Change the value of a text input on the client

Change the value of a text input on the client

updateTextInput(session, inputId, label = NULL, value = NULL)

The input updater functions send a message to the client, telling it to change the settings of an input object. The messages are collected and sent after all the observers (including outputs) have finished running.

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.

    # 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))
