hi christina,
I don't see why you want to use woody/cforms
for that. you also didn't mention if the image is completely generated
serverside.
I'd
- use an <input type="image"> or
an image with an imagemap
- process the requests triggered
by corresponding clicks, getting the point clicked
- based on the processing generate the
new image and probably store it somewhere temporarily (e.g.
session)
- deliver the new image on the next
request to it
Maybe my question is silly because I am new to web
development.
I have a picture. I want
to position serveral handred points onto this picture,
whenever users click one of those points, the responding
piont's color is changed, some event like a "change" is
invoked so that woody form in this page can be
changed accordingly.
But now I totally have no idea how to achieve that
1. how to position so many points on a
picture and change the responding point upon click? of course each point has
an id
2. how to produce a "change" event when clicking on
any pionts?
3. and what components of
cocoon can help?
Thank you for your advice!!
Thanks a
lot!!!!
