Question

我想创建单独的Jekyll包含，它们都可以引用相同的公共变量。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 }}

然后在我的页面中我说：

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

我希望看到类似we have one,two,的结果。

但当然globalString不存在，所以这不起作用。我似乎无法在site或page中创建可从包含中看到的新变量。现在我用capture笨拙地解决这个问题。有没有更好的方法在Jekyll中传递包含 out 的数据？

可以在调用 includes 之前设置全局变量并将其作为参数传递来完成：

_includes / setter.html ：

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

_includes / getter.html ：we have {{ 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%}

输出：

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

它也可以在没有通过＆＃34;全球＆＃34;变量作为参数，唯一的要求是在调用 includes ：

之前定义它

<强> _includes / setter.html ：

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

_includes / getter.html ：we have {{ globalString }}

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

我可以在Jekyll包含内修改全局Liquid变量吗？
