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)
$('input').iCheck();

// handle inputs only inside $('.block')
$('.block input').iCheck();

// handle only checkboxes inside $('.test')
$('.test input').iCheck({
  handle: 'checkbox'
});

// handle .vote class elements (will search inside the element, if it's not an input)
$('.vote').iCheck();

// you can also change options after inputs are customized
$('input.some').iCheck({
  // different options
});

Indeterminate

HTML5 allows specifying indeterminate (“partially” checked) state for checkboxes. iCheck supports it 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):

$(‘input’).iCheck(‘check’); — change input’s state to checked

$(‘input’).iCheck(‘uncheck’); — remove checked state

$(‘input’).iCheck(‘toggle’); — toggle checked state

$(‘input’).iCheck(‘disable’); — change input’s state to disabled

$(‘input’).iCheck(‘enable’); — remove disabled state

$(‘input’).iCheck(‘indeterminate’); — change input’s state to indeterminate

$(‘input’).iCheck(‘determinate’); — remove indeterminate state

$(‘input’).iCheck(‘update’); — apply input changes, which were done outside the plugin

$(‘input’).iCheck(‘destroy’); — remove all traces of iCheck

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

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