Understanding Flash Forms

HTML forms are pretty easy to create and work with, but they are also very limited and not overly capable. For example:

  • Making fields required, or enforcing data validation, requires the user of client-side scripting (which may not be supported or enabled) or server-side processing (which is not very user-friendly).

  • There is no easy way to extend data types, for example, to display a pop-up calendar to allow simple date selection (and to ensure that dates are entered correctly).

  • Form presentation tends to be very tied to form contents. Changing form layout (adding or reordering fields, for example) often requires lots of tinkering with presentation code.

  • It is very difficult to reuse form layout and presentation, and even more difficult to simply make changes to the presentation of all forms (maybe to change color schemes or label alignment).
