google apps script - Limit form responses to once per person....without login? -

i designing test, want people respond test once, without making them log in via google. there way can retrieve ip addresses and/or use cookie limit responses?

no, nonexof wishes possible google forms. in fact forms not support running code during form fill.

your options either host google form in own domain , add custom javascript (not officially supported google it) or somehow filter out responses later (onformsubmit , such based on other unique data in form fields)
