jQuery UI
includes autocomplete functionality through its .autocomplete() widget.
The autocomplete textbox can be as-you-type spell check enabled with RapidSpell
Web Java, and some small code changes/additions.
The code
works by activating autocomplete on the RapidSpell IFRAME element and manually
handling key events to trigger autocomplete.
