R Shiny:shinyBS将navbarPage与bsModal一起使用 [英] R Shiny: Use navbarPage with bsModal by shinyBS

问题描述

我正在尝试在navbarPage中添加一个tabPanel，以便当您单击它时打开一个模式窗口，而不是一个新的选项卡.以下代码段无效，因为tabPanel没有id参数.

I'm trying to add a tabPanel in navbarPage so that when you click on it opens a modal window instead of a new tab. The snippet below is not valid because tabPanel does not have an id parameter.

library(shiny)
library(shinyBS)
shinyUI(fluidPage(
    navbarPage("Sample App", id = "main_menu", 
        tabPanel("Open Modal", id = "moda")),
    bsModal("modal1", "Example", "moda", p("This is a modal"))
)

如果我通过浏览器编辑生成的HTML代码，则可以通过更改以下行来实现

If I edit the generated HTML code from browser, I can make this possible by changing the line

<a href="#tab-9741-5" data-toggle="tab" data-value="Open Modal">Open Modal</a>

与

<a href="#" data-toggle="modal" data-target="#modal1">Open Modal</a>

在<li>元素上.

任何想法如何做到这一点，或者至少如何覆盖闪亮的生成的html?

Any idea how to do this or at least how can I override the generated html from shiny?

推荐答案

一种解决方案是使用Javascript重写选项卡标题的属性.下面的JS代码找到标签标题链接，并重写其属性.

One solution is to use Javascript to rewrite the attribute for the tab title. The JS code below finds the tab title link, and rewrites its attributes.

library(shiny)

jsStr <- '$(document).ready(function(){
  $("a[data-value=\'OpenModal\']").attr({
    "href":"#", 
    "data-toggle":"modal",
    "data-target":"#modal1"
  });
})
' 

ui <- shinyUI(fluidPage(
  tags$head(tags$script(HTML(jsStr))),
  navbarPage("title",
    tabPanel("OpenModal")
  ),
  bsModal("modal1", "Example", "moda", p("This is a modal"))
))
