javascript - Mailchimp Ajax 重定向

Question

所以我尝试使用 MailChimp 和 Ajax 创建一个简单的时事通讯注册来在后台处理事件。我的问题是它重定向到包含当前代码的页面。我怎样才能修复它，以便在完成后它只显示复选标记而不显示其他内容？我知道动画代码不在正确的位置，它就在那里，所以我可以在重定向之前看到它。

var subscribe_button = document.querySelector(".fi-mail");

subscribe_button.addEventListener('click', function(){
	document.getElementById('ava-subscribe-form').submit();
  subscribe_button.classList.remove("fi-mail");
  subscribe_button.classList.add("fi-check");
});

function register($form) {
    $.ajax({
        type: $form.attr('method'),
        url: '//https://fulfillingtheprophecy.us16.list-manage.com/subscribe/post&id=0ae3f9ab0f&c=?',
        data: $('#ava-subscribe-form').serialize(),
        dataType: 'json',
        cache       : false,
        contentType: "application/json; charset=utf-8",
        error       : function(err) { alert("Could not connect to the registration server. Please try again later."); },
        success     : function(data) {
            if (data.result != "success") {
              alert(data.msg);
            } else {
                // It worked, carry on...
            }
        }
    });
}

$(document).ready( function () {
    var $form = $('ava-subscribe-form');

    if ( $form.length > 0 ) {
        $('form input[type="submit"]').bind('click', function ( event ) {
            if ( event ) event.preventDefault();
              register($form);
        });
    }
});

Answer 1

原因是您将 jquery 事件附加到错误的目标。
您可能会得到如下代码的预期结果。

html:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form method="POST" id="ava-subscribe-form">
  <input type="hidden" name="u" value="9c9cbcbf400c4df4622eef40f">
  <input type="hidden" name="id" value="0ae3f9ab0f">
  <input type="email" placeholder="ava@example.com" autocapitalize="off" autocorrect="off" name="MERGE0" id="MERGE0">
  <a href="javascript:void(0)" class="fi-mail"></a> 
</form>

js

/* moved these code to jquery click
var subscribe_button = document.querySelector(".fi-mail");

subscribe_button.addEventListener('click', function(){
  document.getElementById('ava-subscribe-form').submit();
  subscribe_button.classList.remove("fi-mail");
  subscribe_button.classList.add("fi-check");
});
*/

function register($form) {
    $.ajax({
        type: $form.attr('method'),
        url: 'https://fulfillingtheprophecy.us16.list-manage.com/subscribe/post-json?&c=?',
        data: $('#ava-subscribe-form').serialize(),
        dataType: 'json',
        cache       : false,
        contentType: "application/json; charset=utf-8",
        error       : function(err) { alert("Could not connect to the registration server. Please try again later."); },
        success     : function(data) {
            if (data.result != "success") {
              alert(data.msg);
            } else {
