从博客帖子中检索内容以使用特定标签帖子在主页上显示

Question

我正在显示主页上特定标签的帖子。

然后，在其中，我必须为该标签的每个特定帖子显示更多信息。如下图所示 -

我不是专家，但我认为我们可以使用JavaScript。通过在撰写每个帖子时应用参考代码或变量，例如： -

var / code 要从此帖子检索标签帖子下的主页的一些文字 var / code ]

并使用javascript检索它以显示在主页上的特定标签帖子上

仍然没有找到任何线索我怎么能这样做...请给我任何建议。

这是在主页上显示特定标签的代码：

<script type='text/javascript'>
