Code not working in IE8

[anonymous]

Hello fellas - I need help, been on this for a whole day now. My code runs on all browsers except for IE8.. Can anybody help me?

function getmodel(str) { var xmlhttp; if (str=="")

{ document.getElementById("model").innerHTML=""; return; }

if (window.XMLHttpRequest)

{ code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); }

else

{ code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); }

xmlhttp.onreadystatechange=function()

{ if (xmlhttp.readyState==4 && xmlhttp.status==200)

{ document.getElementById("model").innerHTML=xmlhttp.responseText; }

}

xmlhttp.open("GET","getmodel.asp?model="+str,true); xmlhttp.send(); }

Regards

This is a great question for StackOverflow. There's not even any jQuery in it!
