Welcome
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.
Top-level functions (JavaScript)
Top-level functions are not associated with an object. In the ECMA specification, these functions are properties and methods of the global object.
isNaN (JavaScript)
Determines whether the result of a string parsed by parseInt or parseFloat is a valid number.

- 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.
  - Statements (JavaScript)
    JavaScript™ statements consist of keywords and syntax.
  - Operators (JavaScript)
  - Top-level functions (JavaScript)
    Top-level functions are not associated with an object. In the ECMA specification, these functions are properties and methods of the global object.
    - _dump (JavaScript)
      Prints a string representation of an object to the log file.
    - eval (JavaScript)
      Evaluates an expression or statements.
    - isNaN (JavaScript)
      Determines whether the result of a string parsed by parseInt or parseFloat is a valid number.
    - parseFloat (JavaScript)
      Parses a string and returns a floating point number.
    - parseInt (JavaScript)
      Parses a string and returns an integer of the specified radix or base.
    - print (JavaScript)
      Prints a string to the log file.
  - @Functions (JavaScript)
    @Functions emulate their counterparts in Notes®.
  - Implied variable typing (JavaScript)
    You can associate a variable with a data type to document your code and direct content assist.
  - Embedding Java™ in JavaScript™
    Java™ code can be embedded directly into JavaScript™ code.
- 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.
- DOM (JavaScript)
  Represents a document in XML Document Object Model format.
- Domino®
  This library provides access to the HCL 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.
HCL Domino C API
The documentation for HCL Domino C API is included in HCL's open source Git repositories.
