As much as Java is used throughout Liferay’s back-end data layer, JavaScript is used throughout its presentation layer. Liferay uses JavaScript to implement responsive control logic and provide powerful UI components, and the scripts leverage Liferay’s component-rich JavaScript library AlloyUI.
Liferay’s JavaScript follows the Module Pattern to encapsulate data and
functionality. It makes available its modules via the Liferay global object.
The Liferay object is loaded automatically at runtime and is available
throughout the portal, its theme, and all portal plugins. It includes a myriad
of sub-objects that are chock-full of useful methods. Read on to find out more
how you can take advantage of Liferay’s JavaScript objects.
