How to have AJAX trigger the browser's loading indicator

Question

I\'m making an ajax-enabled lab scheduling program, and some of the ajax operations aren\'t exactly quick.

In Gmail, when you go to your inbox, send a message, etc.

I found a related answer here: Browser continues 'loading' after ajax request finishes.

You can create an iframe and open and close its contentDocument which seems to start and stop the browser's native loading animation. See an example here: http://jsfiddle.net/KSXkS/1/.
