I am open to any method that will simulate "clicking and expanding" the below dropdown when a search is entered.
#Shiny shinyjs runjs code
However, the code provided in the latter example is so minimal that I can't seem to replicate it. click method, and have tried using the selectize API method described here. However, I am struggling to write the JS code needed to expand the dropdown.
#Shiny shinyjs runjs how to
I was able to use this topic to figure out how to reference the dropdown from JavaScript. When a user types something into the search bar and clicks the search icon / presses enter, I want the choices in the below dropdown to be shown (similar to if I had clicked on the selectizeInput), so it's clear to the user that their search was processed.
#Shiny shinyjs runjs download
in the second run when the button is built, then it is working fine and downloading the file without user clicking the download button.In my app, I have a search bar, which filters the options in a related selectizeInput.
Write.xlsx2(df, con, sheetName="example", append=TRUE)īut it is not entering the output$downloadData <- downloadHandler loopįor the first time. Usecase: I am building an excel file using downloadhandler and I want to download the file without clicking the downloadbutton so I am using runjs function from shinyjs package. I am trying to use runjs with renderUI, then it is not working for the first time.Ĭould you please suggest me how can I proceed with it? Thank you for the making such a wonderful package, It's a bit weird I admit, I hope shiny has a better way to do it, but off the top of my head this should work: wrap all the observe() statements inside a function, say function foo(). I'm not sure what the best way to know when a UI is finished rendering (I wonder if Shiny has a nice way to do that or not), but for this example, since you're rendering a button and the initial value is 0, we could use that to know when the UI renders. If you are rendering elements dynamically and you want to have an associated onclick event, the onclick needs to register after the element is created. But you're making that call before the element exists, so there is nothing to do. The reason onclick isn't working also makes sense: when making the call to onclick(.), the javascript immediately registers a click on that element. Any input that is created dynamically using uiOutput + renderUI will not be resettable. Note that this function only works on input widgets that are rendered in the UI. For the reset function, the documentation says: This is not a shinydashboard issue, the same is true if you're in a normal shiny app. Shinyjs ::toggleClass( "myapp ", "big ", input $ big)Įverything is working if I don't use the uiOutput() function and put the code inside the ui. Shinyjs ::onclick( "update ", shinyjs ::text( "time ", date())) Shinyjs ::toggle( id = "advanced ", anim = TRUE)) Shinyjs ::toggleState( "submit ", !is.null( input $ name) & input $ name != " ") big = "font-size: 2em ")),ĬheckboxInput( "big ", "Bigger text ", FALSE),Ī( id = "toggleAdvanced ", "Show/hide advanced info ", href = "# "),Ī( id = "update ", "Update ", href = "# ")
