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
}
