Reload AJAX data every X minutes/seconds, jQuery

Question

I programmed a CMS that has a log of who has recently logged into the system. Presently, this data is fed into a jQuery UI tab via Ajax. I would like to put this information

Answer 1

The simplest way (whether its the best way is subjective - for the use case you've presented I'd say its fine) would be to do:

var updateInterval = setInterval(function() {
  $('#whereIWantToDisplayIt').load('/thePathToThatScript.php');
},30*1000);

Every 30 seconds, this would load the output of your PHP script, and put that output into the element with ID = whereIWantToDisplayIt

I prefer Seb's answer though.
