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.
