Answer 1

使用一个标志，进行检查并将其设置为false

let shouldAjax = true;

// later
if (shouldAjax) {
  $.ajax({
    type: "POST",
    url: "/php/auth/login.php",
    data: $("#login-form").serialize(),
    success: function(msg) { //stuffs 

    },
    complete: function() {
      $(this).data('requestRunning', false);
      shouldAjax = false;
    }
  });
}
