根据动态值选择和取消选择复选框。

Question

如果输入类型复选框中的类和部分，我有列表。 所有的值类和 id 都是动态的。如何调用我选择和取消选择所有复选框，如

如果我选择“第一类”，它的所有部分都会被选中

<table class="table table-striped table-bordered table-hover dataTable no-footer">
<thead>
<tr>
<th class="col-lg-2">#</th>
<th class="col-lg-2">Classes</th>
<th class="col-lg-2">Sections</th>

JS代码：

$(document).on('click', '.cls', function() {    

if($(this).parents('td').next("td").find('input').is(':checked')) {
    $(this).parents('td').next("td").find('input').prop('checked', false);
} else {  
   $(this).parents('td').next("td").find('input').prop('checked', true);
}

});
