crosstalk.FilterHandle doesn't return the same type consistently
daattali opened this issue · comments
When a filter_select() is used, the FilterHandle callback returns the keys as a string array. When a filter_slider() is used, a numeric array is returned.
Example:
library(shiny)
df <- data.frame(id = 1:5, num1 = 11:15, num2 = 21:25)
shared_df <- crosstalk::SharedData$new(df, key = ~id, group = 'test')
ui <- fluidPage(
crosstalk::filter_select("num1", "num1", shared_df, ~num1),
crosstalk::filter_slider("num2", "num2", shared_df, ~num2, step = 1),
tags$script(HTML(
'ctFil = new crosstalk.FilterHandle("test");
ctFil.on("change", function(e) { console.log(e.value); });'
))
)
server <- function(input, output, session) {}
shinyApp(ui, server)Make selections using either filter, and look at the javascript console.
