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.?

I was wondering how to once clicking on a image (thumbnail) I would get the full-size image in a fitted new window, without buttons, address field etc. I can realise how to do it with javascript but I don't know, if it's the only way, how to integrate javascript in a zpt. A example/tutorial would be very welcome so. What you're asking for? How to insert javascript code into html page?

Thanks Jonathan, I can understand your point. So I will google for a way (example/tutorial) of how integrating javascript in a zpt. Cheers, Alan On 22/03/07, Jonathan <dev101@magma.ca> wrote:

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.

A little bit cleaner approach would be to have an ordinary link: <a class="magnify" href="path/to/big/image"><img 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. Regards Tino
