jQuery简单：

//first make sure you have jQuery on that page
add_action(\'wp_enqueue_scripts\',\'make_sure_i_have_jquery\');
function make_sure_i_have_jquery(){
    if (!is_admin())
        wp_enqueue_script( \'jquery\' );
}
//then just change the url to you own
    add_action(\'wp_footer\',\'change_comment_form\');
    function make_sure_i_have_jquery(){
        if (!is_admin() && (is_page() || is_single()))
            echo \'<script> $("#commentform").attr("action", "http://yourUrl.com"); </script>\';
    }

将此粘贴到主题的函数中。php：

add_action( \'comment_form_before\', \'my_comment_form_before\' );
function my_comment_form_before() {
    ob_start();
}
add_action( \'comment_form_after\', \'my_comment_form_after\' );
function my_comment_form_after() {
    $html = ob_get_clean();
    $html = preg_replace(
        \'/wp-comments-post.php"/\',
        \'wp-comments-post.php" some_java_script some_tag="some_value"\',
        $html
    );
    echo $html;
}
