我有一个带谷歌地图javascript的静态html网站。我想在地图上添加标记，但我坚持使用48标记。之后，标记不会显示在地图上。我认为对谷歌地图设置最大字符/标记可能会有问题。有谁知道有最大标记号？如果是，我可以以某种方式向地图添加更多标记吗？
到目前为止，这是我的剧本：

对于用户体验，您不应在地图上添加太多标记，但有很多方法可以向地图添加大量标记，例如

答案 1 :(得分：1)
几乎晚了五年，但我在这里发布了一个回复，询问谁能用最大数量的标记来试验一些问题。
在大多数情况下，我认为您没有最大数量的标记（我已经尝试使用大约 600 个标记并且效果很好）。当地图显示标记时，您只需尝试延迟即可。性能问题是为什么在地图上添加许多标记不是一个好习惯的原因。
但是，如果您使用带有自定义图标的特定标记（例如 .svg），您可能会遇到一些困难。要绕过此问题，您需要在构建标记时禁用默认设置的优化渲染属性。为此，只需在每个标记中添加“优化：假”行：
var marker = new google.maps.Marker({
position: myLatlng,
map: myGmap,
icon: {url: mySvgIconUrl},
optimized: false
});
有关它的更多信息，您可以查看文档的这一部分：https://developers.google.com/maps/documentation/javascript/markers#optimize
