Adding/removing checkmark to different inputs with

Question

I have three options and if you click on an option a checkmark shows over it, representing the option as selected. I have a limit of 1 set. As of now, the image/current checkmark input needs to be clicked again to remove it, rather than simply being able to click on another option and removing it.

I tried to setup a snippet that replicates what I actually have, but the checkmark isn't showing for some reason. Regardless, I am attempting to incorporate a solution I saw from another post with this: $('').not(this).prop('checked', false);.

I am not sure how to add it to my code to get it to work though. I have tried:

$(this).parents('.product-wrap:first').find('.checkmark-img').fadeBoolToggle(this.checked).not(this).prop('checked', false);

and

$(this).parents('.product-wrap:first').find('.checkmark-img').not(this).prop('checked', false).fadeBoolToggle(this.checked);

Does anyone know how I can get the checkmark inputs to switch when clicking another checkmark input option?

This is the block of code that it is associated with.

$('.calendar-check').on('change', function () {
        //    $('').not(this).prop('checked', false);
        if (!this.checked || $('.calendar-check:checked').length <= limitCal) {
            $(this).parents('.product-wrap:first').find('.checkmark-img').fadeBoolToggle(this.checked);

 //For checkmark
    jQuery.fn.fadeBoolToggle = function (bool) {
        return bool ? this.fadeIn(400) : this.fadeOut(400);
    }
$('.calendar-check').on('change', function () {
        //    $('input.example').not(this).prop('checked', false);
        if (!this.checked || $('.calendar-check:checked').length <= limitCal) {
            $(this).parents('.product-wrap:first').find('.checkmark-img').fadeBoolToggle(this.checked);
        }
});

.product-check, .calendar-check {
  display: none;

Answer 1

If you are trying to have only one checkbox selected you need to add a name (if you want to use radio this works else you need jQuery for checkbox ) that is the same in each input field:

<div>
   <input name="checkMark" type="checkbox" />
</div>
<div>
   <input name="checkMark" type="checkbox" />
</div>
<div>
   <input name="checkMark" type="checkbox" />
</div>

If you are using this code to have only one checkbox checked, then delete this code:

$('.calendar-check').on('change', function () {
        //    $('').not(this).prop('checked', false);
        if (!this.checked || $('.calendar-check:checked').length <= limitCal) {
            $(this).parents('.product-wrap:first').find('.checkmark-img').fadeBoolToggle(this.checked);

and add this one:

$('input.calendar-check').on('click', function(){
    $('input.calendar-check').not(this).attr('checked', false);
})

Basically you're saying whichever one you click, the rest of the inputs will be checked false.
