Time for action – adding easing


The easeOutBounce easing type adds a particularly attractive effect when used with slideDown() animations.

Note

The easing plugin can be obtained from http://gsgd.co.uk/sandbox/jquery/easing/jquery.easing.1.3.js. A copy of this file is included with the companion download for this book.

  1. Change the call to the slideDown() method in slideUp.html so that it appears as follows:

    $(this).addClass("on").next().slideDown(400, "easeOutBounce");
  2. Save the changed file as slideEasing.html. Don't forget to add a new <script> reference to the easing plugin directly after the jQuery reference to avoid a script error.
