我有一个闪亮的应用程序与导航栏,我想让这个导航栏粘性。我检查了this page,在那里解释了这一点,我试图把CSS和JS代码放在shiny中,但没有成功(要看到这一点,运行应用程序,在表中选择50或100个观察结果,然后向下滚动)。
library(shiny)
library(dplyr)
ui <- navbarPage(
tags$head(
tags$style(HTML("
#navbar {
overflow: hidden;
background-color: #333;
}
/* Navbar links */
#navbar a {
float: left;
display: block;
color: #f2f2f2;
text-align: center;
padding: 14px;
text-decoration: none;
}
/* Page content */
.content {
padding: 16px;
}
/* The sticky class is added to the navbar with JS when it reaches its scroll position */
.sticky {
position: fixed;
top: 0;
width: 100%;
}
/* Add some top padding to the page content to prevent sudden quick movement (as the navigation bar gets a new position at the top of the page (position:fixed and top:0) */
.sticky + .content {
padding-top: 60px;
}
")),
tags$script(
"// When the user scrolls the page, execute myFunction
window.onscroll = function() {myFunction()};
// Get the navbar
var navbar = document.getElementById('navbar');
// Get the offset position of the navbar
var sticky = navbar.offsetTop;
// Add the sticky class to the navbar when you reach its scroll position. Remove 'sticky' when you leave the scroll position
function myFunction() {
if (window.pageYOffset >= sticky) {
navbar.classList.add('sticky')
} else {
navbar.classList.remove('sticky');
}
}"
)
),
tabPanel(
title = "test tab",
dataTableOutput("test_table")
),
selected = "test tab"
)
server <- function(input, output, session) {
output$test_table <- renderDataTable({
mtcars %>%
bind_rows(mtcars)
})
}
shinyApp(ui, server)
有没有可能让导航条粘起来?

按热度按时间nxowjjhe1#
您可以在
navbarPage
中使用position = c("fixed-top")
。这是你的问题。
