Re: [jQuery] Please help (again, sorry)..NextUntil not working
Hi John,
thanks again for your help, unfortunately I have deployed your suggestions
and am still unable to get it to work. You can view my testpage at:
http://members.optusnet.com.au/greg.bird/mm/collapse.html
My .js now reads:
$(document).ready(function(){
BuildNav();
});
//DEFINE NextUntil FUNCTION
$.fn.nextUntil = function(expr) {
var match = [];
this.each(function(){
var cur = this.nextSibling;
while ( cur jQuery.filter( expr, [cur] ).r.length ) {
match = jQuery.merge( match, [ cur ] );
cur = cur.nextSibling;
}
console.log(this,cur,match);
});
return this.pushStack( match, arguments );
};
/*BUILD SIDE NAVIGATION*/
function BuildNav() {
$(#content h2).each(function(){
$(this).nextUntil(h2).wrap(div class='note'/div);
});
}
I have logged the script and it appears that the match array is not being
populated. I suspect that the Jquery.merge function is not triggering
properly
Does this function work with JQUERY 1.0.2? In note in the JQUERY doco that
the function call is now $.merge. Trialled this without success.
My aim here is to put a unique div around each section of the page and then
dynamically create an expand/collapse navigation system. Have already
achieved a similar result with a sliding navigation system. You can see
this at:
http://members.optusnet.com.au/greg.bird/mm/index.html
This was easier as I didn't need to wrap div's around anything, but simply
anchor to the existing H2's
Have you got any suggestions? Do you have any test pages so that I can view
your implementation?
Thanks in advance, Greg

Just include that after you include jquery.js then do the following:
$(#content h2).each(function(){
$(this).nextUntil(h2).wrap(div class='note'/div);
});
Just 3 lines! Not too shabby :)

Re: [jQuery] jQuery API discussion
Hi,
The first time I saw line 1, I had no clue what it was doing. If all it's
doing is running some jquery before the page is loaded, there's _got_ to be
a more intuitive, succinct way to say it.
That is not, what it is doing. It calls the callback-function as soon as the
document is loaded and - if possible - before the Objects included in the
page (like Images, etc.) are loaded.
You can read $(document).load(function() {...}) like: as soon as the
_document_ is _loaded_ execute this _function_.
But function() { is just too frikin' weird
No, that is the way, it works. Just read it like: as soon as _a#shownote_ is
_clicked_ execute this _function_
Readability for people who are relatively new is particularly poured in for
the world of JavaScript.
Well, CSS is not that readable as well - actually in my view it is even worse.
I have the impression that you were able to learn it. That makes me rather
confident, that you can also learn JavaScript. It isn't really that
complicated - you already have the best tool to make it easier for you:
jQuery.
Lots of people add a little JavaScript to a page
and then don't do much more coding for another couple of months.
Well, then they should listen to the german yellow-pages-advertisements: He
should have asked someone who knows the ropes. Sorry, but if I (as a
programmer) only design a Logo once in a while I ask someone else to do it.
Not that I could't lean how to do it - I'm actually rahter good at painting
and my taste isn't that bad as well, it is just that I don't whant to invest
the time for learning and don't expect fried doves to fly into my mouth.
JQuery makes your life a lot easier, but you can't programm without
programming - even with jQuery.

Re: [jQuery] jQuery API discussion
Anders,I have to disagree with your view about the readability of jquery. I have little to no knowledge of _javascript_...and the only reason that I started using jquery is because it is so simple to understand the basics (prototype and dojo are a foreign language to mebut jquery is plain and simple).if you can read a stylesheet, then you can surely take the first steps in using jquery to add some pizzaz to your sitethen the rest is up to the individual...if you want to take the timeout to read and learn, both from the mailing list and by looking at the plug ins that have been contributed..you can take the next steps forward...jquery makes writing _javascript_ easy.it does not do things for you automatically...

