AEM Este ejemplo de extensión de la consola de fragmentos de contenido es un barra de acciones que actualiza de forma masiva una propiedad de fragmento de contenido a un valor común.
El flujo funcional de la extensión de ejemplo es el siguiente:
Este ejemplo se extiende hasta el punto de extensión actionBar
para agregar un botón personalizado a la consola Fragmento de contenido.
AEM Interfaz de usuario extendida | Punto de extensión |
---|---|
Consola de fragmento de contenido | Barra de acciones |
El ejemplo utiliza un proyecto de consola de Adobe Developer existente y las siguientes opciones al inicializar la aplicación App Builder mediante aio app init
.

Bulk property update
An example action bar extension that bulk updates a single property one or more content fragments.
0.0.1
Add a custom button to Action Bar
Bulk property update
y
Add server-side handler
generic
La aplicación de extensión del App Builder generada se actualiza tal como se describe a continuación.
El src/aem-cf-console-admin-1/web-src/src/components/App.js
contiene el React router.
Existen dos conjuntos lógicos de rutas:
La primera ruta asigna solicitudes a index.html
, que invoca el componente React responsable de registro de extensión.
<Route index element={<ExtensionRegistration />} />
El segundo conjunto de rutas asigna direcciones URL a componentes de React que representan el contenido del modal de la extensión. El :selection
param representa una ruta de fragmento de contenido de lista delimitada.
Si la extensión tiene varios botones para invocar acciones discretas, registro de extensión asigna a una ruta definida aquí.
<Route
exact path="content-fragment/:selection/bulk-property-update"
element={<BulkPropertyUpdateModal />}
/>
ExtensionRegistration.js
, asignado al index.html
AEM route, es el punto de entrada para la extensión de la y define:
actionBar
o headerMenu
)getButton()
funciónonClick()
funciónsrc/aem-cf-console-admin-1/web-src/src/components/ExtensionRegistration.js
function ExtensionRegistration() {
const init = async () => {
const guestConnection = await register({
id: extensionId,
methods: {
// Configure your Action Bar button here
actionBar: {
getButton() {
return {
'id': 'bulk-property-update', // Unique ID for the button
'label': 'Bulk property update', // Button label
'icon': 'Edit' // Button icon; get name from: https://spectrum.adobe.com/page/icons/ (Remove spaces, keep uppercase)
}
},
// Click handler for the extension button
onClick(selections) {
// Collect the selected content fragment paths
const selectionIds = selections.map(selection => selection.id);
// Create a URL that maps to the
const modalURL = "/index.html#" + generatePath(
"/content-fragment/:selection/bulk-property-update",
{
// Set the :selection React route parameter to an encoded, delimited list of paths of the selected content fragments
selection: encodeURIComponent(selectionIds.join('|'))
}
);
// Open the route in the extension modal using the constructed URL
guestConnection.host.modal.showUrl({
title: "Bulk property update",
url: modalURL
})
}
},
}
})
}
init().catch(console.error)
Cada ruta de la extensión, tal como se define en App.js
, se asigna a un componente de React que se procesa en el modal de la extensión.
En esta aplicación de ejemplo, hay un componente React modal (BulkPropertyUpdateModal.js
) que tiene tres estados:
AEM Es importante señalar que cualquier interacción con los de la extensión debe delegarse a un Acción de Adobe I/O Runtime de AppBuilder, que es un proceso independiente sin servidor que se ejecuta en Adobe I/O Runtime.
El uso de acciones de Adobe I/O Runtime AEM para comunicarse con los usuarios es para evitar problemas de conectividad de Intercambio de Recursos de Origen Cruzado (CORS).
Cuando se envía el formulario de actualización masiva de propiedades, se crea un onSubmitHandler()
invoca la acción de Adobe I/O Runtime AEM AEM, pasando el host (dominio) actual de la y el token de acceso del usuario, que a su vez llama a la AEM API de fragmento de contenido para actualizar los fragmentos de contenido.
Cuando se recibe la respuesta de la acción Adobe I/O Runtime, el modal se actualiza para mostrar los resultados de la operación de actualización de propiedades por lotes.

AEM Una aplicación de App Builder de extensión puede definir o utilizar 0 o varias acciones de Adobe I/O Runtime.
