How to change the order in natbib´s short citation?

Question

I´m using natbib with the apalike style. When using the short citation

\citet[p. 22]{Testauthor98}

it shows me

Testauthor (1998, p. 22)

What do i have to do/change in order to get the following result?

Testauthor (1998), p. 22

Answer 1

You could write (using ~ for a non-breaking space)

\citet{Testauthor98}, p.~22

(Obviously, this solution is not suited for reformatting large existing documents without changing the document body.)
