CI sessions and AJAX

[eluser]vickel[/eluser]
Hi Ochetski, thanks for your time

what I want to do is to check if a user has been inactive for x seconds. In case of inactivity I show a warning dialog box, which will log out the user in case he is not responding.

what I have is an ajax rich application and CI framework. After logging into the aplication part of the website I'm loading only one view. In this view I have a javascript which checks every x-seconds how the value of the session cookie is. And there I have my problems. Maybe I'm checking the wrong way?

I use:

Code:

document.getElementById('txt2').value='<?=$this->session->userdata('last_activity')?>';

which should write the cookie value into a div with the id 'txt2'
