So we need a single php script that does the following.
(It most likely need some form a javascript library as well in order for it to work which is fine. If possible, it needs to use jquery as we already have the library embedded.)
We have a database of about 20,000 medical terms. We currently have to hand edit content on a page and link specific medical terms to the database so that through a mouseover effect, the definition of the medical term is displayed (from the database of the 20,000 terms).
We need a script to basically look at the content of a specific div on a page and identify any medical terms that appear in the database of terms. This has to happen AFTER the page loads.
If you are familiar with how Kontera advertising works, this would be exactly the same way - except that the terms that light up on the page are from the database of terms.
There might already be a plugin for jquery that does this - so if there is, all you have to do is customize it for us.
We of course use PHP and mysql.
