Dobry den v hlavicce stranky mam:

	<script type="text/javascript">

		/* AJAX Script */

		function send_xmlhttprequest(obsluha, method, url, content, headers) { 

			var xmlhttp = (window.XMLHttpRequest ? new XMLHttpRequest : (window.ActiveXObject ? new ActiveXObject("Microsoft.XMLHTTP") : false));

			

			if (!xmlhttp) {

				return false;

			}

			

			xmlhttp.open(method, url);

			xmlhttp.onreadystatechange = function() {

			obsluha(xmlhttp); };

				if (headers) {

					for (var key in headers) {

						xmlhttp.setRequestHeader(key, headers[key]);

					}

				}

			xmlhttp.send(content); return true;

		}

		

				

		

</script> 	

V tele stranky mam

<script LANGUAGE="JavaScript">







	function sendToTerminal(prefix, comValu){

		if(!send_xmlhttprequest(terminal, 'GET', 'terminal.php/?sender[' + prefix + ']=' + comValu)){

			alert("Timeout");

			return false;

		}

		return true;

	}















	function terminal(xmlhttp) {

		if (xmlhttp.readyState == 4) {

			var odpovedi = xmlhttp.responseXML.getElementsByTagName('odpoved');

			for (var i=0; i < odpovedi.length; i++) {

				document.getElementById(odpovedi[i].getAttribute('id')).firstChild .data = odpovedi[i].firstChild.data;

			}

		}

	}



</script>

sendToTerminal(document.getElementById("prefix").innerHTML, document.getElementById("command").value);

Chyba: xmlhttp.responseXML has no properties
