今天为大家分享一个删除WordPress菜单中多余的CLASS和ID沉余方法。
wordpress增加模板菜单方法
在functions.php文件加上以下代码，
if(function_exists(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’register_nav_menus\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’)){
register_nav_menus(
array(
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’header-menu\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => __( \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’菜单名字A\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ ),
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’footer-menu\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => __( \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’菜单名字B\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ ),
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’sider-menu\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => __(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’菜单名字C\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’)
)
);
}
最简单的调用方式，前台加上下面代码
<?php wp_nav_menu(); ?>
也可以对这个菜单进行更多的控制，代码如下
<?php wp_nav_menu(
array(
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’theme_location\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ //指定显示的导航名，如果没有设置，则显示第一个
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’menu\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’header-menu\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’container\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’nav\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, //最外层容器标签名
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’container_class\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’primary\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, //最外层容器class名
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’container_id\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,//最外层容器id值
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’menu_class\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’sf-menu\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, //ul标签class
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’menu_id\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’topnav\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,//ul标签id
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’echo\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => true,//是否打印，默认是true，如果想将导航的代码作为赋值使用，可设置为false
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’fallback_cb\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’wp_page_menu\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,//备用的导航菜单函数，用于没有在后台设置导航时调用
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’before\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,//显示在导航a标签之前
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’after\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,//显示在导航a标签之后
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’link_before\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,//显示在导航链接名之后
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’link_after\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,//显示在导航链接名之前
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’items_wrap\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'<ul id=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”%1$s\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”>%3$s</ul>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’depth\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => 0,////显示的菜单层数，默认0，0是显示所有层
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’walker\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’// //调用一个对象定义显示导航菜单 ));
?>
如何删除菜单选择器沉余
默认Wordpress菜单生成的Html代码
代码在菜单列表中li有多个Id,也有多个Class的类，而且定义整个菜单样式，根本不需要这么多选择器，下面介绍删除Wordpress沉余选择器的方法，代码如下
add_filter(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’nav_menu_css_class\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’my_css_attributes_filter\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, 100, 1); //删除Class选择器
add_filter(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’nav_menu_item_id\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’my_css_attributes_filter\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, 100, 1); //删除Id选择器
add_filter(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’page_css_class\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’my_css_attributes_filter\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, 100, 1);
function my_css_attributes_filter($var) {
return is_array($var) ? array_intersect($var, array(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’current-menu-item\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’current-post-ancestor\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’current-menu-ancestor\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’current-menu-parent\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’)) : \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’; //删除当前菜单的四个选择器
}