[jQuery] Intro + suggestion (plugin repository)
Hello, It's my first post, so let me introduce myself. I'm a jquery newbie, somewhat knowledgeable at javascript, php, and web applications in general. I'm the developer of thinkedit (www.thinkedit.org) yet another php CMS. We choosed jquery to add easily some dynamic behaviour to the admin interface of this cms. Currently, very little has been done in this direction. The main thing to do is to build a tree ui for the management of nodes inside the cms. This being said, I have a first question / proposal : is there a plan to have a solid plugin repository ? It would be great to have a central place where authors can add plugins, with structured informations : - author - last updated - compatibility with jquery version x and upper (very important if you plan to change the api) - user rating - user comments - svn access This looks like a lot of work, but this would help a lot. I'm always a bit in discomfort to copy and paste some plugin code from some unknown people on a production site. This would also help collaboration on plugins. Maybe I'm dreaming, or maybe it already exists, or maybe it's too early ? Anyway, thanks a lot for this refreshing way of using javascript ! -- Philippe Jadin Thinkedit, a flexible data and content management system : http://www.thinkedit.org ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/

One more thing: the dev PC at work does not show a problem with IE with

At home, 249 works perfectly but fails as soon as I try the 413 version.
Is it possible that the memory leak fixes (that I understand are in the

Re: [jQuery] ThickBox in Filemanager
PDFs in object tags have numerous problems and the widespread consensus is generally not to use such things. PDFs in iframes are possible (https://secure.marketech.us/php/framedemo/), and I might just retract what I said earlier if I can get a PDF to open in a thickbox iframe. Michael Geary wrote: Well, as I've already said, you won't be able to show the PDF in a thickbox, because the OS/browser will catch the link and try to open it using the default action set in the browser or OS, and there's nothing that you can do to override it. If no default action is set, then you -might- be able to open it in the browser. But let's be honest, the percentage of users without a PDF reader is pretty small (probably the same percentage as those browsing the web on an Amiga 1200. :-) As far as I know, there is no ability to read PDF's inline like you're trying to do, and trying to force PDFs to open in a small window just isn't practical, and users won't like it if you force it upon them. If you can load HTML into the thickbox, you can easily load a PDF file. Simply use an iframe or object tag.

[jQuery] Submitting a form after input type=file onchange
Hello,
This is my first post to the list. I am still new to jQuery and so far I think it is the best lib available. You
guys rock!
Anyways, I have a question regarding a form I am trying to
submit using jQuery. I was using an inline onchange event to trigger the form submit for an file input box.
Here is the html and js:
$(document).ready(function() { $(#file).change(function() { alert(change); uploadPhoto(); });});var uploadPhoto = function() { $(/html/body/div/form).submit(function() { alert(inside); });}form name=photo id=photo-upload-form action=/ method=get enctype=multipart/form-datadivlabel for=imageFind Your Photo/labelinput id=file type=file name=image //div/form
I can get an alert to fire inside the uploadPhoto
function, but not inside the submit function. I was worried that I wasnt
targeting the form correctly, so I used firebug to find the XPath
to it. I am not sure why it isnt working.
Thanks,

Re: [jQuery] SVN and firewall issues
@SamYup.. I'm in that boat as well. HTTP svn attempts fail complaining about PROPFIND. The only svn access I've ever gotten to work is HTTPS. I can get to projects hosted on Google Code like that, but unless a project has a cert and allows HTTPS access to the repo, I'm out of luck. I'm going to try submitting a request to open this stuff, but I seriously doubt they'll do anything about it. I know it'd be trivially easy to have a post commit script generate a tar.gz of the repo and move it to a spot on the web server for easy download.

Re: [jQuery] Jquery.css function poor performance
After further tests I realize that most of the time is spent in getting the height and width of the passed element: oHeight = e.offsetHeight;oWidth = e.offsetWidth; Since this calculated by the browser I don't think there's much to do. What do you think? I'm using IE 6; I don't know if the same delay is present in other browsers (probably it is).

