Hi Krishnakant,
I'm not sure if this is exactly what you're asking, but what I've done
before is use scripting in the template to build up a Javascript array. For
instance:
-------------------------------------------------------------------
var authors = new Array();
% for post in c.posts:
authors[${post.id}] = "${post.author}";
% endfor
-------------------------------------------------------------------
Then you can loop through or access the array client-side whenever it's
needed. This isn't fundamentally any different than what Rick already said,
so it will really just depend on how you want to be able to access the data
later. If you're trying to access the data dynamically from the server then
you'll want to look into an AJAX solution.
Best,
Eric
