Help me get a MacBook Pro!

Hello everyone, I have now released my accordion script and its better than any other one out there! That's right I said it. I will be releasing a few more of my scripts in the weeks to come. In the meantime though help me get a MacBook Pro so I have a mac to test on! Anything you could throw my way would be appreciated, I will also give back in my forums, so no worries, I give back even more!

 

 

Why another Accordion?

Uhm... There wasn't one, well not a good one.

Haha! Like there was one. Well there was, but only for Rico and a bloated one by mootools, that's right I said bloated, live with it. For some reason there wasn't one for scriptaculous but now there is. The why is pretty simple, just like every other library, I had a need for it. Hope you can get some use out of it.

Oh, by the way, not only does this script handle vertical accordions, but horizontal as well!

A Horizontal Accordion! (Nested)

Oh yeah, just a few options... BAM Horizontal!

Oh and... help me with a MacBook Pro?

How to Use

Include the files

You need to include accordion.js but it requires prototype.js and effects.js (like I said this is for scriptaculous!). As long as you are using at least the latest stable builds you are fine.

<script type="text/javascript" src="javascript/prototype.js"></script>
<script type="text/javascript" src="javascript/effects.js"></script>
<script type="text/javascript" src="javascript/accordion.js"></script>

The Markup

Pretty much anything will work, so its really up to you. The presentation is up to you (see the source of this page for some examples). Ideally you should probably use header tags with div's containing the content as this would be best symantically speaking and for seo. Below is a basic example.

<h2 class="accordion_toggle">Title Bar</h2>
<div class="accordion_content">...</div>
...
...
...
<h2 class="accordion_toggle">Title Bar</h2>
<div class="accordion_content">...</div>

The important thing here is that it need to be the title element then the content element and so on, nothing in between, just like every other accordion.

The Options

Not many options, but all you need to make this thing do anything you may require!

// The speed of the accordion
resizeSpeed : 8,
// The classnames to look for
classNames : {
	// The standard class for the title bar
    toggle : 'accordion_toggle',
    // The class used for the active state of the title bar
    toggleActive : 'accordion_toggle_active',
    // The class used to find the content
    content : 'accordion_content'
},
// If you don't want the accordion to stretch to fit 
// its content, set a value here, handy for horixontal examples.
defaultSize : {
    height : null,
    width : null
},
// The direction of the accordion
direction : 'vertical',
// Should the accordion activate on click or say on mouseover? (apple.com)
onEvent : 'click'

Now these are the default options set automatically, so let's now take a look on how to create an accordion and change those options.

The Javascript

Below is how I created the two accordions you see on this page, one vertical, one horizontal with a specified width.

// General Syntax
new accordion('container-selector', options);

// Horizontal example
var horizontalAccordion = new accordion('#top_container', {
    classNames : {
        toggle : 'horizontal_accordion_toggle',
        toggleActive : 'horizontal_accordion_toggle_active',
        content : 'horizontal_accordion_content'
    },
    defaultSize : {
        width : 525
    },
    direction : 'horizontal'
});

// Vertical Accordion
var verticalAccordion = new accordion('#bottom_container');

Ok, so now we know how to do the markup, hopefully you got creative with the css and looked at the source of this page to get started, and not you know how make an accordion. What if you want to use javascript to open a slide on load or at any time... here is how.

// Let's create it
var verticalAccordion = new accordion('#bottom_container');

// Now lets open the first slide
verticalAccordion.activate($$('#bottom_container .accordion_toggle')[0]);

So we use the selector method from prototype to get the first title bar from the container+classname and we want the first one so we use [0]. Couldn't be easier!

Preload

So let's say you want all your accordions closed on page load but don't want the nasty flash and don't want to sacrifice accessibility.

// Special thanks go out to Will Shaver @ http://primedigit.com/
var verticalAccordions = $$('.accordion_toggle');
verticalAccordions.each(function(accordion) {
    $(accordion.next(0)).setStyle({
        height: '0px'
    });
});
