Is there any way to add custom R-function action to a button in DT?
1
I'm trying to add a custom button performing the action defined by R-function to my datatable. I've used the same list of options in my R code as in Javascript code in Datatables manual, but it doesn't work.
Here is a code from Datatables manual:
$(document).ready(function() {
$('#example').DataTable( {
dom: 'Bfrtip',
buttons: [
{
text: 'My button',
action: function ( e, dt, node, config ) {
alert( 'Button activated' );
}
}
]
} );
} );
And here is my code in R:
require(DT)
DT::datatable(iris,
extensions = 'Buttons',
options = list(
dom = 'Bfrtip',
buttons = list(
list(
text = 'test',
action = print('1')
)
)
)
)
Executing it I've received an error:
Error in if (extend != "collection") extend else listButtons(cfg) :
argument is of length zero
r datatables dt

You have to set extend = "collection", like this:
library(DT)
datatable(iris,
extensions = 'Buttons',
options = list(
dom = 'Bfrtip',
buttons = list(
"copy",
list(
extend = "collection",
text = 'test',
action = DT::JS("function ( e, dt, node, config ) {
alert( 'Button activated' );
}")
)
)
)
)
But the action can only execute some Javascript, not a R command. However you can execute a R command by clicking a custom button if you put the datatable in a shiny application. Something like that:
library(shiny)
library(DT)
ui <- basicPage(
DTOutput("dtable")
)
server <- function(input, output, session){
output$dtable <- renderDT(
datatable(iris,
extensions = 'Buttons',
options = list(
dom = 'Bfrtip',
buttons = list(
"copy",
list(
extend = "collection",
text = 'test',
action = DT::JS("function ( e, dt, node, config ) {
Shiny.setInputValue('test', true);
}")
)
)
)
)
)
observeEvent(input$test, {
if(input$test){
print("hello")
}
})
}

That works, but I’ve changed your code slightly in order to use the button as a trigger. So I’ve addedpriority: "event"option as it was described in the section 'Values vs. Events' of this Shiny manual page.

Could you clarify why did you useif(input$test)? The code works fine for me without it.

@asvx You're right, theifis useless. And you're right to usepriority: "event". I didn't knowpriority: "event", I used a trick before to trigger the input change when the value does not change, but usingpriority: "event"is definitely better. Thanks.
