[jQuery] simple selector problem :beginner();


I like to select every span, thats in "this"
$(this "span")
sorry, simple and stupid...
full function:
function liCounting (){
            $("#staerke1 li,#staerke2 li").each(function(liCounter){
                liCounter++; //set liCounter to 1, not 0
                $(this "span").replaceWith("<span>"+ liCounter +". </span>");
            })
            };
thx tom
