我四处寻找解决方案，但还没有完全找到我正在寻找的东西。

基本上我有一个谷歌地图，其中有几个从 mysql 表生成的标记，然后转换为 xml 以为每个地址创建一个单独的标记。

我想为每个标记创建一个显示在信息框中的单独链接。
目前，当单击标记时，信息框仅显示地址但没有链接。

我已经能够创建一个出现在信息窗口中的链接，但这是每个标记的相同链接。创建的链接必须指向另一个带有地址 ID 的 php 文件，例如：

www.mysite.com/newpage.php?ID=address_ID_from_table

提前致谢！

这是当前代码：

解决方案非常简单：只需将 html 内容生成器移动到 bindInfoWindow 方法中。

这是更新的代码：

    <script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
