8. Dynamic Forms > 8.0. Introduction

Introduction

Giving scripted intelligence to web forms was the impetus that led to the development of the JavaScript language and the notion of a document object model. While a lot has happened to scripting in the meantime, forms still make frequent use of scripts to assist with user-friendly instantaneous interaction that otherwise requires a two-way trip to the server (and delays for the user) to accomplish.

Because of the comparatively long history of scriptable forms and form controls, it is comforting to know that most such scripts work with a wide range of browsers, and not just those that implement the W3C DOM. Even so, there are some misunderstandings about the combination of scripts and forms that I’ll attempt to clear up in this chapter.
