iText doesn't process the PDF Javascript and I don't think that you will
find anything to do it except from Adobe. If you know what the formating
will be you can set the field with the value and what will be actually
displayed, for example:
form.setField(key, "1234.5", "1,234.50");

> Basically I am trying to stamp a field on a pre-existing PDF

> this.getField("sign").value = "-"
> } else {
> this.getField("sign").value = " "
> }
> event.value = util.printf("%,0.2f", Math.abs(event.value));

> The purpose of this JavaScript is to format a given number as

> of the number,
> for example, "1234.5" would be displayed as "1,234.50" in the
> main field and
> " " in the sign field and "-1234.5" should be displayed as
> "1,234.50" in the
> main field and "-" in the sign field (it's for a financial based
