我有一个包含一些行的表，向您展示所有代码有点困难，但我会给您一个示例：

<tr id="<?=$row['slug'];?>" class="gradeX <? if($row['parent_name']!=''){?>child<?}?>">
<td id="<?=$row['id'];?>" class="expand-parent"><? if($row['parent_name']==''){?>+<?}?></td>
<td><span id="<?=$row['id'];?>" class="edit-title"><?=$row['title'];?></td>
<td><span id="<?=$row['id'];?>" class="edit-slug"><?=$row['slug'];?></td>
<td><span id="<?=$row['id'];?>" class="edit-parent"><? if($row['parent_name']){ ?><?=$row['parent_name'];?> (ID: <?=$row['parent'];?>)<? } ?></td>
<td id="<?=$row['id'];?>" class="edit-uri"><?=$row['uri'];?></td>
<td id="<?=$row['id'];?>" class="edit-perms"><?=$row['perms'];?></td>
<td>    
<div class="toggle-button" data-toggleButton-style-enabled="success">
<input type="checkbox" class="toggle-perm" id="<?=$row['id'];?>"<?=$cl;?> />
</div>
</td>
</tr>

这是一个循环，并产生几百个“父”行和几千个“子”行。

我有一些看起来像这样的 jquery：

$('.child').toggle();
            $('.expand-parent').click(function(){
                $(this).closest(".child").toggle();
            });

基本上我想做的是一旦你触发了.expand-parent点击功能，它就会切换（显示）属于被点击的父级的子级。告诉jQuery哪些tr孩子属于每个tr父母并相应地切换的最佳方法是什么？

在具有父级的行上，我将添加一个包含父级 ID 的属性。

例子：

<tr id="cbm" class="gradeX" data-parentid="1">

然后你可以像这样编写 jQuery 事件：

var $this = $(this);
var id = $this.attr('id');
$(this).parents('table').find('tr[data-parentid='+id+']').toggle();

注意： parents('table') 遍历表元素 find(..) 定位所有属性 data-parentid 设置为 id 的 tr 元素。

拥有多个具有相同 id 的元素是非法的，所以我会摆脱它们。最干净的方法是将其移动到 tr 元素。
