在Adobe PDF中执行Javascript

Question

I'm using iTextSharp in C# to read the pdf and fill values for text fields in it and based on one text field value, I'm trying to run javascript action to fill two other fields before saving the document.

I can see the script store in the pdf but it is not executing. Is there a better way to run the scripts in iTextSharp or in adobe?

As far as I know, iText does not have an Acrobat JavaScript engine.

In order to run (Acrobat) JavaScript in your form, you will have to open it in Acrobat/Reader, and provide a trigger to execute the scripts. Depending on which event the scripts are attached, you would either just have to run them (for example in the pageOpen event of the page on which the document opens), or using this.calculateNow() (again) in the pageOpen event of the page on which the document opens. If you have a multi-page document, you may also add a mechanism which runs those scripts only once (how to do that has been explained many times in many places (here on stackoverflow, but also in the Adobe forums, the AcrobatUsers forums (rest in peace), PlanetPDF etc.).
