Hello,

I have an Ajax script I am using that works perfect in firefox, but the request isn't working in IE. I thought I had it set up to handle the browser differences...

What am I doing wrong?

Code:
<script type="text/javascript">
function showPreview(spnsr, pgm, cmp) {
	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==4) {
			document.getElementById("announcementPreview").innerHTML=xmlHttp.responseText;
		}
		if(xmlHttp.readyState==1 || xmlHttp.readyState==2 || xmlHttp.readyState==3) {
			var loadingImg = '<img src="images/loadingAnimation.gif" alt="Loading.." style="margin:auto;">';
			document.getElementById("announcementPreview").innerHTML=loadingImg;
		}
	}

	var appendString = "?spnsr="+spnsr+"&pgm="+pgm+"&cmp="+cmp;
	xmlHttp.open("GET","showAnnouncement.php" + appendString,true);
	xmlHttp.send();

}
  
</script>
