thank you so much for your useful tutorial , but when I use the JS code blow i get a javascript error : [b]unepected indetifier[/b]


[code]
function handleMessages (url, resultID) {
  var obj;
  xmlhttp.open("GET", url, true);
  xmlhttp. {
       if (xmlhttp.readyState==4) {
            obj = document.getElementById(resultID);
            obj.innerHTML = xmlhttp.responseText;
       }
  }
xmlhttp.send();
return 0;
}

[/code]


what's the problem ?

[Barand]

Is it because part of the code is missing?

[code]function handleMessages (url, resultID) {
  var obj;
  xmlhttp.open("GET", url, true);
  xmlhttp.onreadystatechange=function() {        // <--  misssing code
       if (xmlhttp.readyState==4) {
            obj = document.getElementById(resultID);
            obj.innerHTML = xmlhttp.responseText;
       }
  }
xmlhttp.send();
return 0;
}[/code]
