FormCalc
is a simple yet powerful calculation language modeled on common spreadsheet
software. Its purpose is to facilitate fast and efficient form design without
requiring a knowledge of traditional scripting techniques or languages. Using
several of the built-in functions, inexperienced FormCalc users
can quickly create forms that save users from performing time-consuming
calculations, validations, and other verifications. This way, you
can create a basic set of rules for the form design that allows
the resulting form to react according to the data it comes into
contact with.
Within Designer, FormCalc is the default scripting language in
all scripting locations with JavaScript as the alternative. For
information on setting your default scripting language, see
Configuring Designer for Scripting
.
Important:
If you are developing forms for
use with a server-based process (for example, using Foms), with
the intent of rendering your forms in HTML, you should develop your
calculations and scripts in JavaScript. FormCalc calculations are
not valid in HTML browsers, and are removed prior to the form being
rendered in HTML.
FormCalc treats each new line in the Script Editor as a new expression
to evaluate.
