How to have cursor change with buttonclick

Question

I have set up a switcher on my website to toggle between normal mouse / pointer & a Lego hand as a cursor and a head as pointer. However, I can only get the cursor to show when clicking the switcher. How can I also add this pointer

(cursor: url(https://cdn.shopify.com/s/files/1/0571/7137/8349/files/pointer.png?v=1644096049), pointer;)

It should be assigned to the following classes:

a, button, input, input, button, a, input, .slider, .round

I have then also added a snippet, which lets the switcher / checkbox stay on checked... (You can see that on this video [password is 12345678]: https://easyupload.io/gknxoi)

However after a reload of the page for example, the switcher stays on checked, but the cursor doesn't show up...

var cbs = document.querySelectorAll('input[type=checkbox]');
for (var i = 0; i < cbs.length; i++) {
  cbs[i].addEventListener('change', function() {
    if (this.checked) {
      document.body.style.cursor = "url(https://cdn.shopify.com/s/files/1/0571/7137/8349/files/cursor.png?v=1644096068), auto";
    } else {
      document.body.style.cursor = "default";
    }
  });
}


$(function() {
  var test = localStorage.input === 'true' ? true : false;
  $('input').prop('checked', test || false);
});

$('input').on('change', function() {
  localStorage.input = $(this).is(':checked');
  console.log($(this).is(':checked'));
});

Answer 1

Is this what you are looking for?

a, input, button, .slider, .round {
  margin: 15px;
  cursor:url(https://cdn.shopify.com/s/files/1/0571/7137/8349/files/pointer.png?v=1644096049), auto;
}

<input type="button" value="lego"/>
<a href="http://google.com" target="_blank">link to google.com</a>

Use document.querySelector('html') instead of document.body will make it work.

Also, use cursor: auto instead of cursor: default

var cbs = document.querySelectorAll('input[type=checkbox]');
for (var i = 0; i < cbs.length; i++) {
  cbs[i].addEventListener('change', function() {
    if (this.checked) {
      document.querySelector('html').style.cursor= ' url(https://cdn.shopify.com/s/files/1/0571/7137/8349/files/cursor.png?v=1644096068), auto'
      document.querySelector('label').style.cursor = ' url(https://cdn.shopify.com/s/files/1/0571/7137/8349/files/cursor.png?v=1644096068), auto'
    } else {
       document.querySelector('html').style.cursor = "auto";
      document.querySelector('label').style.cursor = 'auto'
    }
    
  });
}

.switcheronheader {
  position: relative;
  display: inline-block;
  width: 30px;
  height: 17px;
  margin-bottom: 2px;
}

.mouseswitcher {
  /*   border-left: 1px solid #248751; */
  padding-left: 20px;
}

.switcheronheader input {
  opacity: 0;
  width: 0;
  height: 0;
}

.slider {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ccc;
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 13px;
  width: 13px;
  left: 2px;
  bottom: 2px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

input:checked+.slider {
  background-color: #248751;
}

input:focus+.slider {
  box-shadow: 0 0 1px #2196F3;
}

input:checked+.slider:before {
  -webkit-transform: translateX(13px);
  -ms-transform: translateX(13px);
  transform: translateX(13px);
}

.slider.round {
  border-radius: 34px;
