Checking if user is offline/online

[António Ramos]

What could be the best way to check if a user is disconnects?

I was thinking of  this

     <script type="text/javascript">

       $(document).ready(function()

{

    $(window).bind("beforeunload", function() { 

        call a controller function to set the user as offline

    });

});

     </script>

but this is not perfect because when the user moves to another URL inside the same app this event keeps getting triggered on url change.

Any better ideas?

You need a websocket server like web2py/gluon/contrib/websocket_messaging.py Examples are i the file itself.

You can do it with javascript, using:

Api navigador:

Looks like that is for tracking whether the browser itself is online vs. offline, not whether the user has simply navigated away from your app or closed the tab.

In that context, "offline" means that the browser no longer has an internet connection.
