DHTML Tooltips SE Safe?

Question about DHTML Tooltips and its Impacts.

[Daemon]

Are DHTML Tooltips SE Bots safe?

i.e.: A link with a onClick JavaScript Event that moves and write into a hidden layer that becomes visible.

Do you think it is a good idea? I'm thinking of using this method as quick glossaries to explain industry-related terms to customers on a webpage.

Thanks!

This is starting to becoming a good help technique. I don't really see a big issue. If you got a hand review then SEs could see you were using it for the user and not stuffing.

Since it's JavaScript, can SE read it? (yet?)

Thanks.

Google has been indexing js files for while now. I prusume you have a div with disply of 0?

I haven't implemented it yet but I assume I will have a hidden empty DIV which a JS function will move it to the clicked link location. The JS will populate the DIV with its description.

(I would show an example...do I have the right to put links on this forum? It's not a personal site, example from a big corporation)
