I am trying to create an automatic file download when a visitor submits a validated opt-in form. I would like to initiate the download using a Javascript function as an onsubmit() event. Here is the code I am working with I am already using the form action= to submit the form data to a database and there is already Javascript in place to validate the form. I just need to add the download function.

I want to use onsubmit instead of onclick because I need to make sure that the form has been validated before the file is able to be downloaded.
I am somewhat new to Javascript and have been struggling with this. I would greatly appreciate someone’s assistance. The closest thing I found to an answer can be seen at HTML OnSubmit: Download OR HTML, but since they never gave any code examples it does not help me see the solution.
