How to? Infinite scroll in DataTables for shiny 10.2 and above

[Willi Fiebranz]

Hi,

due to the latest update of the dataTable option parameters, I do not manage to regain the power of infinite scrolling dataTable content.

The "bScrollInfinite" does not work anymore, but the "dom" alternative via using the Scroller plugin does not seem to take any desired effect.

Does someone have a similar problem or has someone found a solution with a working code example (from R/shiny, NOT in general  for DataTables)?

Regards...

According to http://legacy.datatables.net/ref, this option has been
deprecated, and replaced by sScrollY later. Then DataTables 1.10.x
replaced it by scrollY: https://datatables.net/upgrade/1.10-convert
Then what you should really look at is:
http://datatables.net/reference/option/scrollY

Here is a minimal example:

library(shiny)
shinyApp(
ui = fluidPage(fluidRow(dataTableOutput('foo'))),
server = function(input, output) {
output$foo = renderDataTable({
iris
}, options = list(
scrollY = '300px', paging = FALSE
))
}
)

Hello, thanks for your reply.

While your example scrolls the whole table, it is not what I am looking for. You loaded the whole table on one page, which could become troublesome when you use very large tables.

What I was looking for is and working implementation of this new DataTable syntax in shiny: https://datatables.net/extensions/scroller/

It seems pretty cool...

I have implemented the scroller in the DT package, and you can find
examples here: http://rstudio.github.io/DT/extensions.html#scroller
