ReadMe from Origin

HTML5 allows specifying indeterminate ("partially" checked) state for checkboxes. iCheck supports this for both checkboxes and radio buttons.

You can make an input indeterminate through HTML using additional attributes (supported by iCheck). Both do the same job, but indeterminate="true" may not work in some browsers (like IE7):

indeterminate="true"
<input type="checkbox" indeterminate="true">
<input type="radio" indeterminate="true">

determinate="false"
<input type="checkbox" determinate="false">
<input type="radio" determinate="false">

indeterminate and determinate methods can be used to toggle indeterminate state.

Callbacks

iCheck provides plenty callbacks, which may be used to handle changes.

Use on() method to bind them to inputs:

$('input').on('ifChecked', function(event){
  alert(event.type + ' callback');
});

ifCreated callback should be binded before plugin init.

Methods

These methods can be used to make changes programmatically (any selectors can be used):

// change input's state to 'checked'
$('input').iCheck('check');

// remove 'checked' state
$('input').iCheck('uncheck');

// toggle 'checked' state
$('input').iCheck('toggle');

// change input's state to 'disabled'
$('input').iCheck('disable');

// remove 'disabled' state
$('input').iCheck('enable');

// change input's state to 'indeterminate'
$('input').iCheck('indeterminate');

// remove 'indeterminate' state
$('input').iCheck('determinate');

// apply input changes, which were done outside the plugin
$('input').iCheck('update');

// remove all traces of iCheck
$('input').iCheck('destroy');

You may also specify some function, that will be executed on each method call:

$('input').iCheck('check', function(){
  alert('Well done, Sir');
});

Feel free to fork and submit pull-request or submit an issue if you find something not working.

Comparison

iCheck is created to avoid routine of reinventing the wheel when working with checkboxes and radio buttons. It provides an expected identical result for the huge number of browsers, devices and their versions. Callbacks and methods can be used to easily handle and make changes at customized inputs.

There are some CSS3 ways available to style checkboxes and radio buttons, like this one. You have to know about some of the disadvantages of similar methods:

• inputs are keyboard inaccessible, since display: none or visibility: hidden used to hide them
• poor browser support
• multiple bugs on mobile devices
• tricky, harder to maintain CSS code
• JavaScript is still needed to fix specific issues

While CSS3 method is quite limited solution, iCheck is made to be an everyday replacement covering most of the tasks.

Browser support

iCheck is verified to work in Internet Explorer 6+, Firefox 2+, Opera 9+, Google Chrome and Safari browsers. Should also work in many others.

Mobile browsers (like Opera mini, Chrome mobile, Safari mobile, Android browser, Silk and others) are also supported. Tested on iOS (iPad, iPhone, iPod), Android, BlackBerry and Windows Phone devices.

Changelog

October 10, 2020

• iOS 13 support @markusbroman
• Reformatted changelog @lasseeee
• Fire change event when toggled @rafatmyo

March 03, 2014

• Better HiDPI screens support @ddctd143

January 23, 2014 (v2.0 release candidate)

• Three ways to set an options: global object (window.icheck), data attributes (<input data-checkedClass="checked") and direct JavaScript object ($(input).icheck({ options }))
• Huge performance boost (takes less than 1s to customize 1000 inputs)
• Minimized number of function calls (some slow jQuery functions are replaced with a faster vanilla alternatives without using any dependencies)
• AMD module definition support (both for jQuery and Zepto)
• Unblocked native events - iCheck 2.x doesn't stop your newly or past binded events from being processed
• Pointer events support - full support for phones and tablets that use Windows OS (such as Lumia, HP tablets, desktops with a touch screen, etc)
• WebOS and Firefox OS support
• New methods: $(input).icheck('data') to get all the options were used for customization (also stores a current states values - checked, disabled and indeterminate), $('input').icheck('styler') to get a wrapper div (that's used for customization)
• Better handling of the indeterminate state
• Ability to set callbacks in three ways: global object, direct JavaScript object or using bind method ($(input).on(callback))
• Ability to switch off some of the callbacks when you don't need them (global or per input)
• Inline styles dropped - iCheck won't add any inline styles to the elements until it's highly needed (cursor or area option)
• Fast click support - removes a 300ms click delay on mobile devices without any dependencies (iCheck compatible with the fastclick plugin), see the tap option
• Ability to ignore customization for the selected inputs using init option (if set to false)
• Optimized event bindings - iCheck binds only a few global events for the all inputs (doesn't increase on elements addition), instead of a couple for the each customized element
• Doesn't store tons of arbitrary data (event in jQuery or Zepto cache), defines customized elements by specific classnames
• Extra ins tag is dropped (less DOM modifications), iCheck wraps each input with a single div and doesn't use any extra markup for the any option
• Optimized reflows and repaints on init and state changes
• Better options handling - iCheck will never run a single line of JS to process an options that are off or empty
• Ability to auto customize the ajax loaded inputs without using any extra code (autoAjax option, on by default)
• Auto inits on domready using the specified selector (autoInit option) - searches for .icheck by default. Classnames can be changed using the window.classes object
• Memory usage optimization - uses only a few amount of memory (works well on low-memory devices)
• Betters callbacks architecture - these are fired only after changes are applied to the input
• Ability to set a mirror classes between the inputs and assigned labels using the hoverLabelClass, focusLabelClass, activeLabelClass, checkedLabelClass, disabledLabelClass and indeterminateLabelClass options (mirror option should be set to true to make this happen)
• Fixes some issues of the mobile devices
• Fixes the issues of the wrapper labels, that loose a click ability in some browsers (if no for attribute is set)
• Some other options and improvements
• Various bug fixes

Note: extended docs and usage examples will be available later.
