Thanks!

i put the code in this function:

			$(function() {
				refreshContent(); // Call refreshContent immediately
				setInterval('refreshContent()',10000);
			});
			
			function refreshContent()
			{
				$('.bar').width("100%");
			        $(".bar").animate({width: "0",}, 10000 );	
				$.post('testemonial-content.php',{}, function(resp) {
					$('div.cycle.contentleft:hidden').html(resp.left);
					$('div.cycle.contentright:hidden').html(resp.right);
					$('div.cycle').fadeToggle(0);
				},'json');
				
			}

Open in new window


and it sort of works as expected, for the first 2 rounds. after the content has switched twice, the bar doesn't run anymore.

Why does it stop running?

In modern browsers you do it with the CSS:

.bar {
             width:100%;
         }
.barActive {
                     width:0px;
                      transition:width 10s ease-out;
                  }
Then all you need is an event to change the className from 'bar' to 'barActive'.

I like that ease of use without js.  I have not fully embraced it yet because I enjoy making things overly complex for myself and get satisfaction from making it work.

Just add, "-webkit-transition:width 10s ease-out;" so it works with safari.  

If you are looking to do some type of timer that starts when an action happens like answering a test question, you will need to use javascript/jquery.

The 10 second interval occurs just a bit earlier than the animation is complete.
In order to have it working you have to stop the animation using the stop method.
$('.bar').stop().width("100%");
