我正在用phpmailer发送电子邮件，当我按下；发送（&Q）；按钮，但我想保持在相同的HTML页面上，所以我将AJAX脚本与HTML和PHP结合使用。问题是，我没有得到用电子邮件状态和PHP响应更新HTML页面所需的JSON数据，因此：

感谢您的帮助

HTML中的AJAX

<script>
        $("#form").submit(function(e) {
        e.preventDefault(); // prevent actual form submit
        var from_name_temp = $(\'#from_name\').val();
        var from_email_temp = $(\'#from_email\').val();
        var choix_gout_temp = $(".choix_gout:checked").val();
        $.ajax({
            type: "POST",
            url: "/mailer.php",
            data: "from_name="+from_name_temp+"&from_email="+from_email_temp+"&choix_gout="+choix_gout_temp,
            dataType: "json",
            complete: function(data) {
                    console.log("Thank you for subscribing!");
                    console.log(data);
                    console.log(data.status);
                    console.log(data.message);
                    console.log(data.success);
                }
        })
