MooTools - Transición elástica

Muestra una transición de curva elástica con eventos de entrada, salida y salida. Tomemos un ejemplo en el que agregamos unmouse downevento a un elemento div junto con eventos de curva elástica. Eche un vistazo al siguiente código.

Ejemplo

<!DOCTYPE html>
<html>

   <head>
      <style>
         #elastic_in {
            width: 100px;
            height: 20px;
            background-color: #F4D03F;
            border: 2px solid #808B96;
         }
         #elastic_out {
            width: 100px;
            height: 20px;
            background-color: #F4D03F;
            border: 2px solid #808B96;
         }
         #elastic_in-out {
            width: 100px;
            height: 20px;
            background-color: #F4D03F;
            border: 2px solid #808B96;
         }
      </style>

      <script type = "text/javascript">
         window.addEvent('domready', function() {
            $('elastic_in').addEvent('mousedown', function(event) {
               this.set('tween', {duration: 'long', transition: 'elastic:in'});
               this.tween('width', [80, 400]);
            });
            
            $('elastic_out').addEvent('mousedown', function(event) {
               this.set('tween', {duration: 'long', transition: 'elastic:out'});
               this.tween('width', [80, 400]);
            });
            
            $('elastic_in-out').addEvent('mousedown', function(event) {
               this.set('tween', {duration: 'long', transition: 'elastic:in-out'});
               this.tween('width', [80, 400]);
            });
         });
      </script>
   </head>
   
   <body>
      <div id = "elastic_in"> Elastic : in</div><br/>
      <div id = "elastic_out"> Elastic : out</div><br/>
      <div id = "elastic_in-out"> Elastic : in-out</div><br/>
   </body>
   
</html>
