How to show processing animation / spinner during ajax request?

Question

I want a basic spinner or processing animation while my AJAX POST is processing. I\'m using JQuery and Python. I looked at the documentation but can\'t figure out exactly

The best method I have found, assuming you are populating a present but empty field is to have a .loading class defined with background-image: url('images/loading.gif') in your CSS. You can then add and remove the loading class as necessary with jQuery.
