Javascript 在标记上切换圆单击
我有一些标记是通过一系列的电线放置的。在这些标记周围有半径圆。我试图仅在单击相关标记时显示圆圈,然后在关闭信息框时隐藏。现在,无论是否单击标记,圆圈都会显示。我不确定我做错了什么。有人能告诉我我忽略了什么吗 -谢谢Javascript 在标记上切换圆单击,javascript,google-maps,google-maps-api-3,Javascript,Google Maps,Google Maps Api 3,我有一些标记是通过一系列的电线放置的。在这些标记周围有半径圆。我试图仅在单击相关标记时显示圆圈,然后在关闭信息框时隐藏。现在,无论是否单击标记,圆圈都会显示。我不确定我做错了什么。有人能告诉我我忽略了什么吗 -谢谢 function initialize() { var locations = [ ['Siren 1', 32.832, -96.629, 1], ['Siren 2', 32.827, -96.644, 2], ['Siren 3', 3

单击标记时,我看不到任何显示圆圈的代码。发布的代码创建了标记和圆,并在创建时显示圆({map:map}这样做)。单击标记时,您看不到任何显示圆的代码,因为这是我遇到的问题。我尝试了很多不同的方法。我已经做了很多搜索,列出了很多。我需要将一个点击事件分配给点击标记时将显示的圆圈,但我没有任何成功。因此我请求帮助。我不确定还能补充什么信息。
