Ajax is not working in firefox and opera

What error do you get? Check the console for errors or Firebug if you have it.

My code is working in firefox as well as in opera. I have changed onreadyStateChange to onreadystatechange .Then it is working in Opera, but not in firefox. . After this , I changed xmlhttp.open('GET',url,false) to xmlhttp.open('GET',url,true) .Now it is working IE, Opera and Firefox.

alert("Your Browser does not support AJAX");

}

var url="search.php";
url=url+"?q="+str;
url=url+"&sid="+Math.random();
xmlhttp.onreadyStateChange=statechanged;
xmlhttp.open('get',url,false);
xmlhttp.send(null);


}

function statechanged()
{
alert("ok");
if (xmlhttp.readyState==4)
{

document.getElementById("txt").innerHTML=xmlhttp.r esponseText;

}

}

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


How to solve this problem.

Thanks in advance

Replace with

xmlhttp.open('get',url,true);
