passwordInput: Create a password input control

In shiny: Web Application Framework for R

Create a password input control

Description

Create an password control for entry of passwords.

Usage

passwordInput(
  inputId,
  label,
  value = "",
  width = NULL,
  placeholder = NULL,
  ...,
  updateOn = c("change", "blur")
)

Arguments

inputId	The input slot that will be used to access the value.
label	Display label for the control, or NULL for no label.
value	Initial value.
width	The width of the input, e.g. '400px', or '100%'; see validateCssUnit().
placeholder	A character string giving the user a hint as to what can be entered into the control. Internet Explorer 8 and 9 do not support this option.
...	Ignored, included to require named arguments and for future feature expansion.
updateOn	A character vector specifying when the input should be updated. Options are "change" (default) and "blur". Use "change" to update the input immediately whenever the value changes. Use "blur"to delay the input update until the input loses focus (the user moves away from the input), or when Enter is pressed (or Cmd/Ctrl + Enter for textAreaInput()).

Value

A text input control that can be added to a UI definition.

Server value

A character string of the password input. The default value is "" unless value is provided.

    isolate(input$password)
  })
