MooTools 1.2 Class Template

By  on  

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'
		});
	}

    LightFace:  Facebook Lightbox for MooTools

    One of the web components I've always loved has been Facebook's modal dialog.  This "lightbox" isn't like others:  no dark overlay, no obnoxious animating to size, and it doesn't try to do "too much."  With Facebook's dialog in mind, I've created LightFace:  a Facebook lightbox...

    Create a Simple Slideshow Using MooTools

    One excellent way to add dynamism to any website is to implement a slideshow featuring images or sliding content. Of course there are numerous slideshow plugins available but many of them can be overkill if you want to do simple slideshow without controls or events.

  1. Great reference point, thanks!

  2. 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.

  3. 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 ;)

  4. @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!

  5. 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…

  6. An extra nice post, David. Thanks! (It’s Stumble time!)

  7. Very nice snippet

  8. What about add Extends?

  9. @Imzyos: I don’t extend other classes much.

  10. @Crispjin: Instead of e.addEvent('mouseenter',function() { });, you may want to consider adding a mouseenter event to the class and replace the above with this.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.

  15. 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
