[SandeepThakurala]

hi i am new to web development and i am using js/ajax code to load o/p of php file in <div> tag. Now i am using a login.php file and i want that if login credentials are correct then further page should be open in current window else login fail message should be displayed below the username and password text box. following is the code i am using -

function updateLink(id,pwd){
    var oRequest;
    try {
        oRequest=new XMLHttpRequest();
    } catch (e)   {
        try {
            oRequest=new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
            try {
                oRequest=new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {
                alert("Your browser does not support AJAX!");
                return false;
            }
        }
    }
    oRequest.onreadystatechange=function() {
        if(oRequest.readyState==4)
        {
            var div = window.parent.document.getElementById('result');
            div.innerHTML = oRequest.responseText;
        }
    }
    var url = "updateLinks.php";
    url = url+"?id="+id;
    url = url+"&pass="+pwd
    oRequest.open("GET",url,true);
    oRequest.send(null);
}

how can i modify the above code to do above written task?

I would use a plain form for that and let PHP decide what page to load. works even with JavaScript disabled.
