[Zope] Re: open image in a fitted new window
Thanks Tres and Tino.
BTW Tino, what do you mean with
"...or uses layers the big view on top with little DOM action (preferred)..."
something like passing the mouse point over the picture and have the
full-size version of the image?
Cheers,
Alan

A little bit cleaner approach would be to have an ordinary link:
and have a general javascript which scans thru the DOM after load,
finds the a-objects with class-attribute magnify and installs
an handler for mouse click which overrides the usual link action
and either pops up a window or uses layers the big view on top
with little DOM action (preferred). You dont even net buzzy "Ajax"
for this. The URL for the big picture is just encoded in the HTML
already, so you can use the usual tal: attributes to define in
ZPT.
The result is clean xhtml code which works in any case and only
is improved in case of javascript beeing available.
Regards
Tino
