Questiongetting error when typing in userid field. [modified] Pin

I am getting error while entry in userid field. When user enter his user id, an event is fired immediately and user id is verified using AJAX method. But I am getting error 'Object doesn't support this property or method'.

I am using ajax technique to verify userid from database just after entry in userid field and moving to next item.


<script type="text/javascript">
var xmlHttp

function userid1(str){
  xmlHttp=GetXmlHttpObject();
  if (xmlHttp==null) {
    alert ("Your browser does not support AJAX!");
    return;
  } 
  var url="checkuser.asp?q="+str+"&sid="+Math.random();
  xmlHttp.onreadystatechange=stateChanged;
  xmlHttp.open("GET",url,true);
  xmlHttp.send(null);
}

function stateChanged() { 
  if (xmlHttp.readyState==4) {
    document.getElementByClass("login1").innerHTML=xmlHttp.responseText;}
}

function GetXmlHttpObject(){
  var xmlHttp=null;
  try { xmlHttp=new XMLHttpRequest();  }   // Firefox, Opera 8.0+, Safari
  catch (e){ 
    try {xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");}   // Internet Explorer
    catch (e){xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");}
  }
  return xmlHttp;
}

</script>
