建立用戶端程式庫

AEM用戶端程式庫會管理所有用戶端JavaScript程式碼。 針對本文,我已建立簡單的JavaScript,以使用指南橋接器API擷取適用性表單資料。 擷取適用性表單資料後,會對servlet發出POST呼叫,以在資料庫中插入或更新適用性表單資料。 函式getALLUrlParams會傳回URL中的參數。 如果URL中存在guid參數,則需要執行更新操作(如果不是插入操作)。其餘功能在與.savebutton類的點擊事件關聯的代碼中處理。

        // split our query string into its component parts
        var arr = queryString.split('&');
