JavaScript and XPages reference
This reference describes the JavaScript™ language elements, Application Programming Interfaces (APIs), and other artifacts that you need to create scripts, plus the XPages simple actions.
- JavaScript™ language elements (JavaScript)
  The JavaScript™ language elements are based on the ECMAScript Language Specification Standard ECMA-262 (see http://www.ecma-international.org/publications/standards/Ecma-262.htm). The JavaScript described here applies to the server-side interpreter. Client-side scripts are interpreted by the browser.
- Simple actions (JavaScript)
  A simple action performs a pre-programmed activity that can be modified by arguments.
- Global objects and functions (JavaScript™)
  Global objects provide entry points to server-side scripts. Entering the name of a global object instantiates it.
  - applicationScope (JavaScript)
    Allows you to share values across pages for the duration of an application.
  - bluemixContext (JavaScript)
    Used to help in the development of XPages applications running on Bluemix. The bluemixContext global object is based on the Java™ class com.ibm.xsp.bluemix.util.context.BluemixContext and provides methods to retrieve information from the XPages runtime and connection information from any bound XPages NoSQL Database service.
  - requestScope (JavaScript)
    Allows you to share values across pages for the duration of a request.
  - sessionScope (JavaScript)
    Allows you to share values across pages for the duration of a session.
  - getComponent (Global objects and functions - JavaScript)
    Gets the base object for a UI component.
  - getLabelFor (Global objects and functions - JavaScript)
    Gets the base object for the label associated with a UI component.
- DOM (JavaScript)
  Represents a document in XML Document Object Model format.
- Domino®
  This library provides access to the IBM® Domino® back-end.
- Runtime (JavaScript)
  The Runtime library contains classes that provide useful methods for globalization.
- Standard (JavaScript)
  The Standard library contains classes for manipulating data of different types and performing common operations.
- XSP (JavaScript™)
  The XSP library contains classes that access the browser context.

getLabelFor (Global objects and functions - JavaScript)
