Reset tableoutput with action button in shinydashboard - r

Question

I have an shinydashboard app, the app get an filter box and a tabset which show a datatatable depending on filter.
I have a reset button which reset the filters whith shinyjs::reset function, and I want to reset also the tableset and showing the complete table or nothing.
I want also to do it for a valuboxes.
My app is like this :
For server interface I have an basic : output$tableprint_A <- DT::renderDataRable ({})
ui :
body <- dashboardBody(
tabItems(
#### First tab item #####
tabItem(tabName = "fpc",
fluidRow(
infoBoxOutput("kpm_inf", width = 6),
infoBoxOutput(outputId = "fpc_inf", width = 6)
),
fluidRow(
box(title = "Variables filter",
shinyjs::useShinyjs(),
id = "side_panel",
br(),
background = "light-blue",
solidHeader = TRUE,
width = 2,
selectInput("aaa", "aaa", multiple = T, choices = c("All", as.character(unique(fpc$aaa))))
br(),
br(),
p(class = "text-center", div(style = "display:inline-block", actionButton("go_button", "Search",
icon = icon("arrow-circle-o-right"))),
div(style = "display:inline-block", actionButton("reset_button", "Reset",
icon = icon("repeat")))),
p(class = 'text-center', downloadButton('dl_fpc', 'Download Data'))),
tabBox(
title = tagList(),
id = "tabset1",
width = 10,
tabPanel(
"A \u2030 ",
DT::dataTableOutput("tableprint_A"),
bsModal(id = 'startupModal', title = 'Update message', trigger = '',
size = 'large',
tags$p(tags$h2("Last update of A : 01/09/2017",
br(), br(),
"Last update of B : 01/09/2017",
br(), br(),
"Last update of C : 01/09/2017",
style = "color:green", align = "center")))
),
tabPanel(
"B % Table",
DT::dataTableOutput("tableprint_B")),
type = "pills"
)
),
fluidRow(
# Dynamic valueBoxes
valueBoxOutput("info_gen", width = 6)
)
I tried this :
observeEvent(input$reset_button, {
output$tableprint_A <- NULL
})
Edit:
I want something like that, but when I action the search button I want it to appear again :
shinyjs::onclick("reset_button",
shinyjs::toggle(id = "tableprint_A", anim = TRUE))

You should try this out:
output$tableprint_A <- renderDataTable({
if(input$reset_button == 1) {
NULL
}else{
datatable(...)
}
})
if the button is clicked then nothing will be displayed, else the datatable is shown.
[EDIT]
library(shiny)
library(DT)
shinyApp(
ui = fluidPage(selectInput("select", "select", choices = unique(iris$Species), multiple = T),
actionButton("go_button", "Search",
icon = icon("arrow-circle-o-right")),
actionButton("reset_button", "Reset",
icon = icon("repeat")),
DT::dataTableOutput('tbl')),
server = function(input, output) {
values <- reactiveValues(matrix = NULL)
observe({
if (input$go_button == 0)
return()
values$matrix <- iris[iris$Species %in% input$select, ]
})
observe({
if (input$reset_button == 0)
return()
values$matrix <- NULL
})
output$tbl = DT::renderDataTable({
datatable(values$matrix, options = list(lengthChange = FALSE))}
)
}
)
