我对HTML、CSS、JavaScript和传单很陌生。
我尝试创建一个具有多个选项卡的HTML文件,在每个选项卡上,我都希望显示一个不同的映射(左侧),其中包含映射显示内容(右侧)的信息。
我发现
this
关于如何做选项卡部分的链接,我已经在地图部分有了一个工作示例,但是HTML文件上只有一个地图。
现在我试着把这两件事结合起来,但只有一张地图工作正常(第一张),其他地图只显示灰色,可能在左上角有一小块地图。但即使我试图平移“破碎”的地图,也只显示部分瓷砖。
有人能告诉我怎么做吗?一个带有传单的HTML文件上甚至可以有多个地图吗?
这是到目前为止我的HTML文件,包括HTML、CSS和JavaScript。

我知道我可以用较少的变量使用数组来做映射,但是现在我只想让这些多个映射工作。我以后会关心代码的漂亮。
