shinyBS 警报中的 Mathjax
Mathjax in a shinyBS alert
有没有办法在 shinyBS
创建的警报中使用 MathJax?下面的尝试没有按预期工作。
library(shiny)
library(shinyBS)
shinyApp(
ui =
fluidPage(
sidebarLayout(
sidebarPanel(textInput("num1", NULL, value = 100),
"divided by", textInput("num2", NULL, value = 20),
"equals", textOutput("exampleOutput")),
mainPanel(
withMathJax(bsAlert("alert"))
)
)
),
server =
function(input, output, session) {
output$exampleOutput <- renderText({
num1 <- as.numeric(input$num1)
num2 <- as.numeric(input$num2)
if(num2 == 0) {
createAlert(session, "alert", "exampleAlert", title = "Oops",
content = HTML("You cannot divide by <span class='math inline'>\(0\)</span>."))
} else {
closeAlert(session, "exampleAlert")
return(num1/num2)
}
})
}
)
这与 OP 和
中的 withMathJax(bsAlert("alert"))
一起使用
content = "You cannot divide by <span class='math inline'>\(0\)</span>.<script>if (window.MathJax) MathJax.Hub.Queue(['Typeset', MathJax.Hub]);</script>"
奇怪,因为脚本被包含了两次。
