The best way is the following:
in the view:
<a href="#" onclick="ajax('{{=URL('change_n')}}',[],':eval');return
false">click me to increment n</a>
than create a controller action
def change_n():
# check this was called by the ajax post
if request.env.request_method=='POST':
# do anything you need to do
session.n=session.n+1
# optional return instructions in JS
return "$('.flash').html('n was incremented').slideDown();"
In the view:
ajax('...url...',[],':eval');return false
the url is the url of the callback action. [] is a list of optional
input names whose values you want to pass along. :eval tells web2py
the response will be in JS. return false prevents the browser from
reloading the page on click.
