目標
- 瞭解解決方案的功能。
- 瞭解解決方案中的 Apps Script 服務功能。
- 設定指令碼。
- 執行指令碼。
認識這項解決方案
使用這項解決方案,在簡報投影片底部新增進度列。

運作方式
這個指令碼會計算簡報中的投影片數量,並在每張投影片底部新增矩形。這項指令碼會增加每個矩形圖案的寬度,在投影片中顯示進度。
Apps Script 服務
這項解決方案會使用下列服務:
- 簡報服務:取得簡報的投影片,並在每張投影片中新增矩形。
必要條件
如要使用這個範例,您必須符合下列先決條件:
- Google 帳戶 (Google Workspace 帳戶可能需要管理員核准)。
- 可連上網際網路的網路瀏覽器。
設定指令碼
- 點選下列按鈕,複製「進度列」投影片簡報。這項解決方案的 Apps Script 專案已附加至簡報。
建立副本
- 在簡報中,依序點選「擴充功能」>「進度列」>「顯示進度列」。
出現提示訊息時,請授權執行指令碼。如果 OAuth 同意畫面顯示「這個應用程式未經驗證」警告,請依序選取「進階」>「前往『{專案名稱}』(不安全)」,繼續操作。
再次依序點選「擴充功能」>「進度列」>「顯示進度列」。
如要移除進度列,請依序點選「擴充功能」>「進度列」>「隱藏進度列」。
