onevent
(Package: shinyjs) :
Run R code when an event is triggered on an element
onclick runs an R expression (either a shinyjs function or any other code) when an element is clicked.
onevent is similar, but can be used when any event is triggered on the element, not only a mouse click. See below for a list of possible event types. Using "click" results in the same behaviour as calling onclick.

extendShinyjs
(Package: shinyjs) :
Extend shinyjs by calling your own JavaScript functions
Add your own JavaScript functions that can be called from R as if they were regular R functions. This is a more advanced technique and can only be used if you know JavaScript. See 'Basic Usage' below for more information or view the full README and demos to learn more. Note that you have to install the 'V8' package in order to use this function.

Display or hide an HTML element.
show makes an element visible, hide makes an element invisible, toggle displays the element if it it hidden and hides it if it is visible.
If condition is given to toggle, that condition will be used to determine if to show or hide the element. The element will be shown if the condition evaluates to TRUE and hidden otherwise. If you find yourself writing code such as if (test()) show(id) else hide(id) then you can use toggle instead: toggle(id = id, condition = test()).
