Need to update page numbers in footer after spawning hidden pages..

Hello, and need help...

 

I have a footer showing the page numbers (#/#) in an application I am creating. Easy peesy, but then I involve spawned hidden pages that can be respawned for more. But those pages with the footers don't update. The total number retains the original page count, and the sequence of pages do not adjust. 

 

Is there some way, perhaps a Javascript action, where I can get the pages on the footer to update?

That's a lot better, but there is a misunderstanding from the original answer. i thought JR meant to put this into the edit footer feature where I put the page numbers, where there is no opportunity to place any fields. Your solution seems to infer that to place a field on each page and then do a calculation script, which is a good idea. But unfortunately, I am running out of time and can't focus on learning through a ton of things I know, and don't need to know (right now), for this to get to the solution, so I give up. Thanks anyway..


The "edit footer" feature adds static content to the PDF pages. The footer text cannot be updated dynamically with a script. The only way to add dynamic page numbers to spawned Page Template is with a text field on the templates. 

 

Just add a calculation script to it using the code provided by JR.

Place this as a calculation script in the page number fields:

 

event.target.value = this.pageNum+1;

or

event.target.value = this.pageNum+1 + " / " + this.numPages;

 

==> You must add "calculateNow()" at the end of the spawning script to update these fields.

    Thanks, though I can't quite figure how to put script in the page number fields. I tried..  I am using Adobe Acrobat Pro, latest version. Help?
