Reading javascript variable into shiny/R on app load

Question

What I want to do is get the user ID from a wordpress logged-in user when I load a shiny app in an iframe. This variable could then be used to save and modify user-specific

Answer 1

If you want to call onInputChange as soon as the Shiny app starts then you need to use the following JavaScript code instead of listening for click events.

$(function() {
  setTimeout(function() {
    Shiny.onInputChange("mydata", userID);
  }, 10)
});
