I am looking for a way to do mouseovers to give the definition of particular words that are in a web page. I was trying to find something that would let me mark the begging and end of a section to be included. Something like...
http://www.dynamicdrive.com/dynamici...mltooltip2.htm
but I would like to use a text file or database to hold the words that match and there definition.

Any help would be appreciated.

Thanks,

I wrote a little thing to do this a long time ago.

It will require you to use definition tags though.

Basically, just wrap words to get it with <dfn> tags. ex

<dfn>MyHardWord</dfn>

Then include a definition list (with matching words) in the page somewhere (it can be hidden):

<dl>
   <dt>MyHardWord</dt>
  <dd>The definition of my word is...</dd>
</dl>

The code is pretty old, so try not to laugh too much. Maybe I'll get around to re-writing it sometime.
