typecho里themes/../index.php的pageNav,如何跟Widget_Archive的pageNav关联？

user/themes/default文件夹里的index.php，有this->pageNav，而Widget_Archive里也有pageNav，当index.php里执行this->pageNav时，会执行Widget_Archive里的pageNav请问，为什么会这样执行呢？ 我在Widget_Archive里只看到有：require_once $this->_themeDir . $this->_themeFile;登录后复制登录后复制这样一句话。难道是require进来了，就能在前台的index.php文件里，执行后台的pageNav函数？user/themes/default/index.php里的pageNav代码：pageNav('« 前一页', '后一页 »'); ?>"登录后复制登录后复制Widget_Archive里的pageNav代码：/** * 输出分页 * * @access public * @param string $prev 上一页文字 * @param string $next 下一页文字 * @param int $splitPage 分割范围 * @param string $splitWord 分割字符 * @param string $template 展现配置信息 * @return void */public function pageNav($prev = '«', $next = '»', $splitPage = 3, $splitWord = '...', $template = '') { if ($this->have()) { $hasNav = false; $default = array( 'wrapTag' => 'ol', 'wrapClass' => 'page-navigator' ); if (is_string($template)) { parse_str($template, $config); } else { $config = $template; } $template = array_merge($default, $config); $total = $this->getTotal(); $this->pluginHandle()->trigger($hasNav)->pageNav($this->_currentPage, $total, $this->parameter->pageSize, $prev, $next, $splitPage, $splitWord); if (!$hasNav && $total > $this->parameter->pageSize) { $query = Typecho_Router::url($this->parameter->type .
