reset {shinyjs}

Reset input elements to their original values

Description

Reset any input element back to its original value. You can either reset one specific input at a time by providing the id of a shiny input, or reset all inputs within an HTML tag by providing the id of an HTML tag.

Reset can be performed on any traditional Shiny input widget, which includes: textInput, numericInput, sliderInput, selectInput, selectizeInput, radioButtons, dateInput, dateRangeInput, checkboxInput, checkboxGroupInput, colourInput, passwordInput, textAreaInput. Note that actionButton is not supported, meaning that you cannot reset the value of a button back to 0.

Usage

reset(id = "", asis = FALSE)

Arguments

id

The id of the input element to reset or the id of an HTML tag to reset all inputs inside it. If no id is provided, then all inputs on the page are reset.

asis

If TRUE, use the ID as-is even when inside a module (instead of adding the namespace prefix to the ID).

Note

shinyjs must be initialized with a call to useShinyjs() in the app's ui.
