The function restricts the allowed input characters of a text field to numbers and formats the
resulting string as specified. A number format is applied via two separate JavaScript actions in PDF
which are automatically created and added to the text field.
The same formats can also be applied manually by creating two JavaScript actions: one for the
OnKeyStroke event, and one for the OnFormat event of the text field. See AddActionToObj() for a
description of the events.
DynaPDF uses the JavaScript functions AFNumber_Keystroke() / AFNumber_Format() to apply a
number format. The functions are described in the JavaScript scripting reference that is available at
