Ho anche trovato questa libreria:
Codice PHP:
<script language="JavaScript" type="text/JavaScript">
function XHConn()
{
var xmlhttp, bComplete = false;
try { xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); }
catch (e) { try { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); }
catch (e) { try { xmlhttp = new XMLHttpRequest(); }
catch (e) { xmlhttp = false; }}}
if (!xmlhttp) return null;
this.connect = function(sURL, sMethod, sVars, fnDone)
{
if (!xmlhttp) return false;
bComplete = false;
sMethod = sMethod.toUpperCase();
try {
if (sMethod == "GET")
{
xmlhttp.open(sMethod, sURL+"?"+sVars, true);
sVars = "";
}
else
{
xmlhttp.open(sMethod, sURL, true);
xmlhttp.setRequestHeader("Method", "POST "+sURL+" HTTP/1.1");
xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
}
// QUI VAR bComplete
xmlhttp.onreadystatechange = function(){
if (xmlhttp.readyState == 4 && !bComplete)
{
bComplete = true;
fnDone(xmlhttp);
}};
xmlhttp.send(sVars);
}
catch(z) { return false; }
return true;
};
return this;
}
var myConn = new XHConn();
if (!myConn) alert("XMLHTTP not available. Try a newer/better browser.");
var fnWhenDone = function (pXML) { alert(pXML.responseText); };
myConn.connect("test.txt", "GET","",fnWhenDone);
</script>
Si tratta dello stesso utilizzo ?
Anche questo utilizzo di bComplete mi spiazza un po.
