Question

Is it possible to call a js function and pass a variable into nunjucks template..?

         {{ filter }}
            {% set filterParam = orderBy() %}
            {{ filter }}

Answer 1

const env = new nunjucks.Environment(/* ...loaders etc... */);

装载机是什么意思？

Answer 2

To use a function inside a template you should define it as global.

const nunjucks = require('nunjucks');
const env = new nunjucks.Environment(/* ...loaders etc... */); // or nunjucks.configure(...)
env.addGlobal('foo', () => 'OK');

const out = env.renderString(`{{ foo () }}`);
console.log(out);
