Dear Paulo,
I try to add the js code into "text 4" to get the sum
value of the other 3 fileds.
I try to use the JS code by Adobe acrobat. But, it
didn't work:
String code = "AFSimple_Calculate(\"SUM\", new Array
(\"Text 1\", \"Text 2\", \"Text 3\"));";
Please give me advise.
Thanks
yun
Document document = new Document(PageSize.A4, 50, 50,
50, 50);
PdfWriter writer = PdfWriter.getInstance(document, new
FileOutputStream("text_fields.pdf"));
document.open(); int yp; TextField app;
PdfFormField field;
yp = 700;
app = new TextField(writer, new Rectangle(100, yp, 100
+ 100, yp + 20), "Text 1");
field = app.getTextField();
writer.addAnnotation(field);
yp = 650;
app = new TextField(writer, new Rectangle(100, yp, 100
+ 100, yp + 20), "Text 2");
field = app.getTextField();
writer.addAnnotation(field);
yp = 600;
app = new TextField(writer, new Rectangle(100, yp, 100
+ 100, yp + 20), "Text 3");
field = app.getTextField();
writer.addAnnotation(field);
yp = 550;
app = new TextField(writer, new Rectangle(100, yp, 100
+ 100, yp + 20), "Text 4");
field = app.getTextField();
String code = "AFSimple_Calculate(\"SUM\", new Array
(\"Text 1\", \"Text 2\", \"Text 3\"));";
PdfAction ac = PdfAction.javaScript(code, writer);
field.setAction(ac);
writer.addAnnotation(field);
document.close();
System.out.println("Finished.");
