Echo
Description: Type any text in the input field provided, and see it echoed right above. Just for fun, type any decimal number and see it converted to a Roman number, and vice versa.
Features: Lowest possible level of interaction with web browser:
  • Simple monadic framework
  • Wrapping Javascript functions to become Haskell functions
  • Calling Haskell functions from Javascript
  • Access to Javascript (including DOM) objects and properties
  • Handling of Javascript exceptions in Haskell
  • Events handling
  • Third party code of some "general" purpose works in web browser
Tested with: Netscape 7/Linux, MSIE 6.0/Windows 2000
