I am new to JavaScript and I found a time out routine on the Web that does what I want but one thing.  The code pops up a message stating the time is about to expire and gives the user option of continue or cancel.  I want to change the code that if no response from the user that the application redirects to another page automatically.

 

<script type="text/javascript">

var sess_pollInterval = 60000;

var sess_expirationMinutes = 20;

var sess_warningMinutes = 2;

var sess_intervalID;

var sess_lastActivity;

function initSession() {

sess_lastActivity = new Date();

sessSetInterval();

$(document).bind('keypress.session', function (ed, e) {

sessKeyPressed(ed, e);

});

}

function sessSetInterval() {

sess_intervalID = setInterval('sessInterval()', sess_pollInterval);

}

function sessClearInterval() {

clearInterval(sess_intervalID);

}

function sessKeyPressed(ed, e) {

sess_lastActivity = new Date();

}

function sessLogOut() {

window.location.href = 'SignonScreen.aspx';

}

function sessInterval()

{

var now = new Date();

//get milliseconds of differneces

var diff = now - sess_lastActivity;

//get minutes between differences

var diffMins = (diff / 1000 / 60);

if (diffMins >= sess_warningMinutes) {

//warn before expiring

//stop the timer

sessClearInterval();

//prompt for attention

var active = confirm('Your session will expire in ' +

(sess_expirationMinutes - sess_warningMinutes) +

' minutes (as of ' + now.toTimeString() + '), press OK to remain logged in ' + 'or press Cancel to log off. \nIf you are logged off any changes will be lost.');

if (active == true) {

now = new Date();

diff = now - sess_lastActivity;

diffMins = (diff / 1000 / 60);

if (diffMins > sess_expirationMinutes)

{ sessLogOut(); }

else {

initSession();

sessSetInterval();

sess_lastActivity = new Date();

}

}

else

{ sessLogOut(); }

}

else { alert('here') };

}

</script>
