FF works but not in IE

[Greaser9780]

Here is the .js file:

var xmlHttp

 

function showUser(str)

{

xmlHttp=GetXmlHttpObject()

if (xmlHttp==null)

{

alert ("Browser does not support HTTP Request")

return

}

var url="http://www.blah.com/blah/showUser.php"

url=url+"?q="+str

url=url+"&sid="+Math.random()

xmlHttp.onreadystatechange=stateChanged

xmlHttp.open("GET",url,true)

xmlHttp.send(null)

}

 

function stateChanged()

{

if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")

{

document.getElementById("txtHint").innerHTML=xmlHttp.responseText

}

}

 

function GetXmlHttpObject()

{

var 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;

}
