Novices don't know much about jquery, please do me a favor.

Newbies don't know much about jquery, please do me a favor.
I wrote a temper.html page to call the contents of the http://hys2013.sinaapp.com/SQL.php page, I follow the online example how not to AH (page does not pop windows)
Temper.html:

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 = "connection succeeded"; echo "document.write ('". $action. "'); n ";}
$sql = "Select  *  from ' temp ' WHERE id = (SELECT MAX (CAST (id as UNSIGNED)] from temp)";//The row that gets the maximum ID
$row = $mysql->getline ($sql);
foreach ($row as $key = $value)
    {      
      $insert _id= $value;
  BREAK;//currently requires only ID so you don't have to traverse all the values
     }
echo $insert _id;

Ask the great God to see how it should be changed.
------Solution--------------------
Jquery.post The second parameter is an additional parameter, and the third parameter is the callback.
$.post ("http://hys2013.sinaapp.com/SQL.php" , '', function (data) {alert ("Data Loaded:" + data);});
