PHPMailer Return To AJAX

Currently I' am setting up a email verification system for my personal site. I (try) to handle this with jQuery and AJAX (code follows). But the problem is that it does not return

Solution 1:

dataType - delete this one.

Add console.log and open console in Your browser

success: function (data) {
   console.log( data );

show Your console, and then You will see why. Maybe an unwanted char or php error

Second thing - there should be if stament like this (I supposed)

if (data == "1") // it is returning string, not integer.

You can also try to use switch case in success.
