Cannot generate .html from ipynb with Jupyter state JSON including `</script>` #8433

The problem, specifically, is that pyvista is emitting a widget state that includes the specific string </script>. We are following the recommended approach here: https://ipywidgets.readthedocs.io/en/7.x/embedding.html which is to create a script tag and embed the JSON text.

We do that. Unfortunately, this widget state cannot have the </script> string, because that causes the outer <script type="application/vnd.jupyter.widget-state+json"> to close.

In my original comment, I wrote:

If ipywidgets allows us to emit this JSON in an escaped way so that it can have the string </script> in it, then we can fix the bug on our side (but I can't see a way to do that in the documentation). But unfortunately this looks like something we can't fix on our side.

But I think I know a way around it. Here's a funny way to create a script tag with the string </script> inside it:

<html>
<head>
    <script>
        const scriptTag = document.createElement('script');
        scriptTag.type = "application/json";
        scriptTag.innerText = JSON.stringify({
            "src": "<script></" + "script>"
        });
        document.head.appendChild(scriptTag);
    </script>
</head>
<body>
</body>
</html>

So we can adapt this to create a script tag that self-expands into a JSON script tag that safely contains the string </script>.

The text was updated successfully, but these errors were encountered:
