[jQuery] Re: trigger "$(document).ready" manually

[MathiasBank]

Ok, it's quite easy to recall ready:

Don't register your ready functions like this:

$(document).ready(...);

Register it like this:

$(document).bind("ready",...);

Now, trigger the ready event:

$(document).trigger("ready");

This works. I think, it's a bit confusing, because $(document).ready
is an event (at least in the api). So, I expect, that it can be called
like an event.

[jQuery] Re: trigger "$(document).ready" manually

[MathiasBank]

Well, I have an ajax call to the server. The sever decides what to do.
Normally, there is just one small part of the page, which will be
changed per json. But there is one possibility, which needs to refresh
nearly the complete page. No I have to recall ready. There are three
possibilites:

1. I can send a special state which will reload the complete page.
This method is stupid, because I need an additional server request (I
can send the data with the first response).
2. I can write a special function, which will be called in $
(ducument).ready(). But this is just a workaround
3. ready can be called. I think, that's the most obvious way, the
problem can be solved. And it is the easiest. If it is not possible
yet, it's a feature request ;)

I'm not sure what you are really after.  If you are after the text
content of an element, then something like the following will do the
trick:

 function getText(el) {
   if (typeof el.textContent == 'string') return el.textContent;
   if (typeof el.innerHTML == 'string') return el.innerHTML;
 }

However, if you really are after the first text node that is child of
the element, loop over the child nodes:

 function getFirstTextNode(el) {
   var kids = el.childNodes;
   for (var i=0, len=kids.length; i

[jQuery] Dragging from a Drupal block to tinyMCE

[Phil Glatz]

I'm using Drupal 5.1 and jquery to build a site where members can
create content. I wrote a module to display a list of available images
and videos in a list in a block. I'd like to be able to select an item
from the list and drag it into the article body textarea, and
wondering if this can be done without modification of core Dupal
functions. If drag&drop is not possible, could this be done by
selecting an item and clicking in the textarea?

I'd appreciate any example or tutorials on how this could be done.

[jQuery] Re: getting DOM values

[Brandon Aaron]

You can access the regular dom properties/methods by extracting the
element from the jQuery collection.

$('#foo').get(0).clientWidth

You can also just use bracket notation.

$('#foo')[0].clientWidth

You could also use the Dimensions plugin which helps abstract some
cross browser issues with widths, heights and offsets.

[jQuery] menuing recommendation?

[Jack Killpatrick]

Hi All,

I'm looking for a jquery based menuing plugin ala:

http://jdsharp.us/jQuery/plugins/jdMenu/

It has to be able to do the following:

1. allow on/off images for top level menu items: either background 
images or both foreground and background images (for typeset foregrounds)


2. have a means to style the "current" (currently selected) top level 
menu item, also allowing images (back/fore). I can hack up something for 
"current" items, but it'd be nice if it was natively supported. Must 
allow images, though.


3. work in ie6+, ff 1.x+, safari: including hovers and SELECT (see 
through) blocking


Does such a critter exist?

TIA,
Jack

Andy,

I believe IE always has the value attribute defined--even if it's not
defined in your markup (ie. it essentially adds a value="" to your tag.) If
you know the 2nd element should have a value attribute if it's present, then
I'd just do:

$('#RedMakeSelect:first-child option:nth-child(1)')

Dave, I was shocked when you got the first answer. I don't think there is
any way to get just the text using jQuery core functions.

If you get .html() you can use regexps to remove the complete nodes, it
seems messy.

if you write a plugin (there may already be one) it can go thru the dom
nodes and return the concatenation of the simple text nodes.

[jQuery] Help with form plugin and tabs in a same page

[Web Specialist]

Hi all

I have a very basic form with Jorn Form Validation and Tabs plugins inside.
Looks very simple like:


   
   
   Personal data
   Family data
   Professional data
   References
   
   
. form content for personal data

and so on...


