.empty and .html looks in every node that it removes/replaces and

I think you are looking to namespace the event.
$(selector).live('click.ns');
$(selector).die('click.ns');
The die() will only remove the click that occurs with that namespace
and leave other click events alone.

Just a style suggest, but reverse your usage of quotes:
$('#searchresult').html(' ');
instead of
$('#searchresult').html(" ");
It sounds like John is saying that
e.preventDefault() will prevent the default event from occuring and
e.stopPropogation() will prevent the event from bubbling up and
return false will do both, so
If you only want to stop the default but allow propogation or vice

.bind enables you to pass variables into the callback function via the
e.data attribute in the event.
$(document).bind('click', {'foo': 'bar'}, function(e) {
console.log(e.data.foo);
});
Can't do that with the .click shortcut.

Find more on selectors at:
http://docs.jquery.com/Selectors
and more on the .text() & .html() at:
http://docs.jquery.com/
instead of obj['name'] use obj.name They both work, but the first
makes it look like a hash when you are really using properties of an

While not what you were asking, remember that you can chain.

You could also put the .click events inside a document.ready(). Then

The problem is this:
$(".block a").mouseover(function(){
$(".block a").animate({
$('.block a') gets every instance of an a element with class block.
So when you do the .animate on it, you are animating every element.
Instead, you mean.
$(".block a").mouseover(function(){
$(this).
Because it puts it in the javascript and lets you easily manipulate it
with javascript. If you get html back from the server, it's more
difficult to manipulate.
$.getJson('path/to/url', function(data) {
var tableHTML = '';
$.each(data.aaData, function() {
tableHTML += '' + this

No, JSON is the correct route. If you are using ajax to retrieve
json, then you can pull the json into a javascript object
immediately. If you are using PHP to generate pages, then you can
print out the JSON object as a string directly into javascript and
create javascript objects that way. jQu

What this is doing:
jQuery('.choix1').click(function(){
jQuery('#quest1').hide();
});
is looping through every element on the page with a class of 'choix1',
so you could either change all of the elements you want to loop though
classes to choix and then do
jQuery('.choix').click(function(){
Where does this error come from?
[cycle] terminating; zero elements found by selector
You can see it when the page loads on the firebug console, but it
doesn't give a file name or line number. it may be that since you
aren't getting any elements back, IE is messing up because you are
trying to

$('.numberPages').change(function() {
$('p.foo').hide().eq($(this).find(':selected').text()-1).show();
});
You can still use name, just change your selector to
$('[name=div1]')
Also, when writing out html in string, put them between single quotes
and the html in double quotes so you can do this:
var htmlText = 'Hola!!';
instead of
var htmlText = 'Hola!!';

Why do you have the [] characters in the name of the elements? That

Another options is to give the dealAmount inputs a new attribute with
a value of an incrementing numbers, foo="0" say. As long as the post
amounts are in the same order you could:
$('[name=dealAmount'
Long answer:
Check out the section on Traversing in the jquery documentation on the
site. Lots of good examples and documentation on there.

Simple answer:
DOM nodes are created by just writing the html in side of the jQuery

is equivalent to

Using console.log and firebug will show you what everything is.
