问题描述

在选项卡之间创建链接的解决方案在这里选项卡之间的R闪亮的生成链接确实不错，但不适用于DT包(对我来说).有人可以告诉我，与没有DT软件包的解决方案相比，使用DT库的示例代码在做什么?

Solution for creating links between tabs a have found here R shiny build links between tabs is really nice, but it's not working with DT package (for me..).Can anybody tell me, what am I doing wrong in my example code using DT library in compare to the solution without DT package?

library(shiny)
library(DT)

server <- function(input, output) {
    output$iris_type <- DT::renderDataTable({
        datatable(data.frame(Species=paste0("<a href='#filtered_data'>", unique(iris$Species), "</a>")),
                  escape = FALSE,
                  options = list(initComplete = JS(
'function(table) {
    table.on("click.dt", "tr", function() {
    Shiny.onInputChange("rows", table.row( this ).index());
    tabs = $(".tabbable .nav.nav-tabs li a");
    $(tabs[1]).click();
    });
}')))
    })

  output$filtered_data <- DT::renderDataTable({
      if(is.null(input$rows)){
          iris
      }else{
          iris[iris$Species %in% unique(iris$Species)[as.integer(input$rows)+1], ]
      }
      })
  }

ui <- shinyUI(fluidPage(
    mainPanel(
        tabsetPanel(
            tabPanel("Iris Type", DT::dataTableOutput("iris_type")),
            tabPanel("Filtered Data", DT::dataTableOutput("filtered_data"))
        )
    )
))

shinyApp(ui = ui, server = server)

推荐答案

您可以尝试下面的代码.我更改了将选项卡切换到回调(具有表格作为参数)的功能，并在您的output$filtered_data中，将iris替换为datable(iris)，因为您正在使用DT::renderDataTable

You could try the code below. I changed the function switching the tabs to the callback (which has table as an argument) and in your output$filtered_data, replaced iris by datable(iris) since you are rendering with DT::renderDataTable

library(shiny)
library(DT)

server <- function(input, output) {
  output$iris_type <- DT::renderDataTable({
    datatable(data.frame(Species=paste0("<a href='#filtered_data'>", unique(iris$Species), "</a>")),
              escape = FALSE,
              callback = JS(
                'table.on("click.dt", "tr", function() {
    tabs = $(".tabbable .nav.nav-tabs li a");
    $(tabs[1]).click();})'))
  })

  output$filtered_data <- DT::renderDataTable({
    selected <- input$iris_type_rows_selected
    if(is.null(selected)){
      datatable(iris)
    } else {
      datatable(iris[iris$Species %in% unique(iris$Species)[selected], ])
    }
  })
}

ui <- shinyUI(fluidPage(
  mainPanel(
    tabsetPanel(
      tabPanel("Iris Type", DT::dataTableOutput("iris_type")),
      tabPanel("Filtered Data", DT::dataTableOutput("filtered_data"))
    )
  )
))

shinyApp(ui = ui, server = server)

请注意，这需要 DT > = 0.0.62 .

Please note this requires DT >= 0.0.62.
