jQuery showLoading.js: Loading Indicator Demos

Usage with jQuery load method:
jQuery('#activity_pane').showLoading();
jQuery('#activity_pane').load(
    '/path/to/my/url', 
    {},
    function() {
      //
      //this is the ajax callback 
      //
      jQuery('#activity_pane').hideLoading();
    }
);
