如果将本地化脚本函数挂接到wp_enqueue_scripts, 然后您将可以访问global $post 变量只要您在“wp”时或之后选择挂钩，您就应该可以访问global $post.

<?php
add_action(\'wp_enqueue_scripts\', \'YOUR_NAME_scripts\'); 

function YOUR_NAME_scripts() {

            wp_enqueue_script(\'YOUR_NAME-js\');

            global $post;
            $params = array(
                \'site_url\' => site_url(),
                \'admin_ajax_url\' => admin_url(\'admin-ajax.php\'),
                \'post_id\' => $post->ID
            );

            wp_localize_script( \'jquery\', \'YOUR_NAME\', $params );

}
