hi guys, i have this simple function

1.     $('#provider').change(function() {
           
           $('#tarif').load("ajax/order.php?atask=gettarifs", {
               'selectprovider' : $('#providerselect').val(),
               'current' : $('#current').val()
           });
       });
   
   
   
   
   
   

which loads a list from a php function.....now i want to display in <td id="tarif"></td> the message "loading..." until the function gets all data from php....how should i change it?
