Js_event_callbacks with customjs

[ahmettemiz88]

Hi,
Can I use js_event_callbacks with callback that is created by customjs ?

Regards

js_event_callbacks is not really intended for users to use directly. It is only a “public” property due to some other unrelated (and uninteresting) technical limitations. Please describe what it is you are actually trying to accomplish at a high level (i.e. without assuming any kind of implementation details) and then folks here can offer guidance.

Hi
Here is my related code that was working normally in Bokeh2.2

code = '  if ( (range_slider.value[0]==0.0) && (range_slider.value[1]==0.85) )
      { alert("Öncelikle Kaydırma Çubuğu ile Tehlike Aralığı Belirleyiniz !");
 } '

critical_selection.js_on_click(CustomJS(args={'chck_group': critical_selection,'range_slider':range_slider }, code=code))

bokeh3.2.1 complained as : ```
File “/app/main.py”, line 1316, in
critical_selection.js_on_click(CustomJS(args={‘chck_group’: critical_selection,‘range_slider’:range_slider }, code=code))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

@ahmettemiz88 in the future please use proper code formatting (either with the </> icon on the editing toolbar, or triple backtick ``` fences around the code blocks)

js_on_click was remove at Bokeh 3.0. There is not enough information above to provide any guidance (without guessing, which I am not going to do). What exact kind of widget is critical_selection and what kind of interaction are you trying to achieve (described from the user perspective)?

Otherwise all I can do is mention in general that the only two relevant APIs are now:

• js_on_change for responding to property changes
• js_on_event for responding to various UI events

There is much documentation and examples of both:
