Forms - More About JavaScript Types

Kas Thomas

Forms - The Importance of Initial Conditions

Kas Thomas

It's usually a good idea to initialize variables with sane values as soon as they are created (and sanity-check incoming argument values before using them). Intialize your form fields to rational values. Don't just leave them blank or zero. If you do, you don't know what kind of nonsense might happen.

Add fill-in fields to static PDF forms

PDF forms are turning up at an increasing number of Web sites, but many represent the most basic conversion. Rather than allowing their forms to be filled in on line, many sites post static versions that must be downloaded, printed and filled in by hand. If you own the full version of Adobe Acrobat, you may be able to add fill-in fields to some forms so they can at least be completed electronically.
