ASK for user guide Callback Javascript

Community Support

Hi guys,

Can you provide user guide about Javascript callback?

I’ve read documentation at Making Interactions — Bokeh 2.4.2 Documentation.

In particular, I’m interested about TapTool, but only given a guide about OpenURL. I don’t see how custom tap callback works.

And how to best explore javascript variable in Jupyter? How to inspect data from cb_obj, and cb_data?

Should I just try to create standalone html file and learn javascript callback from there?

Hi I'm planning to write up quite alot about the BokehJS interface during the 0.12 code freeze. Hopefully 0.12 is only a couple of weeks away.
