I have several checkboxes spread across multiple divs.In all separate div I have a 'select all' checkbox. When that checkbox is selected, I am trying to get all the other ones to be selected related to that pertucular div, and when you deselect the 'select all' one, it deselects the others.
<div class="actions" id="actions" title="Actions">
<div>
<div><input type="checkbox" name="action" id="" class="" value="0" /> Select All</div><br />
<div><input type="checkbox" name="action" id="" class="" value="1" /> <?php echo $lang["actions"][1]; ?></div><br />
<div><input type="checkbox" name="action" id="" class="" value="2" /> <?php echo $lang["actions"][2]; ?></div><br />
<div><input type="checkbox" name="action" id="" class="" value="3" /> <?php echo $lang["actions"][3]; ?></div><br />
</div>
<div>
<div><input type="checkbox" name="action" id="" class="" value="26" />Select All</div><br />
<div><input type="checkbox" name="action" id="" class="" value="27" /> <?php echo $lang["actions"][27]; ?></div><br />
<div><input type="checkbox" name="action" id="" class="" value="28" /> <?php echo $lang["actions"][28]; ?></div><br />
<div><input type="checkbox" name="action" id="" class="" value="29" /> <?php echo $lang["actions"][29]; ?></div><br />
<div><input type="checkbox" name="action" id="" class="" value="30" /> <?php echo $lang["actions"][30]; ?></div><br />
<div><input type="checkbox" name="action" id="" class="" value="31" /> <?php echo $lang["actions"][31]; ?></div>
</div>
</div>
Here is an example
Next time show us at least a minimum of code so that we can help you understand
$('.selectAll').on('click',function(){
let isSelected = $(this).is(':checked');
$(this).parents('.myDiv').find('input[type="checkbox"]').each(function(){
if( isSelected )
$(this).prop('checked',true);
else
$(this).prop('checked',false);
})
})
$('input:not(".selectAll")').on('click',function(){
let selectAllChecked = $(this).parents('.myDiv').find('.selectAll')[0].checked;
let numberInput = $(this).parents('.myDiv').find('input').not('.selectAll').length;
let numberInputChecked = $(this).parents('.myDiv').find('input:checked').not('.selectAll').length;
if( selectAllChecked )
$(this).parents('.myDiv').find('.selectAll')[0].checked = false;
if( numberInput == numberInputChecked)
$(this).parents('.myDiv').find('.selectAll')[0].checked = true;
