Convert php to js

Litalino

return '<span class="bbcode-hide-content login"> ' .
            $this->translator->trans('imeepo-more-bbcode.forum.login_to_see',
                array(
                    '{login}' => '<a href="javascript:void(0);" class="login2see_login">' . $this->translator->trans('core.forum.header.log_in_link') . '</a>',
                )
            ) . '</span>';
