DesignCreate a Script Data Source

By using a Script data source, you can specify the data value or alter the visual properties of a field based on the result of a JavaScript. For information about scripting syntax and capabilities specific to Loftware Enterprise SP, see Scripting.

Loftware Enterprise™ SP uses the Rhino JavaScript engine for Script data sources and supports both the Rhino and Nashorn JavaScript engines for use in scripts in business rules. Rhino is an open source JavaScript engine maintained by the Mozilla Foundation, and Nashorn is an open source JavaScript engine maintained by Oracle. These engines enable you to parse, compile, and run JavaScript statements.

Note: JavaScript versions 1.3 and later conform to the Standard ECMA-262 ECMAScript Language Specification. For more about this specification, see "Scripting, Java, and XML" in External Links.
