MooTools 1.2 Class Template
Starting a MooTools class can be difficult if you haven't created one before. Here's a template you can copy, paste, and use to create your MooTools classes.
MooTools 1.2 Class Template
var yourClass = new Class({
//implements
Implements: [Options],
//options
options: {
yourOption: ''
},
//initialization
initialize: function(options) {
//set options
this.setOptions(options);
},
//a method that does whatever you want
yourMethod: function() {
}
});
MooTools 1.2 Class Usage Template
//once the DOM is ready
window.addEvent('domready', function() {
var yourInstance = new yourClass({
yourOption: 'yourValue'
});
}

One major problem with creating UI components with the MooTools JavaScript framework is that there isn't a great way of allowing customization of template and ease of node creation. As of today, there are two ways of creating:

![Detect DOM Node Insertions with JavaScript and CSS Animations]()
I work with an awesome cast of developers at Mozilla, and one of them in Daniel Buchner. Daniel's shared with me an awesome strategy for detecting when nodes have been injected into a parent node without using the deprecated DOM Events API.
![Resize an Image Using Canvas, Drag and Drop and the File API]()
Recently I was asked to create a user interface that allows someone to upload an image
to a server (among other things) so that it could be used in the various web sites my
company provides to its clients. Normally this would be an easy task—create a...
![CSS Gradients]()
With CSS border-radius, I showed you how CSS can bridge the gap between design and development by adding rounded corners to elements. CSS gradients are another step in that direction. Now that CSS gradients are supported in Internet Explorer 8+, Firefox, Safari, and Chrome...
Great reference point, thanks!
This is something I’ve been curious about for a while with MooTools. What would you use a class for? What determines whether you use a Class or just a function?
I’m really trying to learn best practices for coding with MooTools and other libraries but I haven’t really found an all encompassing resource…all though this site is quickly becoming a favorite.
I’ve been doing the same thing!
@Seth, the best explanation I’ve heard is that classes help make your code more readable, reusable, and less complex. That’s the short answer ;)
@Seth: I use classes when I’m creating functionality with options. I also use classes so I can reference objects. It does keep the code cleaner too!
I use classes when I want to reuse the code with other occasions – in same project, or other – with different options
I use functions when I do more specific tasks, or more simple that a class would be just overhead…
An extra nice post, David. Thanks! (It’s Stumble time!)
Very nice snippet
What about add Extends?
@Imzyos: I don’t extend other classes much.
@Crispjin: Instead of
e.addEvent('mouseenter',function() { });, you may want to consider adding amouseenterevent to the class and replace the above withthis.fireEvent('mouseenter');.I’m not very familiar with the JavaScript/moo syntax so I’m still struggling with your suggestion with the this.fireEvent
How do I implement this? Where to I leave the “e” variable witch points to the element I would like to change the opacity? The mootools docs couldn’t give me a right example…
var fadeButtons = new Class({ Implements: [Options], options: { maxopacity: 1, minopacity: 0 }, initialize: function(options){ this.setOptions(options), this.start() }, //start the button events start: function(){ var list = $$('#buttons div img'); list.each(function(e) { this.e.fireEvent('mouseenter'); //OLD HABBITS /*e.addEvent('mouseenter', function(){ e.fade(this.options.minopacity); }); e.addEvent('mouseleave', function(){ e.fade(this.options.maxopacity); });*/ }); }, });Could you give me a kick in the right direction? Thanks anyway!

Thanks for this. For some reason I’ve been using it quite a lot. Simple things are usually best!
One thing I noticed is that Dom Ready is missing ); at the end. So you could add that so it does not confuse newcomers with errors if they use this.
I have been using mootools for a little bit, and I really like it.
Thanks for the tutorials, they’re great… Keep them coming.

Buensimo el ejemplo, sin embargo los métodos no se disparan a menos que agregues
this.fireEvent('yourMethod');donde"yourMethod"es el nombre de tu evento.Ejemplo.-
show: function() { alert('hacer algo'); /*al final de la instrucción*/ this.fireEvent('show'); },Esto es útil cuando quieres agregar codigo personalizado al ejecutar dicho evento.
Hi,
This is the tutorial what I am looking for.
Before some days I have tried to contact you regarding this point. but no reply from your side.
But after all thanks for this post.
Thanks
Avi
