concat 连接合并数组

将多个数组连接（合并）在一起。合并后的数组包含所有输入数组中的项。

输入

{% assign fruits = "apples, oranges, peaches" | split: ", " %}
{% assign vegetables = "carrots, turnips, potatoes" | split: ", " %}

{% assign everything = fruits | concat: vegetables %}

{% for item in everything %}
- {{ item }}
{% endfor %}

输出

- apples
- oranges
- peaches
- carrots
- turnips
- potatoes

你可以连续使用多个 concat 过滤器来连接两个以上的数组。

输入

{% assign furniture = "chairs, tables, shelves" | split: ", " %}

{% assign everything = fruits | concat: vegetables | concat: furniture %}

{% for item in everything %}
- {{ item }}
{% endfor %}
