[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

tal:content=string:var img_url='${img_url}';/script
Your popup javascript can then refer to the 'img_url' JS variable to set
the window location.
A little bit cleaner approach would be to have an ordinary link:
a class=magnify href=path/to/big/imageimg src=path/to/thumbnail
width, height ... //a
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.

Tino

Subject: Re: [Zope] open image in a fitted new window
The answer to your question is Yes if there's no other way of clicking
on a link and open an image in a fitted new window of my browser that
zope can cope without using javascript.
But putting in other words what I really would like to know: does zope
have its own way of clicking on a link and open an image in a fitted
new window without buttons, address field etc.?
Zope only performs server-side actions. What you are describing are actions
that occur on the client-side (ie. on the user's pc/browser), therefore you
must use client-side tools (ie. javascript).
The only trick here is to get the javascript to include the dynamic
URL; everything else is not specific to Zope or ZPT. Here is the hack
I usually use for that::
!-- assumes that 'image' is bound to an actual Zope image object --
script type=text/javascript lang=JavaScript
tal:define=img_url image/absolute_url
tal:content=string:var img_url='${img_url}';/script
Your popup javascript can then refer to the 'img_url' JS variable to set
the window location.
Tres.
