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 for clicking on
any pionts?
3. and
what components of cocoon can help?
Thank you for your advice!!
Thanks a lot!!!!
