In shinyjs: Easily Improve the User Experience of Your Shiny Apps in Seconds

shinyjs 2.1.0 (2021-12-20)

• New feature: you can now reset all inputs on the page by calling reset() with no arguments (#222)
• New feature: Add a removeEvent() function which removes events added to HTML elements with onclick() or onevent() (#244)
• Fix bug: disable() did not work on nested download buttons (#223)
• Fix bug: Don't automatically namespace ID arguments in custom extendShinyjs functions (#229)
• Fix bug: ensure that extendShinyjs() functions don't overwrite native {shinyjs} functions (#230)

shinyjs 2.0.0 (2020-08-24)

• IMPORTANT CHANGE Remove commercial license (it only existed because some big companies asked for it, but it ended up being a bigger headache for 99% of the community)
• BREAKING CHANGE When using extendShinyjs(), the functions parameter must always be provided.
• BREAKING CHANGE When using 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().
• New feature: add a refresh() function (#205)
• New feature: add asis parameter to reset() function, which works like it does in all other functions that support asis (#146)
• Fix bug: extendShinyjs() now works with any web URL or any resource path (#201)
• Fix bug: reset() didn't work when a sliderInput was initialized with value=NULL (#207)
• Remove V8 as a package dependency.

shinyjs 1.1 (2020-01-12)

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.

• BREAKING CHANGE The includeShinyjs parameter in runcodeUI() is now deprecated
• Fix bug: shinyjs functions used inside a module with a selector argument instead of an id argument didn't work (#175)
• Fix bug: shinyjs functions did not work with IDs that had a space in them (#176)
• Fix bug: non-selectize select inputs could not be disabled (#186)
• Fix bug: click() now works with download buttons (#198)
• New feature: added asis parameter to any function that takes an ID. When asis=TRUE, the ID will not be namespaced when inside a module (#118)
• New feature: added id parameter to runcode(), allowing it to work inside Shiny modules (#184)
• New feature: onevent() returns the offsetX and offsetY event properties
• New feature: onevent() accepts a properties parameter that allows the user to retrieve additional properties that are not whitelisted by default (#159)
• New feature: hide()/show() now only bubble up the DOM tree to the nearest input container if the current element is an input (#153)
• Documentation: added documentation about useShinyjs() side effects and about including shinyjs in packages (#182)

shinyjs 1.0 (2018-01-08)

• BREAKING CHANGE shiny version 1.0.0 is now required
• BREAKING CHANGE All colourInput-related functions are now defunct because they are now in the colourpicker package
• Added click() function that simulates a user clicking on a button
• Bug fix: reset() wasn't working on checkboxes/select inputs that had a comma in the value (#130)
• Bug fix: using disabled() on certain non-standard inputs (such as shinyFiles) had strange behaviour (#120)
• Bug fix: logjs()+showLog() wasn't working when app first runs
• Bug fix: reset() wasn't working on file inputs with an ID that contained a dot (#140)
• Moved default values of parameters to the R layer instead of being defined in javascript. This means that RStudio no longer complains of missing arguments and that autocompletion will show default values. (#80)
• Improve efficiency of delay() and reset() functions
• Improve documentation and website (https://deanattali.com/shinyjs)

shinyjs 0.9

2016-12-26

• added support for shinyAce editor as the input for runcodeUI() (#93)
• showLog() no longer needs to be specified in useShinyjs(), and it can be used by just calling it in the server code once (#105)
• fixed bug where showLog() would only show the last message if multiple messages were printed in succession (#99)
• fixed bug where date inputs could not be reset to empty (#100)
• fixed textArea inputs not getting disabled when disabling a parent element
• add showElement()/hideElement()/toggleElement() and addCssClass etc functions as synonyms for functions that are masked by S4 (compromise for #81)
• fixed broken runExample("sandbox") example
• added a website for shinyjs: https://deanattali.com/shinyjs/

2016-11-03

• added runcodeUI() and runcodeServer() functions that you can add to your app in order to run arbitrary R code interactively
• added showLog() function which lets you redirect all JavaScript logging statements to the R console, to make it easier and quicker to debug apps without having to open the JS console (#88)
• onclick and onevent now support callback functions, and the JavaScript Event object is passed to the callback (#92)
• the reset() function now works on file inputs
• added alert() as an alias for info()

