php 假如我的页面是这样,很简单 require_once '../config.php'; require_once '../class/DB.class.php'; $db = new DB(HOST, UNAME, UPWD, DBNAME, "utf-8"); /*********************取出数据库的前40条记录 **************************/ $sql = "select * from sendmes order by _second desc limit 0,40"; $result = $db->fetchAll($sql); foreach ($result as $val){ echo $val["_name"].$val["_mood"]."对".$val["_target"]."说道:".$val["_content"]."".""; } ?>目前我是这样来刷新的:怎么用ajax实现页面不刷新页面,显示最近记录
