. $
('#myH2')), and append() that (instead of a dynamically-created one),
then IE works fine; it moves that existing element into myDiv. It
appears to just be when a DOM element is dynamically created with $
(html), and then append()ed, that there's a problem.
Full example:
html
head
styleh2{border:1px solid blue;}/style
script src=../vendor/jquery/jquery-1.2.6.js/script
script
$(function(){
$('#myDiv').append($('h2'));
});
/script
/head
body
div id=myDiv/div
/body
/html
Expected behavior: when you run this, you should get a blank page with
a 2px-tall blue line extending across the page. (This is the border
around the h2.) FireFox shows this expected behavior.
Actual behavior (IE6 on Windows): you get a blank page. The status bar
just says Done like usual, and does not show that any errors
occurred.
Is this a bug in jQuery? Or am I misunderstanding how $(html) is meant
to be used?

I suggest adding a class rather than specifically changing the style.
It keeps the presentation (CSS/styling) nicely separate from the

So the JavaScript would be something like (note I changed round the
selector to :text.date, more efficient this way):
$(document).ready(function(){
$(:text.date).each(function (i) {
if(parse(this.value) Date.getTime()) {

Errr I've not heard of AjaxForm(), there's an ajaxForm() method in

If the Form plugin is the one you're referring too then you could
bind a function that calls the ajaxSubmit() function to the change

$('#myFormId')
.submit(function() {
$(this).ajaxSubmit();
return false;

.find(':input').change(function() {

All actions cause the final Price-Sum which should be calculated in

For the price-calculation I need all the time all values in my PHP

[jQuery] Re: jQuery and $.post with PHP and $_POST
Sorry I misread your first post.
No matter what you put in the form nothing will be sent because $.post
doesn't send a form. You have to explicitly supply it with a JSON
type array/object of values to send.
You may want to check out the Form plugin:
http://www.malsup.com/jquery/form/
If you prefer DIY then take a look at:
http://docs.jquery.com/Ajax/serializeArray
There are also a number of tutorials out there, such as:
http://trevordavis.net/blog/tutorial/ajax-forms-with-jquery/

[jQuery] Re: jQuery and $.post with PHP and $_POST
Sorry, typing too fast, reading too little.
Two things are needed:
* $.post needs a callback function so you can get at what is returned.
* the submit handler needs a return false; so the browser won't
continue with the normal submit process.

What I need to do now:
- Allow for other type of inputs to be checked on blur, etc., such as
selects
(Later, I'll add other types of validation, such as numeric, etc.)
Question:
- How do I modify ('input:text.required') to accommodate other types of
required inputs?
- I tried ('input:text.required, input:select.required') and
('input:text.required', 'input:select.required') but that didn't
work

Not quite sure what you're asking. Why would you try to set the

My advice would be to use the Jorn's plugin (

Have a look at the validate method (
http://docs.jquery.com/Plugins/Validation/validate )
According to the documentation to suppress validation on submission
all you need to do is:
$('form').validate({
onsubmit: false
});
Note: I've never used the plugin before, so this is all untested.

Believe me, I've tried.
I worked with it every way I could think of to disable
the default onSubmit event and cause validation only
onblur, but I couldn't make it work.
I haven't heard anything from Jorn, but if you or anyone
knows how to make the validation occur only onblur, please
let me know.
I don't need or want onSubmit at all...I have server-side
validation that will take care of it once it's submitted.

Hi everyone,
How can I send login credentials with jQuery Ajax request (get(), post
() or ajax()) when the page I'm requesting is asking for them before
permitting the access.
Note here that I'm not talking here about form-based authentication.
Thanks in advance.- Hide quoted text -

[jQuery] Re: Replacing document.getElementById()
The $('#id'), or jQuery('#id'), function returns a special jQuery
collection (which acts much like an array in some ways). It does not
return an actual DOM node.
jQuery is a library that helps you select things (via CSS selectors)
and do stuff (usually all at once) to those things.
To check if there was any DOM node selected use:
var o = $('#myid');
if (o.length != 0) {
// do something
}
To get the first DOM node out of a jQuery collection use:
var theNode = $('#myid')[0];
To select multiple objects pass in a string of selectors (just like in CSS):
var myNodes = $('#checkInDate-Deal, #checkOutDate-Deal');
To change an attribute of the selected nodes you can either use the
attr() method:
myNodes.attr('value', 'mm/dd/');
Or in this case, there is a shortcut method:
myNodes.val('mm/dd/');
Something to watch out for is that the each() method (when called on
a jQuery collection object) actually returns the raw DOM nodes,
one at a time. ie:
myNodes.each(function() {
// this == a raw DOM node
});

Hi,
I'm trying change all instances of document.getElementById() with
the jQuery's DOM traversal syntax, however it breaks it everytime.
A simple example is this function:
rm: function(){
var m = document.getElementById('discountMonth');
if(m)
m.selectedIndex = 0;
}
If I change document.getElementById('discountMonth'); to $
('#discountMonth'); or any variation of that it breaks.(I tried
single and double quotes as well as attempting to get the element by
class and so forth with no luck).
The HTML looks like this select onchange=$.bots.rd();return false;
id=discountMonth name=deals[discountMonth]
class=input_deals_dropdownoption value=//select.
The more troublesome issue is with a function like this
rd: function (){
var ds = new Array('checkInDate-Deal', 'checkOutDate-Deal');
$(ds).each(function(i){
el = document.getElementById(ds[i]);
if(el)
el.value = 'mm/dd/';
});
}, ...
With the HTML looking like input type=text onblur=$.bots.rm
();return false; id=checkOutDate-Deal value=mm/dd/
name=checkOutDate class=input_deals/
Any help understanding jQuery's DOM traversal especially with regard
to array iterations would be much appreciated, thanks.
[jQuery] Re: setInterval method call with parameters not working
The setInterval() function can take a string (which is evals) or a
reference to a function (which is the recommended way).
To invoke a function via setInterval/setTimeout with arguments what is
usually done to use an anonymous function/closure.
So something like:
slideshow_interval = setInterval(
function() {
PageMethod(getNextSlideShowItem, [elmID, callerID,
CampaignID, hdnCampaignID], onSuccess, onFail);
),
1000);
On a side note: I wouldn't recommend loading via ajax at such a small
interval (1 second). In the real world the response will frequently
end up taking more than 1 second to return from the server.

[jQuery] Re: Resize an element without affecting the layout
Tables at difficult beasts, they're built to expand with their content. If you want an image that is in a table cell to (appear) to expand over the top of (and outside the bounds of) the cell then you'll have to something like: - duplicate the image element - insert the duplicate image outside the table - position the duplicate image absolutely over the top of the cell/image Karl Rudd On Thu, Nov 20, 2008 at 4:52 AM, vani [EMAIL PROTECTED] wrote: Thanks for replying, but I'm still having trouble making it work.
