javascript - 在Google map 上显示和隐藏标记

我正在尝试为我的项目开发具有显示/隐藏标记功能的地图。但是我对javascript没有足够的了解。所以我现在在谷歌上找了一段时间。并看到许多与此相关的帖子。现在我正在使用post shows here中的代码

在那个帖子地图上很好，但是这个帖子有些不足。

它仅显示标记，但在再次单击复选框时不会隐藏。
一次只显示一个类别

最佳答案

Please check this code it should be working for you.

在这里，您只需要添加jquery版本文件。
   并只需检查复选框是否单击该位置
   当您需要将visible设置为true时，否则为false
