[jQuery] post data response problem

[jQuery] post data response problem


I am getting a data response from post in the form of
variable1 | variable2
I am having trouble splitting this and applying the results to where
its needed.
$.post($(this).attr("href")),{},
    function(data)
            {
         update = data.split('|');
        $(update[0]).replaceWith(update[1]);
            };
return false;
Thanks
