Books on javascript for acrobat

[Marietaa]

I got a book from John Deubert "Extending Acrobat Forms with JavaScript". Is there books like that but newer date? 

[Jean-Claude Tremblay]

Maybe this one [Enhancing Adobe Acrobat DC Forms with JavaScript] by Jennifer Harder published in Sept. 2017.

That book is riddled with nonsense. If you are a beginner, then do not trust anything in it.  

If you want to learn something about scripting PDF forms in Acrobat, then read the Acrobat documents on it and read the articles on this site:

https://www.pdfscripting.com

[Jean-Claude Tremblay]

Agree... on both statement.

https://www.pdfscripting.com/ is an amazing and accurate ressource.

Thank you, and John Deubert's book is quite good as well.  While the Acrobat UI has changed since the book was written, all the scripting is still the same.
