Hi Jason,

I see a few people have had a stab at this, but I have a feeling I know 
what you really meant ;-)

I'm wondering how I can do this little trick (sp_info is a globaly devide

option tal:repeat=group groups/existing/high
tal:content=group
tal:attributes=onmouseover string:doTooltip(event,
'${sp_info/${group}/common_name}')
   onmouseout=hideTip()
/option

So based on my the value of 'group' from my repeat, I want to use the value
to look up another value in a different dictionary.  It works if I do this:
(event, '${sp_info/whatever/common_name}') but does not like me using the
embedded ${group}.


try this:

tal:i repeat=group groups/existing/high
  option tal:define=event sp_info/?group/common_name
  tal:content=group
  tal:attributes=onmouseover string:doTooltip(event,'$event')
  onmouseout=hideTip()
  /option
/tal:i

cheers,

Chris

Re: [Zope] How to do this trick..

2006-03-27 Thread Ross Patterson 
tal:repeat repeat=group groups/existing/high
option tal:define=js_arg python:sp_info[group];
tal:content=group
tal:attributes=onmouseover string:doTooltip(event, 
'${js_arg}/common_name}') 
onmouseout=hideTip()
/option
/tal:repeat

The tal:repeat tags are to make sure the order of TAL operations
works properly with the tal:define being done *after* the tal:repeat.
Hope this helps.

Ross

The ${var} syntax is only for inserting a value in a string expression. 
Path expressions only take known names. If you want to look up a value 
based on a variable, you must use Python. Look at the first half of this:
