How to make a stub in this script?

Question

JavaScript

There is this script:

var auto_refresh = setInterval(
function ()
{
$('#view_chats').load('chat-records.php').fadeIn(3000);
}, 1000);

The problem is that when the page is loaded for the first time, the posts start to appear after a second, i.e. with a delay. How to make a stub (Loading for example) on the first page load until the entries appear?
