Abstract

We present a system to generate JavaScript programs for user input validation and automatic computation on HTML documents from completely declarative descriptions. Its input is an HTML document with validation conditions and constraints, and its output is an HTML document with a JavaScript program for validation and constraint satisfac tion. Our system makes it easy to develop and maintain client side programs for that purpose because there is no need to write any procedure. The generated programs not only provide interactive action and help to keep consistency among data in input forms on client side but also will re duce both network traffic and load on server side. This technique can be applied to other electronic doc uments such as PDF documents, VoiceXML documents and Wireless Markup Language documents because client side programs are available in them.
