Delphi
[copy to clipboard]
{ PDF object is supposed to be created }
a := PDF.CreateJavascriptAction('this.getField("edit2").value = this.getField("edit1").value * this.getField("edit1").value;');

PDF.AddEditBox(10, 10, 90, 24, 'edit1');
PDF.AnnotUnicodeText := '3';

PDF.AddEditBox(10, 30, 90, 44, 'edit2');
PDF.AnnotUnicodeText := '9';
PDF.OnControlOtherChanged := a;

{ Now the square of the edit1 will be calculated }
{ in the edit2 when edit1 is changed. }
PDF.SaveToFile('test.pdf', true);
C/C++

// PDF object is supposed to be created
long a = PDF->CreateJavascriptAction("this.getField('edit2').value = this.getField('edit1').value * this.getField('edit1').value;");

PDF->AddEditBox(10, 10, 90, 24, "edit1");
PDF->AnnotUnicodeText = L"3";

PDF->AddEditBox(10, 30, 90, 44, "edit2");
PDF->AnnotUnicodeText = L"9";
PDF->OnControlOtherChanged = a;

// Now the square of the edit1 will be calculated
// in the edit2 when edit1 is changed.
PDF->SaveToFile("test.pdf", true);
