Interacting with the Jupyter widgets

[Christopher Brooks]

Hi,

I'm looking to interact with the jupyter notebook pages in javascript, largely to do things like send key commands. I've spent a bit of time going through the variety of bindings, but I can't see where I could actually raise a keypress/keydown event such that it would trigger KeyboardManager.prototype.bind_events.

Any hints on where I should be looking? My javascript's gotten a bit rusty :)

May I ask what keypresses do you want to trigger, and why? Since keyboard shortcuts are customizable, triggering a keypress in command mode can take an arbitrarily different action from the default behavior, so perhaps calling the js APIs that those keypresses correspond to is the right approach, rather than triggering events that may or may not do what you want.

I actually want to automate the typing of the content out based on a script - I won't be in command mode at the time.

Regards,

Chris

Chris,

Like Min suggests, you'll want to invoke actions instead of emulating keyboard commands.  Similarly, when interacting with widgets and cells, you'll want to invoke the native methods of the objects to set content.  IIRC for a cell it's something like 

cell.set_value('#Cell content') 

- use the web console to find the exact method name.  For widgets 

widgetView.model.set('value', 'something');
widgetView.touch();

There isn't a way to invoke keyboard/mouse click events on cells&widgets that works universally.

Best,

Jon
