Accessing button attributes and getting URL from CustomJs code

Community Support
1

Hi,
is there any way to access and change button attribute (e.g. name) from CustomJs code? Only solution I’ve found is to send ajax put request. But I need URL for it. In general
window.location.pathname

``

works but I have my widget on Jupyter Notebook and window.location.pathname returns me URL of notebook. So is there any way to get URL of “session” with widget in CustomJs code?
Thanks.

Hi,

Yes. You can pass the button to CustomJS as part it’s args argument and then access it inside the CustomJS javascript code. (more info at the user guide documentation).

As an example of what you are asking for you can see this modified version of the gapminder example .

Cheers

Hi Fabio,
thank you for your help. It works if the button is part of arg. But now I need to handle that change in Python code (button.on_change(…)).
Bokeh.$(‘#button_id’).change();

``

does not work. It works with textinput but not with button. How can I do that?
Thanks

Hi,

Now I’m quite confused about what your use case. Are you using bokeh-server, CustomJS or both? How? Can you provide some more context? Also a code example would help too…

Cheers

Hi,
I’m using Bokeh-server and tap tool. And I need to recognize which coordinates I click on and send that on my Python “app-server” then compute something and send output “back to browser”. So I’m using CustomJs code for tap tool. In JS code I send coordinates through the button attribute “name” (via ajax put request which does not work in Jupyter notebook cause bad URL). In Python code I have button.on_change function which gets coordinates of click. It’s quite weird but I didn’t find another solution.
