I'm using shiny library(shinyscreenshot). I have a datatable within a tabBox and would like the user to be able to download a screenshot of the datatable with a specific div id that changes based on the pickerInput. I've noticed, after I select choices in the pickerInput, the new datatable rendered has a different div id. The different div's for the datatables are as follows: #DataTables_Table_0, #DataTables_Table_1, #DataTables_Table_2, #DataTables_Table_3, etc.
Is there a way I can still use "screenshotButton()" and be able to update the selector to be whatever selector matches the string?
I ran into this issue when I used the following code and nothing downloaded after the first download:
screenshotButton(filename = "TEST.png",label = "Download",download = TRUE, scale =3, selector = "#DataTables_Table_0")
I thought about using an attribute selector similar to:
[attribute~="value"]
where my code would look something like this to capture a specific string match within the selector but no luck.
screenshotButton(filename = "TEST.png",label = "Download",download = TRUE, scale =3, [id~="DataTables_Table_"])
Also, I used the id = "#table" which produces a valid download but I would like to stick with the #DataTables_Table id as this would allow for a png which shows the datatable in the most compact, cropped format without any extra filters or tabs showing within the screenshot.
Thank you in advance.
You were very close! you can use the *= operator to aim for attribute that begins with selector:
selector = "[id*='DataTables_Table_']"
