在此代码提交后如何添加重定向URL

Question

我正在使用https://emailoctopus.com/，而不是显示消息，我想将用户重定向到特定的URL，而不是在成功提交表单后显示消息。

<link rel="stylesheet" href="https://emailoctopus.com/bundles/emailoctopuslist/css/formEmbed.css">
<div class="email-octopus-form-wrapper">
    <h2 class="email-octopus-heading">h2</h2>
    <p class="email-octopus-success-message"></p>
    <p class="email-octopus-error-message"></p>
    <form method="post" action="https://emailoctopus.com/lists/xxxxxx-4908-11e9-a3c9-06b79b628af2/members/embedded/1.3/add" class="email-octopus-form" data-sitekey="xxxxxx-ovRsPIJ_IftyivYBBhGvRV6">

        <div class="email-octopus-form-row">

            <!-- Do not remove this field, otherwise you risk bot sign-ups -->
