將內容片段匯出至XML

內容片段編輯器標題功能表擴充功能範例

可使用headerMenu擴充點將自訂按鈕新增到內容片段編輯器標題功能表中。 此範例說明如何新增按鈕到標題選單,以及如何處理點選事件以將作用中的內容片段匯出為XML或CSV。

頁首按鈕可以單一按鈕的形式存在,也可以作為具有子專案的按鈕存在。 此範例說明如何使用子專案實施按鈕,但包含註釋掉的程式碼以實施單一按鈕。

擴充點

此範例延伸至擴充點headerBar,以將自訂按鈕新增至內容片段編輯器。

AEM UI已擴充

範例擴充功能

下列範例會建立含有兩個子專案的頁首功能表按鈕,其中一個是將作用中內容片段匯出為XML (已實作),另一個是將作用中內容片段匯出為CSV (未實作)。

此程式碼說明如何在擴充功能的註冊檔案中取得內容片段內容,以及如何匯出內容片段的JSON內容。

擴充功能註冊

ExtensionRegistration.js對應至index.html路由,是AEM擴充功能的進入點,並定義:

  • 擴充功能按鈕的位置會顯示在AEM編寫體驗中(headerMenu)
  • getButton()函式中的擴充功能按鈕定義
  • 按鈕的點選處理常式(在onClick()函式中)或子專案清單及其點選處理常式。
