我整天都试着像我需要的那样重新订购这个菜单，但我是jquery的新手。 我想做的是：
在这个菜单的最后一个td.top里面有3个ul.sub li，我希望每个都从那里提取，它的内容放在td.top里。
然后在内容中有一个div和一个链接，我需要切换位置，链接必须在div之前（就像在其他td.top内部一样）
基本上我尝试制作3 ul.sub。 li相同（添加相同的类，具有相同的结构等，就像td.top的其余部分一样）
我该怎么做？ 我很感激任何提示..
这是我到目前为止使用的代码：
$("ul.sub a.more_top_element").removeClass('button more_top_element').addClass("top_link").removeAttr('style').removeAttr('value');
$("ul.sub div").removeClass('more_sub').addClass("sub");
..在这里我应该有代码来提取3 ul.sub li中的内容并用div切换链接，然后将其包装在td.top中。
这是我需要用jquery修改的html：
<table class="topMenu" cellpadding="0" cellspacing="0">

答案 0 :(得分：1)
这是一个很多问题，不仅仅是一个问题，而且可能不太适合stackoverflow。
您想要选择上一个顶级的td。这应该使用last-child选择器完成：
$( "table.topMenu td.top:last-child" ) // you won't use this, just showing the hierarchy
然后，在这个td中，你想要用class sub选择每个div。
$( "table.topMenu td.top:last-child div.sub" )
那应该选择你想要的div的所有内容。然后你需要在同一部分中选择链接的内容，如下所示：
$( "table.topMenu td.top:last-child a.top_link" )
您应该将它们存储到javascript对象中，如下所示：
var divs = $( "table.topMenu td.top:last-child div.sub" ).remove();
var links = $( "table.topMenu td.top:last-child a.top_link" ).remove();
这些行将从DOM中删除它们，但保存jQuery对象供以后使用（注意，由于这些选择器将获得多个DOM元素，因此它们是jQuery对象，而不是此时的DOM元素）。然后，您应该能够根据需要使用适当的选择器附加它们。您可能还想打电话：
$( "table.topMenu td.top:last-child" ).remove();
以及清理DOM。
