iCheck check if checkbox is checked

I am using iCheck plugin for customizing checkboxes. I need to display certain text when one or more checkbox is checked and hide the text when none are checked.

The code I have currently displays the text on first click but doesn't hide it unless I click 2 more times. I have multiple checkboxes and would like to show text if one of 'em are checked else hide the text. Does anybody have any idea? The plugin has:

ifChecked
ifChanged
ifClicked
ifUnchecked
ifToggled
ifDisabled
ifEnabled.......

callbacks....Here is the plugin function

$('input').iCheck({ 
checkboxClass: 'icheckbox_square-blue',
radioClass: 'iradio_square-blue',
increaseArea: '20%' // optional
});

Here is what I tried..

$('input').on('ifChecked', function(event){
$(".hide").toggle();
});

html

<input type="checkbox">
<div class"hide" style="display:none">Hi there</div>

For those who struggle with this:

const value = $('SELECTOR').iCheck('update')[0].checked;

This directly returns true or false as boolean.

you can get value of checkbox and status by

$('.i-checks').on('ifChanged', function(event) {
    alert('checked = ' + event.target.checked);
    alert('value = ' + event.target.value);
});

Check this :

var checked = $(".myCheckbox").parent('[class*="icheckbox"]').hasClass("checked");

if(checked) {
  //do stuff
}

All callbacks and functions are documented here: http://fronteed.com/iCheck/#usage

$('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 just need to use the callbacks, from the documentation: https://github.com/fronteed/iCheck#callbacks

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

To know if the iCheck box is checked

var isChecked = $("#myicheckboxid").prop("checked");

I wrote some simple thing:

When you initialize icheck as:

$('input').iCheck({
    checkboxClass: 'icheckbox_square-blue',
    radioClass: 'iradio_square-blue',
    increaseArea: '20%' // optional
});

Add this code under it:

$('input').on('ifChecked', function (event){
    $(this).closest("input").attr('checked', true);          
});
$('input').on('ifUnchecked', function (event) {
    $(this).closest("input").attr('checked', false);
});

After this you can easily find your original checkbox's state. I wrote this code for using icheck in gridView and accessed its state from server side by C#.

Simply find your checkBox from its id.

Use this code for iCheck:

$('.i-checks').iCheck({
    checkboxClass: 'icheckbox_square-green',
    radioClass: 'iradio_square-green',
}).on('ifChanged', function(e) {
    // Get the field name
    var isChecked = e.currentTarget.checked;

    if (isChecked == true) {

    }
});

Call

element.iCheck('update');

To get the updated markup on the element

Use following code to check if iCheck is checked or not using single method.

$('Selector').on('ifChanged', function(event){

	//Check if checkbox is checked or not
	var checkboxChecked = $(this).is(':checked');

	if(checkboxChecked) {
		alert("checked");
	}else{
		alert("un-checked");
	}
});

If any one have any interest on multiple icheck(). Then you can go for it with the below one:

$("#mother_checkbox").on("ifChanged", function(){
	    if($(this).is(':checked')) {
        	$('.child_checkbox').prop('checked', true);
        	$('.child_checkbox').iCheck('update');
	    }
	    else{
        	$('.child_checkbox').prop('checked', false);
        	$('.child_checkbox').iCheck('update');
	    }
});

It will Check/Uncheck all the child checkbox. Good Day !

$('input').on('ifChanged', function(event) {
			 if($(".checkbox").is(":checked")) {
			 	$value = $(this).val();
			 }

			 else if($(".checkbox").is(":not(:checked)")) {
			 	$value= $(this).val();
			 }
		});

Use this method:

$(document).on('ifChanged','SELECTOR', function(event){
  alert(event.type + ' callback');
});

this works for me... try it

// Check #x
$( "#x" ).prop( "checked", true );
 
// Uncheck #x
$( "#x" ).prop( "checked", false );

You could wrap all your checkboxes in a parent class and check the length of .checked..

if( $('.your-parent-class').find('.checked').length ){
  $(".hide").toggle();
}