Is it possible after validation to change the color for tabs title when
occurs any error inside? For example:

- user fills family data and after submit that form occurs an error based in
Family data. I'll want to change that Family data(tabs title) to red.

What do you think about? How to know the error context and tab context?

Cheers

[Sean Catchpole]

Mathias,

The solution is simplier than it seems.

function foo(){...}

$(document).ready(foo);

//someplace where you want to call the document.ready again
foo();

By wrapping the code that you want to call from document.ready inside
a function it is easy to call again at any time.

Of course if you don't have control of all the code that runs at
document.ready, then we must become more clever in our solution, but
hopefully that is not the case.

I'm writing this off the top of my head, but it should be at least
close to functional.

jQ: $("#id1").children().filter(function(){return

Or if you intend to use this a lot, you could write a small plugin:
(function($){
$.fn.textNode(index){
 index = index || 0;
 return this.children().filter(function(){return
$(this).text()!="";}).filter(":eq("+index+")").text();
})(jQuery);

Good evening,

2. $(document).trigger("myOwnEvent");

[jQuery] Re: object detection in jQuery

[Daemach]

You can use a selector such as $('#myElem') to get an element by ID.  $
('#myElem').size() gives you the size of the matched set - you can use
that in an if statement if you want.

One of the great things about jQuery, however, is the basic concept.
If it doesn't find the element it doesn't do anything so there is no
need for conditional logic ;)

[jQuery] Re: jQuery'zed Ext.Template

[Rodrigo Moraes]

Hi,
Sorry to reply to myself. :)
I've updated the Template plugin to use $.extend() in a new
$.extendClass() function. This is probably Javascript 101, but I
couldn't go ahead from this point. If somebody can point me an example
of a extended class/constructor/prototype in jQuery, maybe I can take
a look and try to follow it.

I know how to override a class prototype using $.extend(), but not how
to provide a inheritance mechanism so a class can, for example, call
its parent constructor. Well, I saw some mechanisms like
YAHOO.extend() or Ext.extend(), but I would like to make the plugin as
jQuery'zed as I can, so any help would be appreciated.

Here's the updated code:

[jQuery] Re: Help Test jQuery 1.1.3

[Brian Cherne]

Hi John, I quickly tested jQuery 1.1.3a with my jVariations plug-in and it
crashed Safari (immediately). I'm going to take a look into it this week and
will hopefully be able to provide more information. The page I was testing
it on was quite complex and Safari was already struggling (taking a few
seconds to update) with jQuery 1.1.2... so I'm hoping it's just bad/sloppy
code on my end. Firefox and WinIE6/7 had no performance problems.

There's a lot going on in that little plug-in, so it's hard to tell exactly
where it's failing in Safari. Is there a list of what's changed in jQuery
1.1.3a ? Has anyone run into Safari-specific performance issues?

The code that is killing Safari is for a client project, so I cannot share
it at this time. I'll try to simplify the code for testing, remove all
client-specific references, and share my findings with the list (and enter a
ticket if necessary).

My other plug-in, hoverIntent, showed no problems with 1.1.3a in my limited
testing.

Brian.

Are you using your scroll wheel or arrow keys to select from the
menu?  I've noticed that ie doesn't fire the change event until you
tab out of the select while firefox fires the onchange event every
time you make a new selection (at least on my mac)  You can save
yourself a lot of debugging time by using the firebug firefox extension.

[Jonathan Sharp]

You can't block across requests. You may achieve your desired effect if your

In short you can block when the user clicks submit but at an arbitrary point
in time the browser will clear the screen as it receives the response. So
there isn't really a way to do what you want.

[Erik Beeson]

Alternatively, instead of unbinding the event, you could have your
event handler check for some condition:

$('div#topLineHover').bind('mouseover', function() {
   if($('#topLine').is(':hidden')) {
$('#topLine').slideDown('slow');
   }
});

Also, when selecting by ID, no need to specify a tag name. So
div#topLineHover should be #topLineHover.

A couple of more notes on this.

