This is a memo for when I created a function to load values from a Spreadsheet into the options of a datalist placed in a dialog in Google Slides.
SpreadsheetのA1〜A3にそれぞれ以下の値を入れておきます。
Enter the following values into cells A1 to A3 of the spreadsheet.
A1: option 1
A2: option 2
A3: option 3
Google SlidesのApps Scriptに以下のCode.gsを書きます。
Write the following code in Code.gs in Google Slides Apps Script.
SPREADSHEET_IDは読み込ませたい値が入ったシートのIDに置き換えます。
Replace SPREADSHEET_ID with the ID of the sheet containing the values you want to load.
modalessTemplate() を実行すると、ダイアログに配置したデータリストにシートの値が読み込まれます。
Execute the modalessTemplate() to load those data into a data list placed in a dialog in Google Slides.
リストにない option 4 を入力してsubmitをクリックします。
