Google地图内容未在Bootstrap模态视图中显示
你好伟大的Stackoverflow程序员，下面的代码在从页面运行时显示谷歌地图但是当我将它嵌入到引导程序模式时，它只显示地图的形状而没有显示任何位置。你可以看到附加的图像。请有人帮助我
那个。
由于

答案 0 :(得分：1)
我在下面的代码中修复了一些问题。注意＆＃34; CHANGE＆＃34;评论中的文字。基本问题如下：
- 制作一个div，它是地图div的父级，并控制该div的可见性，而不是地图div。通过使地图的div最初隐形，我相信它会弄乱地图。控制其父级的可见性，您不会遇到此问题。
- 将地图创建汇总到函数调用中，并且仅在您第一次要求显示模态时执行此操作。用布尔全局控制它。
这是更正后的代码。经过测试和工作：