Re: [jQuery] Submitting a form after input type=file onchange
You're nearly there. You've just got a slight problem in your understanding of what the $().submit(func) function does. What you're doing is adding an onsubmit handler to the form whenever the contents of the file input element is changed. But, that function won't fire until the form is actually submitted. I implemented your code, and the inside alert pops up just fine when I added a submit input element and used it. If you want it to submit automatically when you've changed the file input, add another empty .submit() function after the one you have. Your new function will look like this:
$(form#photo-upload-form) .submit(function() {alert(inside);})
.submit();Of course, if you just wanted the form to autosubmit, just remove your function from inside the first .submit() call and it will submit the form. In the form above it will allow you to run some arbitrary code before the submission.
I also changed your query from the xpath to the ID of the form tag. Why not use it since it was already there.On 10/18/06, Marshall Salinger

Re: [jQuery] Submitting a form after input type=file onchange
$(form#photo-upload-form)

That won't work. You have to get out the DOM node out of the jQuery
object first before calling submit() on it:
$(#photo-upload-form)
.submit(function() {alert(inside);})
[0].submit();
^^^
You have to be always careful with such code. Once the element
#photo-upload-form is not found for whatever reason an error will be
thrown, because yor are calling a function on undefined.
Speaking of optimizing queries, leave away the element type form in
front of your id selector as well.

[jQuery] Interface - dragging nodes containing text areas (Firefox, Safari)
I've got an issue with using the Interface idrag.js. The Interface website implies I should be asking here for support issues.I have a DOM structure that contains, amongst other things, a text field and a textArea. What I find when I drag the object in Firefox is that any text I might have typed into the textArea disappears, and when I stop the drag it re-appears.I have dug into the idrag.js source and found that it works by doing a cloneNode(true) on the object being dragged and hiding the original. That cloned node is then appended to a dragHelper at the top level of the HTML tree, presumably to avoid having to deal with issues of dragging things from deeper structures and calculating drop positions, etc. Whatever the reason, what I see (using the DOM inspector from the web developer toolbar for Firefox) is that the node tree is correctly cloned, except that the "value" property of the textArea is not replicated. Hence the cloned drag object has no text in it.The problem is worse in Safari as the text field text also disappears during the drag. In IE it all works fine (not often you hear those words :-)A further wrinkle is that if the original text area contained initial text within tag (e.g. "textarea class='text' rows="8"flibble/textarea") then that text (in this case "flibble") appears during the drag, even if I have typed new text into the textArea before dragging.Has anyone else come across this problem and found any way of addressing it? If there is no easy fix then I'll probably have to change the Interface drag code itself.Doug___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/

Re: [jQuery] Please help (again, sorry)..NextUntil not working
Ok, I did some more digging and you're right. I don't think I ever
actually tested nextUntil (oops!)
The full implementation can be found here:
http://john.jquery.com/jquery/test/nextuntil.html
This includes a working version of nextUntil:
$.fn.nextUntil = function(expr) {
var match = [];
// We need to figure out which elements to push onto the array
this.each(function(){
// Traverse through the sibling nodes
for( var i = this.nextSibling; i; i = i.nextSibling ) {
// Make sure that we're only dealing with elements
if ( i.nodeType != 1 ) continue;
// If we find a match then we need to stop
if ( jQuery.filter( expr, [i] ).r.length ) break;
// Otherwise, add it on to the stack
match.push( i );
}
});
return this.pushStack( match, arguments );
};
Additionally, I realized that .wrap() isn't going to do what you need
it to. .wrap() wraps each matched element with the same structure. So
if you matched 3 paragraphs, you'd have three surrounding divs too.
Since you want it to wrap all of the matched elements with a single
element, I made a new .wrapAll() plugin:
$.fn.wrapAll = function() {
// There needs to be at least one matched element for this to work
if ( !this.length ) return this;
// Find the element that we're wrapping with
var b = jQuery.clean(arguments)[0];
// Make sure that its in the right position in the DOM
this[0].parentNode.insertBefore( b, this[0] );
// Find its lowest point
while ( b.firstChild ) b = b.firstChild;
// And add all the elements there
return this.appendTo(b);
};
So - all of that should help you along now. Let me know if this works for you.

