extendShinyjs(), the functions parameter must always be provided.extendShinyjs(), the script path parameter now behaves like any other Shiny web resource, which means it cannot be loaded from the local file system. The path must be discoverable by the browser, so it either needs to be a public URL, inside a www folder, or available via addResourcePath().refresh() function (#205)asis parameter to reset() function, which works like it does in all other functions that support asis (#146)extendShinyjs() now works with any web URL or any resource path (#201)reset() didn’t work when a sliderInput was initialized with value=NULL (#207)V8 as a package dependency.This update was 2 years in the making because it required a lot of testing by users to ensure none of these features cause any regression bugs in real apps.

extendShinyjs() where it didn’t work when using a script and didn’t have V8 installed (#64)2016-03-23
returnName parameter to colourInput(), which lets you get an R colour name instead of HEX value as the return value (#62)2016-03-19
colourPicker() to open a gadget that lets you pick colours, or choose Colour Picker from the Addins menu to run it.2016-01-31
html() function: don’t attempt to change innerHTML if the element does not exist2016-01-16
BREAKING CHANGE: the text function has been renamed to html (#42)
shinyjs now works with the new modules feature of Shiny (#50)
Refactor how shinyjs R engine works: instead of using cool meta programming that minimizes code and sends each shinyjs function request straight to JS, add a thin layer or R code for each function. This allows us to check the arguments, run custom code for each function, it allows the documentation to show the arguments instead of them being ..., and it fixes a few edge cases of calling shinyjs functions, such as calling shinyjs using do.call() (#51)
Update vignette/readme to include FAQ
Change internally the name of shinyjs functions to make the JavaScript function names more unique to avoid potential conflicts with user-defined JS functions

hidden() now works when used on an element with a display CSS property2015-12-01
extendShinyjs() for users that cannot install the V8 package2015-09-15
html argument to useShinyjs(), which adds support for using shinyjs in shiny apps that are built with index.html instead of using Shiny UI (more details in the README)2015-09-13
debug parameter to useShinyjs that will cause detailed debugging messages to be printed to the JavaScript console when turned on2015-09-05
disabled now works with all input typesenable/disable did not work on selectInput, sliderInput, and actionButton
2015-09-05
onclick and onevent now work with dynamically generated elements. Not a trivial fix, but enough people requested it that it was important2015-09-04
Lots of big changes
delay function, which allows you to run code after a specified amount of time has elapseddelay parameter from hide/show/toggle because the same behaviour can now be achieved using the delay function (if you previously used show(id = "text", delay = 2), you can now use delay(2000, show("text")))onevent function, which is similar to onclick but can be used for many other different eventsreset now works with dynamically generated elements (inputs that are created with renderUI)disabled work for dynamically generated elementsresettable function2015-08-19
onclick documentation, to make it clear that it can’t work with dynamic UIs2015-08-12
shinyjs.init function when using extendShinyjs that runs when the page loads. This provides the user a way to register event handlers or do some initializations that automatically run on page load rather than calling it manually in the serverdisabled function that initializes a Shiny input in a disabled statermd parameter to useShinyjs that lets you use shinyjs inside interactive R markdown documents (default is FALSE to favour regular Shiny apps)2015-07-23
session parameter! A shiny server function defined as server = function(input, output) {...} can work with shinyjs

colourInput (feature request from Hadley and other Twitter users)2015-06-23
selector param to the disable/enable/toggleState functions and the addClass/removeClass/toggleClass functions so that multiple elements can be targeted in batchtransparentText param to colourInput
2015-06-22
colourInput that’s available via runExample and on my shiny server
colourInput
colourInput using a better library that I modified to work well with shiny inputsuseShinyjs() or extendShinyjs() will not result in duplicated HTML anymore. This can be useful if the UI is including a few external UI pieces and they independently make a call to useShinyjs().2015-06-17
colourInput that can be used as an input element to select colours, and its corresponding updateColourInput. This doesn’t really fit the shinyjs model of running JS functions, this feels like something very different from the rest of the functions in this package, it might move somewhere else in the future.2015-05-30
hidden can now accept multiple tags or a tagList or a list of tags (previously only a single tags was allowed)
allow hide/show/toggle to be run on any JQuery selector, not only on a single ID
2015-05-28
delay argument to hide/show/toggle so that you can now hide or show an element after a short delay instead of immediately. Useful for showing a message for a few seconds and then fading it away.2015-05-27
text argument to extendShinyjs so that JavaScript code can be provided as a string instead of in a separate file. Useful if your JS code is very short and simple and you don’t want to create a new file2015-05-25
add extendShinyjs function - allow users to add their own JavaScript functions that can be called as if they are regular R code
disable and enable now work for ALL shiny input types
show and hide now work for any HTML tag including all shiny input types
better onclick behaviour - when set on a shiny input, trigger the event when any part of the input is clicked
improve implementation of reset and simplify function call to it
2015-05-23
add reset function that allows input elements to be reset to their original values
add function runjs to run arbitrary javascript code (not recommended to use in published shiny apps)
relax R version requirement to 3.1.0
look for session object in all parent frames, so that shinyjs functions can work from helper functions and not only from within the main server function
refacor internal code
update example apps and vignette to include reset function and condition param in toggle functions
2015-04-24
add a condition argument to toggle/toggleState/toggleClass that allows you to pass a boolean condition to determine if to show/hide (enable/disable, etc) based on that condition. Useful to do things like toggleState(id = "submitBtn", condition = nchar(input$text) >= 3)
fix hidden so that if there are elements created dynamically using renderUI, shiny will render them when they are made visible
better implementation of toggle
using enable/disable/toggleState on a selectize input works
better implementation of toggleState
2015-04-18
bugfixes to onclick() (evaluate expressions in the correct environment)
rename alert() to info() because when the app was deployed in a Shiny Server (shinyapps.io or my own shiny server), it was printing the alret twice - probably because shiny server somehow intercepts the alert call too
rename innerHTML() to text() to make it more understandable for the average user
add add param to onclick()
add add param to text()
add inlineCSS() function to easily add inline CSS to a Shiny app
add documentation to all functions
add “demo” example app that provides a safe way to experiment with shinyjs by providing a predetermined set of functions to run
add “basic” example app that shows how some shinyjs functions can be used together in a real (very simply) Shiny app
add vignette and README, get ready for CRAN submission
2015-04-02
New function: onclick - allows the user to run an R expression (including shinyjs expressions) when a specific element in the Shiny app is clicked.
2015-04-02
The user is no longer required to set the shiny session or to pass it into any function calls. Every shinyjs function will try to dynamically figure out the correct Shiny session to use. The previous code with explicit sessions is still in the codebase but has been commented out so that it’ll be easy to switch back to it in the near future in case the new approach doesn’t always work.
This has been a pending change for a while but I was hesitant to use it because I still don’t fully understand the call stack and I’m not 100% sure this will always be correct. But it does make sense to me and it seems to work so I’ll give it a go.