1) Instead of attaching the event to the document, you could attach it to
the a specific parent element (i.e. $("ol.icons") instead of $(document).)
This would obviously save some processing.

2) The other benefit of this method, is that you won't need to "reattach"
the behavior if you replace the inner contents of "ol.icons". This means you
can repopulate the images with a different subset loaded dynamically,
without having to re-parse the elements on each dynamic load.
  
Another note: Using event.target should be good enough, as jQuery 
normalizes target in IE (srcElement) and Safari (fix textnodes).

.parents(expr) supports an expression to filter parent elements,

the $(expr) in general allows any css (or xml) selector.  Does expr

Thanks, John. I tried it first, but it doesn't seem appropriate in
this case. I can't use superclass in the extended class (Error:
$.MasterTemplate.superclass has no properties), and uh, I don't
understand this completelly.

So I've duplicated Ext.extend() [1] (similar to YAHOO.extend() [2]) to
get it working. I wonder if I could use something that's already used
by other plugins / core to extend a class in such way, to avoiding
including the function and instead use an existing solution.

[jQuery] Block UI when user submits a slow page

[Web Specialist]

Hi all

do you know any example using BlockUI with "normal" form(otherwise Ajax)?

I have a very slow form(processing text files). I'll want to block UI when
user submits that form and, after execute that page, unblock again.

Cheers

http://docs.jquery.com/Ajax would be a good start =).

You'll want to make an Ajax call ($.ajax, $.get, $.post... whichever)
and use "data" to pass back data to PHP.

[jQuery] Re: < id=__ie_init defer=true src=//:>

[Diego A.]

Hi John/Michael,

FOUND THE PROBLEM.

And John, I'm sure you'll be glad to know it's not a bug in jQuery.

I compress (remove white space and pointless concatinations) and re-
pack my scripts into one file with jQuery and all the plugins I use.
This error happened when I compressed and re-packed the
'packed' (compressed) version of jQuery - ie.: compressed it twice.

In the process,
document.write("<\/
script>");

Became...
document.write("<\/
script>");

I just played around with my JS compressor and I've got it working
now.

Hope this helps anyone who has the same problem.

A couple of more notes on this.

1) Instead of attaching the event to the document, you could attach it to
the a specific parent element (i.e. $("ol.icons") instead of $(document).)
This would obviously save some processing.

2) The other benefit of this method, is that you won't need to "reattach"
the behavior if you replace the inner contents of "ol.icons". This means you
can repopulate the images with a different subset loaded dynamically,
without having to re-parse the elements on each dynamic load.

I thought that too! :) I'm using it in a plugin I'm writing to make
the output customizable. Also I think that it is much more readable
and easy to maintain a template than a function with a lot of + and
vars to build a complex html structure.

The code came entirely from Ext - the brilliant work was made by Jack
Slocum. As I've used it for a while, I missed the template class a lot
when I moved to jQuery. And so I adapted/simplified it to use on
plugins.

Quite frankly, searching over thousands of elements is just slow. Generally
always has been. It's not so much a jQuery issue as parsing thousands of DOM
elements generally is a performance hog.

As already stated by someone else, I'd recommend trying to simplify the
selector as much as possible. I'd probably give each anchor tag a class that
indicates it's for an icon:

var icons = $('ol.icons a.icon');

This will do a little less work.

However, you're best option for speed may to be to just add a onmouseclick
event to the document and then just have that event handler look to see if
you click on a a.icon element.

This prevents needing to parse through the DOM looking for thousands of
matches, and instead you just do some parsing on each mouse click. You could
also even just check the  element directly. 

For example:

$(document).bind("click", function (e){
// get the target element (srcElement for IE, originalTarget for
W3C)
var el = e.srcElement || e.originalTarget;
if( el.tagName == "A" && el.className == "icon" ){
alert("Hey, I'm an a.icon element!!!");
return false;
}
});

The above code will monitor each mouse click event. If you click on the an
 tag with a class name of "icon", the alert() will be triggered.