It relies on the assumption that appendTo moves the origonal element list,
rather than clones them. Basically:
1. It adds your div before the heading, with a temporary marker so we
can find it again
2. Selects all elements until the next heading
3. Moves them to the div
4. Removes the marker from the div

I have logged the script and it appears that the match array is not
being
populated. I suspect that the Jquery.merge function is not triggering
properly
Does this function work with JQUERY 1.0.2? In note in the JQUERY doco
that
the function call is now $.merge. Trialled this without success.
My aim here is to put a unique div around each section of the page and
then
dynamically create an expand/collapse navigation system. Have already
achieved a similar result with a sliding navigation system. You can see
this at:
http://members.optusnet.com.au/greg.bird/mm/index.html
This was easier as I didn't need to wrap div's around anything, but
simply
anchor to the existing H2's
Have you got any suggestions? Do you have any test pages so that I can
view
your implementation?

Yes, I removed support for those selectors, since they're virtually useless, in most respects.

Were you attempting to use them for something, or just curious? I was thinking about the possibility of creating a new selector for a quite strange markup I'm working on. As I saw the `:anything` has been extended by plugins, I thought it'd be interesting to write my own extension to (punish me) use something like this: [EMAIL PROTECTED]|=pare] which should match both tr class=pare-0 / and tr class=fill-0 pare-1 / Anyway, I can select every `tr` and iterate through them, so... there is a workaround simpler than what I intended to do.

Re: [jQuery] How to bind a function only once
Hi Brian -
Here is how I would change your code:
$('[EMAIL PROTECTED]').click(function(){
$('#label').unbind('change');
if ( $([EMAIL PROTECTED]'label_checkbox']:checked).length )
$('#label').bind('change', function(){
alert('test');
});
});
By making it such that the change event is always unbound from the
select, when a checkbox changes, you're guaranteed to never have more
than one bound at a time. Hope this helps.

Re: [jQuery] Setting Height in FF
Glen,
You need to append the px on the end.
A call to $(#right).height(); simply returns the integer, to set height,
according to the jquery-1.0.2 API, you need the px:
script
$(document).ready(function() {
var rightHeight = $(#right).height();
$(#left).height(rightHeight + px);
});
/script

Re: [jQuery] Handling unsupported browsers
The jQuery philosophy has made it much easier to deal with downlevel browsers for me. When I need compatibility, I build the page as I would if I weren't using javascript at all. Links all have hrefs to relevant places, elements that should be updated dynamically are filled with data on the server side, etc. Once I'm to that point, I start making jQuery do the cool things. The browsers that can support it get setup within the .ready() event. As an example, one of the sites I work on has a number of journals that need to be featured on the frontpage. The new version will have a little tabbed control that updates a headline list. The tabs themselves are completely functional without javascript, they simply have hrefs to each individual journal. With jQuery enabled, my super special function grabs that href, alters it to get a json result, then uses that to reload the headlines. The advantage to this approach is: you end up with semantically appropriate HTML, and the dynamic functionality is decoupled from the page markup. You won't find a href=# anywhere. :) So, in summary: build the downlevel functionality first, add the cool stuff on top of that. You'll get cleaner HTML, and it will degrade gracefully. -Kurt -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Chabot Sent: Wednesday, October 18, 2006 11:53 AM To: discuss@jquery.com Subject: [jQuery] Handling unsupported browsers Does anyone have a preferred way for handling browsers that are not officially supported by jQuery, such as Netscape?

Re: [jQuery] Interface - dragging nodes containing text areas (Firefox, Safari)
I've got an issue with using the Interface idrag.js. ... what I see (using the DOM inspector from the web developer toolbar for Firefox) is that the node tree is correctly cloned, except that the value property of the textArea is not replicated. Hence the cloned drag object has no text in it. ...

