液体是否含有“不含"?或“不在阵列中"操作员? [英] Does Liquid have a "does not contain" or "not in array" operator?

问题描述

在Liquid模板中调用项目和数组中的项目时，如何调用does not contain或not in array?

When calling items from and array in a Liquid template, how do you call does not contain or not in array?

推荐答案

unless进行救援！

创建[A，B，C]数组.

Create an [A, B, C] array.

{% assign input = "A,B,C" | split:"," %}

unless仅在不满足约束条件时打印.

unless print only if constrain is not met.

这不会打印任何内容:

{% unless input contains 'A' %}No A{% endunless %}

这会显示"没有Z ":

{% unless input contains 'Z' %}No Z{% endunless %}
