Q: JQuery - Bypass AJAX response once request is sent Im using the following way, to request PHP page to send mail to many users. I don't need the response at all. What I want is to just Call the function and start doing my thing in JS.
$.ajax({
  type    : 'POST',
  url     : 'mail_users.php',
  data    : formData,
  dataType: 'JSON',
  encode  : true
})
.done(function(data) {
  console.log(data);
})
.fail(function() {
  console.log("ERROR");
});

I also just want to make sure the request is done properly.
I tried many SO's suggestion like setTimeout() in JS and ignore_user_abort(true), set_time_limit(0) in PHP. 
But nothing worked for me,Is there any right snippet for this?.
How can I achieve this? Thanks in advance.

A: Trying to help. I wrote a code which make a AJAX call to a URL. It contains the callback functions but you can ignore (as you don't wanna check the result). Please, try this code changing the target URL.
