Don't generate random id

[jennybc]

I'm not sure if this is a listviewer problem or an htmlwidget problem.

I'm using listviewer in an R markdown website and every time I build the site, the listviewer widgets have a diff, even thought the data does not change. I made a commit consisting solely of this phenomenon as an example:

jennybc/purrr-tutorial@010cb57

Is there any way to suppress that?

This is not unique to listviewer, but there is an easy solution for all htmlwidgets that I failed to provide for listviewer. All htmlwidgets will get a pseudo-random id unless they specify the elementId in createWidget. I just added to jsonedit, and I will try to get up to CRAN by end of the week.

# devtools::install_github("timelyportfolio/listviewer")
library(listviewer)
jsonedit(list(), elementId="my-special-unique-id")

other htmlwidgets

For other htmlwidgets, proper usage and implementation of elementId varies by author and timing. However after creation, you can add an elementId for other htmlwidgets by assigning an elementId after construction. Assuming I did not add the elementId argument to jsonedit, here is how we could achieve this.

# see above for better usage but here is a way to provide elementId
#    if a htmlwidget does not provide a elementId argument in the constructor function

library(listviewer)

je <- jsonedit(list())
je$elementId <- "my-special-override-id"
je

I was also thinking maybe I could cache that chunk? Obviously I should just try that and see what happens. But I will look forward to using elementId. Thanks!

Sure, thanks for using and reporting! I also added react-json as another list viewer. It is a much sparser react-based viewer. There are a couple other really nice react-based json inspectors that I also plan to add soon.

Hopefully, I can submit this to CRAN by end of day.

Hopefully, I can submit this to CRAN by end of day.

Is there anyway a solution for this makes it in? #18

I am using elementId as intended now. Does just what I hoped. Thanks.

Great, thanks for the reminder. I was in such a rush last year with the widgets that I was not able to implement my checklist on all of them. Really glad you are using listviewer.
