/**

     * @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);
    }
