Question

我想将菜单列表中的specefic类分配给它的子锚点。

例如：

<li class="icon-home list-item">
    <a href="index.php">Home</a>
</li>

我想将上面的输出转换为此（从列表中删除类icon-home并将其分配给其子锚点）：

<li class="list-item">
    <a class="icon-home" href="index.php">Home</a>
</li>

我想做什么？ 在wordpress菜单数组中搜索匹配的类icon-，然后将其设置为其子锚，然后从列表中取消设置。

我使用的代码在菜单数组中搜索类divider，然后将其转换为class =“divider”的新列表。这是代码：

// managing divider: add divider class to an element to get a divider before it.
$divider_class_position = array_search('divider', $classes);
if($divider_class_position !== false){
    $output .= "<li class=\"divider\"></li>\n";
    unset($classes[$divider_class_position]);
}

这是我的所有wordpress菜单覆盖代码，请在回答之前看看：

Answer 1

你必须寻找：

$item_output .= '<a'. $attributes .'>';

并将其替换为：

$item_output .= '<a'. $attributes .' class="'.$classes[0].'">';

现在它将<li class="icon-home list-item">更改为<a href="index.php" class="icon-home">

Answer 2

On $ attributes只显示链接活动和悬停效果，链接中没有任何特定的类定义。
