Все нормально работает под IE 7, но не работает под FF и Opera - вываливаюсь по таймауту. Смотрю ActiveXObject и XMLHttpRequest, но тут кажется все нормально. Может есть у кого идеи? | Код |
<script type="text/javascript">
function XHConn()
{
var xmlhttp, bComplete = false;
/*
try {xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");}
catch (e) {try { xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");}
catch (e) {try { xmlhttp = new XMLHttpRequest();}
catch (e) {xmlhttp = false;}}}
*/
if (window.XMLHttpRequest) {
try {
xmlhttp = new XMLHttpRequest();
if (xmlhttp.overrideMimeType) {
xmlhttp.overrideMimeType('text/html');
}
} catch (e){}
} else if (window.ActiveXObject) {
try {
xmlhttp = new ActiveXObject('Msxml2.XMLHTTP');
} catch (e){}
try {
xmlhttp = new ActiveXObject('Microsoft.XMLHTTP');
} catch (e){xmlhttp = false; }
}
if (!xmlhttp) return null;
this.abort = function()
{
xmlhttp.abort();
}
this.connect = function(sURL, sMethod, sVars, fnDone)
{
if (!xmlhttp) return false;
bComplete = false;
sMethod = sMethod.toUpperCase();
try {
if (sMethod == "GET")
{
alert(sURL+"?"+sVars);
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");
xmlhttp.setRequestHeader("Content-length", sVars.length);
xmlhttp.send(sVars);
}
xmlhttp.onreadystatechange = function(){
if (xmlhttp.readyState == 4 && !bComplete)
{
bComplete = true;
fnDone(xmlhttp);
}};
xmlhttp.send(sVars);
}
catch(z) { return false; }
return true;
};
return this;
