smart keyboard in jQuery

SO I have need to develop online keyboard using jQuery or anything else that can help me achieve following.

1. When I type any letter , it can check against bunch of words and keep only those Keys enable which are possible.

For example. In my word collection I have word "Hello". When I type "H" on the keyboard...it should only keep "e" "l" "o" keys enabled and everything else should be disabled.

Is there a Name for such keyboards ? Any Examples would be appreciated. Currently I am p开发者_开发知识库laning to do this using jQuery and AJAX. I can keep my word collection on server and then do a look up on every kep press.

This isn't an answer - I don't think an exact one would be possible here.

Perhaps you could use the custom meta set keyboard from Trufa's suggestion and combine that with one of the jQuery autocomplete plugins to update your word list and change the keys that are available.

If you wanted to use the full keyboard I'm sure there would be a way using jQuery selectors to activate and deactivate certain keys.
