【问题描述】：
我正在尝试在 googlemap infoWindow 中添加一个按钮，但我是 javascript 的初学者，我已经在这方面花费了数周时间，但仍然无法正常工作......所以我希望你们中的一个能够帮助我。
稍微解释一下...我从 bdd 获取标记以在地图上显示它们。然后在单击标记时，会打开一个带有所有信息标记的信息窗口。
这一切都很完美，但是当我不明白的时候。
我已经为每个 infoWindow 标记添加了一个提交按钮，并且我希望在单击提交按钮时执行一个操作（保存到数据库）。但是按钮根本没有响应...
我删除了所有包含保存功能的代码以保持一切清晰，因为有一个警报（“点击”）来测试按钮...

【问题讨论】：
-
我在发布的代码中收到了一个 javascript 错误：
(index):79 Uncaught (in promise) ReferenceError: marker is not defined在这一行：`setMarkers(map, marker);`。请提供一个 minimal reproducible example 来证明您的问题。 -
另外：
Uncaught ReferenceError: vendorId is not defined和TypeError: Cannot read property 'addEventListener' of null在这一行：document.getElementById("submit").addEventListener("click", () => {（因为您没有提供所需的 HTML） -
好的，是的，因为这些变量是在我的 php 代码中发送的，例如我将编辑代码
