我有一个登录页面，其中显示来自自定义帖子类型的所有帖子。我创建了下拉过滤器，用于引入自定义字段和分类法。我想隐藏所有与所选下拉值不匹配的帖子。
该代码先前已在我的网站上编码，并且可以工作，但是我尝试复制第二种帖子类型的代码，但无法正常工作。下拉列表将填充正确的分类法值，但是，当选择任何下拉列表时，它们将不执行任何操作……不进行过滤，不执行任何操作。它们确实可以使用原始代码，但不能使用我复制的代码（请注意，我复制了所有内容，只是更改了帖子类型名称。我认为问题出在JS代码某处，但我不确定。
我在Wordpress functions.php中设置了带有自定义分类法的自定义帖子类型：
<li>
<input type="checkbox" id="f6c9677c-309c-446c-9f78-757467ec7adc">
<label for="f6c9677c-309c-446c-9f78-757467ec7adc">
<span> Testigos de la Valoracion </span>
<button disabled>Button</button>
</label>
</li>然后我注册自定义分类法：
//Charter Content East Type
$charter_labels = array(
'name' => _x('Charter Aircraft East', 'post type general name'),
'singular_name' => _x('Charter Aircraft East', 'post type singular name'),
'add_new' => _x('Add New', 'news-post'),
'add_new_item' => __('Add New Charter Aircraft East'),
'edit_item' => __('Edit Charter Aircraft East'),
'new_item' => __('New Charter Aircraft East'),
'view_item' => __('View Charter Aircraft East'),
'search_items' => __('Search Charter Aircraft East'),
'not_found' => __('No Charter Aircraft found East'),
'not_found_in_trash' => __('No Charter Aircraft East found in Trash'),
'menu_name' => 'Charter Fleet East'
);
$charter_args = array(
'labels' => $charter_labels,
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_menu' => true,
'menu_position' => 5,
'menu_icon' => '/wp-content/themes/avjet/style/img/airplane-admin-icon.png',
'query_var' => true,
'rewrite' => array('slug'=>'private-jet-charter-fleet-east', 'with_front'=>false, 'feeds'=>true, 'pages'=>true),
'capability_type' => 'post',
'has_archive' => true,
'hierarchical' => false,
'supports' => array('title','editor','author','trackbacks','custom-fields','revisions','thumbnail','page-attributes')
);
register_post_type( 'charter-east' , $charter_args );
一切正常。
然后我在前端显示列表：
$c_manufacturer3_labels = array(
'name' => _x( 'Manufacturer / Model', 'taxonomy general name' ),
'singular_name' => _x( 'Manufacturer / Model', 'taxonomy singular name' ),
'search_items' => __( 'Search Manufacturers' ),
'all_items' => __( 'All Manufacturers' ),
'edit_item' => __( 'Edit Manufacturer / Model' ),
'update_item' => __( 'Update Manufacturer / Model' ),
'add_new_item' => __( 'Add New Manufacturer / Model' ),
'new_item_name' => __( 'New Manufacturer / Model' ),
'menu_name' => __( 'Manufacturers' ),
);
$c_manufacturer3_args = array(
'hierarchical' => true,
'labels' => $c_manufacturer3_labels,
'show_ui' => true,
'query_var' => true,
'rewrite' => array('slug' => 'charter-manufacturers3', 'with_front' => true)
);
register_taxonomy('charter-manufacturers3', array('charter-east'), $c_manufacturer3_args);
这也可以正常工作（请注意，清单被拉到“组”中，这是另一种自定义分类法，与“制造商”的注册方式相同）。
最后，如果制造商正确匹配，那么我有一些JS应该在选择结果时过滤结果。选择后不执行任何操作（控制台中没有错误消息）。

对于其他一些下拉列表，JS还有一些其他代码，它们都是自定义分类法或通过Advanced Custom Fields Pro添加到Post类型的自定义字段。除了下拉菜单中隐藏未选择的列表之外，所有部分都起作用。
