How do I get the total number of pages in PDF?

I use previousButton and nextButton to control the number of pages.
but I can't get the total number of pages in PDF , it made the nextButton easy to make mistakes

I assume you figured this out already but the onDocumentComplete event passes in the total number of pages as an argument. You can see an example in the readme.

Thank you for your reply. I didn't read the document carefully enough.
