I wasn’t sure if I should start a new topic on this or not. But I’m stuck again this time on returning a javascript variable back to dash. my javascript looks like this $('div[id^=row]').click(function(){ var rowId = $(this).closest('div').attr('id'); Shiny.onInputChange("catSelec…

[image] residnt: But I’m stuck again this time on returning a javascript variable back to dash. The only way to do this right now is through the official Dash plugin system: Build Your Own Components | Dash for Python Documentation | Plotly . You can write a custom component in JavaScript with…

I’m investigating using the n_clicks property based on the example you have posted here is-there-a-way-to-only-update-on-a-button-press-for-apps-where-updates-are-slow However what isn’t clear at the moment is how do I know what div to target as the input since the id’s are generated during the in…

[image] residnt: unless what you are saying is I need to create a callback for each iteration Yeah, (for now) you need to create a unique callback for each unique ID. See Callback for Dynamically created Graph - #4 by chriddyp

So here is where I’m heading so far which I don’t know if this is going to work. To test this out I’ve created a div called clicked and clickedvalue html.Div('Nothing has been clicked', className = 'row', id = 'Clicked'), html.Div(className = 'row', id = 'ClickedValue') I’m using this jav…

[image] residnt: What I’m still trying to figure out is if I can read in this updated value with this call back It looks like you have multiple click events on the same element - Dash is listening for a click event (see dash-html-components/src/components/Div.react.js at 6d04a70f098bb86405454…

Maybe this can explain it a little better http://recordit.co/cCporQFQaW so the div the gets updated with row_#_# is the clicked div the div that stays Nothing has been selected is the ClickedValue div. So from what I understand is ClickedValue isn’t being updated because Clicked isn’t actually s…

[image] residnt: So from what I understand is ClickedValue isn’t being updated because Clicked isn’t actually sending a clicked event. Yeah, it could be that your click handlers are masking the existing click handlers in the React component.

so here is something interesting. Doing this callback @app.callback( Output('ClickedValue', 'children'), [Input('Clicked', 'n_clicks')], state=[State('Clicked', 'children')] ) def update_output_div(n_clicks, Clicked): return '{} but clicked {} times'.format(Cli…

Ok, I’m bringing up my old thread as I didn’t really want to start a new one for this. I’ve been looking at generating my own component, actually I just wanted to modify the existing div in this instance to see if I can create a new prop call n_id to return the div id on the fire event. However I’…

Hey residnt, Did you solve this? I am trying to do this as well i.e. bridge two apps. I would appreciate any help. Did you manage to create a component?
