To add to that.
AJAX uses javascript same as the above to insert it's calls.
I use AJAX for things like when the customer changes in the drop box I
use AJAX to query the database on the server and replace another drop
box on the browser (product codes specific for that client).
It looked to me that you wanted to track what the user was doing and
report centrally on the server. If that is the case then you must bring
that information back somehow AJAX is just one way of doing this.
What are you actually trying to achieve?
What do you know up front?
How much does information change?
