I want to be able to send a JSON dictionary of true or false values from multiple checkboxes. Unfortunately, when I submit, whether checked or unchecked, the values sent to Flask are always "on", not true or false. Can anyone please help? I'd be very grateful.
Here is my HTML/JQuery code
checkbox1.html
