FadeIn DIV after AJAX pull

i have this bit of nasty code :P that updates a div using AJAX, but i would love to see a fadein effect on it. The thing is, i have an image that loads and appears during the interval where the div is not showing any content yet. Analyse the bottom of it. What can i do to make it fadein?

function testing(str)
{
var xmlhttp;
if (str=="")
  {
  document.getElementById("myDiv").innerHTML="";
  return;
  }
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {

    document.getElementById("myDiv").innerHTML=xmlhttp.responseText;
    }
  }
$('#myDiv').html('<div style="text-align:center; padding-top:195px;"><img src="../images/loaderajax.gif" width="220" height="19" /></div>');
xmlhttp.open("GET","getuser.php?q="+str,true);
$('#myDiv').hide();
xmlhttp.send();
$('#myDiv').fadeIn();
}

Your code is all wacky and out of order with your ajax call. You're using JQuery, so take advantage of it! :)

$.ajax({
   url: 'getuser.php',
   data: str,
   beforeSend(jqXHR, settings) {
        $('#myDiv').html('<div style="text-align:center; padding-top:195px;"><img src="../images/loaderajax.gif" width="220" height="19" /></div>');
    },
    error:function(jqXHR, textStatus, errorThrown) {
        $('#myDiv').html(textStatus + ' -- ' + errorThrown);
    },
    success:function(data){
        $('#myDiv').hide().html(data).fadeIn();
    }
 });

If you are okay with wrapping the returned content, I would do something like this in the ajax response:

$("<div/>").html(xmlhttp.responseText).appendTo("#myDiv").hide().fadeIn();

This will allow your image to show and only fade in the new content.

Put the fadein() call in the code that handles the response.

Any reason why you're using jQuery for the selectors and effects and not for the AJAX?
