我已经阅读了有关“Infowindows未显示”的所有关于stackoverflow的帖子。在创建信息窗或任何意外声明之后创建地图不是问题。
地图显示标记,它可以计算路线,但是当您点击标记时,它不会显示任何信息窗口。这是我制作的整个程序的一小部分,但我已经使它可以重现,以便您更好地阅读它。 (API-Key未显示)

感谢您的帮助。我遇到这个问题已经好几天了。
编辑:
在Firefox的控制台中,它会输出“TypeError:a is undefined”。在main.js:17:1612
在Chromium的控制台中,它打印出“Uncaught TypeError:无法读取未定义的属性'__e3_'”。在main.js:17
JSFiddle无法正常工作(没有找到错误,这是我第一次使用它):https://jsfiddle.net/oamjue5p/2/
答案 0 :(得分:0)
正如geocodezip所说,
carMarker是google.maps.Marker而不是数组,
未捕获的TypeError:google.maps.event.addListeners不是函数
