var lo="广东省", lc="";
var localAddress=

封装方法如下（百度api）:

/*
 * 通过ip获取归属地
 *
 * */
function getIpAddress($ip=''){
    if(empty($ip)){
        return '请输入IP地址';
    }
    $res = @file_get_contents('http://opendata.baidu.com/api.php?query='.$ip.'&co=&resource_id=6006&oe=utf8');
    $result = json_decode($res,true);
    if(empty($result['data'])){
        return false;
    }
    return $result['data'];
}