[jQuery] Unable to bind click function in a dynamically created object?

i got a bit of a stumper for ya, trying to bind a function to the
click event of each link in a dynamically generated list.
i have a bunch of long content pages that we're breaking up into
subpages, with a sidenav to navigate through them. the markup for
each page is as follows:
div class=page
h3Page One Title/h3
p/p
p/p
/div
div class=page
h3Another Page Title/h3
p/p
p/p
/div
here's the function that sets up the list of links and stuffs them
into the sidenav.
$('.page').each(function(i) {
var title = $('h3',this).eq(0).text();
var link = $('lia href=#page'+(i+1)+''+title+'/a/li');
$('.sidenav ul').append(link);
$('a',link).click(function() {
alert(1);
// $('.page',pages).hide();
// $(page).show();
});
});
$('.page').hide().eq(0).show();
it grabs the text of the first H3 in each section to use as the link
text. it builds an LI element containing the link, then appends that
to the sidenav. then it tries to assign a click handler to the link.
i've commented out the functional part of the click function and just
put in an alert for testing, but the function isn't firing when i
click these links. am i missing something?

Re: [jQuery] Handling unsupported browsers
Does anyone have a preferred way for handling browsers that are not
officially supported by jQuery, such as Netscape? What I am planning
on doing is having server-side browser detection code which gives me
the browser name, platform, and version number, then in my site,
having each page coded in two different ways: one for Ajax and one
without Ajax. Is this what other people do?
Server-side browser detection is unreliable due to User Agent spoofing.
It's much better to just code your pages so that the JavaScript
features are tacked on transparently, and have a usable alternative
when JavaScript is turned off. That way, you can treat any broken
browser as one which does not support JavaScript.
You can use several tricks to do this in a relatively seamless way:
1) Define a global variable jsEnabled or something, which checks
for required DOM functions. For example:
var jsEnabled = document.getElementsByTagName
document.createElement document.createTextNode
document.documentElement document.getElementById;
Then, you can augment this with browser-specific denials if there are
still problems.
2) In the global scope (NOT in .ready()), you set a class on the
html element:
if (jsEnabled) {
document.documentElement.className = 'js';
}
3) Then, you define a bunch of CSS rules with the ancestor selector
html.js (e.g. html.js #myelement) where you apply the required
styles for JavaScript-based features. This can include hiding
collapsed section of the page, making Ajax widgets visible, etc.
4) Any additional changes that need to be made to the source document
are done in $(document).ready(), but also only if (jsEnabled) is true.
This gives you the best of both worlds: you avoid non-JavaScript
users seeing useless widgets on the page or having inaccessible
content, while JavaScript users don't see the page change drastically
as soon as it finished loading. Remember: even with $(document).ready
() there is the possibility of incremental rendering.
Then, when you tell your users to turn on JavaScript or switch
browsers, it's not an ultimatum: it's a choice for them, if they want
a better user experience, but they can't still see and use your site.

I see one thing that may cause the problem: your variable link is a
jQuery object. This is passed as context a few lines later on, but you
have to pass a DOM node as context to the $ function.
Try this:
$('a', link[0]).click(...);
Or to overall shorten the code:
var link = $('li ... /li').appendTo('.sidenav ul')[0];
$('a', link).click(...);
Does that help?

Re: [jQuery] Handling unsupported browsers
Kurt, That is a great strategy and it should work in most cases. Here is my thinking of what a typical plan would be: 1. Load a page that works assuming Ajax is not available 2. Use the ready() function to hide the content that should be made fancier 3. Make an Ajax call to pull in the fancier code. Problem is, some Netscape browsers get past step 2, but either fail or crash on step 3, potentially leaving a missing section of the page or an angry user that has to restart their browser, only to encounter the same problem the next time around. The AjaxStart method executes, but the actual Ajax call ends up failing. That is why I think I need some browser detection so that the jQuery code is not there at all in these unsupported browsers. FYI, the specific code I am working on is just a double-select list, where the content of select list #2 depends on select list #1. It is nothing overly fancy, but enough people use Netscape 7+ that I need to come up with a work-around.

