如何在Nunjucks中进行不区分大小写的字符串比较 [英] How to do case insensitive string comparison in Nunjucks

问题描述

我正在尝试在 {％if％} 语句内进行不区分大小写的匹配

I'm trying to do a case insensitive match inside of an {% if %} statement

以下两种方法不起作用：

{% set role = 'APP' %}

{% if 'app' == role %}  1 {% endif %}
{% if 'app' in role  %} 2 {% endif %}

Nunucks的比较运算符，但未引用特定类型。

Nunucks only has a little documentation on their comparison operators, but don't refer to specific types.

Nunjucks是Jinja2的端口，并且在如何在Jinja2中小写字符串有类似问题

Nunjucks is a port of Jinja2 and there is a similar question on how to lowercase a string in Jinja2

推荐答案

您可以使用内置过滤器，例如 lower 来转换字符串或nunjucks允许您在表达式内部执行一组有限的JavaScript，因此调用 toLowerCase（）也可以。

You can use one of the built in filters like lower to transform the string or nunjucks allows you to execute a limited set of JavaScript inside of expressions so calling toLowerCase() will also work.

以下三种方法中的任何一种都可以工作：

Any of the following 3 approaches will work:

1 {％if'app'== role.toLowerCase（）％} 1 {％endif％}

2 {％如果'app'==角色|较低的％} 2 {％endif％}

3 {％set role_lower =‘App’|较低的％} {％，如果是 app == role_lower％} 3 {％endif％}
