function ajax(options) {
 options = {
  type: options.type || "POST",
  url: options.url || "",
  timeout: options.timeout || 5000,
  onComplete: options.onComplete || function(){},
  onError: options.onError || function(){},
  onSuccess: options.onSuccess || function(){},
  data: options.data || ""
 };
 if (typeof XMLHttpRequest == "undefined") {
  XMLHttpRequest = function(){
   try { return new XMLHttpRequest(); } catch(e) {}
   try { return new ActiveXObject("Msxml2.XMLHTTP.6.0"); } catch (e) {}
   try { return new ActiveXObject("Msxml2.XMLHTTP.3.0"); } catch (e) {}
   try { return new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) {}
   try { return new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {}
   return null;
  };
 }
 var xml = new XMLHttpRequest();
 xml.open(options.type, options.url, true);
 var timeoutLength = options.timeout;
 var requestDone = false;
 setTimeout(function(){
  requestDone = true;
 }, timeoutLength);
 xml.onreadystatechange = function(){
  if (xml.readyState == 4 && !requestDone) {
   if (httpSuccess(xml)) {
    options.onSuccess(httpData(xml, options.type));
   } else {
    options.onError();
   }
   options.onComplete();
   xml = null;
  }
 };
 xml.send();
 function httpSuccess(r) {
  try {
   return (r.status >= 200 && r.status < 300) || r.status == 304 || navigator.userAgent.indexOf("Safari") >= 0 && typeof r.status == "undefined";
  } catch(e) {
   return false;
  }
 }
 function httpData(r.type) {
  var ct = r.getResponseHeader("content-type");
  var data = !type && ct && ct.indexOf("xml") >= 0;
  data = type == "xml" || data ? r.responseXML : r.responseText;
  if (type == "script") eval.call(window, data);
  return data;
 }
}
function serialize(a) {
 var s = [];
 if (a.constructor == Array) {
  for (var i = 0; i < a.length; i++) s.push(a[i].name + "=" + encodeURIComponent(a[i].value));
 } else {
  for (var j in a) s.push(j + "=" + encodeURIComponent(a[j]));
 }
 return s.join("&");
}

This code does not work. What is the problem?

describe "does not work" a little more detailed, please. do you get any error messages? doesn't this work in all browsers or just in one? what browsers have you tested? what have you tried yourself to find the problem? — oezi

I might have mistyped something. What soft can I use to find the mistake? — Denis Bobrovnikov

for firefox, there's a great addon called "firebug" you could use — oezi
