public function add(){<br />		$this->lottory_record_db=M('Lottery_record');<br />		$this->lottory_db=M('Lottery');<br />		 if($_POST['action'] ==  'add' ){<br />			$lid 				= $this->_post('lid');<br />			$wechaid 			= $this->_post('wechaid');<br />			//$data['sn']			= $this->_post('sncode');<br />			$data['phone'] 		= $this->_post('tel');<br />			//$data['prize']		= $this->_post('winprize');<br />			$data['wecha_name'] = $this->_post('wxname');<br />			//$data['time']		= time(); <br />			//$data['islottery']	= 1;<br />			//$data['usenums']	= 1;			<br />			$rid=intval($this->_post('rid'));<br />			if (!$rid){<br />				$thisRecord=$this->lottory_record_db->where(array('lid'=>$lid,'wecha_id'=>$wechaid,'islottery'=>1))->find();<br />				$rid=$thisRecord['id'];<br />			}<br />			$rollback = $this->lottory_record_db->where(array('lid'=>$lid,'wecha_id'=>$wechaid,'id'=>$rid))->save($data);<br />			$record=$this->lottory_record_db->where(array('id'=>$rid))->find();<br />			echo'{"success":1,"msg":"恭喜！尊敬的<font color=red>'.$data['wecha_name'].'</font>请您保持手机通畅！你的领奖序号:<font color=red>'.$record['sn'].'</font>"}';<br />			exit;	<br />		}<br />	}

------解决方案--------------------
if($_POST['action'] == 'add' ){
条件 $_POST['action'] == 'add' 不成立，所以 echo 不执行
------解决方案--------------------

<br /><br />var_dump($_POST['action']);//输出看看值是什么？确定条件成立？<br /><br />

------解决方案--------------------
var_dump($_POST['action']);
------解决方案--------------------
那你输出的只是一个 json 串，需要 js 代码去解析呀
