Nice finding, David. I've come across that in the context of Koha and Template::Toolkit, and did something similar, using a data- attribute. I used [% USE JSON.Escape %] to escape the data that comes from Perl.

Here, I set the data structure to a data-pickup-locations attribute:

And then I use it:

Best regards

Hi all,

I was just reflecting on bugs like https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=26942 and reviewing https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script when I saw the following method for embedding JSON in HTML:


<script id="data" type="application/json">{"userId":1234,"userName":"John Doe","memberSince":"2000-01-01T00:00:00.000Z"}</script>


<script>
const userInfo = JSON.parse(document.getElementById("data").text);
console.log("User information: %o", userInfo);
</script>

I thought that was neat.
