Please review the documentation. The second argument to the ajax() function
is a list of "name" attributes of form input elements -- it cannot simply
be a list of raw data values you want to pass to the server (and you
certainly shouldn't expect the Python identifiers used in the template to
appear in request.vars -- the Javascript code never even sees those
identifiers). In this case, because you are not extracting values from form
input elements but simply want to pass existing data values, you should
instead add those values to the URL itself:
ajax('{{=URL('default', 'about_group', args=row.id)}}', [], '{{=row.id}}')
With the above, in the controller you can get the value of row.id via
request.args(0). Also, note the change of the "target" argument to the
row.id value -- this will ensure that each target element gets its own
unique ID (you cannot give the same CSS id to multiple elements on the
page).

Re: [web2py] Re: Why is this ajax function not working fine?
a taddle bit of recap, seems that you're loosing the bigger picture
ANYTHING (or, the 99%) of things in views contained in a {{=blabla}} are
properly escaped.
Back to the "problem":
- first of all, you shouldn't generate multiple times.
Every element with an id attribute should be the only instance in the page
- second: you'd really check into what leonel suggested, it cuts the
complexity
- third, for completeness sake and for that only: in cases like this I like
to take a step back and iterate over small changes, to see where everything
is falling apart...
a) let's start with check about
b) let's get "something" become "ajax('url', ['parameter'], 'target');"
- check about
c) let's get "url" become a proper url
- check about
d) let's get "parameter" become the row.id
- check about
voilà, no syntax errors.

Re: [web2py] Re: Why is this ajax function not working fine?
now it says:
unexpected character after line
continuation character (default/index.html, line 83)
earlier it was giving no response on clicking as i expected it to work as
per its onclick function.

{{extend 'layout.html'}}
{{for row in rows:}}
{{=row.name}}
check
'about'
{{pass}}
def index():
rows=db(db.groups.id>0).select()
return locals()

return row.about
It ain't working with div onclick too. What's the problem now?

It shouldn't be on href it should be on onclick.
