jekyll变量，如果函数 [英] jekyll variables, if functions

问题描述

为什么这样的东西不起作用? 我尝试过滤今年的所有帖子

Why is something like this not working ? i try to filter all posts from this year

<div class="tiles">
{% for post in site.categories.articles %}

  {% capture pubyear %} {{ post.date | date: "%Y" }} {% endcapture %}

    {% if pubyear == "2014" %}
      {% include post-grid.html %}
    {% endif %}

{% endfor %}
</div><!-- /.tiles -->

推荐答案

问题是它正在捕获带有一些空格的输出，因此它无法满足if条件，请删除这些空格，然后它应该可以工作

The problem is that it is capturing the output with some spaces in it, so it fails the if condition, remove those spaces and it should work

<div class="tiles"> 
  {% for post in site.categories.articles %}
    {% capture pubyear %}{{ post.date | date: "%Y" }}{% endcapture %} 
    {% if pubyear == "2014" %} 
      {% include post-grid.html %} 
    {% endif %}
  {% endfor %}
</div>
