Hi Rene,
I've never quite understood the benefits to the plugin approach, when
you can simply create an object that uses jquery.
(I've wondered about this before on the list, but so far no one has
enlightened me.)
function Animator(container) {
this.jC = container; // this is a jquery
looks good. pointX is a global variable and can be accessed by both
functions. What's the problem?

Calling a $.get() on each page change click kind of defeats the point
of doing client-side paging. It will be basically be as slow as
reloading an entire new page (and you have to add some UI to show that
the page is 'loading...).

Try creating a test page with only the js code needed for the tabs.
As for keeping content hidden during loading, I like to use a css
class called hidden.
/* css */
.hidden { display: none; }
/* html */

Much like how jquery keeps the javascript out of the HTML, it's so
much cleaner to keep PHP out of the HTML as well.
Have a look at the Smarty templating system for PHP. It's awesome.

You might find it easier to simply create objects that use jquery,
instead of writing a jquery plugin.
The biggest advantage is that you actually have a normal instance of
an object. You can pass this instance to other objects, call other

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

so people don't spend time responding to already-answered questions?

good tips so far.
I just wanted to add that using classes and ids works well.

It sounds like your friend needs a better screen magnifier. Increasing
just the font size in the browser is a hack.

you can't return a value from an anonymous function!
think about it: you call $.get() and pass in an anon function as a

$.get() returns basically immediately, and then sometime later (much
later) your anon function will be called.
Where does the return value of anon go? Nowhere.

This isn't specific to jQuery. One way...
var x = '{a:123,b:456}'; // json
eval('var z='+x);
z is now an object. z.a = 123, etc.

You can profile javascript with firebug and see total calls for
different approaches and how long they take.
That said, $('#id') is fast, since it is basically getElementById() a
native javascript method. However, if you call $('#id') 100x, you'll
see that it's faster to cache it in a variable.
Yes, great screencast. (I think i learned a little portuguese too.)
A question about literal objects - is it fundamentally different than
using prototype?
//
// example 1: literal obj
//
var Counter = {
container = $('#counter');
start: 1,
init: function() { container.val(start); }
}
Looks to me like you're missing a closing bracket, so your 2nd click
method ($('a#enviar_jqm_trigger') is encapsulated in the first ($
('a#corregir_jqm_trigger'). No?

First, I would try to optimize your code. Make sure that you are
calling as few $() methods as possible.
(e.g. build strings and set with html() instead of repeatedly calling
append() or after(). Firebug can also help you profile.)
But if your code is as tight as it can be, then why not a
Firebug shows you the HTML as it understands it. So if it doesn't look
right, it usually means you are creating invalid HTML.
The biggest problem with your example, is that you are calling
append() repeatedly, and I don't think the elements are being inserted
where you expect. What type of
Couple of thoughts:
1) $.each() is not for moving through an array. (is for doing
something to each matched DOM element) try: for(item in _json)
{ alert('item:'+item);}
2) try defining your global as an object. e.g. var _json = {};

A simple work around is to append a character to the id to keep them
unique. But also, store the ID in the parent TR.
e.g.
tr id=u4
td class=empBob Smith/td

/tr
Then you can get the id with
$('div.1-Jan-2008').click(function() {
