在闪亮的仪表板中为滑块添加不同的静态颜色

Question

我很有光泽.我想为滑动条提供静态颜色,而不管在闪亮的仪表板中选择的范围.我希望滑块有不同的颜色如下,例如:0到40 - 红色,40到60 - 蓝色,60到100 - 绿色.请帮我解决这个问题.我的代码,

library(shiny)
library(shinydashboard)

ui <- dashboardPage(skin = "black",
                    dashboardHeader(title = "test"),

                  dashboardSidebar(
                    sidebarMenu(
                      menuItem("Complete", tabName = "comp"))),

                    dashboardBody(
                      tabItems(
                        tabItem(tabName = "comp",
                          fluidRow(
                              sliderInput("range_var", "", value = c(90,100), min = 0, max = 100, width = '200%'))))))

server <- function(input, output, session) { 
  observe({
    updateSliderInput(session, "range_var", label = "", value = c(90, 100), min = 0, max = 100)
  })
}
shinyApp(ui, server)

谢谢Balaji

哦，那我误解了你的问题。您也可以通过使用 css 命令和正确的选择器来实现此目的：

library(shiny)
library(shinydashboard)
library(shinyjs)

ui <- dashboardPage(skin = "black",
                    dashboardHeader(title = "test"),
                    dashboardSidebar(
                      sidebarMenu(
                        menuItem("Complete", tabName = "comp"))),
                    dashboardBody(
                      inlineCSS(".irs-line-left { background-color: red; width: 40%;}
                                 .irs-line-mid { background-color: blue; width: 20%; left: 40%;}
                                 .irs-line-right { background-color: green; width: 40%; left: 60%;}
                                "
                                ),

                      shinyjs::useShinyjs(),
                      tabItems(
                        tabItem(tabName = "comp",
                                fluidRow(
                                  sliderInput("range_var", "", value = c(90,100), min = 0, max = 100, width = '200%'))))))

server <- function(input, output, session) { 
}

shinyApp(ui, server)
