<script language="javascript" type="text/javascript">
function showHint(str)
{
var xmlhttp;
document.write("string: ".str);
//document.write("string length: "+str.length);
if (str.length==0) //this is when user enters nothing, and presses Enter on keyboard
{ //alert("you didn't enter any name");
document.getElementById("txtHint").innerHTML=""
return;
}
if (window.XMLHttpRequest)
xmlhttp=new XMLHttpRequest();
else
xmlhttp=new activeXObject("Microsoft.XMLHTTP");
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
