Joomla! Documentation™

The Joomla! CMS includes a number of Javascript Frameworks. This means instead of including your own Javascript code, you may use these pre-existing Javascript libraries of functions. Frameworks are loaded using calls to static methods in the JHtml class.

Twitter_Bootstrap_Javascript_Framework

To enable the bootstrap framework, call JHtml::_('bootstrap.framework'). This will automatically enable the Jquery framework in noConflict mode[ie accessed via jQuery. instead of $.] The bootstrap libary included is version 2.1.0 and is located at media/jui/bootstrap.js It includes methods to initialize the Bootstrap alert, button, carousel, collapse, dropdown, modal, tooltip, popover, scrollspy, tab, typeahead, and affix plugins.

NOTE: there is a known incompatibility between bootstrap-button and jquery-ui-button. Using both on the same page can result in conflicts. See https://gist.github.com/4177778 for a possible workaround.

JQuery_Javascript_Framework

In order to load JQuery, use JHtml::_('jquery.framework'); This will load the Jquery version 1.8.1 library in no conflict mode. This means it is accessed via the jQuery namespace, not through $. To load it in normal mode, call JHtml::_('jquery.framework', false);

JQuery_UI_Framework

The JUX libraries include the core jQuery UI code plus Widget, Mouse, Position, and Sortable. In order to load the core call: JHtml::_('jquery.ui'); This will load the jquery-ui.core.js library containing Jquery UI version 1.8.23 including Widget, Mouse, and Position. Enabling jQuery UI automatically enables JQuery in no conflict mode.

To add the Sortable library, use JHtml::_('jquery.ui', array('sortable'); This will automatically include the core JQuery UI library and the JQuery library.

To enable both jQuery UI core and sortable in a single call, use JHtml::_('jquery.ui' array('core', 'sortable');.

At this time, the CMS is only shipped with jQuery UI Core and Sortable.

To include other jQuery plugins, including jQuery UI plugins, you will need to call JHtml::_('script') along with the appropriate parameters in order to include them - or add your own JHtml library to enable autoloading.

Mootools_Javascript_Framework

It is assumed that this framework is depreciated and may be removed in future versions Loads the mootools libraries from system/js. JHtml::_('behavior.framework', $type) where $type defines which library Core: mootools-core.js, version 1.4.5 More: mootools-more.js, version 1.4.0.1, enabling more automatically enables core

Joomla!_Javascript_Framework

Many of the Joomla libraries require the Mootools framework, it is assumed that these will be migrated to the Bootstrap framework in some future version These javascript libraries can be located under the media/system/js folder and include:

caption.js, to enable use JHtml::_('behavior.caption', $selector) This will apply the caption functions to all elements of the DOM who have the css class $selector. Default selector class is img.caption. In order to apply the caption function to multiple classes, simple make multiple calls to JHtml::_('behavior.caption', $selector). The library will only be loaded once, but it will be applied to all classes.

tooltip.js, to enable use JHtml::_('behavior.tooltip', $selector, $params) For all DOM objects with class $selector, an onhover tooltip will be created based on $params. Default selector is class 'hasTip' Loading this framework will also load the Mootools framework.

combobox.js, to enable use JHtml::_('behavior.combobox') Creates a combobox effect. Loading this framework will also load the Mootools framework.

validate.js, to enable use JHtml::_('behavior.formvalidation') Enabled form validation based on rules defined by the form fields. Loading this framework will also load the Mootools framework.

switcher.js, to enable use JHtml::_('behavior.switcher') Is used internally and unlikely to be useful to other components. When enabled, it also enables the Mootools framework.
