如何使用 Google Forms 预提交执行 email 验证

Question

I am autogenerating some Google Forms which have the automatic email collection field enabled. I would like to make it so that each of them can only be submitted by certain emails. As such, I would like to check that the auto-collected email is an allowed email address before they submit the Form.

I would prefer not to use a regular textbox that says "enter email here", because then any user who opens the form could input an email which may not be their own.

I know I can check the email is correct after the Form is submitted, but I would prefer to do it before.

Is this possible?

Answer 1

Currently, it seems there is no way to validate automatically collected email before form submission.
