问题描述

这是数据框

sports=data_frame(question=c("<h5>This gives you more @R_608_4045@ion about pro Football
                             What position would you prefer to play in pro Football?</h5>","</h5>This gives you more @R_608_4045@ion about pro Soccer
                             What position would you prefer to play in pro Soccer?</h5>","</h5>This gives you more @R_608_4045@ion about pro Hockey
                             What position would you prefer to play in pro Hockey?</h5>"),`Expected Money`= c(list(c('First Year = 10','First 3 Years= 50')),list(c('First Year = 15','First 4 Years= 50')),NA),`Expected Injury Risk`= c(list(c('Death=0.0001%','Severe= 0.001%')),list(c('Minor=0.01%','Severe= 0.0001%')),list(c('Death=0.00001%','Severe= 0.002%'))),`Field Dimentions`=c( NA,list(c('length=100','width=60')),list(c('length=50','width=30'))),position=c(list(c('QB',"DB","RB","LB")),list(c('Forward','Defender','Goal keeper')),'Winger','Goal Tender')))
)

我要使其如下图所示。我希望不显示带有choices = NA的下拉按钮。每行底部的按钮仅供参考，对于这些响应我不感兴趣。我只会对问题的回答感兴趣，即为哪一行选择了哪个职位。感谢您的帮助！

To be Displayed DT

以下代码无法按我的需要排列信息按钮。仅显示第一个信息按钮。

library(shiny)
library(DT)
library(shinyWidgets)


shinyApp(
  ui <- fluidPage(
    DT::dataTableOutput("data"),textoutput('myText')
  ),server <- function(input,output) {
    
    myValue <- reactiveValues(result = '')
    
    shinyInput <- function(FUN,len,id,...) {
      inputs <- character(len)
      for (i in seq_len(len)) {
        inputs[i] <- as.character(FUN(paste0(id,i),...))
      }
      inputs
    }
    L=NULL
 
    df <- reactiveValues(data = data.frame(
      
      Name = paste('<h5>',c('Dilbert is a dragon with high speed in the air','Alice','Wally','Ashok','Dogbert'),'</h5>',#cbind instead of paste arranges buttons row-wise
       
       cbind(shinyInput(pickerInput,5,'button_',label = "Pets",choices=1:3 ),shinyInput(pickerInput,len=5,id='Friends',label='Friends',choices=LETTERS[1:3] )
                      )),Res= shinyInput(dropdown,id='Enemies',label = "Enemies")
                  ))
    
    
    output$data <- DT::renderDataTable(
      df$data,server = FALSE,escape = FALSE,selection = 'none'
    )
    
    observeEvent(input$select_button,{
      selectedRow <- as.numeric(strsplit(input$select_button,"_")[[1]][2])
      myValue$result <<- paste('click on ',df$data[selectedRow,1])
    })
    
    
    output$myText <- renderText({
      
      myValue$result
      
    })

  }
)
