En este artículo, demostraremos el efecto de ScrollTo mediante el uso de la biblioteca de JavaScript llamada script.aculo.us que tiene una transición suave de uno a otro. También podemos ajustar la duración del efecto.
Sintaxis:
Effect.ScrollTo('element_id', { duration:'0.2', offset:-20 });
Nota: Para usar esta biblioteca, se supone que debemos instalar la biblioteca y luego usarla en nuestros programas. Y para hacerlo puedes seguir este enlace http://script.aculo.us/downloads .
Enfoque: Para demostrar el uso de esta función, hemos escrito un pequeño fragmento de código. Hemos escrito una pequeña función de JavaScript llamada método ShowEffect() que utiliza el método Effect.ScrollTo() de esta biblioteca. Al hacer clic en Click me to Scroll! , verás el efecto claramente.
Ejemplo: para ver el efecto, primero descargue la biblioteca y luego abra este programa en el entorno local.
