From Yahoo AJAX Howto

Determine AJAX

var xmlhttp = null; if (window.XMLHttpRequest) {

 xmlhttp = new XMLHttpRequest();
 if ( typeof xmlhttp.overrideMimeType != 'undefined') {
   xmlhttp.overrideMimeType('text/xml');
 }

} else if (window.ActiveXObject) {

 xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

} else {

 alert('Perhaps your browser does not support xmlhttprequests?');

}

Send request

xmlhttp.open('GET', url, true); xmlhttp.send(null);

Define Callback

xmlhttp.onreadystatechange = function() {

 if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
   // do something with the results
 } else {
   // wait for the call to complete
 }
