Javascript 谷歌地图-数据库中的多个标记-phpsqlajax-Java

我正在尝试从数据库中获取不同的标记以渲染到前端。 std标记都很好，现在是添加红色、绿色标记等的时候了。我的头在这个键盘上敲击的时间太长了。（是的，我是新来的-对不起）

在JavaScript控制台中，我得到一个错误

在-var customIcons={

这是我的代码-（提前感谢！）

问题在于，当您引用google maps API的3.5.9版时，您编写的代码是针对版本2的。版本3中不再有GPoint类，这就是您出现错误的原因

我建议您在v3中使用google.maps.Marker类。有关更多详细信息，请参阅。
嘿，非常感谢！！我拿出了Gpoint，它可以工作了！！！干杯
