找到2个具有非唯一ID的元素＃billing-new-address-form Magento 2

在结帐页面上，当选择送货方式并转到下一步“付款”时，我收到以下控制台错误。

[DOM]找到了两个具有非唯一ID＃billing-new-address-form的元素：

[DOM]找到了两个具有非唯一ID＃billing-save-in-address-book的元素：

我该如何解决这个问题？

此问题已在2.3-develop分支中修复，也已向后移植到2.2，并将在2.2.6中发布，我也看到它也已向后移植到2.1。

有2个地方需要更改以解决此问题

干杯

如果您想解决问题，请执行以下步骤

1. 首先在.phtml文件中找到该html所在的位置
2. 现在用循环（for，foreach）分析任何获取数据的对象
3. 如果数据与该ID一起循环，则添加一些唯一数据

像这样

<?php
foreach ($variable as $key => $value) {
 ?>
      <div id="billing-new-address-form<?php echo "-"."daynamic some unique id"; ?>"></div>
 <?php
}
?>

和uniq id已生成
