popup, ajax, and popup.close()

Total Edit:

simpler problem

see this:

function loadXMLDoc(url){

if (window.XMLHttpRequest){

xmlhttp=new XMLHttpRequest();
xmlhttp.onreadystatechange=state_Change;
xmlhttp.open(“GET”,url,true);
xmlhttp.setRequestHeader(‘If-Modified-Since’, ‘Wed, 15 Nov 1995 00:00:00 GMT’);
xmlhttp.send(null);
}
else if (window.ActiveXObject){

alert(‘before’);
xmlhttp=new ActiveXObject(“Microsoft.XMLHTTP”);
alert(‘after’);
if (xmlhttp){
xmlhttp.onreadystatechange=state_Change;
xmlhttp.open(“GET”,url,true);
xmlhttp.send(null);
} else {
alert(‘Erro ao iniciar XML request’);
}
} else {
alert(“Error initializing XMLHttpRequest”);
return;
}

}

when called in ie, alert(‘before’) appears, alert(‘after’) never comes out, any ideas or is my ie f****d up?

Also in #JavaScript _↴
