How it works
iCheck works with checkboxes and radio buttons like a constructor. It wraps each input with a div, which may be customized by you or using one of the available skins. You may also place inside that div some HTML code or text using insert
option.
For this HTML:
Foo Bar Bar
With default options you'll get nearly this:
Foo Bar Bar
By default, iCheck doesn't provide any CSS styles for wrapper divs (if you don't use skins).
Options
These options are default:
// 'checkbox' or 'radio' to style only checkboxes or radio buttons, both by default handle: '' // base class added to customized checkboxes checkboxClass: 'icheckbox' // base class added to customized radio buttons radioClass: 'iradio' // class added on checked state (input.checked = true) checkedClass: 'checked' // if not empty, used instead of 'checkedClass' option (input type specific) checkedCheckboxClass: '' checkedRadioClass: '' // if not empty, added as class name on unchecked state (input.checked = false) uncheckedClass: '' // if not empty, used instead of 'uncheckedClass' option (input type specific) uncheckedCheckboxClass: '' uncheckedRadioClass: '' // class added on disabled state (input.disabled = true) disabledClass: 'disabled' // if not empty, used instead of 'disabledClass' option (input type specific) disabledCheckboxClass: '' disabledRadioClass: '' // if not empty, added as class name on enabled state (input.disabled = false) enabledClass: '' // if not empty, used instead of 'enabledClass' option (input type specific) enabledCheckboxClass: '' enabledRadioClass: '' // class added on indeterminate state (input.indeterminate = true) indeterminateClass: 'indeterminate' // if not empty, used instead of 'indeterminateClass' option (input type specific) indeterminateCheckboxClass: '' indeterminateRadioClass: '' // if not empty, added as class name on determinate state (input.indeterminate = false) determinateClass: '' // if not empty, used instead of 'determinateClass' option (input type specific) determinateCheckboxClass: '' determinateRadioClass: '' // class added on hover state (pointer is moved onto input) hoverClass: 'hover' // class added on focus state (input has gained focus) focusClass: 'focus' // class added on active state (mouse button is pressed on input) activeClass: 'active' // adds hoverClass to customized input on label hover and labelHoverClass to label on input hover labelHover: true // class added to label if labelHover set to true labelHoverClass: 'hover' // increase clickable area by given % (negative number to decrease) increaseArea: '' // true to set 'pointer' CSS cursor over enabled inputs and 'default' over disabled cursor: false // set true to inherit original input's class name inheritClass: false // if set to true, input's id is prefixed with 'iCheck-' and attached inheritID: false // set true to activate ARIA support aria: false // add HTML code or text inside customized input insert: ''
There's no need to copy and paste all of them, you can just mention the ones you need:
;
You can choose any class names and style them as you want.
Initialize
Just include icheck.js
after jQuery v1.7+ (or Zepto [polyfill, event, data]).
iCheck supports any selectors, but handles only checkboxes and radio buttons:
// customize all inputs (will search for checkboxes and radio buttons); // handle inputs only inside $('.block'); // handle only checkboxes inside $('.test'); // handle .vote class elements (will search inside the element, if it's not an input); // you can also change options after inputs are customized;
Indeterminate
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" 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.
Callback name | When used |
---|---|
ifClicked | user clicked on a customized input or an assigned label |
ifChanged | input's "checked", "disabled" or "indeterminate" state is changed |
ifChecked | input's state is changed to "checked" |
ifUnchecked | "checked" state is removed |
ifToggled | input's "checked" state is changed |
ifDisabled | input's state is changed to "disabled" |
ifEnabled | "disabled" state is removed |
ifIndeterminate | input's state is changed to "indeterminate" |
ifDeterminate | "indeterminate" state is removed |
ifCreated | input is just customized |
ifDestroyed | customization is just removed |
Use on()
method to bind them to inputs:
;
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'; // remove 'checked' state; // toggle 'checked' state; // change input's state to 'disabled'; // remove 'disabled' state; // change input's state to 'indeterminate'; // remove 'indeterminate' state; // apply input changes, which were done outside the plugin; // remove all traces of iCheck;
You may also specify some function, that will be executed on each method call:
;
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
orvisibility: 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
March 03, 2014
- Better HiDPI screens support @ddctd143
v2.0 release candidate)
January 23, 2014 (- 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:
$(input).icheck('data')
to get all the options were used for customization (also stores a current states values -checked
,disabled
andindeterminate
),$('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
orarea
option) - Fast click support - removes a 300ms click delay on mobile devices without any dependencies (iCheck compatible with the
fastclick
plugin), see thetap
option - Ability to ignore customization for the selected inputs using
init
option (if set tofalse
) - 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 singlediv
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 thewindow.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
andindeterminateLabelClass
options (mirror
option should be set totrue
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.
