此代码执行以下操作：

  • 单击项目行中的“删除”-> 删除项目行
  • 单击类别行中的“删除”-> 删除类别行和所有项目行（在所有表中）

需要它执行以下操作：

  • 单击项目行中的“删除”-> 删除项目行（完美运行）
  • 单击类别行中的“删除”-> 删除类别行和该类别行内的所有项目（还可以）

你能改变HTML吗？

<tbody>如果 HTML为每个类别使用标签，jQuery 会更容易（并且 HTML 更具描述性） ，如下所示：

<table class="stats" width="100%">
    <tbody>
        <tr class="category">
            <th scope="rowgroup" colspan="2">Costumes<br /><small>Make your character look uniqe</small></th>
            <td width="80"><a href="#" class="delete" id="category:1">Delete</a><br />Invisible</td>
        </tr>
        <tr class="item">
            <td>Godly Weapon<br /><small>Super wepons of gods</small><br /><small>images/godly_weapon.png</small></td>
            <td width="120">1000 Athen Coins<br />$1 Paypal</td>
            <td width="80"><a href="#" class="delete" id="item:1:1">Delete</a><br />Invisible</td>
        </tr>
        ...
    </tbody>
    <tbody>
        <tr class="category">
            <th scope="rowgroup" colspan="2">Costumes<br /><small>Make your character look uniqe</small></th>
            <td width="80"><a href="#" class="delete" id="category:2">Delete</a><br />Invisible</td>
        </tr>
        <tr class="item">
            <td>Godly Weapon<br /><small>Super wepons of gods</small><br /><small>images/godly_weapon.png</small></td>
            <td width="120">1000 Athen Coins<br />$1 Paypal</td>
            <td width="80"><a href="#" class="delete" id="item:2:1">Delete</a><br />Invisible</td>
        </tr>
        ...
    </tbody>
</table>

然后你的 jQuery 可以像这样重写：

    <script type="text/javascript">                                         
            $(document).ready(function() {
                    $("tr.item .delete").click(function(){
                            $.post("do.php", { what: "delete", q: $(this).attr("id") });
                            $(this).parent().parent().fadeOut("fast");
                    });

                    $("tr.category a.delete").click(function(e){
                            $(this).parents('tbody').fadeOut("fast");
                    });

            });
    </script>

$("tr.category a.delete").click(function(e){

  e.preventDefault();

  // find the row
  var $tr = $(this).parent("tr:first");

  // find the next row with class 'category'
  var $nextcategory = $tr.next("tr.category");

  // select next 'item' rows after next of the next 'category' row
  var $nextitemrows = $nextcategory.next('tr.category').nextAll('tr.item');

  // remove next 'item' rows before next of the next 'category' row
  $nextcategory.nextAll("tr.item").not( $nextitemrows ).remove();

  // remove next category
  $nextcategory.remove();
});


$("tr.item a.delete").click(function(e){

  e.preventDefault();

  // find the row & remove itself
  $(this).parent("tr:first").remove();
});

不知道您使用的是什么 jQuery 版本，或者您是否正在使用 IE 进行测试，但是使用 fadeIn/fadeOut 的 jQuery 1.3.2 存在一个错误，可能会导致问题：

http://dev.jquery.com/ticket/4440

不知道这是否是问题，但我想我会提到它。
