how to keep double quotes in twig?

Question

I have a json array that I pass to the twig template, but the double quotes in the array have been causing trouble, my json array is like this:

$arr = json_encode(array("a", "b")); // which prints out ["a", "b"]

in twig template, I print it out like this:

attrs: {{ arr }}

I expect it to be attrs: ["a", "b"] , however, what gets output is attrs: ["a", "b"] , I tried attrs: {{ arr|e('js') }} , but no luck, my js lib just says there are some unrecognised characters. So how do I get intended attrs: ["a", "b"] ?

Many thanks!

Answer 1

Sounds like you have auto-escaping on. (e: which is a good thing)

Have you tried {{ arr|raw }} ?

Answer 2

如果需要，可以使用 twig 中的escape过滤器将双引号显示到 javascript 中。

{{ array|json_encode|raw|escape('js') }}
