openlayers6地图切换展示(附源码下载)

前言

之前写过一篇openlayers4版本的地图切换效果，但是由于是封装一层 js代码写的，很多初学者看起来比较有点吃力，所以本篇文章重新写一篇地图切换效果，直接基于最新版本openlayers6写的，纯粹html + js + css形式，没有任何封装。

内容概览

1.基于openlayers6实现地图切换展示效果
2.源代码demo下载

效果图如下：

大概实现思路如下：地图初始化配置加载各种在线地图，比如天地图，arcgis地图，谷歌地图，高德地图，百度地图，OSM地图等等，默认图层只显示一个地图，其他在线地图默认隐藏不可见状态；js自定义一个底图切换的控件，底图切换时候，动态设置图层的隐藏以及可见性，达到底图切换目的。
