We can do this with prototype....

Ajax.Responders.register({
  onCreate: function() {
    if($('spinner') && Ajax.activeRequestCount>0)
      Effect.Appear('spinner',{duration:0.5,queue:'end'});
  },
  onComplete: function() {
    if($('spinner') && Ajax.activeRequestCount==0)
      Effect.Fade('spinner',{duration:0.5,queue:'end'});
  }
