I'm creating a survey with Google Forms.   I need to know when the user is done with the survey so that I can have them continue on my site.  I have embedded the survey as an Iframe on my website.Is there a way to:Use JavaScript to interact with the form so that my page gets an event when the form is completed?Put a link on the form that the user can click on when they are done to go to a thank you page on my site?Some other way of getting knowing that this user has completed the survey?I'd think there would have to be a way to do this, but I can't seem to find it.   If it isn't possible, I'd like to know that so that I can stop wasting my time and use another product like SurveyMonkey.
Can I tell when a user is done filling out a Google Form?
