Clear Div before Ajax loads

I am using the ajax script below to populate the div "txtHint"...The script returns everything that is echoed in the update_chauffer.php page. I need to clear the div "txtHint" before ajax loads and displays the information again. Basically I am inserting information into mysql then running a query to display information based on the query so I am continually adding to the query results...Thanks
<script type="text/javascript">
function UpdateChauffer(str)
{
if (str=="")
  {
  document.getElementById("txtHint").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("txtHint").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","update_chauffer.php?ride=<? echo $_GET['id']; ?>&q="+str,true);
xmlhttp.send();
}
</script>

Currently you do the job only if str is empty :

function UpdateChauffer(str)
{
if (str=="")
  {
  document.getElementById("txtHint").innerHTML="";

we may do it all time :

function UpdateChauffer(str)
{
  document.getElementById("txtHint").innerHTML="";
if (str=="")
  {

If you don't see the content cleared this is because you're don't clear the right div, perhaps you more than one or need to clear a parent div
