Oracle Apex and jQuery integration from the Box

jQuery has been included by default in Oracle APEX applications since the advent of dynamic actions. The application builder provided wizards to define event handlers that interact with page components.

In addition to dynamic actions, Oracle APEX provides the ability to utilize other jQuery features declaratively. For instance, date pickers and autocomplete items use the jQuery framework. Many types of APEX plug-ins also use the jQuery library to function.

APEX also provides a number of JavaScript APIs that wrap interactions that seem specific to APEX, or emulate SQL style functions, such as $nvl() or $v(). Details on these can be found in the APEX API reference documentation.

To keep the amount of JavaScript required to service the typical web page low, a number of jQuery functions aren’t included by default.

APEX does include the necessary libraries in the /images folder. To include support for slider bars, type the following in the page attribute JavaScript File URLs:

#IMAGE_PREFIX#libraries/jquery-ui/1.8/ui/minified/jquery.ui.slider.min.js

You can even include the jQuery core library in APEX 3.x.

All this means you can start utilizing jQuery functionality straight away in versions APEX 4.x and up.

Oracle developers shouldn’t find themselves in a chasm when exploring the use of jQuery. A basic jQuery command breaks down into two components, the first of which can be equated to the WHERE clause of a SQL statement. The second is the function that applies the relevant effect or triggers a process.

Document manipulation and event handling are not only marquee components of the jQuery framework, but are also fundamental to supporting effects and animations, AJAX, and data communication using the JSON format. jQuery also provides extensibility through plug-ins.
