VisualizaçõesJquery checkbox function get ID based on biggest data
I'm having trouble finding the jquery checkbox function to get the ID based on the largest data. The selected data, of course, is clicked and checked, not unchecked.
HTML:
<input type="checkbox" class="checkbox" name="id[]" data-id="001" data-weight="10" value="001"/> A (10 kg) <br>
<input type="checkbox" class="checkbox" name="id[]" data-id="002" data-weight="20" value="002"/> B (20 kg) <br>
<input type="checkbox" class="checkbox" name="id[]" data-id="003" data-weight="30" value="003"/> C (30 kg) <br>
<input type="checkbox" class="checkbox" name="id[]" data-id="004" data-weight="40" value="004"/> D (40 kg) <br>
<br>
<br>
<div>Heaviest Weight</div>
<input type="text" id="getWeight">
<div>ID the Heaviest Weight</div>
<input type="text" id="getId"><br>
Javascript:
$(document).ready(function() {
var maximum = null;
$(".checkbox").click(function(){
var value = $(this).data('weight');
maximum = (value > maximum) ? value : maximum;
id = $(this).data('id');
$('#getId').val(id);
$('#getWeight').val(maximum);
});
});

Try looping all checked checkbox, and compare each weight, every change of each checkbox.
$(document).ready(function() {
$(".checkbox").change(function(){
var checkboxes = document.querySelectorAll(".checkbox:checked");
var maximum = 0;
var maximumID = 0;
checkboxes.forEach(checkbox => {
var value = $(checkbox).data('weight');
if( value > maximum ){
maximum = value;
maximumID = $(checkbox).data('id');
}
});
$('#getId').val(maximumID);
$('#getWeight').val(maximum);
});
});
