如何在iframe中的ajax请求后滚动到顶部？

Question

I have the following jQuery code in an iframe:

<script>
jQuery("#logBtn").click(function(){
    jQuery("#content-promo").load("/path/to/file.php", function(response, status, xhr) {
      if (status == "error") {
      var msg = "Sorry but there was an error: ";
      $("#error").html(msg + xhr.status + " " + xhr.statusText);
      }else{ //update
        $("html, body").animate({ scrollTop: 0 }, "slow");
      }
    });

    return false;
});
</script>

How can the iframe scroll back to the top after the AJAX-request?

Use:

$('#my-frame').scrollTop();
