Can all the JavaScript in a PDF be triggered by a single button?

We have developed an SBA loan tracking application that populates PDFs with data from the DB. The date formats in the DB are raw for SQL Server and Oracle. When the date fields on the PDF are filled in, they need to be in a "localized" string. I added the following which works great.
console.println(util.printd(2, new Date() ));
But there are dozens of date fields. I need them to format without actually visiting each individual field. Is there a way to automatically format the date fields in the PDF?
Or I can add a button to the form, so the users would only have to click once, but is there a way to activate ALL of the JS cformat script at once?
