如何通过单击按钮翻转闪亮的形状? [英] How to flip up shapes in shiny by clicking a button?

问题描述

我想在我闪亮的应用程序中包含一个语义形状元素(形状:https://semantic-ui.com/modules/shape.html#/usage).我可以使用 shinyjs 和 shiny.semantic 构建形状.但是我不知道如何创建一个通过点击来翻转形状的按钮.

I want to include a semantic shape element in my shiny app (shapes: https://semantic-ui.com/modules/shape.html#/usage). I am able to construct the shape by using shinyjs and shiny.semantic. But I don't know how to create a button that flips the shape by clicking on it.

这里有一个例子:

UI.R:

    library(shiny)

    # Define UI for application that draws a histogram
    shinyUI(semanticPage(
      shinyjs::useShinyjs(),

      div(class="ui text shape",
          div(class="sides",
              div(class="ui header side active","This side starts visible."),
              div(class="ui header side","This is yet another side"),
              div(class="ui header side","This is the last side")
          )
      ),
 tags$button(id="test",class="ui button","Flip")

      ))

Server.R:

library(shiny)
library(shinyjs)
#devtools::install_github("Appsilon/shiny.semantic")
library(shiny.semantic)
#devtools::install_github("Appsilon/highlighter")
library(highlighter)
jsCode <- "
$('.shape').shape();
$('.shape').shape('flip up');
$('test').shape('flip up');
"

# Define server logic required to draw a histogram
shinyServer(function(input, output) {
  runjs(jsCode)

})

这会创建按钮和形状，但如何让按钮翻转形状?

This creates both the button and a shape, but how do I make the button flipping the shape?

推荐答案

我认为你需要这个 JS 代码:

I think you need this JS code:

jsCode <- "
$('.shape').shape();
$('#test').on('click', function(){$('.shape').shape('flip up');});
"

或者只是:

jsCode <- "
    $('.shape').shape();
    "

在用户界面中:

  tags$button(id="test", class="ui button", "Flip", onclick="$('.shape').shape('flip up');")
