[jQuery] Passing a variable into the $('selector') function

[Stompfrog]

Hi all,

I have a problem that I can't crack.

I have a function similar to this..

 $.ajax({
   type: "POST",
   url: "some.php",
   data: "name=John&location=Boston",
   success: function(msg){
     alert( "Data Saved: " + msg );
   }
 });

The data that gets passed back to the function from some.php is a
string which is the id of the div that I want to manipulate in the
callback function e.g. "#myDiv".

My question is how can I get that div from the callback function using
the msg variable because $(msg); doesn't work and neither does $
("'"+msg+"'");

Thanks in advance,
