加载地图和标记时自动打开 Google 地图 V2 InfoWindow

发布于 2024-12-01 22:29:22 字数 1316 浏览 2 评论 0原文

如何在地图加载时调用标记的信息窗口来打开。由于某种原因，Google 文档仅显示如何响应点击操作。我不太擅长 JavaScript，所以任何帮助将不胜感激。谢谢！

这是我当前的代码，但由于某种原因，没有出现地图。但没有错误可以帮助我找出问题所在......

原文

How do you call a markers' infowindow to open when the map loads. For some reason the Google documentation only shows how to respond to a click action. I'm not very good with JavaScript so any help would be appreciated. Thanks!

this is my current code, but for some reason, no map appears. But there is no error to help me pinpoint the problem...
