我试图从CDN加载jquery，而不是用wordpress本机加载。在我的功能中。php我已经完成了如下操作，确保它只发生在前端：

function replace_jquery() {
    if (!is_admin()) {
        wp_deregister_script(\'jquery\');
        wp_register_script(\'jquery2\', \'https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js\');
        wp_enqueue_script(\'jquery2\');
    }
}
add_action(\'init\', \'replace_jquery\');

Notice: wp_deregister_script was called <strong>incorrectly</strong>. 
Do not deregister the <code>jquery</code> script in the administration area. 
To target the front-end theme, use the <code>wp_enqueue_scripts</code> hook.
