jquery - wordpress ajax menu - move 'active' css tag from to

Answer 1

この行を変更してみてください：

echo '<li><a href="' . $gdl_is_home_url . '#section-n' . $section_number . '" id="nav-section' . $section_number . '" class="anchor' . $active . $gdl_is_home_class . '" >';

に：

echo '<li  class="' . $active . '"><a href="' . $gdl_is_home_url . '#section-n' . $section_number . '" id="nav-section' . $section_number . '" class="anchor' . $gdl_is_home_class . '" >';
