Add Blogspot Page Number 部落格页数

一般上，Blogger 的 Blogspot 底下并没有部落格页数。

Blogspot 底下一般上只有 “Home” 跟 “Older Post”，所以如果我们想看回之前的博文或部落格文章，那么只能一直按 “Older Post”。

 

现在有方法让我们可以在部落格底下增加页数 – Add Blogspot Page Number（如上图 1）。

要如何在 blogspot 部落格加上页数 Page Number呢？

1. Login Blogger > Design
2. Page Element > Add a Gadget （普通加入 Gadget 的方法）
3. 选择 Add Html / Javascript

把以下的 code 放入 这个 Gadget 就可以了。

[sourcecode language=”xml”]

<script type=”text/javascript”>// <![CDATA[

加入这个 code 后，我们在把这个 Gadget 拖曳到主要Blog post 底下（如下图）。大功告成。

注意：你部落格的封面 Main Page有多少个 Post 同时出现？Blogspot 的原本设定为 7个。如果你的已经把设定更改了，那么请改一改这个 code 。

[sourcecode language=”xml”]var pageCount = 7;[/sourcecode]

把 7 改成你的设定。
