我正在使用omnisend应用程序进行Shopify订阅列表。我正在使用自定义表单来集成输入数据。 对于ominsend形式，它们具有自己的类来捕获数据。 像这样：

<form class="my-form omnisend-subscribe-form" action="/subscribe" method="post">
    <input class="omnisend-subscribe-input-email" type="text" placeholder="Enter your email address" />
    <input class="omnisend-subscribe-input-first-name" type="text" placeholder="Enter your first name" />
    <input class="omnisend-subscribe-input-last-name" type="text" placeholder="Enter your last name" />
    <input type="submit" value="Subscribe!">
</form>

名字： omnisend-subscribe-input-first-name
姓氏： omnisend-subscribe-input-last-name
电子邮件： omnisend-subscribe-input-email

但是对于生日输入数据，我无法找到课程。 如何按班动态调整生日输入数据？

<form class="my-form omnisend-subscribe-form" action="/subscribe" method="post">
    <input class="omnisend-subscribe-input-email" type="text" placeholder="Enter your email address" />
    <input class="omnisend-subscribe-input-first-name" type="text" placeholder="Enter your first name" />
    <input class="omnisend-subscribe-input-last-name" type="text" placeholder="Enter your last name" />
    <input class="omnisend-subscribe-input-?" type="text" placeholder="MM" />
    <input class="omnisend-subscribe-input-?" type="text" placeholder="DD" />
    <input class="omnisend-subscribe-input-?" type="text" placeholder="YYYY" />
    <input type="submit" value="Subscribe!">
</form>
