I have a table with a checkbox in the table head which I want to use to check/uncheck all the checkboxes in my table. This is my code, but it doesn’t work.
$(document).on('change', '#select_products_checkbox', function() {
$('.form-control').toggleClass('selected');
var selectAllProductsIsChecked = $('#select_products_checkbox').prop('checked');
$('.form-control .form-control').each(function(i, v) {
$(v).prop('checked', selectAllProductsIsChecked);
});
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<table class="table table-bordered">
<thead>
<tr>
<td class="col-md-1">
<input class="form-control" type="checkbox" id="select_products_checkbox">
</td>
<td class="col-md-1 text-center">{t}Product ID{/t}</td>
</tr>
</thead>
<tbody>
<tr>
<td>
<input name="{$price_list_products_checkbox}[]" value="{$productID}" class="form-control" type="checkbox">
</td>
<td class="text-center">
{$productID}
</td>
</tr>
</tbody>
</table>>Solution :
if you pass your event into the change function you can just use the currentTarget checked to set your checked prop on your other checkboxes:
$(document).on('change', '#select_products_checkbox', function(e) {
$('.form-control')
.toggleClass('selected', e.currentTarget.checked)
.prop('checked', e.currentTarget.checked);
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<table class="table table-bordered">
<thead>
<tr>
<td class="col-md-1">
<input class="form-control" type="checkbox" id="select_products_checkbox">
</td>
<td class="col-md-1 text-center">{t}Product ID{/t}</td>
</tr>
</thead>
<tbody>
<tr>
<td>
<input name="{$price_list_products_checkbox}[]" value="{$productID}" class="form-control" type="checkbox">
</td>
<td class="text-center">
{$productID}
</td>
</tr>
</tbody>
