This function must be called from a Shiny app's UI in order for all other
shinyjs
functions to work.
You can call useShinyjs()
from anywhere inside the UI, as long as the
final app UI contains the result of useShinyjs()
.
useShinyjs(rmd = FALSE, debug = FALSE, html = FALSE)
rmd | Set this to |
---|---|
debug | Set this to |
html | Set this to |
Scripts that shinyjs
requires that are automatically inserted
to the app's <head>
tag. A side effect of calling this function is that
a shinyjs
directory is added as a resource path using
addResourcePath.
If you're a package author and including shinyjs
in a function in your
your package, you need to make sure useShinyjs()
is called either by
the end user's Shiny app or by your function's UI.
if (interactive()) { library(shiny) shinyApp( ui = fluidPage( useShinyjs(), # Set up shinyjs actionButton("btn", "Click me"), textInput("element", "Watch what happens to me") ), server = function(input, output) { observeEvent(input$btn, { # Run a simply shinyjs function toggle("element") }) } ) }
