Send a mail on closing the browser tab

Question

I am currently working on a multistep form, and it has around 100 fields.

Suppose a user start filling the form and completed 30 fields and get harrased. And suddenly the user closes the tab, then a pop up should open as shown in the image below.

Now user enter the email address in a pop up form, and on clicking button, a mail will be send with all the filled values (ie 30 fields value).

Is this possible in some other way or this way...Thank you.

Answer 1

Use jQuery's window.unload : https://api.jquery.com/unload/

Make a call to the server through jQuery's $.post , and serialize the form data. You'll have to manage the data on the server.
