我正在使用Shiny与Shiny Semantic库来使应用程序看起来不错。使用showModal(modalDialog())的标准Shiny弹出消息不能与Semantic UI一起使用,所以我使用了shinyjs来使用一些javascript来允许模态。使用全局定义的js模式,如何将数据表集成到模态中?这是一个最小的例子:
library(shiny)
library(shinyjs)
library(shiny.semantic)
library(DT)
modal.js = "$('.ui.modal')
.modal('show')
;"
server <- function(input, output, session) {
output$my_table = DT::renderDataTable({
head(iris)
})
observeEvent(input$open_modal, {
runjs(modal.js)
})
}
ui <- semanticPage(
suppressDependencies("bootstrap"),
useShinyjs(),
div(class = "ui modal",
div(class="header", 'Modal header'),
p('Placing DT::dataTableOutput("my_table") here fails.
If it was displayed, I would select a row and return the value to a reactiveValue.')
),
div(class = "ui basic button action-button", id = "open_modal", "Open modal ui"),
div(class = "ui raised segment", DT::dataTableOutput("my_table"))
)
shinyApp(ui, server, options = list(launch.browser = TRUE))

我今天遇到了同样的问题,并设法找到一种解决方法。当模式在shiny.semantic
中打开时,数据表输出仍被分类为不可见。要解决此问题,您只需在JavaScript中添加额外的一行:
$('#my_table').show().trigger('shown');
如果要在关闭时再次将其隐藏,则需要添加更多JS,但是在UI中使用tags$script()
而不是在服务器中可能更好。
更新的应用程序:
library(shiny)
library(shinyjs)
library(shiny.semantic)
library(DT)
modal.js <- "$('.ui.modal').modal('show');
$('#my_table').show().trigger('shown');"
server <- function(input, output, session) {
output$my_table = DT::renderDataTable(head(iris))
observeEvent(input$open_modal, runjs(modal.js))
}
ui <- semanticPage(
suppressDependencies("bootstrap"),
useShinyjs(),
div(
class = "ui modal",
div(class = "header", "Modal header"),
div(class = "content", div(class = "ui raised segment", DT::dataTableOutput("my_table")))
),
div(class = "ui basic button action-button", id = "open_modal", "Open modal ui")
)
shinyApp(ui, server, options = list(launch.browser = TRUE))

放入dataTableOutput
output$my_table = DT::renderDataTable({
datatable(head(iris), class = "compact", escape = FALSE) })
