I want to know whether its possible to display a dialog box popup after submitting google forms. Just before the screen in which a confirmation screen is displayed that your request has been recorded.
I checked this post in which onOpen event of spreadsheets is used to display a popup. How do I open a web browser using google apps script?.
Can i do the same onFormSubmit event of spreadsheet. If it's possible than how to do this because I am new to google app script. My requirement is to use fileUpload with google forms. After user submits the forms a dialog should appear asking user if he/she wants to upload a file. Thanks.
