Question

我使用Octopress 2.0进行博客，该博客使用的是Jekyll静态网站生成器。

要标记首页博客文章的摘录，您可以在帖子中插入，直到该点的内容将用作摘录..

对于某些帖子，即使我想要一个摘录，我想要从中排除某些内容（也许是一个只对帖子有意义的目录，或者对摘录有用的一些额外的注释））。

在Octopress / Jekyll / Liquid中是否有办法使用方法生成摘录，但是还标记了一些少量内容要被遗漏？

这是一个简短的例子。接受这篇文章：

---
layout: post
title: "Example Post"
---

This is the first paragraph. It will be included in the excerpt.

[Jump to third paragraph](#para3). This paragraph should **not** be in the excerpt.

This is the second paragraph. It will be included in the excerpt.

<!--more-->

<a name="para3"></a>This is the third paragraph. It won't be in the excerpt.

我想要一种方法让这篇文章的摘录为：

This is the first paragraph. It will be included in the excerpt.

This is the second paragraph. It will be included in the excerpt.

Answer 1

修改：我现在明白你要做的是什么。

我假设你使用默认的章鱼降价：rdiscount 。

让我们得到过滤方式：

在 Gemfile 中添加gem 'nokogiri'

在你的帖子中，我们的想法是将span.secondary添加到有时被剥离的部分。含量

...
remove_secondary_content_from_excerpt : true
---
This is the first paragraph. It will be included in the excerpt.

[[Jump to third paragraph](#para3). This paragraph should **not** 
be in the excerpt.](class:secondary)

This is the second paragraph. It will be included in the excerpt.

### This is the TEXT title
This is **the text**

在_includes / article.html

中

...
  </header>
{% endunless %}
{% if index %}
    <div class="entry-content">
        {% if post.remove_secondary_content_from_excerpt == true %}
        {% capture secondary_content %}{{ post.excerpt | excerpt_get_secondary_content }}{% endcapture %}
        {{ post.excerpt | remove: secondary_content }}
        {% else %}
        {{ post.excerpt }}
        {% endif %}
    </div>
  {% capture excerpted %}{{ content | has_excerpt }}{% endcapture %}
  {% if excerpted == 'true' %}
    <footer>
      <a rel="full-article" href="{{ root_url }}{{ post.url }}">{{ site.excerpt_link }}</a>
    </footer>
  {% endif %}
{% else %}
<div class="entry-content">
    <!-- example on how to use it in post page -->
    {% if page.remove_secondary_content_from_excerpt == true %}
        {% capture secondary_content %}{{ page.excerpt | excerpt_get_secondary_content }}{% endcapture %}
        {{ page.excerpt | remove: secondary_content }}
        {{ secondary_content }}
        {{ page.content | markdownify | remove: page.excerpt }}
    {% else %}
        {{ content }}
    {% endif %}
</div>
{% endif %}

在_plugins / octopress_filters.rb

中

...
module OctopressLiquidFilters

  def excerpt_get_secondary_content(input)
    require 'nokogiri'
    doc = Nokogiri::HTML(input)
    # as excerpt can surrounded by one <p> (when no double newline in it)
    # or with multiple <p> when a double newline is found
    multiparagraph = doc.css("p").length > 1

    if multiparagraph
      # look for parent <p>
      xpathString = "span.secondary/.."
    end
      # look only for the span element
      xpathString = "span.secondary"
    else

    secondary = doc.css(xpathString)
    secondary.to_s
  end

...

安装Nokogiri bundle update

我跳你的rake generate会让你开心。

如何省略Octopress / Jekyll提取的摘录中的内容？
