[thelist] Javascript: Preview a textarea in another window

[Lars G. Skjellerup]

My 10 cent's:

Why not take a look at another way of doing it:

http://24ways.org/advent/edit-in-place-with-ajax

It uses prototype.js to make a Ajax call to the server (eventually to
process the input someway) without posting the whole page back to the
server.
I should be possible to adapt it to call a server script thru the ajax and
do a popup showing the preview.

On a side note: Dreadfull thing popups - should be avoided in imho.
