我不是开发人员，我从事营销工作，但对 HTML 等有一些了解，
我们的博客文章索引页有问题。当我们发布了 9 个以上的博客时，会触发一个加载更多按钮。然后它加载下面的其他博客，似乎没有限制加载下面的显示数量，所以我假设它设置为加载所有剩余的博客。但是，当您单击加载更多时，它不仅会显示其他博客，而且还会一次又一次地复制相同的博客字符串，然后显示另一个加载更多按钮，重复的过程再次发生。
我一直在查看我们的函数文件、blog-index 和 myloadmore.js.txt，但根据我在各种论坛上阅读的内容，我看不出问题出在哪里。
在检查博客索引页面并查看网络选项卡时，它似乎确实加载了两次 admin-ajax.php 文件。同样在控制台选项卡上 myloadmore.js?ver=5.7:13 显示多次。不确定这是否是一个问题，以及这是否有助于突出问题？
如果能提供一些帮助，我将不胜感激，但请记住，这不是我的专业领域，因此您可能需要用更简单的术语来解释我需要去哪里以及我需要更改什么才能解决问题。< /p>
这是我的 blog.index：
