I needed a function that would take the input of a form, show a loading graphic for a few seconds, and then load some content from an ajax page with jQuery load().
The loading is easy, but i had to experiment a little to get the right syntax for the 'wait a few seconds' part.
Here's what i came up with... this is all part of a function that runs 'onclick' from a link.
var loadingGraphic = '<img src="loading.gif">';
var gameContent = 'ajaxpage.cfm';
