我正在尝试创建一个包含多个位置的Google地图。地图显示正常，但标记不会出现在每个纬度和经度上。不知道我在这里做错了什么。我在网上找到了代码，只是根据要求进行了调整。如果你能帮助我，我将不胜感激。

你在标记周围缺少一组额外的方括号以使其成为列表列表，目前传递给生成标记的位置参数只是第一点。
应为[['Albia', 41.0157, -92.8094]...['Madison', 43.1188, -89.3204]]。
答案 1 :(得分：1)
这是你的问题：
generateMarkers(
['Albia', 41.0157, -92.8094],
['Algona', 43.0811, -94.2356],
...
)
用
代替generateMarkers(
[
['Albia', 41.0157, -92.8094],
['Algona', 43.0811, -94.2356],
...
]
)
