sendSweetAlert no html option anymore

[mayeromain]

I was wondering why the HTML = T option on the sendSweetAlert function has been remove? Is there a solution to use the same code as before to have some html text display in the sweet alert?
Also, is it possible not to close the alert when we click outside the popup?
Thanks

Hello,
This option is no longer available in sweetalert 2.0, I'll look to find an alternative solution.

I added argument closeOnClickOutside to prevent closing when clicking outside, please install package from Github :

shinyApp(
  ui = fluidPage(
    tags$h1("Click the button"),
    actionButton(
      inputId = "success",
      label = "Launch a success sweet alert"
    )
  ),
  server = function(input, output, session) {
    observeEvent(input$success, {
      sendSweetAlert(
        session = session,
        title = "Success !!",
        text = "All in order",
        type = "success", 
        closeOnClickOutside = FALSE
      )
    })
  }
)

Hello,

thank you very much for your update and thanks for the package it is very useful!

[pvictor]

With a little JavaScript, argument html is back !
Glad you find the package useful :)

Try :

library("shiny")
library("shinyWidgets")

shinyApp(
  ui = fluidPage(
    tags$h1("Click the button"),
    actionButton(
      inputId = "sw_html",
      label = "Sweet alert with HTML"
    )
  ),
  server = function(input, output, session) {
    observeEvent(input$sw_html, {
      sendSweetAlert(
        session = session,
        title = "Success !!",
        text = tags$span(
          "In", tags$b("bold"), "and", tags$em("italic"),
          tags$br(),
          "and",
          tags$br(),
          "line",
          tags$br(),
          "breaks"
        ), 
        html = TRUE,
        type = "success"
      )
    })
  }
)

have you installed the dev version of shinyWidgets?

library(devtools)
install_github("dreamRs/shinyWidgets")

the dev version is shinyWidgets_0.4.1.910. Try to remove it and re-install using the code I provided above.

Have you plan to do the same on the confirmSweetAlert function? I realy like the way it can be customized using HTML and the possibility to force a click from the user.

[pvictor]

Yes, it works in the latest version. I tried to go further by passing input/output, it seems to work but I don't know if it is very robust. Thanks for the improvement suggestion, it was cool to do.

If you want to try it :

library("shiny")
library("shinyWidgets")
library("ggplot2")

shinyApp(
  ui = fluidPage(
    tags$h1("Click the button"),
    actionButton(
      inputId = "sw_html",
      label = "Sweet alert with ggplot"
    ),
    tags$style(".swal-modal {width: 70%;}")
  ),
  server = function(input, output, session) {
    observeEvent(input$sw_html, {
      sendSweetAlert(
        session = session,
        title = "Yay an histogram!",
        text = tags$div(
          plotOutput(outputId = "plot"),
          sliderInput(
            inputId = "slider", label = "Number of bins",
            min = 20, max = 90, value = 60, width = "100%"
          )
        ),
        html = TRUE
      )
    })
    output$plot <- renderPlot({
      ggplot(diamonds, aes(carat)) +
        geom_histogram(bins = input$slider)
    })
  }
)

[mayeromain]

you rock! This is really a good package thanks for all your updates.

[mayeromain]

maybe it's a problem on my side but the htlm = T option on the confirmSweetAlert and the sendSweetAlert didn't seem to work anymore on version 0.4.1.950
Here is a minimal example:

library("shiny")
library("shinyWidgets")


ui <- fluidPage(
  actionButton(
    inputId = "go",
    label = "Launch confirmation dialog"
  )
)

server <- function(input, output, session) {
  
  observeEvent(input$go, {
    sendSweetAlert(
      session = session, type = "warning",
      title = "Is the HTML </br>Working or not?",html =  T
    )
  })
  
}

shinyApp(ui = ui, server = server)

}

[pvictor]

You have to use argument text to use HTML, and if yous use raw HTML, you'll have to escape it with HTML like this :

library("shiny")
library("shinyWidgets")


ui <- fluidPage(
  actionButton(
    inputId = "go",
    label = "Launch confirmation dialog"
  )
)

server <- function(input, output, session) {
  
  observeEvent(input$go, {
    sendSweetAlert(
      session = session, type = "warning", title = NULL,
      text = HTML("Is the HTML </br>Working or not?"), html =  TRUE
    )
  })
  
}

shinyApp(ui = ui, server = server)

Hi Victor!
I noticed that it does not work on shiny-server pro:

Warning: Error in sendSweetAlert: unused argument (html = FALSE)
Stack trace (innermost first):
    65: observeEventHandler [/srv/shiny-server/case_studies_app_V3.2/server.R#485]
     1: runApp

no matter if it is set to TRUE or FALSE

Removing sendSweetAlert from the observeEvent would solve the problem. But this is not what I want to do :)

[pvictor]

Hello David,
Yes I removed the arg on the last CRAN release, bad idea...
It's back in the dev version, try re-install the package from Github.
I'll try release to CRAN tomorrow.

I confirm the problem is fixed using:

devtools::install_github("dreamRs/shinyWidgets")

as well as paracetamol ^_^

Cheers
