> The tags are just a feature of the template language. Their purpose is to
render the response that django will send to the browser. There is no
automatic coupling to actions in the browser. As you note, by the time
that the initial page load completes, the tags have finished all that they
are going to do.
I'm guessing that what you want calls for an AJAX scheme: You arrange for
click to produce an AJAX request (there is jquery support), which the
browser sends back to a specified (almost certainly different) url (but
probably on the same server/django). Your urlconf must route this to a
view that recognizes the AJAX request, and returns data (xml, json, ...)
needed to define the content that you want to show, and returns it as a
response. When this arrives back at the browser, a JavaScript function
that you have designated as the AJAX request's success callback is invoked
with access to the returned data. This function must modify the DOM
according to the data.
