下面是html测试代码：

调用时有个ajax请求被注释了，它返回一个json数据，我用php读数据库来测试的，如果需要，代码如下：
复制代码 代码如下:
<?php

function __construct(){
$this->conn = mysql_connect("localhost","root","pwd") or die("Cant't connect host~");
mysql_select_db("studentinfo",$this->conn) or die("Cant't select database~");
}
public function data_list($s){
$this->rs=mysql_query("select sno from student where sno like '$s%'") or die("Can't fetch~");
$dataList=array();
while($row = mysql_fetch_array($this->rs,MYSQL_ASSOC)){
array_push($dataList,$row);
}
return $dataList;
}
}
$search= isset($argv[1]) ? $argv[1] :
( isset($_GET['search']) ? $_GET['search'] : '' ) ;
$fetch=new DataFetch();
$data=$fetch->data_list($search);
echo '[';
foreach ($data as $key=>$value){
echo "\n\t";
echo '"'.$value['sno'].'"';
if( $key!=count($data)-1 ) echo ','; else echo "\n";

《魔兽世界》大逃杀！60人新游玩模式《强袭风暴》3月21日上线
暴雪近日发布了《魔兽世界》10.2.6 更新内容，新游玩模式《强袭风暴》即将于3月21 日在亚服上线，届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。
艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕，并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时，他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中，玩家将会进入一个全新的海盗主题大逃杀式限时活动，其中包含极高的风险和史诗级的奖励。
《强袭风暴》不是普通的战场，作为一个独立于主游戏之外的活动，玩家可以用大逃杀的风格来体验《魔兽世界》，不分职业、不分装备（除了你在赛局中捡到的），光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式，玩家在加入海盗主题的预赛大厅区域前，可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹，《巨龙崛起》和《魔兽世界：巫妖王之怒 经典版》的玩家都可以获得奖励。
