Exportar fragmento de contenido a XML

Ejemplo de extensión de menú de encabezado del Editor de fragmentos de contenido

Se pueden agregar botones personalizados al menú del encabezado del Editor de fragmentos de contenido mediante el punto de extensión headerMenu. Este ejemplo muestra cómo añadir un botón al menú de encabezado y cómo gestionar el evento de clic para exportar el fragmento de contenido activo como XML o CSV.

Los botones de encabezado pueden existir como un solo botón o como un botón con subelementos. Este ejemplo muestra cómo implementar un botón con subelementos, pero incluye el código comentado para implementar un solo botón.

Punto de extensión

Este ejemplo se extiende al punto de extensión headerBar para agregar un botón personalizado al Editor de fragmentos de contenido.

Extensión de ejemplo

En el siguiente ejemplo se crea un botón de menú de encabezado con dos subelementos, uno para exportar el fragmento de contenido activo como XML (implementado) y otro para exportar el fragmento de contenido activo como CSV (no implementado).

El código muestra cómo se puede obtener el contenido del fragmento de contenido en el archivo de registro de la extensión y cómo se puede transformar el contenido JSON del fragmento de contenido y exportarse.

Registro de extensiones

AEM ExtensionRegistration.js, asignado a la ruta index.html, es el punto de entrada para la extensión de la y define:

  • AEM La ubicación del botón de extensión aparece (headerMenu) en la experiencia de creación de la
  • Definición del botón de extensión en la función getButton()
  • El controlador de clic para el botón, en la función onClick(), o una lista de subelementos y sus controladores de clic.

Datos de fragmento de contenido

El fragmento de contenido activo se puede recuperar mediante el método getContentFragment() en el objeto guestConnection.host.contentFragment.

const contentFragment = await guestConnection.host.contentFragment.getContentFragment();

El objeto contentFragment contiene toda la información acerca del fragmento de contenido, incluida la ruta de acceso, el modelo, los metadatos, el contenido principal y cualquier variante.
