html - shiny.fluent：在下拉列表中包含自定义 svg 图标

Question

有没有办法重现https://developer.microsoft.com/en-us/fluentui#/controls/web/icon中的示例，以便在 shiny.fluent R 包中使用自定义 svg 图标？

这是我的 R 脚本，但它不起作用：

library(shiny)
library(shiny.fluent)

jscode <- "
registerIcons({
  icons: {
    'csv': (
      <svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 96 96' fill='#FFF' stroke-miterlimit='10' stroke-width='2'>

我想出了一个解决方案，指的是 Keytips 的 shiny.fluent示例

library(shiny)
library(shiny.fluent)

jscode <- "
jsmodule['@fluentui/react'].registerIcons({
  icons: {
    'csv': (
      React.createElement('svg', { xmlns: 'http://www.w3.org/2000/svg', viewBox: '0 0 96 96', fill: '#FFF', 'stroke-miterlimit': '10', 'stroke-width': '2' },
      React.createElement('path', { stroke: '#000000', d: 'M67.1716,7H27c-1.1046,0-2,0.8954-2,2v78 c0,1.1046,0.8954,2,2,2h58c1.1046,0,2-0.8954,2-2V26.8284c0-0.5304-0.2107-1.0391-0.5858-1.4142L68.5858,7.5858 C68.2107,7.2107,67.702,7,67.1716,7z' }),

const iconClass = jsmodule['@fluentui/react'].mergeStyles({

ui <- fluidPage(
  tags$head(tags$script(HTML(jscode))),     
  tags$div(
    FontIcon(ariaLabel = "CSV logo", iconName = "csv", className = JS("iconClass"))
  )
)

server <- function(input, output, session) {
}

shinyApp(ui,server)

我们可以React.createElement用

React.createElement('img', { src: '<image path>.svg',
            alt: 'CSV logo' })