The advantage to this approach is: you end up with semantically appropriate HTML, and the dynamic functionality is decoupled from the page markup. You won't find a href=# anywhere. :) So, in summary: build the downlevel functionality first, add the cool stuff on top of that. You'll get cleaner HTML, and it will degrade gracefully. -Kurt -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Chabot Sent: Wednesday, October 18, 2006 11:53 AM To: discuss@jquery.com Subject: [jQuery] Handling unsupported browsers Does anyone have a preferred way for handling browsers that are not officially supported by jQuery, such as Netscape?

it grabs the text of the first H3 in each section to use as the link
text. it builds an LI element containing the link, then appends that
to the sidenav. then it tries to assign a click handler to the link.
i've commented out the functional part of the click function and just
put in an alert for testing, but the function isn't firing when i
click these links. am i missing something?

Re: [jQuery] Submitting a form after input type=file onchange

Ok, I did some more digging and you're right. I don't think I ever
actually tested nextUntil (oops!)
The full implementation can be found here:
http://john.jquery.com/jquery/test/nextuntil.html
This includes a working version of nextUntil:
$.fn.nextUntil = function(expr) {
var match = [];
// We need to figure out which elements to push onto the array
this.each(function(){
// Traverse through the sibling nodes
for( var i = this.nextSibling; i; i = i.nextSibling ) {
// Make sure that we're only dealing with elements
if ( i.nodeType != 1 ) continue;
// If we find a match then we need to stop
if ( jQuery.filter( expr, [i] ).r.length ) break;
// Otherwise, add it on to the stack
match.push( i );
}
});
return this.pushStack( match, arguments );
};
Additionally, I realized that .wrap() isn't going to do what you need
it to. .wrap() wraps each matched element with the same structure. So
if you matched 3 paragraphs, you'd have three surrounding divs too.
Since you want it to wrap all of the matched elements with a single
element, I made a new .wrapAll() plugin:
$.fn.wrapAll = function() {
// There needs to be at least one matched element for this to work
if ( !this.length ) return this;
// Find the element that we're wrapping with
var b = jQuery.clean(arguments)[0];
// Make sure that its in the right position in the DOM
this[0].parentNode.insertBefore( b, this[0] );
// Find its lowest point
while ( b.firstChild ) b = b.firstChild;
// And add all the elements there
return this.appendTo(b);
};
So - all of that should help you along now. Let me know if this
works for you.

It relies on the assumption that appendTo moves the origonal
element list,
rather than clones them. Basically:
1. It adds your div before the heading, with a temporary
marker so we
can find it again
2. Selects all elements until the next heading
3. Moves them to the div
4. Removes the marker from the div

[jQuery] How to make input readonly with jQuery in IE
I've found some inconsistent behavior in IE vs. FF and was wondering if someone might know a workaround.I have some form fields, for which the HTML is generated by a template system out of my control. I want to set some of the fields to readonly so I wrap them in a span that has a readonly class. The HTML looks like this:
span class=readonlyinput type=textSome text/input/spanI have tried each of the following queries and none of them have the desired effect. Its like they aren't modifying the DOM.
$(span.readonly input).attr(readonly, readonly); $(span.readonly input).attr(disabled, disabled); $(span.readonly
input).focus(function() { $(this).blur(); });These work (with varying effects) in FF but not in IE. However if I manually put the attributes (or script) on an input field in IE it does work. I know I have the queryright because I did this
$(span.readonly input).focus(function() { alert('here'); });and I get a popup when I click on the field.Can anyone help with this?Thanks,-Dave

The issue is that that the trs are returned in the order in which

returned first. So the best way to do this is by doing:
$(...).parents(tr:last)
Which will give you the last tr found (but the one closest to your

