我在谷歌地图上有超过120个标记，并希望将2个圆圈绑定到每个标记。 我已经实现了这一点，但我继续收到警告： -
“停止运行此脚本？此页面上的脚本导致您的Web浏览器运行缓慢。如果它继续运行，您的计算机可能会在IE上无响应”。
我仅针对圆形叠加显示此错误。
我该如何解决这个问题？有什么方法可以优化？
以下是示例。地点不是我正在使用的确切位置，但这是我在我的应用程序中实现的方式

答案 0 :(得分：0)
它本身并不是一个错误，代码按预期运行，浏览器只是警告你需要花费大量时间并且考虑到你要求客户端渲染120个标记和240个圆圈我会说这是可以预料的。您将不得不考虑优化或重新设计您是ui为了 为了规避这个。
最简单的Google地图优化始终是实施标记聚类器，可用示例here。
或者，您可能希望重新设计功能并向标记添加过滤器？是否有必要一次显示所有点？
