分析DuxCms之AdminController

 /**
      * 后台模板显示 调用内置的模板引擎显示方法，
      * @access protected
      * @param string $templateFile 指定要调用的模板文件
      * @return void
      */
 protected function adminDisplay($templateFile='') {
         //获取菜单
         $menuList = D('Admin/Menu')->getMenu($this->loginUserInfo,$this->infoModule['cutNav']['url'],$this->infoModule['cutNav']['complete']);
         $this->assign('menuList',$menuList);
         //复制当前URL
         $this->assign('self',__SELF__);
         //嵌套模板
         $common = $this->fetch(APP_PATH.'Admin/View/common.html');
         $tpl = $this->fetch($templateFile);
         echo str_replace('<!--common-->', $tpl, $common);
     }

实现了类似iframe的效果
