reset {shinyjs} | R Documentation

## 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)

### Arguments

`id` | The id of the input element to reset or the id of an HTML tag to reset all input elements inside it.

### Note

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