Extracting pages from a form and keeping them interactive (usable) is not doable because of cross page dependancies and reliance on root subform containers.
I assume you are doing this after the form is filled in. If the form is an XFA form then you coudl extract the data, manipulate the base form to pull out a blank page, then remerge the data back onto the form (single page). This would involve lots of code (not javascript in the PDF) - XML manipulation. If you are not code savvy then I woudl not even attempt it.