[jQuery] jQuery history plugin - from making the back button work to a more elaborate Hijax solution
Hi jQuerians,
people demanded, so I started to extract the history functionality from
the tabs plugin to make a standalone plugin out of it.
Worked out so far:
http://stilbuero.de/jquery/history/
http://stilbuero.de/jquery/tabs/
It's still alpha, support for Firefox, Safari and Opera is there, IE not
yet but will be added. Also todo is to automatically show the
appropriate part, if the hash in the url refers to some point in the
history but I can borrow that from the tabs plugin as well.
At the moment it works by hooking into links and adding an event
handler, like (prototypical code, setHash is required by Safari):
$('a').click(function(e) {
$.history.setHash('#' + this.href.split('#')[1], e);
});
That's ok for me, I think its important to be able to control which
links should be observed anyway. So the snippet above might become
$('a.hijax').history();
with
jQuery.fn.history = function() {
return this.each(function() {
$(this).click(function(e) {
jQuery.history.setHash('#' + this.href.split('#')[1]);
});
});
};
Or maybe it is reasonable to use a custom event? I'd like that:
$('a.hijax').bind('history', function() {...}).click(function() {
$(this).trigger('history');
});
Does that work?
But:
You all know, I'm all for unobtrusive JS and the concept of progressive
enhancement. I don't like having a link in my HTML like a
href=#chapter-1 which actually points nowhere with JS disabled.
Why not implement a better solution for being able to implement Hijax
the easy way (like what the form module is already offering)?
So the links stay as they are and point to an existing ressource:
a href=chapter-1.php
Then I intercept all these links, change the href value to hashes and
load on click the content from the URL of the initial href value via
XHR. Links that already have a hash in their URL won't load via XHR but
add to history (that is needed to stay compatible with tabs).
That would 1. result in history support (in most browsers) and 2. in a
nice gracefully degrading application with JS disabled or for browsers
not supported by jQuery. Totally unobtrusive.
That concept would of course involve the back-end as well. There it must
be decided upon the X-Requested-With request header what to send back
(whole page or only the part of the page that needs to be updated.
What do you guys think? Feedback and ideas welcome...

Re: [jQuery] How to safely get the clickTarget of an event?
If you mean the element, use 'this' inside the function to refer to the clicked element.

Re: [jQuery] parent()
Hey Blair,That did the trick. Thanks for the help.But I must (regretfully) say that the documentation on this point is lacking.It seems to me that parents() and ancestors() are the same except for the order of objects returned.
parents() = parent[0], grandparent[1]ancestors() = grandparent[0], parent[1]Perhaps the someone could add this simple explanation to the documentation.I appreciate everyone's help,Derrek

Re: [jQuery] Please help (again, sorry)..NextUntil not working
Man, you are amazing at this stuff. Really appreciate all the effort you
have taken, particularly putting up the test case.
I am new to the mailing list and can't get past how prolific you are. You
must live and breath this stuff. It is great to find someone so willing to
help out!!!
I have implemented your code and it works BEAUTIFULLY, straight out of the
box. I will now go ahead and construct the dynamic navigation part. Will
fire the URL to you when I've finished so you can have a look at where I was
headed with this.
Thanks again,
Cheers, Greg
Hat's off, Greg
John Resig wrote:
Ok, I did some more digging and you're right. I don't think I ever
actually tested nextUntil (oops!)
The full implementation can be found here:
http://john.jquery.com/jquery/test/nextuntil.html
This includes a working version of nextUntil:
$.fn.nextUntil = function(expr) {
var match = [];
// We need to figure out which elements to push onto the array
this.each(function(){
// Traverse through the sibling nodes
for( var i = this.nextSibling; i; i = i.nextSibling ) {
// Make sure that we're only dealing with elements
if ( i.nodeType != 1 ) continue;
// If we find a match then we need to stop
if ( jQuery.filter( expr, [i] ).r.length ) break;
// Otherwise, add it on to the stack
match.push( i );
}
});
return this.pushStack( match, arguments );
};
Additionally, I realized that .wrap() isn't going to do what you need
it to. .wrap() wraps each matched element with the same structure. So
if you matched 3 paragraphs, you'd have three surrounding divs too.
Since you want it to wrap all of the matched elements with a single
element, I made a new .wrapAll() plugin:
$.fn.wrapAll = function() {
// There needs to be at least one matched element for this to work
if ( !this.length ) return this;
// Find the element that we're wrapping with
var b = jQuery.clean(arguments)[0];
// Make sure that its in the right position in the DOM
this[0].parentNode.insertBefore( b, this[0] );
// Find its lowest point
while ( b.firstChild ) b = b.firstChild;
// And add all the elements there
return this.appendTo(b);
};
So - all of that should help you along now. Let me know if this works for
you.

