FormatType
The syntax kind of a text field's value format (FieldFormat). A text widget's format prop is null for a plain text field, or { type, format }, where type is a FormatType member telling how to interpret the format string. Set it with useSetWidgetProps; a multiline field ignores its format. See Working with forms for the usage.
| Member | Value | The format string |
|---|---|---|
DateTime | 'datetime' | An Acrobat date format string, such as mm/dd/yyyy or h:MM tt. Covers date, time, and datetime fields: all three share the syntax. |
PDF has no date or time field types: applications model them as text fields whose scripts format the value. The SDK recognizes the formats that Acrobat generates without executing the scripts, so fields driven by hand-written scripts are not recognized and read as plain text fields.
