How to get selector from jquery object?

Question

codes:

   var jqueryObj=$("#readme");
   alert(jqueryObj.length); // result == 0

Is it possible to get "#readme" from jqueryObj? as:

   alert(jqueryObj.selector); //i want get "#readme"

BTW: I want to get a selector, not an element identifier, and jqueryObj.length == 0.