This is just a guess:

$(this).before(div class='note

$(

}
It relies on the assumption that appendTo moves the origonal element
list,
rather than clones them. Basically:
1. It adds your div before the heading, with a temporary marker so
we
can find it again
2. Selects all elements until the next heading
3. Moves them to the div
4. Removes the marker from the div

Hi John,
thanks again for your help, unfortunately I have deployed your
suggestions
and am still unable to get it to work. You can view my testpage at:
http://members.optusnet.com.au/greg.bird/mm/collapse.html
My .js now reads:
$(document).ready(function(){
BuildNav();
});
//DEFINE NextUntil FUNCTION
$.fn.nextUntil = function(expr) {
var match = [];
this.each(function(){
var cur = this.nextSibling;
while ( cur jQuery.filter( expr, [cur] ).r.length ) {
match = jQuery.merge( match, [ cur ] );
cur = cur.nextSibling;
}
console.log(this,cur,match);
});
return this.pushStack( match, arguments );
};
/*BUILD SIDE NAVIGATION*/
function BuildNav() {
$(#content h2).each(function(){
$(this).nextUntil(h2).wrap(div class='note'/div);
});
}
I have logged the script and it appears that the match array is not
being
populated. I suspect that the Jquery.merge function is not triggering
properly
Does this function work with JQUERY 1.0.2? In note in the JQUERY doco
that
the function call is now $.merge. Trialled this without success.
My aim here is to put a unique div around each section of the page and
then
dynamically create an expand/collapse navigation system. Have already
achieved a similar result with a sliding navigation system. You can
see
this at:

This was easier as I didn't need to wrap
Re: [jQuery] Popup window reference problem
I have tried to directly use the window reference.
i.e.
var abc = ref.document.getElementById(abc1);
abc.parentNode.removeChild(abc);
The result is correct that the input box in popup windows being removed.
Seems that jQuery cannot use popup window reference?

[jQuery] Tablesorter
I have a need to have the tablesorter do the following:1) Refresh when I need it to (I'm going to be doing DOM insertions, and will need to refresh the table after an insertion). The best thing I could think of thus far is $(.sortUp, .sortDown).click().click(). Obviously not the best idea. 2) Use custom sorters.

Re: [jQuery] fundamentals: .index(obj) or better solution
John - Thank you, that worked! Part of what confused me was that index() is defined as having an Obj as the argument, but not what kind - my attempts at using an expression as an argument were failing, so I was running out of ideas. I wasn't following context properly. Have enjoyed working with jQuery lately, nice update. -- mike John Resig wrote: .index() doesn't do what you think it does. It works like this: // Find the position of the P that an ID of someP /within/ the list of p elements. $(p).index( $(#someP)[0] ) So, in your code it would be something like this: // div i want to find id = 3; // get the element i want to move var curr_obj = $([EMAIL PROTECTED]'id[]'[EMAIL PROTECTED]'+id+']).parent()[0]; // determine its current location within the set of list_items var old_pos = $(div.list_item).index(curr_obj); So two things to note: .get() returns an array of elements, not just a single element and .index() works over a list of elements, not the children of an element.
