Re: Ajax (jquery) Question - am I doing this right?

Hi Brian,

thanks for your answer.

That's a neat trick to avoid the switch statement!

I've done the redirecting, because i thought it's more DRY. With your
solution (which works perfect!) i need to copy the admin_index method
in the admin_switchStatus method.
(In this particular case, it's only a pagination statement...so no
problem)...

But what if the logic comes complexer? Should I then move it to the
model?