• Use updated colourpicker JS library that fixes bugs with new jquery version
• Add reset support for passwordInput and textAreaInput (#78)

shinyjs 0.6.2

2016-07-25

• Improved UI of demo shiny apps and added social media meta tags and github fork ribbons

shinyjs 0.6.1

2016-05-09

• Added selector argument to html() function

shinyjs 0.6

2016-04-24

• info() function: don't include surrounding quotations if not necessary (#59)
• added documentation for how to use shinyjs in HTML templates

shinyjs 0.5.3

2016-04-05

• Fixed bug with extendShinyjs() where it didn't work when using a script and didn't have V8 installed (#64)

shinyjs 0.5.2

2016-03-25

• Added numCols parameter to the colourPicker() gadget

shinyjs 0.5.1

2016-03-23

• Added returnName parameter to colourInput(), which lets you get an R colour name instead of HEX value as the return value (#62)

shinyjs 0.5.0

2016-03-19

shinyjs 0.4.1

2016-01-31

• html() function: don't attempt to change innerHTML if the element does not exist

shinyjs 0.4.0

2016-01-16

• 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

2015-12-14

• small UI change to colourInput demo shiny app

shinyjs 0.2.4

2015-12-01

• Support extendShinyjs() for users that cannot install the V8 package

shinyjs 0.2.3

2015-11-05

• Updated README

2015-09-15

• added 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)
• refactored internally how shinyjs resources are handled so that the resource path is now prefixed with "shinyjs" or "shinyjs-extend" instead of a random string

shinyjs 0.2.1

2015-09-13

• add a debug parameter to useShinyjs that will cause detailed debugging messages to be printed to the JavaScript console when turned on

shinyjs 0.2.0

2015-09-05

• version bump for CRAN submission

shinyjs 0.1.4

2015-09-05

• refactor JavaScript code to remove code duplication and add better internal documentation
• bug fix: disabled now works with all input types
• bug fix: enable/disable did not work on selectInput, sliderInput, and actionButton
• bug fix: resetting a slider input with a range did not reset the end point, only the start point

shinyjs 0.1.3

2015-09-05

• onclick and onevent now work with dynamically generated elements. Not a trivial fix, but enough people requested it that it was important

shinyjs 0.1.2

2015-09-04

Lots of big changes

• added delay function, which allows you to run code after a specified amount of time has elapsed
• BREAKING CHANGE - removed delay 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")))
• added onevent function, which is similar to onclick but can be used for many other different events
• reset now works with dynamically generated elements (inputs that are created with renderUI)
• make disabled work for dynamically generated elements
• removed defunc resettable function

shinyjs 0.1.1

2015-08-19

• better debugging: when a shinyjs JavaScript function is called with a mix of both named and unnamed arguments (which is not allowed), tell the user what function exactly was called. This is done because sometimes a different package doesn't properly namespace its function calls and end up accidentally calling shinyjs functions, which results in weird bugs.
• add comments to the onclick documentation, to make it clear that it can't work with dynamic UIs
• improved documentation

shinyjs 0.1.0

2015-08-12

• add support for 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 server
• add disabled function that initializes a Shiny input in a disabled state
• add a rmd parameter to useShinyjs that lets you use shinyjs inside interactive R markdown documents (default is FALSE to favour regular Shiny apps)
• the bulk of the shinyjs JavaScript code is no longer embeded in the HTML as text and is instead linked to as a file. This makes the Shiny app's HTML much cleaner and smaller
• use htmltools dependency system for handling javascript/css dependencies

shinyjs 0.0.8.3

2015-07-30

• disable/enable now work for downloadButton elements

shinyjs 0.0.8.2

2015-07-23

• You no longer need to define the server function with the session parameter! A shiny server function defined as server = function(input, output) {...} can work with shinyjs

shinyjs 0.0.8.1

2015-07-17

• Fix bug where periods in element names weren't working for some shinyjs functions

shinyjs 0.0.8.0

2015-06-30

• added an option to allow only a predefined list of colours to select from in colourInput (feature request from Hadley and other Twitter users)

shinyjs 0.0.7.0

2015-06-23

• add selector param to the disable/enable/toggleState functions and the addClass/removeClass/toggleClass functions so that multiple elements can be targeted in batch
• added transparentText param to colourInput

shinyjs 0.0.6.6

2015-06-22

• added a demo app using colourInput that's available via runExample and on my shiny server
• add a transparency option to colourInput
• complete refactor of colourInput using a better library that I modified to work well with shiny inputs
• including multiple useShinyjs() 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().

shinyjs 0.0.6.5

2015-06-17

• added 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.

shinyjs 0.0.6.4

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

shinyjs 0.0.6.3

2015-05-28

• added 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.

shinyjs 0.0.6.2

2015-05-27

• added 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 file

shinyjs 0.0.6.0

2015-05-25

• 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

shinyjs 0.0.5.0

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

shinyjs 0.0.4.0

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

shinyjs 0.0.3.3

2015-04-21

CRAN resubmission

shinyjs 0.0.3.0

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

shinyjs 0.0.2.1

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.

shinyjs 0.0.2.0

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.
