ajax + php问题

OX-H

api.ajax({
    url: uuox_http_path + '/info_board/board.php',
    method: 'post',
    cache : 'false',
    timeout : 5,
    dataType : '',
    data : {
           values : {
               diqu : diqu_value,
               zhiye : zhiye_value
           }
     }
}, function(ret, err){
       alert("ret1 = " + JSON.stringify(ret));
       alert("ret2 = " + ret);
});

php  代码
<?php
        include '../dbconfig.php';

        $recruit_add_type = $_POST['diqu'];
        $recruit_class_type = $_POST['zhiye'];
        $sql = "SELECT * FROM chat_history";

        $result=mysql_query($sql);
        while($row = mysql_fetch_array($result)){
         $notifies[]=$row;              
        }

        echo json_encode($notifies, JSON_UNESCAPED_UNICODE);
        mysql_close();
?>

在PHP echo里打出来的结果是 ：

[{"0":"4","pk_id":"4","1":"2222","m_id":"2222","2":"测试数据","recruit_title":"测试数据","3":"2017-11 17:12","recruit_insert_date":"2017-11 17:12","4":"fushan","recruit_add_type":"fushan","5":"fandian","recruit_class_type":"fandian","6":"","recruit_stop_date":""},{"0":"3","pk_id":"3","1":"1111","m_id":"1111","2":"这里是招聘广场","recruit_title":"这里是招聘广场","3":"2017-10 17:12","recruit_insert_date":"2017-10 17:12","4":"shouer","recruit_add_type":"shouer","5":"wangba","recruit_class_type":"wangba","6":"","recruit_stop_date":""}]

不知道为什么在，api.ajax里打出alert的话 没有数据 ！！！  请大神指教。谢谢

解释一下，这段代码是什么意思？
dataType : '',

ret没值 说明err有值嘛 dataType啥也没写，不知道是啥数据类型喽
