Ik heb een stukje js waarmee ik een tab menu op de html maak en tevens de header en footer voor de geselecteerde pagina genereer. Het vervelende nu is dat als op de pagina zelf ook een XMLHttpRequest wordt gedaan de header en footer niet ingevuld worden mbv onderstaande code...
In bijvoorbeeld de pagina:

Code: 
//load the specified url -asynchronously- and pass the response to the specified callback function
function ajax_asynch(url, callback) {
	try {
		if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari
			req = new XMLHttpRequest();
		} else { // code for IE6, IE5
			req = new ActiveXObject("Microsoft.XMLHTTP");
		}
		req.onreadystatechange = function() {
			if (req.readyState == 4 && callback) {
				callback(req.responseText);
			}
		}
		req.open("GET", url, true);
		req.send(null);
	} catch (error) {
		alert('While accessing this URL:\r\n\r\n' + url + '\r\n\r\nthe following error occurred:\r\n\r\n' + error);
	}
}
function ajax(url, callback) {
	try {
		if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari
			req = new XMLHttpRequest();
		} else { // code for IE6, IE5
			req = new ActiveXObject("Microsoft.XMLHTTP");
		}
		req.onreadystatechange = function() {
			if (req.readyState == 4 && callback) {
				callback(req.responseText);
			}
		}
		req.open("GET", url, false);
		req.send(null);
	} catch (error) {
		alert('While accessing this URL:\r\n\r\n' + url + '\r\n\r\nthe following error occurred:\r\n\r\n' + error);
	}
}

// read the nominal values
function read() {
	var url = '/json.exe?_NOMINAL_F,_NOMINAL_U[0..3],_NOMINAL_I[0..3],_VTPRIM[0..3],_VTSEC[0..3],_CTPRIM[0..3],_CTSEC[0..3],time=' + new Date().getTime();
	ajax_asynch(url, function(response) {
		var data = eval('(' + response + ')');
	    var f = data['_NOMINAL_F'][0];
		var vl = data['_NOMINAL_U'][0];
		var il = data['_NOMINAL_I'][0];
		var vtp = data['_VTPRIM'][0];
		var vts = data['_VTSEC'][0];
		var ctp = data['_CTPRIM'][0];
		var cts = data['_CTSEC'][0];
		
		document.getElementById('freq').value = f;
		document.getElementById('v1').value = vl[0]; //same var for l1,l2,l3,n		
		
		document.getElementById('il1').value = il[0];
		document.getElementById('il2').value = il[1];
		document.getElementById('il3').value = il[2];
		document.getElementById('il4').value = il[3];
		
		
		document.getElementById('pv').value = vtp[0];
		document.getElementById('sv').value = vts[0];
		document.getElementById('pc').value = ctp[0];
		document.getElementById('sc').value = cts[0];
	});
}

// write the nominal values
function write() {
var url = '/json.exe?'+
		'_gbluser,'+
		'time=' + new Date().getTime();
	ajax(url, function(response) {					 
		var data = eval('(' + response + ')');
	    user = data['_GBLUSER'][0];

	});		

	var pwd = document.getElementById('pwd').value
	document.getElementById('pwd').value = '';
	if (pwd != user) {
		alert('Invalid password');
		return;
	}
	var url = 'dummy.html?';
	url += '_NOMINAL_F=' + document.getElementById('freq').value;

	document.getElementById('write').onclick = write;
	read();

Weet iemand hoe dit probleem op te lossen is?

Alvast bedankt.
