var xmlHttp;
try
{ // Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest(); }
catch (e)
{ // Internet Explorer
try
{ xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); }
catch (e)
{ try
{ xmlHttp=new ActiveXObject("Microsoft.XMLHTTP"); }
catch (e)
{ alert("Your browser does not support AJAX!");
return false; } } }
xmlHttp.onreadystatechange=function()
{
if(xmlHttp.readyState==1){
document.getElementById('display').innerHTML="Loading...!";
}
if(xmlHttp.readyState==4)
{
document.getElementById('display').innerHTML=xmlHttp.responseText;
}
}
//alert(page);
xmlHttp.open("GET","URL",true);
