Ajax Help ..

I don't know why this function never return an readtstate == 4 for me..

<script type="text/javascript">

function trimite(url, parametri, divname){


if (window.XMLHttpRequest) { Ajax = new XMLHttpRequest(); }
else if (window.ActiveXObject) { if(!Ajax){Ajax = new ActiveXObject("Msxml2.XMLHTTP");}
if(!Ajax){Ajax = new ActiveXObject("Microsoft.XMLHTTP");}
}

function schimbari(){

if(Ajax.readyState == 4){alert('OK');}
if(Ajax.readyState == 3){alert('Progrese');}
alert('Status:'+Ajax.readyState);
}


Ajax.open('POST',url,true);
Ajax.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded')
Ajax.onreadystatechange = schimbari();




}




</script>

 

any javascript errors?

 

No , the problem is that i did

Ajax.onreadystatechange = schimbari();
... this is not valid

it should be

Ajax.onreadystatechange = schimbari

otherwise it will loop just once, and i will never get an status 4 back ,only status 0 and 1 when i call it
