液体for循环能否在Jekyll中包含页面变量? [英] Can a liquid for loop contain a page variable in Jekyll?

问题描述

比方说，我有一堆_data文件，可用于创建特定页面的列表.具有这些列表的所有页面的自定义前端变量为pageName. pageName的值恰好与_data文件与列表匹配.

Let's say I have a bunch of _data files that I use to create a list for specific pages. All of the pages that have these lists have a custom front matter variable of pageName. The value of pageName just so happens to match the _data file with the list.

我不想使用html代码块粘贴到每个页面中，而是想使用include提取通用html代码块.为此，包含必须动态或包含液体标记才能动态.

Rather than pasting the html blocks of code into each page, I'd like to use an include to pull in a generic block of html. To do that, the include has to be dynamic or contain liquid markup to become dynamic.

这可能是您需要的更多上下文，但是我的问题归结为这一点，这可能是这样的:

That might be more context than you need, but my question boils down to this, is something like this possible:

{% for item in site.data.{{page.pageName}} %}
  {{ item.label }}
{% endfor %}

除非我丢失了某些东西，否则这将无法正常工作，因此我想知道是否存在一种实现类似功能的方法.

Unless I'm missing something, this doesn't work so I'm wanting to know if there's a way of achieving similar functionality.

我发现了这个类似的问题，但是似乎并没有回答它是否可用于访问页面变量以构建文件名.

I found this similar question, but it doesn't seem to answer whether it can be used to access a page variable to build a file name.

推荐答案

您可以使用像这样的方括号表示法:

You can use the bracket notation like this :

{% for item in site.data[page.pageName] %}
