  服务器

  function poll($formData){
    global $db;
    $tmp="";
    $objResponse = new xajaxResponse();
   
    $poll_id = $formData['poll_id'];
    $pollitem_id = $formData['pollitem'];
   
    if($pollitem_id > 0 && $poll_id > 0) {
     $db->query("update ".TBL_POLLITEM." set count=count+1 where pollitem_id = $pollitem_id");                 
    }
   
    $poll = $db->getRow("select * from TBL_POLL where poll_id = $poll_id");
    $pollitems = $db->getAll("select * from TBL_POLLITEM where poll_id=$poll_id");
   
   
    $tmp .="<div align=center>".$poll["title"]."</div><br>";
      for ($i = 0, $count = count($pollitems); $i < $count; $i++) {
        $tmp .="<div align=left>".$pollitems[$i]['content'].": ".$pollitems[$i]['count']."</div>";
      }
    $tmp .="<div align=center>"."<input type="button"  value="返回" onclick="back();">"."</div>";
   
    $objResponse->addAssign("pollresult","innerHTML",$tmp);
    return $objResponse->getXML();
  }

   

  数据库的表如下

  CREATE TABLE TBL_POLL (
    poll_id int(11) unsigned NOT NULL default '0',
    title varchar(100) NOT NULL default '',
    created_date bigint(20) unsigned NOT NULL default '0',
    user_id int(11) unsigned NOT NULL default '0',
    PRIMARY KEY  (poll_id)
  ) TYPE=MyISAM;

  CREATE TABLE TBL_POLLITEM (
    pollitem_id int(11) unsigned NOT NULL default '0',
    poll_id int(11) unsigned NOT NULL default '0',
    content varchar(100) NOT NULL default '',
    count int(11) unsigned NOT NULL default '0',
    PRIMARY KEY  (pollitem_id)
  ) TYPE=MyISAM;

  这个例子中调查的选项只在页面装载时读出投票后在原地显示最新的投票信息不需要弹出窗口
