laravel | ajax, if form incomplete send email - html

Question

Hello fellow developers,
I am trying to solve a problem I am having and can't seem to find the correct answer a possible link or explanation will be very helpful.
I want to add an ajax function on the email field once the email is entered the name, surname and email should be saved to the database without the submit button being pressed. So that a (complete your form) email can be send 2 hours later.
I am really new to ajax and already using parsley for front end verification
Would anybody be able to assist?
Regards
