Hi, first time developing on Discourse, so sorry for the silly questions. I’m building a theme component to display PGNs (chessboard and matches). The component is not theoretically difficult, there is a js component for this (PGNViewer.js) and I was able to translate the [wrap] tags into the prop…

debounceFunction delay calling the target method until the debounce period has elapsed with no additional debounce calls, it sometimes won’t work may still because [圖片] HappyCactus: the document is not yet populated and the PGNV object is unable to find the block debounce may not be the solu…

Welcome to Meta, @happycactus :wave: [圖片] HappyCactus: Overall, is this approach correct, or would it be better to implement a plugin instead? Yes, probably. The only reason why you’d need a plugin is if you were trying to change the API (ie back end). [圖片] HappyCactus: I can’t on my p…

Thank you, Robert! I’m in doubt, probably because I’ve zero experience with such platforms. My doubt is: my approach is to “embed” the small snippet of javascript needed to fill the div block with the content, but I see that maybe I could execute it from a function “cookPgn”, like it is done in t…

[圖片] HappyCactus: what’s the difference between the loadScript and a simple import? Have you tried an import? I don’t think you can import an external script. Loadscript is the right approach and ensures that the script is fully loaded before your code proceeds and uses it (this is why it r…

Your actual problem is trying to use inline JS, which is prohibited by CSP. [圖片] HappyCactus: <script>var x='pgn here'; ...</script> Put this code in a helper function in your theme component code, and do not inject it inside posts. Uploading your current theme to GitHub and we can take a l…

Have a look at the Discourse Mermaid component, which loads a library and has stuff happen to posts.

[圖片] Falco: Your actual problem is trying to use inline JS, which is prohibited by CSP. Thanks, @Falco , this was one of my doubts. [圖片] Falco: Uploading your current theme to GitHub and we can take a look too. Sure, here it is: GitHub - studiofuga/discourse-pgn-component: A theme comp…

[圖片] Robert: [圖片] happycactus: I can’t on my production server, because it says the asset is too big. Is there a way to fix this? I’ve had a similar issue in the past. My fault, I forgot I limited the attachment size to 512kB, raised to default (4096) and it worked well. Thanks, and so…

Ok I did fix everything and the component does work! But we have a problem, an “unsafe eval” in the library I’m using. I guess I should fix the upstream library, I have no idea how to pack it. For those interested, I pushed all my changes in my repo above, and here are the details of the error. […

Your script is tripping over Content Security Policy in Production. You need to add 'unsafe-eval' as a line item in the site setting: content security policy script src

Thanks, I’m browsing the documentation to see how to do this. :slight_smile: I’m learning a lot, thanks

看看 Discourse Mermaid 组件，它会加载一个库并对帖子执行一些操作。
