[英]Overriding CSS in Shiny progress bar
I am trying to understand why there is a gray background in my progress bar (created using timer.js). 我试图了解为什么进度条中有灰色背景(使用timer.js创建)。
I've tried changing the background-color, background-style to none or #FFFFFF, but the gray background is still there. 我尝试将background-color,background-style更改为none或#FFFFFF,但是灰色背景仍然存在。
server.R server.R
function(input, output, session) {
mylevels <- reactive({
Sys.sleep(100)
input$num_levels
})
output$out <- renderText({
return(paste0(mylevels()," is selected.."))
})
}
ui.R: ui.R:
library("shinythemes")
fluidPage(theme = shinytheme("spacelab"),
navbarPage("Test", id = "allResults",
tabPanel(value ='inputParam', title = 'User Actions',
sidebarLayout(
sidebarPanel(
# Show Timer
conditionalPanel("updateBusy() || $('html').hasClass('shiny-busy')",
id='progressIndicator',
"Calculation in progress ....\n",
div(class='progress',includeHTML("timer.js"))
),
tags$head(tags$style(type="text/css",
'#progressIndicator {',
' position: fixed; bottom: 15px; right: 15px; width: 225px; height: 70px;',
' padding: 8px; border: 0.5px dotted #CCC; border-radius: 8px; ',
'}'
)),
numericInput("num_levels", label = "", value = 3)
),
mainPanel(
textOutput('out')
)
)
)
))
<script type="text/javascript"> var wasBusy = false; var elapsedTimer = null; var startTime = null; function updateBusy() { var isBusy = $('html').hasClass('shiny-busy'); if (isBusy && !wasBusy) { startTime = new Date().getTime(); elapsedTimer = setInterval(function() { var millisElapsed = new Date().getTime() - startTime; $('.progress').text(Math.round(millisElapsed/1000) + ' seconds have elapsed'); }, 1000); } else if (!isBusy && wasBusy) { clearInterval(elapsedTimer); } wasBusy = isBusy; } </script>
将以下内容添加到ui.r
text/css
样式标签中:
.progress {background:#FFFFFF; box-shadow:none;}
