How to update button labels in R Shiny?

Question

The R Shiny website has a great example of how to update the labels and values of a variety of input types based on user input. However, I couldn\'t find anything for butto

Answer 1

If your button is already built, the solution is to use library "shinyjs".

library(shinyjs)
 # in UI section
shinyjs::useShinyjs()
 # in Server section: call this function at any time to update the button label
runjs(paste0("$('label[for=\"YourButtonId\"]').text('",TextVariable,"')"))
