To start with, I would advise against implementing this due to usability concerns. However, if you are determined to proceed, here is some guidance.
Creating this effect can be quite challenging but it is achievable. My approach eliminates the necessity of assigning individual IDs to each checkbox.
The key is to utilize an image sprite for the "on" and "off" states, positioning them using the CSS background-position property along with a toggle class. Following this, the provided jQuery code enables you to switch between the image states and update the corresponding checkbox status for form submission. It's worth noting that the actual checkbox remains hidden to maintain functionality while enhancing the visual appearance.
<form>
<input type="checkbox" class="custom" />
</form>
<style type="text/css">
.checkbox {
clear:left;
float:left;
background:url('your_image');
background-position:top;
width:20px;
height:20px;
display:block;
}
.toggled {
background-position:bottom !important;
}
</style>
$(document).ready(function () {
var checkboxes = $('form .custom'),
custom = $('<span></span>').addClass('checkbox');
checkboxes.before(custom);
checkboxes.css('visibility', 'hidden');
$('.checkbox').click(function () {
$(this).toggleClass('toggled');
var isChecked = $(this).next(':checkbox');
var value = isChecked.prop('checked') ? 'true' : 'false';
if (value == 'false') {
isChecked.prop('checked', true);
} else {
isChecked.prop('checked', false);
}
});
});
Adjust the CSS as needed to match your specific requirements. Hopefully, this explanation proves useful as this task can be surprisingly complex.
