Change label when checkbox is checked

Question

I have a lot of listst with checkboxes like so:

Answer 1

$(".filteritem").on('change', function(){
     $(this).closest('label').toggleClass('highlight');
});

FIDDLE

Answer 2

HTML:

<ul class="checkboxlist">
   <li><label><input type="checkbox" id="1"> Lorem Ipsum</label></li>
   <li><label><input type="checkbox" id="223"> Lorem Ipsum</label></li>
   <li><label><input type="checkbox" id="32"> Lorem Ipsum</label></li>
</ul>

JavaScript:

$( '.checkboxlist' ).on( 'click', 'input:checkbox', function () {
   $( this ).parent().toggleClass( 'highlight', this.checked );
});

Notice that I use event delegation, instead of binding the same handler to every check-box.

Answer 3

You are currently trying to call toggleClass on the input element, not the label. You can use parent to get the label:

$(".filteritem").click(function(){
    $(this).parent().toggleClass('highlight');
});
