[jquery] jQuery show for 5 seconds then hide

I'm using .show to display a hidden message after a successful form submit.

How to display the message for 5 seconds then hide?

You can use the below effect to animate, you can change the values as per your requirements

$("#myElem").fadeIn('slow').animate({opacity: 1.0}, 1500).effect("pulsate", { times: 2 }, 800).fadeOut('slow'); 

Just as simple as this:

$("#myElem").show("slow").delay(5000).hide("slow");
