}
$("#qu").html(str);
}
});
}
其次就是处理页面(两种方法都用到的)：chuli.php
<?php
$code=$_POST["code"];
require "DB.class.php";
$db=new DB();
$sql="select areacode,areaname from chinastates where parentareacode='{$code}'";
$str=$db->strquery($sql);
echo $str;
最后就是封装的类文件：DB.class.php
function strquery($sql)
{
$db = new MySQLi($this->host,$this->uid,$this->pwd,$this->dbname);
$result = $db ->query($sql);
$arr =$result->fetch_all();
$str="";
foreach($arr as $v)
{
$str=$str.implode("^",$v)."|";
}
$str = substr($str,0,strlen($str)-1);
return $str;
}
}
?>
