Unobtrusive Javascrips with jQuery - Loading Spinner

How to effortlessly and unobtrusively have a loading spinner appear on each ajax call with jQuery.
Ajax loading spinner


There are a number of reasons why, and they fall in a number of different categories

  • Development - unobtrusive code degrades well by definition, and the effortless part explains itself.

	var loading = $('<img alt="loading" src="/images/loading.gif" />')
	// Make the image appear during ajax calls
