【问题描述】:
我正在创建一个可以向用户显示标记组的 Google 地图。说出一个地区的所有餐馆或公园。目前,我已经能够创建一组餐厅和一组公园,每个都有自己的标记颜色。我什至可以通过单击地图下方的文本来隐藏或显示所有标记。但现在我想将标记分成几类,以便我可以根据复选框隐藏或显示它们。代码如下,但这里是我想做的事情:
- 默认情况下地图应该是空白的,没有标记
- 我可以将标记分成各自的类别并隐藏和显示每个类别
- 一次可以显示多个类别
这是我的代码

在您的“要求”列表中,什么是有效的?什么不工作? fiddle of the posted code

3 号目前正在工作。我可以展示公园和餐厅。我希望他们在被触发之前默认不在那里,但我也不知道如何单独隐藏和显示它们。目前对我来说,要么全有,要么全无。
