我知道之前有很多次问过这个问题,但是我见过的其他答案似乎都没有帮助我。基本上,地图的容器显示(作为页面上500x300px的空白区域),但没有地图。无论我做什么,我都无法显示地图。
正如您可能猜到的那样,我对谷歌地图不熟悉,所以我们非常感谢您的帮助。我设置了一个缩放,包括“溢出:可见”,这是另一个建议,等等。
希望这个小提琴起作用:https://jsfiddle.net/7cvj565j/

Google地图代码来自另一个SO帖子(Google maps - Postcode plotting),以查看我的地图代码是否破坏了它 - 这与我将要做的非常相似,并且该代码适用于很多人。< / p>
希望这很清楚。提前谢谢!

告诉我你对这种方法的看法!
似乎比从另一个StackOverflow帖子中获取谷歌地图代码并尝试使其工作更好。

iframe选择最简单,但我认为你需要JS版本。 https://jsfiddle.net/scorpio777/af2nzqh1/
这可能不适合您,因为API密钥不正确,或者它与您正在使用的div和样式有关。 在地图上放置地图的最简单方法是搜索Google地图上的位置,根据需要自定义尺寸,并将嵌入代码设为iframe。
1. Search the wanted location on Google maps
2. Choose "Share or embed map" from the top-right "hamburger" menu
3. Choose "Embed map" tab > "Custom size"
and you have the iframe code.
