Re: Accessible CSS / JS Bootstrap framework

Oh, I get it. Such as adding the class 'modal' to a link, which 
automatically configures a modal to open when activated.

This is actually very easy to setup using AccDC if you wish.

For example, to do this for an accessible calendar picker, all you would 
need is the following script to run on any given page.

$A.bind(window, 'load', function(){
// Parse all A tags that include the class 'calendarPicker'
$A.query('a.calendarPicker', function(i, o){
// Set a calendar picker and bind it with the associated Input tag
setCalendar(o.id, o, $A.query('input[name=' + o.id + ']')[0]);
});
});

Which could be part of a global script file and run as a general parser on 
all pages.

Then, devs need only use the following HTML syntax to make accessible date 
pickers.

<input title="Set departure date" type="text" name="departureDate" />
<a href="#" class="calendarPicker" id="departureDate"> Departure Calendar 
</a>

<input title="Set return date" type="text" name="returnDate" />
<a href="#" class="calendarPicker" id="returnDate"> Return Calendar </a>

So basically, every A tag with a class of 'calendarPicker' is parsed, then 
the ID of that A tag is matched with the Name attribute of the associated 
Input tag in order to store date strings when returned.

Then, simply add a general calendar class to the global style sheet, and you 
will have global calendar pickers that are fully accessible, and styled to 
look like whatever you like.

Also, since the calendar picker is programmed to render each calendar view 
as an AccDC Object, the ID for this object is associated with the ID of the 
triggering element as well. Meaning that you can apply any of the AccDC Core 
API methods on the object at runtime if desired, like so:
$A.reg.returnDate.close();
$A.reg.returnDate.open();
etc. There's over a hundred different methods and properties that can be 
directly applied in this manner.

You can do the same thing with most of the AccDC module types as well, such 
as modals, banners, tooltips, popups, menus, tree controls, sliders, 
accordions, carousels, and slideshows.

In the case of the modals/banners/tooltips/popups, these are declared as 
AccDC Objects in the archive, but these could easily be converted to do the 
same by wrapping an invocation statement around each, and assigning 
variables to control the ID property and resource path assignment.

If you would like to use AccDC, and need any help, just let me know.
