我写了一个的temper.html页面去调用http://hys2013.sinaapp.com/SQL.php页面的内容,我照着网上的例子来怎么不行啊(页面不弹窗)
temper.html:

<html><head> <script type="text/javascript" src="/jquery/jquery.js"></script><script type="text/javascript">$.post("http://hys2013.sinaapp.com/SQL.php",function(data){ alert("Data Loaded: " + data); });</script></head><body></body></html>
Copy after login


http://hys2013.sinaapp.com/SQL.php:
<?  $mysql = new SaeMysql(); $conn = mysql_connect(SAE_MYSQL_HOST_M.':'.SAE_MYSQL_PORT,SAE_MYSQL_USER,SAE_MYSQL_PASS); //if($conn){ $action="连接成功"; echo "document.write('".$action."');n";		}				 $sql="SELECT  * FROM  `temp` WHERE id = ( SELECT MAX( CAST( id AS UNSIGNED ) ) FROM temp )";//获取最大ID的那一行		 $row=$mysql->getLine($sql); foreach ($row as $key=>$value)    {					            $insert_id=$value;	  break;//目前只需要id所以无需遍历所有值     }echo $insert_id;?> 
Copy after login

jQuery.post第二个参数是附加参数,第三个参数才是回调吧
$.post("http://hys2013.sinaapp.com/SQL.php" , '', function(data){ alert("Data Loaded: " + data); });

刚才看了一下的确是的,但是改了后怎么还不行啊

语法
jQuery.post(url,data,success(data, textStatus, jqXHR),dataType)
参数 描述
url 必需。规定把请求发送到哪个 URL。
data 可选。映射或字符串值。规定连同请求发送到服务器的数据。
success(data, textStatus, jqXHR) 可选。请求成功时执行的回调函数。
dataType
可选。规定预期的服务器响应的数据类型。
默认执行智能判断(xml、json、script 或 html)。


第 8 行以后不要!
改作 echo $row['id'];

还是不行啊, .php页面能正常返回值,问题应该就是在.html页面吧,是不是我上面写的这个$.post函数格式不对(根据一楼的改了)

你原来写的,和#1教你写的都一样。都是正确的写法之一

你可以先不要在 SQL.php 做任何事情,而只是
echo ‘ok’;
这时应弹出一个 ok 对话框
