Esporta frammento di contenuto in XML

Esempio di estensione del menu dell’intestazione dell’Editor frammento di contenuto

È possibile aggiungere pulsanti personalizzati al menu dell’intestazione dell’Editor frammento di contenuto utilizzando headerMenu punto di estensione. Questo esempio mostra come aggiungere un pulsante al menu di intestazione e come gestire l’evento clic per esportare il frammento di contenuto attivo come XML o CSV.

I pulsanti di intestazione possono esistere come un singolo pulsante o come un pulsante con elementi secondari. Questo esempio mostra come implementare un pulsante con elementi secondari, ma include il codice di commento per implementare un singolo pulsante.

Punto di estensione

Questo esempio si estende al punto di estensione headerBar per aggiungere un pulsante personalizzato all’Editor frammento di contenuto.

Estensione di esempio

Nell’esempio seguente viene creato un pulsante del menu di intestazione con due elementi secondari, uno per esportare il frammento di contenuto attivo come XML (implementato) e uno per esportare il frammento di contenuto attivo come CSV (non implementato).

Il codice mostra come è possibile ottenere il contenuto del frammento di contenuto nel file di registrazione dell’estensione e come è possibile esportare il contenuto JSON del frammento di contenuto.

Registrazione dell’estensione

ExtensionRegistration.js, mappato alla route index.html, è il punto di ingresso per l'estensione AEM e definisce:

  • Viene visualizzata la posizione del pulsante di estensione (headerMenu) nell’esperienza di authoring dell’AEM
  • Definizione del pulsante di estensione nella funzione getButton()
  • Il gestore di clic per il pulsante, nella funzione onClick() o un elenco di elementi secondari e i relativi gestori di clic.

Dati dei frammenti di contenuto

Il frammento di contenuto attivo può essere recuperato utilizzando getContentFragment() metodo su guestConnection.host.contentFragment oggetto.

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

Il contentFragment L’oggetto contiene tutte le informazioni sul Frammento di contenuto, tra cui il percorso, il modello, i metadati, il contenuto principale ed eventuali varianti.
