reset {shinyjs} | R Documentation |
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.
