javascript - 按主行展开/折叠行分组？

我使用datatables插件对行进行分组，并希望在单击主行时折叠/展开子行。
Jsfiddle和图片示例：
Jsfiddle example

看起来如何

当点击主行时，该行与下一个主行之间的所有行均应折叠。



当我搜索有关此的一些信息时，我找到了一个很好的例子，但是它不能与datatables js插件一起正常工作
CodepenExemple

$(document).ready(function() {
  var groupColumn = 2;
  var table = $('#example').DataTable({
    "columnDefs": [{
      "visible": false,
      "targets": groupColumn
    }],
    "order": [
      [groupColumn, 'asc']
    ],
    "displayLength": 25,
    "drawCallback": function(settings) {
      var api = this.api();
      var rows = api.rows({
        page: 'current'
      }).nodes();

      console.log(typeof rows);

      debugger;

      /*      rows.forEach(function(node) {
                 console.log("rows =" + node);
           }); */



      var last = null;

      api.column(groupColumn, {
        page: 'current'
      }).data().each(function(group, i) {

        if (last !== group) {
          $(rows).eq(i).before(
            '<tr class="group"><td colspan="5">' + group + '</td></tr>'
          );

          last = group;
        }
      });
    }
  });

  // Order by the grouping
  $('#example tbody').on('click', function({
    target
  }) {
    if (target.parentNode.className !== 'group') return;
    //console.log($(this).find('[role=row]'))
    $(this).find('[role=row]').slideToggle()

  });

});

tr.group,
tr.group:hover {
  background-color: #ddd !important;
}

最佳答案

一种简单的实现方法是：

let $next = $(target).parent().next();

while ($next.length && $next.is('[role=row]')) {
    $next.slideToggle();
    $next = $next.next();
};
