google maps api multiple markers info window only showing last element

Google Maps API Multiple Markers with Infowindows
I am creating a Google Maps for a school project. Being a JavaScript newb, I got the code from a tutorial I found online. My problem is that I have an array of markers and multiple info windows, but whenever you click on a marker (doesn't matter which one), the info window only shows the content in the last element. Now I know this problem has been mentioned many times, unfortunately, I was unable to take the solutions mentioned in the other posts and apply it to my work.
我正在为学校项目创建 Google 地图。作为 JavaScript 新手，我从网上找到的教程中获得了代码。我的问题是我有一组标记和多个信息窗口，但是每当您单击标记时（与哪个无关），信息窗口仅显示最后一个元素中的内容。现在我知道这个问题已经被多次提到了，不幸的是，我无法将其他帖子中提到的解决方案应用到我的工作中。
