I use MooTools, and I need to find the element which has both classes "a" and "b" (the innermost div in my example below).
The HTML structure is:
<div class="a"> <div class="otherclass"> <div class="b"></div> </div> </...

What about
$$('div.a div.b')
or
$$("div.a").getElements("div.b");
var divsB = $$("div.a div.b");
http://mootools.net/shell/jfnWK/ - selects the first one but not the second as it's not a child of a div.a .

I want to write some javascript classes which extend DOM nodes (so that I can then insert instances of my class directly into the DOM), but am having difficulty finding out which class/prototype I should inherit from.
eg

At least, it enables me to access the extended object properties via the DOM element from DOM element, you need to have access to that element's prototype.
You can simply add new functions to the DOM prototypes, eg that works...

In Javascript, you can extend existing classes by using its prototype object:
String.prototype.getFirstLetter = function() { return this[0]; };
Is it possible to use this method to extend DOM elements?

Plus re-extending every new.
However, this does (by "anything" I mean native DOM objects) - that will only lead to bad things.
() { return this.id; };
you can extend the DOM by using the Element's prototype.

In javascript, what are the pro's and con's of encoding an onclick event in the DOM and in the HTML itself?
Which, if either, is better than the other and why?

It is even better to use proper DOM events ( addEventListener and attachEvent ) rather than.
Attaching events to an CSS-style ID (or classes), as Jquery does so says.
Everything down all at once.

Can I test my client side GWT code without GWTTestCase? I've heard somewhere (I think it was one of the Google IO 2009 conferences) that they were successfully testing their code with a fake DOM, in the JVM and not in Javascript with the DOM. That would...

Any code that requires the DOM should go in your View classes/Presenter pattern and abstract away all the DOM-accessing code to the 'View' portion.

When using $("#xxx") I guess under the hoods jQuery uses getElementById .
What about $(".xxx") does it scan the whole DOM every time?

Many browsers do not support getElementsByClassName as a native DOM function, so jQuery has to do the work itself by checking each element's classes.

Example:
$("#a.toggle").click(function(e) { var target = $(this); $.ajax({ url: '/changeItem.php', dataType: 'json', type: 'POST', success: function(data,text) { if(data.error=='') { if(target.hasClass('class1')) {... .
You can just store it in a variable.

Hey all,
I was just wondering if there is a clean implementation to getting elements before appending them to the DOM.
Example (w/ jQuery):
var html = "<div class = 'test'><div class = 'innertest'>Hello!</div></div>"; var innerDiv...

Some of the examples do involve the DOM, but they really give a feel for the flexibility of the core.

The id attribute can be used by a JavaScript (via the HTML DOM) or by
CSS to make changes or style.
