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.
Implied variable typing (JavaScript)
You can associate a variable with a data type to document your code and direct content assist.

- 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.
  - @Functions (JavaScript)
    @Functions emulate their counterparts in Notes®.

  - 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.

Implied variable typing (JavaScript)

You can associate a variable with a data type to document your code and direct content assist.

The syntax for variable typing is as follows:

variablename:datatype

The following code from a computed field implies that db is a NotesDatabase object:

var db:NotesDatabase = session.getCurrentDatabase();
return db.getFileName()

The implied data type has no effect at run time. If your code states db:Foo or db:NotesStream, db is still treated as a NotesDatabase object at run time. The return value of session.getCurrentDatabase() determines the type.

If no data type association is provided, content assist determines a type from the context, if possible. If a data type association is provided, content assist uses the specified type. In most cases, content assist works the same whether or not an association is provided. Occasionally, specification of the data type provides necessary direction.

Note: Take care to specify the correct data type as an association. If you specify the wrong data type, content assist uses that wrong data type.
