updateTextInput(session, inputId, label = NULL, value = NULL)
session
object passed to
function given to shinyServer
.The syntax of these functions is similar to the functions that created the
inputs in the first place. For example, numericInput()
and
updateNumericInput()
take a similar set of arguments.
Any arguments with NULL values will be ignored; they will not result in any changes to the input object on the client.
textInput
shinyServer(function(input, output, session) {
observe({
# We'll use the input$controller variable multiple times, so save it as x
# for convenience.
x <- input$controller
# This will change the value of input$inText, based on x
updateTextInput(session, "inText", value = paste("New text", x))
# Can also set the label, this time for input$inText2
updateTextInput(session, "inText2",
label = paste("New label", x),
value = paste("New text", x))
})
})
