我的 PHP 代码包含 MYSQL 数据库， HTML 和 javascript CSS 此代码使用户从下拉列表中选择，并根据用户输入，系统将显示一个包含与所请求数据相关的信息的表格，它将弹出谷歌地图，其中包含一个标记以显示位置。
问题是，在用户点击搜索按钮后，系统会显示没有Google地图的表格。
我不知道问题是在 CSS 还是在 javascript 代码中

试试这个让我知道.....
初始化地图时调用addMarker函数....
<script type="text/javascript">
var map,currentPopup;

$lattitude = $row->lattitude;
$longitude = $row->longitude;
$TX = $row->TX;
$RX = $row->RX;
$siteName = $row->locationName;
echo $prependStr;
?>
