Managing user actions with jQuery

I want to write javascript that will kill sestion on a web page if the user does not take any action for some time taken from the configuration. How can I find out that the user hasn’t done anything with jQuery.

Many thanks.

You can catch the mousedown and keydown events for the entire document, and then set the timeout to fire if the events are not raised within a certain period of time:

<html>
  <head>
    <script type="text/javascript" src="jquery-1.4.2.min.js"></script>

    <script type="text/javascript">
        var _idleEventId = null;
        var _idleMaxMilliSeconds = 10000;

        function OnIdle() {
            alert('You\'re idle!');
        }

        $(document).bind("mousedown keydown", function() {
            clearTimeout(_idleEventId);
            _idleEventId = setTimeout(OnIdle, _idleMaxMilliSeconds);
        });

        $(document).ready(function() {
            _idleEventId = setTimeout(OnIdle, _idleMaxMilliSeconds);
        });
    </script>
  </head>
  <body>
    Hello World
  </body>
</html>

how to use cookies just in case: http://www.w3schools.com/JS/js_cookies.asp

then i would like it

: !

setInterval("checkForActivity()", 5000); //set a reasonable time..

function checkForActivity() {
    var user_has_moved_at = (new Date()).getTime(); //generate a time
    var time_elapsed = getCookie( COOKIE_NAME ); //get a time from previous stored
    //check how many time is passed from last move
    if ( ( user_has_moved_at - time_elapsed ) < 3600 ) { 
     //less then 1 hour.. user is still here..
        $(document.body).bind('mousemove',
        function() {
         // so update the fresh air...
            setCookie( COOKIE_NAME , user_has_moved_at);
         // unbind event
            $(document.body).unbind('mousemove');
        });

    } else {
     // more then 1 hour... destroy cookie... user is out
        setCookie(COOKIE_NAME, null); //destroy cookie
    }

};

To verify that the user has not done anything, you can monitor events that mean user interaction:

var last_seen = 0;
var timeout = null;
$('body').mousemove(function () {
  last_seen = (new Date()).getTime();
  window.clearTimeout(timeout);
  timeout = window.setTimeout(clear_da_session, 10000);
});
/* ...  and likewise for things like
   $('input').focus();
   $('a').click();
   and 'keypress' events
*/

Elements clearTimeoutand setTimeouttake care of something (ie, functions clear_da_session) that occurred after some time without running any of the following events.

However, I want to emphasize once again my comment from above: do not do this at home, children! Use everything that has your server language on board. This is much more reliable than trying to track something that might not be understood.
