我已经对 API v3 的选项卡进行了一些研究,并提出了 infobubble 作为选项卡式 infowindows 的一个好看的来源。我不是想弄清楚我是否可以稍后将选项卡添加到已创建的信息气泡中。我有几个事件从数据库中提取到 xml,然后到 java 脚本以放在地图上,但有些事件共享相同的位置,但其他潜在标记的日期不同。标记或信息窗口是否具有可以迭代的 ID,以检查地图中某个位置的标记是否已存在?然后如果是这种情况,请在 infobubble/infowindow 中添加一个选项卡?
我认为 infoBubble.addTab(title, content)
是这样做的方法,但我怎么知道要将它添加到哪个标记/信息气泡中?
