服务器端
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
