Working Javascript in HTML rendered notebooks

[Jason]

Is there a way to ensure the javascript components work as per the actual notebooks when the ipynb file has been converted to html?

This seems to be possible from this GitHub directory: https://github.com/jupyter-widgets/ipywidgets/tree/master/examples/web3

How can I replicate this onto my own notebooks?

Hello Jason,

Is there a way to ensure the javascript components work as per the actual notebooks when the ipynb file has been converted to html?

In general? No. JavaScript that relies on data stored in the notebook might work. JavaScript that tries to interact with the running kernel will fail, because there is no running kernel when you browse the html of a converted ipynb file.

 

This seems to be possible from this GitHub directory: https://github.com/jupyter-widgets/ipywidgets/tree/master/examples/web3

Instructions there explicitly mention that a notebook server must be running. This is not the case when you look at the html of a converted notebook. Iirc, ipywidgets/widgetsnbextensions have special logic that allows to render captured output even after conversion of the notebook to html. But you cannot expect the widgets to interact with the code in the kernel, as they do when you are running a notebook.

cheers,

  Roland

Though note that projects like thebelab (https://github.com/minrk/thebelab) are playing around with ways to back a static page with a kernel.

Thanks for the fast replies!

Is is possible to hook the html to a live kernel so that the interactivity is maintained?

If so, how would I go about that?

Regards,

Jason

Hooking an html page to a live kernel is exactly the sort of thing that ThebeLab, the project Chris mentioned, does: https://github.com/minrk/thebelab
