In its own small way, learning JavaScript will be just such a threshold eventin your professional life. If you’ve been working with Acrobat for any lengthof time, you’ve probably gotten pretty good at it and have become quitecomfortable at creating forms, adding music, creating slide shows, and allthe other features Acrobat offers. This book introduces the New World. A knowledge of JavaScript allows youto do things within Acrobat that far exceed what you’ve done so far: You caninterface with databases; add your own pop-up menus; create forms withsophisticated, interactive interfaces; and implement form fields that can lookup prices and other data. These are only a few of the things you can dowithin your Acrobat documents using JavaScript. The extent to which youcan manipulate your Acrobat files is vastly greater with JavaScript skills thanwithout.
