You can use Java Script in your PDF files to do everything from changing their output, to changing the way PDF files look, to automatically creating a new PDF file and modifying its contents. It lets you automate the way forms are handled, allows your forms to make use of Web Templates functions and data in your database, and enable new user-interface capabilities.

You can get pretty fancy, even using the built-in Java Script tools in a PDF editor, such as Foxit Phantom PDF, to handle number strings, email a completed form, and insert the current date or hide certain text fields until a form is printed.

If you are in a situation where you want to run a piece of code repeatedly like updating something in the database based on user interaction or fetching records from database every 10 seconds or you want to load new stories via ajax similar to how facebook does on its homepage or some other similar situation, one would normally go for set Interval function something like this: Above, do Stuff function will get called every 10 seconds.

That is the normal approach most developers seem to go with. The set Interval will call do Stuff function exactly at specified time of 10 seconds again and again irrespective of whether do Stuff function actually finished doing what it is supposed to do.

(You may want to browse the Java Script Forum there while you’re at it.) Want to dabble in Java Script yourself?
