分页(Pagination)

With many websites — especially blogs — it’s very common to break the main listing of posts up into smaller lists and display them over multiple pages. Jekyll offers a pagination plugin, so you can automatically generate the appropriate files and folders you need for paginated listings.

For Jekyll 3 or higher, include the jekyll-paginate plugin in your Gemfile and in your _config.yml under plugins. For Jekyll 2, this is standard.

Pagination only works within HTML files

Pagination does not work from within Markdown files from your Jekyll site. Pagination works when called from within the HTML file, named index.html, which optionally may reside in and produce pagination from within a subdirectory, via the paginate_path configuration value.

Enable pagination

To enable pagination for posts on your blog, add a line to the _config.yml file that specifies how many items should be displayed per page:

paginate: 5

The number should be the maximum number of Posts you’d like to be displayed per-page in the generated site.

You may also specify the destination of the pagination pages:

paginate_path: "/blog/page:num/"

This will read in blog/index.html, send it each pagination page in Liquid as paginator and write the output to blog/page:num/, where :num is the pagination page number, starting with 2.
If a site has 12 posts and specifies paginate: 5, Jekyll will write blog/index.html with the first 5 posts, blog/page2/index.html with the next 5 posts and blog/page3/index.html with the last 2 posts into the destination directory.

Don't set a permalink

Setting a permalink in the front matter of your blog page will cause pagination to break. Just omit the permalink.

Pagination for categories, tags and collections

The more recent jekyll-paginate-v2 plugin supports more features. See the pagination examples in the repository. This plugin is not supported by GitHub Pages.

Liquid Attributes Available

The pagination plugin exposes the paginator liquid object with the following attributes:

变量	说明
`paginator.page`	The number of the current page
`paginator.per_page`	Number of posts per page
`paginator.posts`	Posts available for the current page
`paginator.total_posts`	Total number of posts
`paginator.total_pages`	Total number of pages
`paginator.previous_page`	The number of the previous page, or `nil` if no previous page exists
`paginator.previous_page_path`	The path to the previous page, or `nil` if no previous page exists
`paginator.next_page`	The number of the next page, or `nil` if no subsequent page exists
`paginator.next_page_path`	The path to the next page, or `nil` if no subsequent page exists

Pagination does not support tags or categories

Pagination pages through every post in the posts variable unless a post has hidden: true in its front matter. It does not currently allow paging over groups of posts linked by a common tag or category. It cannot include any collection of documents because it is restricted to posts.

Render the paginated Posts

The next thing you need to do is to actually display your posts in a list using the paginator variable that will now be available to you. You’ll probably want to do this in one of the main pages of your site. Here’s one example of a simple way of rendering paginated Posts in a HTML file:

---
layout: default
title: My Blog
---

<!-- This loops through the paginated posts -->
{% for post in paginator.posts %}
  <h1><a href="{{ post.url }}">{{ post.title }}</a></h1>
  <p class="author">
    <span class="date">{{ post.date }}</span>
  </p>
  <div class="content">
    {{ post.content }}
  </div>
{% endfor %}

<!-- Pagination links -->
<div class="pagination">
  {% if paginator.previous_page %}
    <a href="{{ paginator.previous_page_path }}" class="previous">
      Previous
    </a>
  {% else %}
    <span class="previous">Previous</span>
  {% endif %}
  <span class="page_number ">
    Page: {{ paginator.page }} of {{ paginator.total_pages }}
  </span>
  {% if paginator.next_page %}
    <a href="{{ paginator.next_page_path }}" class="next">Next</a>
  {% else %}
    <span class="next ">Next</span>
  {% endif %}
</div>

Beware the page one edge-case

Jekyll does not generate a ‘page1’ folder, so the above code will not work when a /page1 link is produced. See below for a way to handle this if it’s a problem for you.

The following HTML snippet should handle page one, and render a list of each page with links to all but the current page.

{% if paginator.total_pages > 1 %}
<div class="pagination">
  {% if paginator.previous_page %}
    <a href="{{ paginator.previous_page_path | relative_url }}">&laquo; Prev</a>
  {% else %}
    <span>&laquo; Prev</span>
  {% endif %}

  {% for page in (1..paginator.total_pages) %}
    {% if page == paginator.page %}
      <em>{{ page }}</em>
    {% elsif page == 1 %}
      <a href="{{ '/' | relative_url }}">{{ page }}</a>
    {% else %}
      <a href="{{ site.paginate_path | relative_url | replace: ':num', page }}">{{ page }}</a>
    {% endif %}
  {% endfor %}

  {% if paginator.next_page %}
    <a href="{{ paginator.next_page_path | relative_url }}">Next &raquo;</a>
  {% else %}
    <span>Next &raquo;</span>
  {% endif %}
</div>
{% endif %}
