jQuery提取內容，切換內容，將其包裝在新標簽中

Question

我整天都在嘗試重新排序此菜單，但我是jquery新手。我想做的是：

• 在此菜單的最后一個td.top中，有3個ul.sub li，我希望每個都從那里提取，並將其內容放在td.top中。

• 然后在內容里面有一個div和一個鏈接，我需要切換位置，該鏈接必須在div之前（就像在另一個td.top內部一樣）

• 基本上我嘗試制作3 ul.sub。 li相同（添加相同的類，具有相同的結構等，如td.top的其余部分）

我怎樣才能做到這一點？ 我感謝任何提示。

這是我到目前為止使用的代碼：

$("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");

..在這里，我應該有代碼來提取3 ul.sub li內部的內容，並切換與div的鏈接，然后將其包裝在td.top中。

這是我需要用jquery修改的html：

<table class="topMenu" cellpadding="0" cellspacing="0">
<tbody>
<tr>
    <td class="top">
        <a href="http://localhost/d7t/m/photos/home/" class="top_link"><span class="down bx-def-padding-sec-leftright">Photos</span>

Answer 1

這是很多問題，而不僅僅是一個問題，並且可能不是特別適合Stackoverflow。

您要選擇最后一個帶有類top的td。 這應該使用最后一個子選擇器完成：

$( "table.topMenu td.top:last-child" ) // you won't use this, just showing the hierarchy

然后，在此td中，您要選擇每個帶有class sub的div。

$( "table.topMenu td.top:last-child div.sub" )

那應該選擇您想要的div的所有內容。 然后，您需要選擇同一部分中鏈接的內容，如下所示：

$( "table.topMenu td.top:last-child a.top_link" )

您應該將它們存儲到javascript對象中，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();

這些行會將它們從DOM中刪除，但會保存jQuery對象以供以后使用（請注意，由於這些選擇器將獲得多個DOM元素，因此它們是jQuery對象，而不是DOM元素）。 然后，您應該能夠根據需要將它們附加到適當的選擇器。 您可能還需要致電：

$( "table.topMenu td.top:last-child" ).remove();

以及清理DOM。
