当我在社交媒体上共享我的Shinyapp时,代码显示在标题图像下,看起来不太好。如何控制我的Shinyapp的社交共享图像和文本?我已经使用Shinyapps.io部署了该应用程序。
请参见下图作为示例:
链接到应用:https://regionalinnovationdatalab.shinyapps.io/Dashboard/
链接到可在其中找到应用程序代码和数据的Gitlab:https://gitlab.com/r.chappell/2019_ElectionApp_RIDL
插入标题图像的UI代码:
ui <- shiny::fluidPage( #use fluid page so that the app adjusts to the user's screen size and device
titlePanel(div(img(src='DATA DASHBOARD V3.png', height = 80))), #header title with image as the whole header ( must save header image in a subfolder titled 'www')
tags$head(tags$style(
type="text/css",
"img {max-width: 100%; width: 100%; height: auto}" #makes image size responsive to device and screen
)),
theme = "journal", #selected theme from shinythemes package
title=" RIDL: 2019 Election App", #title of web brower tab
br(),
答案 0 :(得分:0)
在寻求R Studio支持的帮助后,他们说将Java脚本代码发布到Shinyapps.io时出现问题,这就是为什么它不起作用的原因。
我最终找到了解决方法。
我更改了此代码:
ui <- shiny::fluidPage( #use fluid page so that the app adjusts to the user's screen size and device
titlePanel(div(img(src='DATA DASHBOARD V3.png', height = 80))), #header title with image as the whole header ( must save header image in a subfolder titled 'www')
tags$head(tags$style(
type="text/css",
"img {max-width: 100%; width: 100%; height: auto}" #makes image size responsive to device and screen
)),
对此:
ui<-shiny::fluidPage(
titlePanel(div(img(src='DATA_DASHBOARD_V3.png', height = "auto", width = "100%")))),
此代码删除了以前出现的Java脚本代码,但与Facebook共享时不包含缩略图。 R Studio说他们正在解决这个问题,但这是目前的解决方案。
