我扩展了Walker\\u Nav\\u菜单，将超链接转换为锚定，因为我正在创建一页网站。代码如下：

class description_walker extends Walker_Nav_Menu{
  function start_el(&$output, $item, $depth= 0 , $args = array(), $id = 0){
       global $wp_query;
       $indent = ( $depth ) ? str_repeat( "\\t", $depth ) : \'\';
       $class_names = $value = \'\';
       $classes = empty( $item->classes ) ? array() : (array) $item->classes;
       $class_names = join( \' \', apply_filters( \'nav_menu_css_class\', array_filter( $classes ), $item ) );
       $class_names = \' class="\'. esc_attr( $class_names ) . \'"\';
       $output .= $indent . \'<li id="menu-item-\'. $item->ID . \'"\' . $value . $class_names .\'>\';
       $attributes  = ! empty( $item->attr_title ) ? \' title="\'  . esc_attr( $item->attr_title ) .\'"\' : \'\';
       $attributes .= ! empty( $item->target )     ? \' target="\' . esc_attr( $item->target     ) .\'"\' : \'\';
       $attributes .= ! empty( $item->xfn )        ? \' rel="\'    . esc_attr( $item->xfn        ) .\'"\' : \'\';
       if($item->object == \'page\')

       {
            $varpost = get_post($item->object_id);
            if(is_home()){
              $attributes .= \' href="#\' . $varpost->post_name . \'"\';
            }else{
              $attributes .= \' href="\'.home_url().\'/#\' . $varpost->post_name . \'"\';
            }
       }
       else
            $attributes .= ! empty( $item->url )        ? \' href="\'   . esc_attr( $item->url        ) .\'"\' : \'\';
        $item_output = $args->before;
        $item_output .= \'<a\'. $attributes .\'>\';
        $item_output .= $args->link_before . apply_filters( \'the_title\', $item->title, $item->ID );
        $item_output .= $args->link_after;
        $item_output .= \'</a>\';
        $item_output .= $args->after;
        $output .= apply_filters( \'walker_nav_menu_start_el\', $item_output, $item, $depth, $args );
 }
}
