global-variables - 我可以从 Jekyll 包含中修改全局 Liquid 变量吗？

Question

我想创建单独的 Jekyll 包含，它们都可以引用相同的公共(public)变量。这是一个简化的场景。

我使用以下 Liquid 代码创建 _include/setter.html:

{% globalString | append: include.add | append: "," %}

然后我使用以下 Liquid 代码创建 _include/getter.html:

we have {{ globalString }}

然后在我的页面中放置:

{% include setter.html add = "one" %}
{% include setter.html add = "two" %}
{% include getter.html %}

我希望看到类似we have one,two, 这样的结果。

当然 globalString 不存在，所以这行不通。我似乎无法在可以从包含中看到的 site 或 page 中创建新变量。现在我笨拙地使用 capture 来解决这个问题。有没有更好的方法将数据传出到 Jekyll 中？

Answer 1

这可以在调用 includes 并将其作为参数传递之前设置全局变量:

_includes/setter.html:

before: {{include.globalString}}<br>
{% assign globalString = include.globalString | append: include.add | append: "," %}
after: {{globalString}}<br>

_includes/getter.html:我们有 {{ include.globalString }}

然后:

{% assign globalString = "" %}
{% include setter.html add = "one" globalString=globalString%}
{% include setter.html add = "two" globalString=globalString%}
{% include getter.html globalString=globalString%}

会输出:

before:
after: one,
before: one,
after: one,two,
we have one,two, 

更新

它也可以在不将“全局”变量作为参数传递的情况下工作，唯一的要求是在调用 includes 之前定义它:

_includes/setter.html:

before: {{globalString}}<br>
{% assign globalString = globalString | append: include.add | append: "," %}
after: {{globalString}}<br>

_includes/getter.html:我们有 {{ globalString }}

{% assign globalString = "" %}
{% include setter.html add = "one" %}
{% include setter.html add = "two" %}
{% include getter.html %}
