Overview

Widgets can be included individually (using Figuration’s individual *.js files), or all at once (using figuration.js or the minified figuration.min.js).

Using the compiled JavaScript

Both figuration.js and figuration.min.js contain all widgets in a single file. Include only one.

One Widget per Element

Don’t use multiple widgets on the same element. For example, a button should not both have a tooltip and toggle a modal. Doing so would cause a conflict in functionality and with the ARIA attributes.

Widget Dependencies

Some widgets and CSS components depend on other widgets. If you include widgets individually, make sure to check for these dependencies in the docs. Also note that all widgets depend on jQuery (this means jQuery must be included before the widget files). Figuration is currently only tested/supported on the latest version of jQuery.

Contents

Util

All of Figuration’s widgets depend on util.js and it has to be included alongside the other JS files. If you’re using the compiled (or minified) figuration.js, there is no need to include this—it’s already there.

util.js includes utility functions and a basic helper for transitionEnd events as well as a CSS transition emulator. It’s used by the other plugins to check for CSS transition support and to catch hanging transitions.

Also, some of the widgets use MutationObserver utilities to watch for and respond to DOM changes.

No Conflict

Figuration has opted to not go with a .noConflict mode. Due to crosstalk between some of the widgets, we extended the namespaces by marking all functionalty with CFW or cfw, as in CAST Figuration Widget.

The structure is: CFW_WidgetName for widgets, data.cfw.widgetName for data storage, data-cfw-widgetName-option for data attributes, event.cfw.widgetName for events.

This is to hopefully reduce the chance of conflicting with other frameworks and plugins.

Scoped Initilization

Initializing the widgets in AJAX inserted content can be accomplished easily by calling the $().CFW_Init() function. Widgets set with data attributes on both the specified element, and it’s descendants, will be initialized.

This function that also called at page load using document.body as the initial scope.

$("#myContainer").CFW_Init();
// Where '#myContainer' is the region of new content to initialize the Figuration widgets.

Scoped Dispose

In those cases where you are need to call the dispose method on every Figuration widget for a given region, you can use the $().CFW_Dispose() function. Any widget encountered on the specified element, and it’s descendants, will have their dispose methods invoked.

$("#myContainer").CFW_Dispose();
// Where '#myContainer' is the region to `dispose` of Figuration widgets.

Data Attributes

You can use most Figuration widgets purely through the markup API without writing a single line of JavaScript.

In some situations it may be desirable to turn this functionality off. The data attribute API auto-initialize can be disabled by inserting a global variable in the <head> of the document, before loading the figuration.js, to stop the initial call to $().CFW_Init() from occuring.

<script>var CFW_API = false;</script>

Option Inheritance

When using both data attributes and JavaScript options, the JavaScript options take precendence over any element attributes.

<!-- Override the HTML attribute -->
<button type="button" id="optionOrder0" class="btn" title="ignored title">Show Tooltip</button>
<script>
$('#optionOrder0').CFW_Tooltip({
    title: 'tooltip title',
    container: 'body'
});
</script>

<!-- Override the data attribute -->
<button type="button" id="optionOrder1" class="btn" data-cfw-tootltip-title="ignored title">Show Tooltip</button>
<script>
$('#optionOrder1').CFW_Tooltip({
    title: 'tooltip title',
    container: 'body'
});
</script>

Programmatic API

You can also use all Figuration widgets purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.

$('#myCollapse').CFW_Collapse('hide').removeClass('aClass');

All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a widget with default behavior):

$('#myPop').CFW_Popover();                          // initialized with defaults
$('#myPop').CFW_Popover({ placement: 'bottom' });   // initialized with bottom alignment
$('#myPop').CFW_Popover('show');                    // invokes show method

Each widget also exposes its raw constructor on a Constructor property: $.fn.CFW_Popover.Constructor. If you’d like to get a particular widget instance, retrieve it directly from an element: $('[rel=popover]').data('CFW_Popover').

Events

Figuration provides custom events for most widgets’ unique actions. Generally, these typically come in a before and after form - where the before form (ex. beforeShow) is triggered at the start of an event, and its after form (ex. afterShow) is trigger on the completion of an action.

All before events provide preventDefault functionality. This provides the ability to stop the execution of an action before it starts.

$('#myModal').on('beforeShow.cfw.modal', function(e) {
    if (!data) return e.preventDefault(); // stops modal from being shown
});

Asynchronous Functions and Transitions

All programmatic API methods are asynchronous and returns to the caller once the transition is started but before it ends.

In order to execute an action once the transition is complete, you can listen to the corresponding event.

$('#myCollapse').on('afterShow.cfw.collapse', function(e) {
  // Action to execute once the collapsible area is expanded
})

In addition a method call on a transitioning component will be ignored.

$('#myCollapse').on('afterShow.cfw.carousel', function(e) {
  $('#myCollapse').CFW_Collapse('hide'); // Will hide the collapsible area as soon as the transition for opening the area is finished
})

$('#myCollapse').CFW_Collapse('show'); // Will start opening the collapsible area and returns to the caller
$('#myCollapse').CFW_Collapse('hide'); // ** Will be ignored, as the opening transition has not completed **

No Fallbacks

Figuration’s widgets don’t fallback or degrade gracefully when JavaScript is disabled. If you care about the user experience in this case, use <noscript> to explain the situation (and how to re-enable JavaScript) to your users, and/or add your own custom fallbacks.

Dipose Methods

Every widget has a dispose method that should remove any event listeners and data, as well as nullify any constructed JavaScript variables associated with a given widget. Certain widgets will also remove their dynamically created content or controls from the DOM.

While most likely not needed in everyday use, there may be specific circumstances when this might be useful. For example, if you are doing large amounts of dynamic content, in order to help with memory garbage collection, it might be beneficial to call the dispose on a widget before you remove the content from the DOM.

Accessibility

Best Practices Approach

Figuration attempts to take a best practices approach to providing as much accessibility and usability to the widgets.

All widgets take into account keyboard, mouse, and touch navigation methods where possible to provide usability across a wide array of platforms. In come cases functionality is forced on or off depending on the presence of touch devices.

Automatic Attribute Generation

To provide screen readers with high levels of accessibility the widgets will automatically generate the neccessary id, tabindex, role, and aria-* attributes that best fit the functionality. If an id is already provided the widgets will keep the existing one and use it accordingly.

This was done to alleviate the complexity of any generated source code—the data api adds enough on its own—and remove concerns over which attributes are needed for the developers and content authors.

role Attributes on Container Items

Container items at a higher level from a widget component might need to have a role specificied. These are not handled by the widget code and will need to be used as needed.
