<!-- iCheck output format
<div class="adv_filter">
    <li>
        <div class="iradio_square-orange checked" aria-checked="true" aria-disabled="false" style="position: relative;"><input type="radio" name="letter_type" data-custom="Text" value="0" style="position: absolute; top: -20%; left: -20%; display: block; width: 140%; height: 140%; margin: 0px; padding: 0px; border: 0px; opacity: 0; background: rgb(255, 255, 255);"><ins class="iCheck-helper" style="position: absolute; top: -20%; left: -20%; display: block; width: 140%; height: 140%; margin: 0px; padding: 0px; border: 0px; opacity: 0; background: rgb(255, 255, 255);"></ins></div> Text</li>

        <li>
            <div class="iradio_square-orange" aria-checked="false" aria-disabled="false" style="position: relative;"><input type="radio" name="letter_type" data-custom="Text" value="0" style="position: absolute; top: -20%; left: -20%; display: block; width: 140%; height: 140%; margin: 0px; padding: 0px; border: 0px; opacity: 0; background: rgb(255, 255, 255);"><ins class="iCheck-helper" style="position: absolute; top: -20%; left: -20%; display: block; width: 140%; height: 140%; margin: 0px; padding: 0px; border: 0px; opacity: 0; background: rgb(255, 255, 255);"></ins></div> Text</li>

</div> -->

As you see the checked is attached to the div..

    $(document).ready(function () {
        $('input').iCheck({
            checkboxClass: 'icheckbox_square-orange',
            radioClass: 'iradio_square-orange',
            increaseArea: '20%' // optional
        });
        $("li").on("click", "input", function () {
            var val = $(this).val();
            //updateDataGrid(val);
            alert(val);
        });

    });

Question and description

Provided javascript code worked properly before adding the icheck plugin, I am wondering how to get the same result in the icheck plugin. Its simple, on radio click it stores the value in variable later its passed further to functions.

回答1:

Attach a handler to ifChanged event:

$('input').on('ifChecked', function(event){
  alert($(this).val()); // alert value
});

There are 11 ways to listen for changes:

• 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
• ifCreatedinput - is just customized
• ifDestroyed - customization is just removed

Avoid using jquery as much as you can. You can also use code below;

$('input').on('ifChecked', function(event){
    alert(event.target.value); // alert value
});

回答3:

Use this

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

回答4:

$('body').on('ifChecked','.icheck', function(){
//considering icheck is the class of your checkbox and it is getting generated dynamically
});
