【问题描述】:
我知道这个问题似乎以前被问过,但我看到的没有一个可以回答我的问题,问题是我从数据库中获取纬度和经度数据时出错并且不能在javascript部分的谷歌地图中显示标记,我可以正常在我的视图中获取我的数据库(lan,lng),但无法将它们打印为谷歌地图上的标记,标记根本不显示,我认为这是因为我把initMap() 中的所有脚本。现在我只想在谷歌地图上显示我的数据库数据(lan,lng)作为标记。任何帮助将不胜感激。原谅我的英语不好

【问题讨论】:
-
您已将“var uluru”定义为一个点,然后再次将其重新定义为点数组(因此您丢失了第一个值),这是错误的。然后将点数组传递给“new google.maps.Marker”,但是,您应该分别用每个点创建一个新标记。

没用,不过还是谢谢老哥的回复
