I'm using shinyjs::runjs() to run the javascript, using observeEvent() when the HTML content, contained in a reactive(), changes. everything is unstructured and the elements simply stack up one below the. Now all I needed was a way to execute this from a shiny button press. It initializes an empty UI and an empty server, and runs an app using these.

I discovered that if you use history.go(0), this effectively reloads the page. For example, executing history.go(-1) has the effect of going back one page. This has the effect of moving across your browsers history. I searched a bit, and discovered the javascript method history.go.

It’s a fairly common problem, across all of web design, not just R/Shiny. If you dig around online you’ll notice that many people have brought this up on Stack Overflow, Github, and Google Groups.