This code allow you to very efficient add the behavior you're looking
for--without having attach the behavior to each and every  tag. 

This should be extremely fast and efficient...

[jQuery] Getting ThickBox to work with other libraries

[[EMAIL PROTECTED]]

Hi guys.

I have developed a web app and am making various AJAX popups using
Thickbox. However some of these popups use other JS libraries (eg:
scriptaculous). I have tried to implement the suggestions in this
link: http://docs.jquery.com/Using_jQuery_with_Other_Libraries  but
didn't help, I tried all three ways and had no success.

So basically my webpage has a few links and on one of the links once
its clicked it opens a popup (meant to) and there you can use
scriptaculous to edit some text. Now if I open the page with the
scriptaculuos stuff in directly (IE: not via popup) it all works fine.
If I try open it with the link it gives me a blank page and shows the
page is still loading but it never does, it also gives me JS errors
such as:

jQuery is not defined, AjaX is not defined etc...

Here is a brief peice of code to try clairify the situation:

">
">






jQuery.noConflict();


the paths are all correct but there is some sort of conflict that
doesnt allow the page to load.

Please can anyone advise as to what the problem is and how to solve
it, anything would be welcome as its getting critical .

Thanks in advance.

[jQuery] Re: massive jquery memory leak in firefox 2.x: load() or empty()?

[[EMAIL PROTECTED]]

If I reload, close the Tab or navigate somewhere else, it is not given
back. If I close the Browser and Re-open it, yes.

I checked out some tweaks from a firefox memory leak discussion
( http://www.freerepublic.com/focus/f-bloggers/1327586/posts ) but
nothing works so far. I'm using Process Explorer to monitor Private
Bytes. I disabled firebug and webdeveloper toolbar.

This is about 0.5 to 1mb per operation and the requested data is about
50kb.

Firefox is taking so much memory and the more it takes the longer the
scripts need to execute rendering the whole javscript/jQuery stuff
useless. I mean how do you handle that? It's just simply not working
any longer after a hundred clicks. Even Reload gives me Messageboxes
telling me that a script is taking long and wether I want to stop,
debug or continue that. Is there something like freeing jQuery
objects, resetting something or similar? Resetting the whole
javascript engine maybe? I only need that for Firefox.

Thanks for your help so far!

[jQuery] Re: Improved timePicker, time/datePicker demo

[Anders]

It does have more features than mine (although I have added scrolling
to the entered time). It also uses another plugin (below) I did for
positioning, so there is no requirement to have the dimensions plugin.


I didn't know you had continued to develop the list version (which
I've been calling "original"), must have missed that (or you put it up
recently). I wouldn't feel bad if it was made into one version again,
as much of my work is based around your code anyway. Bright future for
timePickers it seems!

[jQuery] .load issue with IE7

[JimD]

Ok so I have payment page.  When the page loads I fill in a list of
payments within a div using .load, and within the page being loaded in
the div, I have another .load that feeds in a total box. This all
works great in FF2, but for some reason in IE7 the paybox doesnt not
display.

So in the main page I load the list page using .load like so and it
works fine in both IE7 and FF2.


$(document).ready(function(){
   $("div#payments").load('account_rec_load.html',function(){
   return false;
   });
});


Then in the 'account_rec_load.html' page I have a similiar load
function that just loads in a totals box using .load as well. This
works in FF but not IE7. I'm assuming its because the ajax loaded page
isnt actually being seen as loaded in IE7? Sorry Im not quite the
javascript guru. Any ideas why IE7 is treating this differently.

$(document).ready(function(){
   $("div#paytotal").load("payment_total_load.html",function(){
   return false;
   });
});

});


my markup:

   No
   


when I output 'rank' it keeps giving me -1.

I tried jQuery(this).parent('p') or jQuery(this).parent('p')[0] but no luck.
I dont get it because my debug says that it is a "object
HTMLParagraphElement" and if I ask the html() then the content is the right
one.

What I am missing ?
