javascript alert() function

I think its not possible to close javascript alert. Rather you can use any custom popup dialog box and then you have full control to set timeout to close the box.

Actually issue related with alert() function...

First I am Created one div like as follows

<div id="divReAssignDialog">Your session will expire in another 1 minute(s)! Please respond before the session expires</div>

<script language="javascript" type="text/javascript" charset="utf-8">

            $("#divReAssignDialog").dialog({
                width: 400,
                height: 150,
                autoOpen: false,
                modal: true,
                resizable: false,
                autoResize: true,
                close: function () { }
            });

   

            var authorized = "<%=  HttpContext.Current.User.Identity.IsAuthenticated.ToString().ToLower() %>";
            if (getAbsolutePath().toLowerCase() == 'sessionexpired.aspx') {
                authorized = "false";
                //alert(authorized);
            }
            if (authorized == "true") {
                var sessionTimeoutWarning = "<%= Session.Timeout %>";
                sessionTimeoutWarning = sessionTimeoutWarning - 1;
                var sessionTimeout = "<%= Session.Timeout %>";
                var sTimeout = parseInt(sessionTimeoutWarning) * 60 * 1000;
                setTimeout('SessionWarning()', sTimeout);
                function SessionWarning() {
                    $("#divReAssignDialog").dialog("open");
                }

            }
        </script>

Now this div is closing automattically...
